Estimation of actual engine life for Lada Vesta 1.6, 1.8

AvtoVAZ pleases us with its innovations from time to time. For a long time, the VAZ series, from the cheap Lada to the stylish S7, was very popular. Later, the Lada Samara line appeared, represented by the VAZ-2108, VAZ-2109 and VAZ-21099. They were supplemented by the model range of cars of the 10th family. Now we are content with Kalinas, Grants, Priors and Vestas. Some of these models began to be equipped with a new power plant - engine 21127.

What prompted you to take such a step? And how can the new engine surprise domestic car enthusiasts now?! Let's try to answer these and other questions.

One of the differences

The new engine is based on the previous version of the internal combustion engine - VAZ-21126. The company did not plan to make any fundamental changes, however, there are serious differences.

The main feature is the use of a modern intake system with flaps, thanks to which air enters the cylinders a little differently. When the engine revs high, it travels a long way. At idle or low speeds, air first enters the resonance chamber. As a result, the fuel burns completely, which leads to improved performance of the VAZ-21127 engine.

Now under the hood of the car there are already 106 “horses”, although the engine volume remains the same – 1.6 liters. Moreover, this applies not only to high, but also to low speeds. And here you might think that with an increase in power, fuel consumption also increased. In fact, the efficiency remains the same. This is the same 6.7 liters per hundred kilometers.

Short description

The VAZ-21127 engine can be used for installation in LADA Priora, Lada Kalina 2 and Lada Granta cars. On LADA Vesta and LADA Xray cars, this engine comes with the index 21129 (a new control unit for Euro-5 and adaptation for a Renault gearbox). The VAZ-21127 internal combustion engine is an improved modification of the 1.6-liter VAZ-21126 engine. The VAZ-21127 engine is almost no different from the VAZ-21126 engine. The main feature is that the VAZ-21127 engine, unlike the VAZ-21126 engine, is equipped with an adjustable intake (the original intake system with a resonance chamber and a damper system). Engine characteristics were improved, power increased from 98 to 106 horsepower, torque increased from 145 to 148 N•m. It was possible to obtain up to 10 N•m of torque increase in the range of 1000-3500 rpm. The engine control controller has been redesigned and has completely new calibrations. In general, the engine has more than 20 new parts; an absolute pressure sensor is installed instead of the mass air flow sensor.

Second feature

Another feature is the replacement of the MAF (mass air flow sensor) in favor of other devices - DBP and DTV. Thanks to the coordinated work of the duo of absolute pressure and air temperature sensors, floating speed in idle mode of the engine is not dangerous.

Otherwise, it is the same injection-type power unit with 16 valves (four for each cylinder). As for the base, the block has not undergone any changes since the VAZ-21083. The designers equipped the gas distribution mechanism drive of the Lada 21127 engine with an automatic tensioner.

Ignition switch and features of its replacement

The ZZ is secured with one screw and is located on the steering column on the right under the steering wheel. Its design includes a locking device and a contact group. They are interconnected, working synchronously, and are activated using the ignition key.

When diagnosing faults in the electrical circuit, it is necessary to check whether the contacts close correctly when the position of the key changes. If any irregularities in the operation of the ignition protection are detected, it should be replaced (the author of the video is Renault Repair).

The procedure for replacing the ZZ on the Lada Largus consists of the following steps:

  1. Before work, disconnect the negative terminal from the battery to turn off the power supply to the car.
  2. Next, remove the steering column casing.
  3. At the next stage, by releasing the latch, we disconnect the connector with the wires of the contact group.
  4. Then, inserting the key into the ignition switch and setting it to the first position, remove the 33 wires from the dashboard.
  5. Next, unscrew the bolt that secures the ZZ.
  6. Use a screwdriver to press out the latches and remove the 3Z from the housing.
  7. We dismantle the faulty unit.
  8. Having installed a new spare part, we assemble it in the reverse order.


Kit for Lada Largus After replacement, we check the operation of the ignition lock by changing the position of the key.

Advantages

What's so good about the new engine? There are several advantages worth highlighting here:

  • All attachments are optimally located, which significantly reduces labor costs for vehicle maintenance and repair.
  • Due to the special design of the intake manifold, the power unit operates in a stable mode, and the idle speed does not “float”.
  • Not only the power has been significantly increased, the torque is now also greater - 148 Nm instead of 145 Nm.

The line of motors 21127 has been expanded by the manufacturer. But, perhaps, an invaluable advantage is that the engine is equipped with a new product in the form of a receiver with inertial supercharging.

Design changes

The 21127 engine was created from the previous modification 21126 of the 2112 engine, so the main design remained the same:

  • cylinder head – used from the first version 21124;
  • gas distribution mechanism – DOHC scheme, two camshafts, phased injection;
  • cylinder block – high type from 11183, cylinder surfaces are honed;
  • connecting rod and piston group - lightweight, foreign made;
  • Timing drive – belt, tooth profile rounded;
  • exhaust tract - catalytic collector with a large landing size of the neutralizer;
  • crankshaft - with a “long” crank radius, from 11183;
  • flywheel – has a chamfer for a large diameter damper;
  • ignition system – there is a separate coil for each spark plug, there are no high-voltage wires;
  • fuel system – ramp with imported injectors (Siemens, Bosch);
  • electronic motor control system – controllers M7.9.7 or January 7.2;
  • attachments - a pump with a metal impeller has a long service life.

