Technical characteristics of the VAZ 21127 1.6 16kl engine

Design features of the Lada 21127 16 valve engine

The donor for the new power unit was the already well-known VAZ 21126 engine. The main difference from its predecessor is the use of a modern intake system with flaps. Let us briefly describe the principle of its operation. Air enters the cylinders in different ways: at high speeds it is directed along a long path, and at low speeds it is directed through a resonance chamber. Thus, the completeness of fuel combustion increases: i.e. power increases - consumption decreases.

Another difference is the abandonment of the mass air flow sensor in favor of DBP+DTV. Installing a combination of absolute pressure and air temperature sensors instead of the mass air flow sensor saved owners from the common problem of floating idle speed.

Otherwise, this is a typical VAZ injection 16-valve unit, which is based on a cast iron cylinder block. As on most modern Togliatti models, there is a lightweight Federal Mogul ShPG, and the Gates timing belt is equipped with an automatic tensioner.

Signs of the need for internal combustion engine repair

The reasons why the operation of the engine is disrupted are arranged in a small list, starting with refusal to start and ending with floating idle speed (this problem was removed on the 127 “engine”). Not all breakdowns end in capital damage - sometimes it’s enough to add oil, sometimes it’s enough to adjust the ECU settings.

Compression reduction

A decrease in cylinder compression below 16 atmospheres is a bad sign. Such a high limit corresponds to a compression ratio of 11.

If the compression decreases (or vice versa increases), then the “engine” will have to be rebuilt.

Knocks in the engine

Engine knocks can come from several points. These could be hydraulic compressors, timing belt rollers or pins. The knocking noise could also be caused by low oil level. The answer to the question will be given by a thorough detailed inspection of all parts of the unit and checking the oil level.

Blue smoke from the exhaust pipe

The blue smoke that comes from the exhaust pipe appears when oil enters the combustion chamber. It can leak either from the valves or from under the piston. The result is the same: the oil is eaten up and blue smoke pours out of the chimney. Once the leak is located, half the problem will already be solved.

Troit motor

Sometimes in the cold the engine may stall - don’t be alarmed by this, because it may simply be one of the spark plugs that fails. In this case, we advise you to simply restart the engine and it will stop running.

How much does it cost to overhaul a Priora engine - average price

Self-repair of a Priora engine with 16 valves costs an average of 16-20 thousand rubles. The cost depends on the severity of the breakdown and may be lower or higher than this average range. Repairing a Priora engine can be entrusted to the wrong hands, but then you will have to pay for the work - sometimes the cost of repairs reaches as much as 40 thousand rubles.

This is an unreasonably inflated figure, because, as practice shows, you can rebuild the engine on a Priora, working at a moderate pace, in just three days - and three days of work is definitely not worth that kind of money. Don’t be afraid of not being able to cope - your Lada is easy to repair, and using the advice and “tutorials”, you will conquer even such a task that is impossible at first glance.

Specifications

power 21129 (127) – 106 hp. (21126 – 98hp)

Torque 21129 (127) – 150 N.m (21126 – 145 N.m.) at 4000 rpm.

Mixed fuel consumption is 7-10 liters per 100 km. More details about fuel consumption

Recommended fuel – AI 95

Motor weight – 115 kg.

The table above shows the torque and power graph of the 1.6L 21129 engine and its comparison with the 21179 1.8L engine.

Engine tuning

Initially, engine 21127 had already received factory tuning, but there were still opportunities to further increase power:

• In addition to the standard receiver, a damper with a diameter of 54 mm is mounted to achieve a performance of about 110 liters. With.;
• another 10 l. With. will be added by replacing the exhaust catifold with a “spider”;
• The Stolnikov camshaft modification 8.9 will provide power in the upper speed range.

Tuning 21127

Complex tuning is possible by installing a Stolnikov 9.15 camshaft with a phase shift of 316 degrees, replacing injectors with Bosch 431 360 (more efficient compared to standard ones) and milling the valve seat stages. In this case, the internal combustion engine will receive about 150 hp. With.

Thus, motor 21127 is an industrially tuned version of the previous internal combustion engine 