Fuel rail 21127

“As a legacy”, the 21127 engine received ultra-low oil consumption - only 0.1% of the amount of oil used by the system. However, for the operation of the valve and hydraulic lifter cooling system, the AvtoVAZ manufacturer’s operating manual recommends purchasing exclusively high-quality lubricant, which costs 10% more.

Flaws

Despite the improved characteristics of the 21127 engine, there are also weaknesses. And the main disadvantage is the vulnerability of the valves. If the timing belt breaks, they can easily be bent by the pistons. Another equally pronounced disadvantage is the high cost of engine repairs. Moreover, it does not matter where and who will do this: professional service station technicians or the vehicle owners themselves.

The high cost is mainly due to the fact that the timing belt, automatic tensioner and pulley included are very expensive. This is due to the fact that they are manufactured by the foreign manufacturer Gates. The same applies to ShPG parts, which are also produced by a foreign, but different company - Federal Mogul.

Engine 1.6l 106hp 21129

In this article we will talk about the 21129 motor, which replaced the Priorovsky 21126 motor, we will talk about its differences from its predecessor, and its problems. This motor is installed on Grants, Kalinas, Priors. Vesta will also receive this engine, and already from the first batch. The 129 engine is the same 127, but with different firmware in order to comply with Euro-5 toxicity standards, thereby making it possible to sell Vesta in Europe.

Basic list of faults

As the domestic manufacturer assures, the resource of the power unit is 200 thousand kilometers while maintaining operational properties. Nevertheless, even such a perfect design of the 21127 engine does not exclude the occurrence of various malfunctions. Friction can often be observed, however, this is typical for most modern power units. This mainly indicates clogged injectors. Washing them gives the desired result.

Problems with electronics can also occur. Often the people who suffer the most are:

  • ignition coil;
  • starter;
  • electronic control unit;
  • fuel pressure or idle speed regulator.

Sometimes you can hear knocking noises from the engine compartment. You should not put off inspecting your car indefinitely; it is better to immediately determine the source of the extraneous noise. It is likely that the sounds are made by hydraulic compensators, and then there is nothing to worry about.

You should panic if the cause of the knocking is not in these parts. With a greater degree of probability, this may indicate wear of the connecting rod and piston group.

Oil

The oil used in this engine is similar to 21126: synthetic, semi-synthetic

5W-30 5W-40 10W-40 15W40

Oil sump volume

This point will be useful for those who are going to change the engine oil. With different transmissions, the volume of oil poured into the engine is also different.

VAZ 21129 + Renault manual transmission (cast crankcase) = 4.4l

VAZ 21129 + robot (stamped crater) = 3.2 l

The engine resource is 200 km. But in practice, you need to monitor the condition of the roller, pump and timing belt, because if individual valve elements jam, they will meet the piston group, and then both will come to an end. In addition, during the impact of these elements, it is not uncommon that the crankshaft bends slightly. You can drive with such a crankshaft, but there will be huge oil consumption.

Serious damage

According to the manufacturer Gates, the service life of the timing belt is 120 thousand kilometers. However, during the operation of the 21127 engine, this is not always confirmed. In most cases, the culprit is the idler pulley, which causes the belt to break. And this already leads to more serious consequences: the valves bend. The threat of a major overhaul can be avoided by replacing the standard pistons with plug-in counterparts.

Unfortunately, the quality of domestically produced thermostats remains unchanged over time. Therefore, their breakdown is still the most common cause of car overheating. It should be noted that such an engine also does not tolerate frosts well. In this connection, some prudent drivers have to cover the radiator with cardboard during winter operation of the car.

The declared resource of 200 thousand km will justify itself only if maintenance is carried out in a timely manner and consumables are replaced.

Also, do not ignore the first signs of any malfunctions in the VAZ-21127 engine. Otherwise, you will have to prepare for capital investments. Sometimes it's easier to just buy a new car outright.

Why was the 27th engine replaced with the 29th?

The VAZ-21127 engine was good for everyone, except for one thing - it complied with Euro-4 standards. For Vesta sedans produced since November 2015, this option would not be suitable. It was necessary to solve a difficult problem: to improve the environmental class without increasing the volume and without losing power. And as a result, a new family of 16-valve engines appeared in the VAZ arsenal. We are talking about motors 21129 - they really meet the latest environmental standards.

The first Vesta engine, produced by VAZ

To move to the Euro-5 standard, engine 21127 had to be modified:

  • The resonant intake system, as well as the exhaust system, have been completely redesigned;
  • The ECU controller (ECM) has received new firmware - even the algorithm that regulates the volume of the resonant chambers has been changed;
  • Engines 21127 and 21129 have slightly different compression ratios - 11.0 versus 10.45;
  • The engine suspension was also improved: it became possible to mount it on a subframe.

It is clear what kind of engine the Lada Vesta would have had in 2015 and later if not for the transition to Euro-5. It would be the VAZ-21127 internal combustion engine, but with a modified suspension. And now we see that almost everything has been improved. As they say, changes are obvious.

What happened to the resource?

The resource value for the VAZ-21127 engine is 200 thousand km. In reality it is more. The engine must run all these “thousands” without replacing parts: only the belt tension is checked, the oil is changed, and there is no need to replace the timing belt.

Timing belt, VAZ-21127

There is no need to “adjust the valves,” since the 16-valve engine is equipped with hydraulic compensators. Everything that is said here also applies to the latest VAZ development - the 21129 engine.

Note that the 27th and 29th engines do not differ much, while the second of them is operated in a more gentle mode. And this means that its resource will be at least no less than that typical for the ICE “21127” - 200 thousand and above!

What exactly has changed in the design?

In appearance, motor 21129 looks very modern. In its design, for example, there is a pressure sensor (DBP) combined with an air temperature sensor (ATS). The damper of the resonator chambers is controlled by a pneumatic drive.

All these elements are also present in the design of another engine - the VAZ 21127. And it was possible to improve the performance without increasing the displacement using the following methods:

  • The “piping” was redone - exhaust, resonant intake, controller program;
  • The design uses lightweight pistons: an alloy with aluminum is used for manufacturing, the piston skirts are shortened, and recesses are made in the bottom for the valve plates;
  • Both compression and oil control rings have become thinner than on all previous engine models. Friction losses have decreased.

Maintenance

If you maintain your car on time, the chances that you will avoid major engine repairs are high. It is better to play it safe and avoid high costs, not only financial, but also time. A lot of nerves will also be spent.

  • A timing belt can last 180 or 200 thousand kilometers, but it needs to be inspected much more often.
  • The oxygen sensor has a slightly shorter service life - no more than 100 thousand km.
  • The entire cooling system, like the liquid itself, will serve properly for 40 thousand kilometers.
  • It is recommended to change spark plugs every 20 thousand kilometers.
  • The oil filter along with the lubricant must be changed even more often - at least every 10,000 kilometers.

Cylinder head repair

We mark all hydraulic compensators with numbers using an ordinary clerical touch and put them away. An ordinary magnet will help you pull them out. We dry out the valves and remove the oil seals (valve seals), the valves into scrap metal, the oil seals into the trash. We clean all channels. We take the head for grinding, just in case. After washing it again with kerosene after sanding and blowing it with air, we begin to assemble it.

We arrange the freshly purchased valves in the sequence in which they will stand in the cylinder head and begin to grind in one by one. Lubricate the valve stem with clean oil and apply lapping paste to the edge.

We insert the valve into place and put a valve grinding tool on the valve stem. The stores sell a device for manual lapping, but since this is the twenty-first century, we are mechanizing the process. We take the old valve and cut off the rod from it, select a rubber tube for it of such a diameter that it fits tightly. The rod is in a reversible drill, one end of the tube is on it, the other is on the valve being ground in. At low speeds we begin to grind the valve, constantly change the direction of rotation and periodically press it to the seat or weaken the force. On average, the valve takes about twenty seconds. We take it out and wipe it. The valve is considered ground in if a uniform gray strip of at least 1.5 mm wide appears on the chamfer.

The same stripe should appear on the valve seat.

Video of manually grinding valves

For a sixteen valve head, everything is the same, only there are twice as many valves. After lapping, all valves and seats are thoroughly wiped and washed with kerosene to remove any remaining lapping paste. We check for leaks. We tighten the old spark plugs and put all the valves in place. Pour kerosene and wait three minutes, if the kerosene does not run away all is well, otherwise we grind the valves on this cylinder.

We had to grind four valves again, after which the kerosene stopped flowing.

We stuff new valve seals.

We put the valves in place and dry them. Before doing this, lubricate the valve stems with clean oil. After lubricating it with clean oil, we put the hydraulic compensators in place and, covering them with a clean cloth, remove the head out of sight. We're done with the cylinder head.

Useful tips

Since the weak link in the cooling system is the thermostat, it is necessary to carefully monitor the antifreeze temperature, which should not exceed +95...+98 °C. Otherwise, premature wear of parts cannot be avoided.

When replacing the oil filter yourself, you need to pay attention to the valve cover seal. The presence of smudges indicates an unsatisfactory technical condition of the gasket. Because of this, motors often overheat.

Some car enthusiasts prefer to increase the power of their vehicles through chip tuning. True, as a result of flashing the control unit, no special increase in power is expected - only five horsepower.

The 21127 engine can be significantly benefited by installing Stolnikov 8.9 camshafts with a phase of 280. As a result, the car will accelerate to hundreds of kilometers per hour in less time - 9 seconds. Speed ​​lovers will be pleased.

Maintenance

The actual life of the internal combustion engine is still unknown due to the short service life of the first cars that will roll off the assembly line in 2022. However, to increase it, engine 21179 should be serviced according to the regulations below:

  • 10,000 km means changing the filter/oil;
  • twice as long, the alternator belt runs 30,000 km;
  • after 45,000 km, change hoses/fittings and antifreeze;
  • spark plugs and batteries are enough for 60,000 km;
  • About 180,000 the original timing belt passes.

For 2022, the internal combustion engine device is considered the most advanced in the AvtoVAZ manufacturer’s line. In practice, his project had been considered since 2006, but was constantly postponed until the technical, economic and market situation in the Russian Federation finally developed favorably. That is, AvtoVAZ in this project prioritized the power output of the engine, and not economical fuel consumption, as was usually the case before.

Public opinion

As many owners of 2nd generation LADA Kalina cars equipped with the new engine note, they actually felt an increase in power. This was especially noticeable at low speeds. It takes 11.5 seconds to accelerate a car to a speed of 100 km/h, and this is a great merit for domestic transport.

As other reviews show, the 21127 engine worries a number of owners, which is associated with an already pressing problem - a high risk of timing belt breakage. But here you need to either come to terms with this state of affairs, or replace the pistons, as already mentioned above. A break is dangerous not only because of bent valves; other parts can also receive serious damage.

Is it possible to tune the Priora 126 engine?

Even with a strong desire, the 126 engine will not be able to reach a speed of 100 km/h in a few seconds. Without tuning the Lada Priora engine, overtaking prestigious brands will also not be possible.

According to many motorists, it is necessary to install a turbocharger from the very beginning. In this case, the engine power will increase by no more than 15 - 20%. Special filter elements are additionally installed here to clean the cold air as it enters the engine.

The main improvements to the 21126 motor are:

  • cylinder boring;
  • increase in piston stroke.

With the help of these modifications, it is possible to most effectively boost the 126 engine, the power of which increases by 50 horsepower. The main purpose of boring is to increase the volume of the cylinders. The process comes down to primitive actions:

  • cylinder walls are reduced in thickness;
  • more gasoline is burned in the resulting volume;
  • engine performance increases;
  • power increases.

When choosing a future car, we definitely pay attention to what kind of power unit (heart) it has. Not only the dynamics depend on the motor, but also how much money is required for its maintenance

Do you know which modern VAZ engine to choose?

Let's look at a table with the characteristics of all engines that the manufacturer installs on modern Lada cars (Granta, Kalina, Priora, Largus, Niva, Vesta and XRAY):

So which engine is better for a modern Lada car? There is no definite answer, but there are a number of parameters by which one or another power unit can be distinguished from others:

If the decisive factor when choosing a car is engine power, then you should pay attention to the last two columns of the table with the VAZ-21127 (106 hp) and VAZ-21126-77 (120 hp) engines. For those who are worried about a broken timing belt and the consequences (bent valves), we recommend the oldest engine from the presented VAZ-11183 line. If one of the main characteristics is accelerating a car to 100 km/h, then it is worth considering the VAZ-21127 engine with a manual transmission, where acceleration to hundreds will take only 11 seconds. Interested in the potential for engine tuning to increase power? Then consider 16 valve engines. Previously conducted surveys on Lada.online and Kolesa.ru:

By the way, we have already talked about modern VAZ engines from a different perspective in this review.

Modification

Thanks to the efforts of many designers, the power unit 21127 complies with the Euro-4 environmental standard. High performance indicators make it possible to equip some models from the Lad family with such an engine: Lada Priora, Lada Granta and Lada Kalina. However, the environmental standard is undergoing changes, and in connection with this, a new version of the engine was developed - 21129.

This modification of the 21127 engine complies with the Euro-5 standard, and now LADA Vesta cars and the LADA XRAY crossover are equipped with this engine.

What is the most important thing in a car? Wheels, interior, and maybe suspension - We believe that when choosing a car, everything is important. But the engine is the most important factor when deciding to buy a car. The Lada Vesta is powered by 3 modern engines from AvtoVAZ. Any car enthusiast would be curious to know in detail about each of them.

In total, the review material will consider three main types of engine:

— engine 21129 from VAZ — technical problems, characteristics; — 21179 from VAZ — the new top-end 1.8 engine is installed on the latest modifications, including the Lada Vesta SW Cross; The HR16DE-H4M propulsion system from Nissan is a chain motor with an impressive resource, but manual valve adjustment.

Cylinder block

The block is cast from high-strength cast iron. Cylinder numbering is carried out on the installation side of the crankshaft pulley. Each cylinder, based on the results of measuring its diameter, is assigned a size class.

Block 21126 is painted gray. Wall processing is carried out in accordance with the requirements of Federal Mogul. Block 21126 has three classes every 0.01 mm (A, B, C). The cylinder class mark is located on the bottom plane of the block.

AvtoVAZ pleases us with its innovations from time to time. For a long time, the VAZ series, from the cheap Lada to the stylish S7, was very popular. Later, the Lada Samara line appeared, represented by the VAZ-2108, VAZ-2109 and VAZ-21099. They were supplemented by the model range of cars of the 10th family. Now we are content with Kalinas, Grants, Priors and Vestas. Some of these models began to be equipped with a new power plant - engine 21127.

What prompted you to take such a step? And how can the new engine surprise domestic car enthusiasts now?! Let's try to answer these and other questions.

What engine is installed on the Lada Vesta

The main engines for the Lada Vesta, which are installed by the manufacturer, are already indicated in the introduction. The company's decision to refuse to install the VAZ-11189 engine in the basic configuration was a winner. It seriously idles even on Grant and Priora; in fact, it is a modification of the VAZ-11186 model known to many. The only difference is that it has different intake and exhaust valves. The decision is due to the heavier body of the new car and increased requirements for the driving characteristics of the installed engine. There are three types of installations with different characteristics installed on cars. Two with a volume of 1.6 liters. and one 1.8 l. At 21179 AvtoVAZ had to increase engine power by 14 horses, without increasing appetite.

While writing this review, they traveled thousands of kilometers and we are ready to talk about the results. Recently, a wave of discussions was caused by the fact that one of the engines was not developed by VAZ, but will be supplied by Japanese manufacturers. Moreover, instead of the usual timing belt, it has a chain and it has more power. This allows you to seriously increase the power output of the motor. Is a chain better than a good engine belt?

Main technical characteristics of VAZ engines: 21124,21126,21129,21179 and their comparison

Boring a VAZ-21179 leads to sad results. There are no repair pistons, and an attempt to line the block, due to additional drilling done between the cylinders, for better cooling of the block, is not possible.

Comparison of engine 21179 with base 21126

The VAZ 21124 engine, unlike 21222, 21126, 21129 and 21179, does not bend the valve; for this purpose there are holes on the bottom of the piston. It can be used with standard shafts or sports ones with moderate lift,

Starting with engine 21126, the piston was reduced, thinner rings were installed, and the connecting rod was lightened. The 21126 engine is already equipped with a new automatic timing belt tensioning mechanism with rollers of a new design.

Many car owners with this engine had their timing belt break and valves and connecting rods bent at very low mileage, due to poor quality pumps assembled at TZA. Pumps or rollers jammed, which led the car owner to significant expenses (from 30 to 50 thousand rubles). At the same time, the belt could easily cover its 150-200 thousand km.

A special two-layer metal cylinder head gasket with a thickness of 0.45 mm was also installed.

At 21179, we increased the working volume to 200 “cubes” and installed a phase shifter at the inlet. Thus, the base 21126 was increased from 98 to 120 horses. Naturally, it was necessary to somehow reduce the thermal load. To do this, it was necessary to make additional cooling channels in the cylinder head, which AvtoVAZ did an excellent job with. 21179 has a new cylinder head with increased fluid flow. But to reduce the temperature in the cylinder block, they did it in a simpler way. The block had the usual oblique drilling between the cylinders. Is the question still open? Will the gasket between the cylinders often burn out due to additional holes?

This practice has already been used on ZMZ engines. When from a 406 engine with 98 hp. made 405,135 hp. We also machined a jumper into the block. The result was disastrous. The cylinder head gasket burned out very often and many drivers began to seal these jumpers with cold welding. So, West drivers from 21179, get ready and stock up on cold welding (just kidding).

Subsequently, ZMZ completely changed the cylinder block and the new engines 405 and 409 already came without a jumper between the cylinders. The plant admitted its mistakes, but more than one thousand gazelle drivers have experienced these factory mistakes. AvtoVAZ cannot yet replace the old cylinder block from 21126 with a new one developed by the designers, due to the too high costs of changing the production cycle. I think in the future they will be forced to replace the unit.

At 21179, the crankshaft was lightened by 40%. Now its stroke will not be 75.6 as it was on 21129, but 84, so the pistons and connecting rods are no longer interchangeable with 21126.

The oil channel plugs on the crankshaft were removed and a neck-to-neck lubrication system was used.

The main bearings do not have a full groove for oil passage, but have a variable profile.

The intake manifold and valve covers are completely plastic.

A rubber gasket was used in the crankshaft damper to dampen torsional vibrations.

There is a new flywheel for the clutch with a diameter of 215 mm, not 220, as was previously the case.

The pump produced by TZA was completely replaced by an imported supplier, apparently Korean.

Europeans make all their engines through one place, and Russian managers, thanks to peripheral capitalism, are good at adopting this experience. When some talkers say that the Russians cannot do anything, this is pure lies and propaganda. We still have great specialists in the automotive industry, but they are caught in the grip of the current economic situation, where it is practically impossible to apply their knowledge and projects. What the USSR did in 1939, the Germans were able to repeat only in the 90s. An example is the V-2 diesel engine with 4 valves per cylinder with two camshafts, which was installed on the T-34 and could even run on sunflower oil. Those designers who then developed an engine that was an order of magnitude superior in its performance to the German engines on the Tiger and Panther tanks need to erect a monument.

Motor VAZ 21129

Let's talk about the first of two Russian models. There are quite a few differences between the 129 engine and the 127 Priorovsky, the youngest in the model range. In comparison with the VAZ-11186 engine, with a volume of 1.6 liters, it has a power of 106 horsepower. This difference is due to 16 valves instead of 8 in the previous version. Ambient temperature sensors and absolute pressure sensors are installed as standard. Characteristics of this Lada Vesta engine.

Power - 106 horsepower, spins up to 5800 rpm. Volume - 1.6 l. A highly modernized engine mount has been installed. Drive and timing type: standard DOHC timing belt. Torque characteristics - 1484200. Motor weight - 109.2 kg. Cast iron cylinder block Electronic ignition system controlled by a processor. Adds dynamics to the car. Fuel type is unleaded gasoline with an octane rating of 95, but 92 is also possible. Power supply is via a distributed injection system. The car will accelerate to 100 km/h from 21129 in 12.8 seconds. With a 129 engine, Vesta consumes gasoline: in the city - 10.2 liters, mixed driving - 7.5 liters, on the highway - 6.2 liters.

Toxicity is at a level characteristic of the Euro 5 standard.

The running life is set at 200 thousand km.

Innovations compared to the design of the previous model monitor the quality of fuel, and do not idle. The damper system regulates the air supply at different speeds, which gives traction to the engine from the bottom and at the top.

Motor 126 and 127: working life, differences

These engines on Priora had a displacement of 1.6 liters (or 1596 cm3). Optimal for city sedans, the engine size of the Lada Priora gave a good combination of dynamics and consumption: along with very decent acceleration, fuel consumption does not exceed sky-high numbers. Both engines received good marks, because the car behaved perfectly in the city and on the highway.


127 motor - looks like this

In fact, the 126 Priora engine became the first sixteen-valve engine for this model, and the 127 is a modified version, “overclocked” by AvtoVAZ designers. In addition to the same engine displacement, they have other identical characteristics. The in-line type of arrangement of four cylinders provides a simplified design that can be repaired on your own.

The distributed multipoint injection system is involved in creating a good, rich fuel-air mixture (a lean mixture can lead to breakdowns). The cylinder diameter is 82 mm, the piston stroke is 75.6 mm, the compression ratio is 11. The “engines” fall under the Euro 4 standard, they are powered by gasoline with an octane rating of 95.

The 126 engine for the Priora received the following characteristics: 98 hp. (72 kW at 5600 rpm), acceleration to 100 km/h in 11.5 seconds (with manual transmission), city consumption 9.1 l - 100 km (manual transmission), maximum torque - 145 Nm.

The 127 engine for the Priora was upgraded to the following figures: 106 hp. (78 kW at 5800 rpm), acceleration to 100 km/h in 11.5 seconds (with manual transmission), city consumption 8.9 liters per 100 km (with manual transmission), maximum torque – 148 Nm.

The difference may not seem so noticeable, but this is a very small but strong step in design on the part of AvtoVAZ (this is where the change to sixteen-valve “engines” with a volume of 1.6 liters ended). For a car of the Lada Priora class, the engine power was sufficient.

In the same block it is necessary to say about the operating temperature. An absolutely normal operating temperature is considered to be between 90 and 95 degrees Celsius. Further, when the car is being pushed in a traffic jam, is basking in the sun, or for some other reason, but can still work - from 97 to 110 degrees. The engine is slow in places and wears out a lot, but you can still get to your destination. A temperature below 90 degrees is a direct sign indicating that the car has not yet warmed up, and it is better to wait in place until the arrow points to the coveted 80-90 mark.

In general, the service life of the Lada Priora engine with a normal driving style and careful treatment is 200,000 km - after this mark the time comes when the “engine” requires major repairs. AvtoVAZ mentioned the timing belt separately as a recommendation, saying that it needs to be checked every 100,000 km (many car enthusiasts talk about the figure of 50,000 km).

All Lada engines have a problem, and it is related to the valves, which will be discussed further.

Motor VAZ 21179

This engine option was the first in the line with a volume of 1.8 liters. produced since 2016. Externally similar to competitors, but inside there are a lot of design features characteristic of the 179 model. Vesta with a 1.8 liter engine installed 21179. is much more dynamic and powerful than his less productive colleagues.

Characteristics of 21179 engine:

Power - 122 horsepower, spins up to 6050 rpm. The most powerful of our line. Volume - 1.8 l. It is assembled using a selective conveyor method. Drive and timing type - a German device from INA is installed for tensioning a toothed belt. The belt will need to be replaced after about 90 thousand km. Torque characteristics - 170/3750. Motor weight - 110.1 kg. Higher than competitors, but the difference is not noticeable. Block material is cast iron. Electronic ignition system controlled by a processor. The fuel used is similar to the previous version, AI-95 gasoline. Using a 179 engine, the car will accelerate to 100 km/h in 12 seconds. Fuel consumption: in the city - 10 l, mixed type of movement - 8 l, on the highway - 7 l. Toxicity - Euro5. No different from others, despite significantly different parameters. The running life is set at 300 thousand km, which significantly exceeds that of the 129 model.

As advantages of the engine, we note the following: - The 179 engine is installed on the long-awaited Lada Vesta Cross by many car enthusiasts. The power and driving characteristics are enough to not have any problems driving; — fast and confident driving and start from traffic lights;

— design feature for changing gas distribution phases; — lightweight and enlarged intake (31 mm) and exhaust (28 mm) valves were used; — standard AMT VAZ transmission is used. Some of the components were not made in Russia, but were manufactured by leading automakers. For example, the valves are made by Mahle, and the oxygen sensor is made by Bosch.

The disadvantages of the engine are higher fuel and oil consumption compared to the other two power plants. Valve bending (like other options in the line), resulting in a high noise level when operating in any gear. The last circumstance is typical for engines installed in Lada Vesta.

Engine Renault-Nissan H4M-HR16 DE

This engine, produced by the joint company Renault and Nissan, is not equipped with a timing belt. A chain is installed instead. You can save quite a lot on consumables, their purchase and replacement. After all, a good belt complete with rollers costs from 4,500 rubles. Let's talk about the main characteristics of the unit:

Power - 114 horsepower. Volume - 1.6 liters, like the 21129 engine. Type of drive and timing - instead of a timing belt, as previously written, there is a chain. The only drawback is the moment, there are no hydraulic compensators in the design, which means approximately every 100 thousand km. mileage will require valve clearance monitoring. Like 2109 in 2018! Torque characteristics - 153/4400 Motor weight - 109.1 kg. Cylinder block material is aluminum. Electronic ignition system controlled by a processor. Fuel types - AI-92, AI-95, methane. There is more choice than others, although I doubt that our people only put 95 gasoline in 179 and 129, anything that burns is used!

Power supply using a distributed injection system. The car will accelerate to 100 km/h with the H4M-HR16 DE in 12.2 seconds. Gasoline consumption: in the city - 8.2 liters, mixed driving - 6.3 liters, on the highway - 5.4 liters. Toxicity is at the level of the Euro 5 standard. Running life is 250 thousand km.

It has the highest cost among the three units. An excellent choice for those who value power and comfort at the same time. By operating Vesta with a Nissan engine, we get high power and low fuel consumption. The solution for driving in the city and those who regularly make long trips. The durability indicator is also extremely high with adequate use and regular maintenance - running-in practice shows that its service life is much longer than that of VAZ competitors. However, with careful use, all three motors will show a longer service life and the engine will endure repairs. The disadvantages of the h4m-HR16 are the unusual nature of its timing component and high requirements for oil quality.

The compression ratio of the engine determines what kind of fuel is required for refueling. If the SG is less than 10, this means that AI92 gasoline is suitable. If the compression ratio is greater than 10, only give 95; on our units, only the H4M-HR16 DE came closest to 11.

  • 21129 has a compression ratio of 10.5
  • 21179 -10,3
  • hr16de -10.7

Advantages and disadvantages

The advantages of the 21129 engine are:

  • economical consumption of coolant, engine oil and fuel;
  • compliance with Euro-5 standards;
  • improved attachments;
  • overhaul on your own;
  • declared resource 200,000 km;
  • absence of periodic adjustments of valve thermal clearances.

To ensure the specified motor life, the manual recommends using only high-quality lubricants from reliable manufacturers. The disadvantages of the power drive design are:

  • expensive maintenance due to the need for high-quality oil in hydraulic pushers;
  • high capital repair budget due to the use of ShPG and timing belt kits from foreign companies;
  • there is a danger of bending the valves if the timing belt drive breaks.

The compression ratio has decreased by 0.5 units, which seems to reduce the octane number of the fuel. In practice, the quality of domestic gasoline is unsatisfactory; experts do not recommend experimenting for dubious savings in the operating budget.

Lada Vesta engine life - you need to know

Life tests of the units installed on Vesta allow us to say that the overall impression of them is rather good.

We have already mentioned what resource the factory installs in the description of each motor; here we will briefly write:

— VAZ 21129 resource — 200,000 km; — motor life of the VAZ 21179 engine is 300,000 km; — resource hr16de from Nissan — 250,000 km.

Tuning is available in a wide variety of designs. Excellent options for tuning measures to improve driving characteristics would be the installation of a lightweight crankshaft and forward air flow. You can install an additional turbine; after modification, you need to improve not only the engine, but also other components of the car.

The main malfunctions and ways to eliminate them are:

1. An unpleasant whistle under the hood - most likely the timing belt has stretched and is close to breaking. It is better to replace if possible;

1.1 Unpleasant bubbling noise under the hood - the hr16de chain may have stretched and requires attention; 2. The engine stalls regularly for no apparent reason - a likely scenario is that the relay in the ignition unit has failed. It can be repaired during a recall campaign for defective vehicles; 3. At medium speeds, a characteristic nasty sound occurs - the gasket in the exhaust pipe has burned out or is burning out. Replacement is easy, especially if you contact the ASC; 4. The appearance of such a phenomenon as vibration - in VAZ engines this is a design flaw associated with the right airbag. Replace and the problems will disappear.

Priora with a 127 -129 engine: The real operating principle of the 127 receiver (part 2)

There was a video about a major overhaul of the Priora, where you can go, it also needs repairs

3GIFTS TO DIGGING!!1 Where did you go Little Bear? We missed you . 1 

Vlas listen, you might like it!! https://vk.com/audios197866438?performer=1&q=rgLed%2C%20The%20Ambolt%2C%20Zomg 

This is EVIL at the end!))

damn, they make Hondas too *_*

don't be a jerk..everything is fine..like!))

lies. I have a 127 engine with e-gas and variable geometry and this is not a 129 at all. After replacing the exhaust and calibration, she drove 100 km/h in 8.3 seconds according to the navigator. 

Improvements to the VAZ-21129 also included increasing the rigidity of the cylinder block, lubrication system, fuel injection, mounting of additional units, engine mount, exhaust system and a set of engine control elements. The new engine is designed for Euro-5 and adapted for manual transmission from Renault. 

thanks. I've been waiting for this video about 127res for 2 years. decided. 

Hello Vlas. Please tell me I have a car Kalina 1.6l 8kl engine with E-gas. I cut the head inlet 32 ​​outlet 30. The oil channel was plugged. The intake and exhaust remained unchanged. Gasoline zhor became 13-14L if the slipper is on the floor. 14.7 mixture. Will the original injectors be enough for this? 

“. there is such a bullshit, the speed of the flow of air mixing of this bullshit. “Just loudly)) 

Vlas jokes aside, you need to supplement good strength at AvtoVAZ

Our vases will soon be overtaken by donkeys

Vlas, you're obsessed, develop your ideal motor, I'm sure you'll succeed :)

X. I have a stock 106 hp with the same receiver, with the stock exhaust I don’t leave these 126 alone

The plant is pursuing efficiency and ecology, trying to preserve torque as much as possible. This system is of little use for a burner. 

Does Vlas want to poop?

It’s interesting to see about Vesta tuning.

like for the fucking microphone

The 126 motor on the bellows valve corresponds to Euro-3, the 126 on e-gas corresponds to Euro-4, but is still a 126 Prioro motor with the same beloved 98 horses. A 127 engine is a 126 on e-gas plus a fucking receiver with variable geometry = 106 hp, and a 129 engine is a 127 of pure water, only a Logan gearbox fits it. that's it guys) 

Reliability, weaknesses, maintainability

Reliability

The reliability of the engine is eloquently evidenced by the fact that the resource declared by the manufacturer is almost doubled. According to reports from car owners, there are engines with mileage of more than 350 thousand km without any significant repairs.

All car enthusiasts unanimously claim that with timely and high-quality maintenance, the VAZ-21129 is reliable and economical. You can read about this many times in the reviews of participants in various specialized forums.

For example, VADIM writes: “...1.6 engine mileage 83,500 km. Fuel consumption: city 6.5 - 7.0, highway 5.5 -6.0. Depends on the speed, quality of gasoline, and also on the build quality of the engine itself. There is no oil consumption, no topping up from replacement to replacement.”

Roman has the same opinion. He reports: “... I drive a Largus Cross 5 seats, I bought it at the dealership in June 2022, the mileage is 40 thousand km, the oil in the Lada Ultra engine is 5w40, I try to change it every 7000, during this time I don’t notice waste, oil consumption, from outsiders noise - the hydraulic compensators are knocking, and even then, in the first three or four seconds after starting in frost of -20, I don’t consider this critical, the engine is familiar from the Priora, it loves speed and does not consume much fuel.” Alexey adds: “...an excellent engine, it pulls well from low to low on the highway, low consumption of 5.7 liters!”

Well, those car owners who ignore timely maintenance, skimp on technical fluids, and really abuse the engine, can only sympathize.

As an example, the bewilderment of Soar Angele: “...Vesta 2022 mileage 135t km engine 21129 chip tuning done, forward flow on 51 pipes, tires R16/205/50 holder. There was a consumption of 10 liters in urban style, then suddenly the consumption increased to 15 liters per 100...”

Or like this. Razrtshitele from Vologda wrote the following opus: “... about engine speeds: the problem is that when the car is rolling at a speed of 5 km/h, it is difficult to get into 1st gear, but it’s easy to get into second gear. You stick it in, try to drive and drive with tension...”

For what??? Why stick into first gear if the car is already moving? To check the reliability of the engine and transmission? Comments, as they say, are unnecessary.

Issues of internal combustion engine reliability are constantly in the field of view of the manufacturer. Thus, in August 2022, the piston group was modified. The result was the elimination of the phenomenon of bending of valves when they come into contact with the piston.

Conclusion: The VAZ-21129 is a completely reliable engine if treated appropriately.

Weak spots

They are available on the VAZ-21129, but it must immediately be emphasized that they are not critical.

Complaints about the operation of the cooling system are caused by a poor-quality thermostat.


The main culprit for overheating is the thermostat.

There is some truth in this. It happens that the thermostat stops working, which can cause the engine to overheat. Or vice versa, it takes too long to warm it up to operating temperature. Both are bad.

In the first case, there is almost a 100% prerequisite for a major overhaul; in the second, prolonged but increased wear of the rubbing surfaces of the CPG will lead to the same result. There is only one way to solve the problem - to detect the malfunction in time and immediately take measures to eliminate it.

Timing drive. The operating life of the drive belt is set by the manufacturer at 200 thousand km. According to reviews, the figure is real and is maintained. The same cannot be said about the idler pulley and water pump. They usually fail by 120-140 thousand km, jam, and cause the drive belt to break.

The result is bent valves and a major overhaul of the engine. To prevent this from happening, it is necessary to change the timing components before the appointed time (90-100 thousand km).

The phenomenon of engine tripping brings a lot of trouble to car owners. In most cases, the cause is faulty spark plugs or ignition coils, or dirty injectors. Electrical parts need to be replaced, and injectors need to be washed.

Sometimes car enthusiasts are alarmed by loud knocking noises from under the hood. As a rule, their “authors” are hydraulic compensators, which quickly wear out when using low-quality oil.

Considering that hydraulic compensators cannot be repaired, they will have to be replaced. If the warranty period of the internal combustion engine has not expired, it is under warranty, free of charge. Otherwise, be prepared to shell out some cash. This will be a reason to calculate what to save on. Engine oil or repair.

As we can see, in most cases, engine weaknesses are caused by car owners themselves with their careless attitude towards the engine.

Malfunctions: causes, elimination

Despite the fact that the 16 valve engine 21129 with adjustable air intake flows and hydraulic valve clearance compensators is considered a very reliable power drive, malfunctions still occur:

Gasoline consumption has increased1) catalyst is clogged
2) fuel pump failure

3) the air filter is clogged

1)cleaning the exhaust system
2) pump replacement

3) cartridge change

Glow type ignition
(operation after switching off)
1) overheating
2) carbon deposits on the surfaces of valves and combustion chambers
1) repair of the cooling system, refilling of coolant
2) flushing of the system
Emergency pressure indication1) wear of the oil pump or main bearings
2) sensor malfunction

3) circuit closure

4) oil level is insufficient

1) replacement of consumables
2) installation of a new sensor

3) wiring repair

4) adding oil

Reduced cravings1) DPKV breakdown
2) clogged filters

3) COURT firmware failure

4) clutch wear

5) timing adjustment failure

1) replacing the crankshaft position sensor
2) replacing filters

3) flashing

4)replacement of a set or disk

5) phase adjustment, belt replacement

The 21129 engine rarely violates idling speed conditions due to the redundant adjustment system.

Real indicators based on reviews from car owners

The standard 1.6-liter engine is paired with a 5-speed manual transmission and a robot. The quality of the transmission as a whole does not cause any complaints from owners. Also, drivers often wonder what kind of gasoline is best to fill in the Lada Vesta? The manufacturer recommends refueling only with 95-octane gasoline; this information can be found in the vehicle documentation. This is important to take into account, because the nominal resource was determined taking into account many indicators, in particular, taking into account the octane number of the fuel.
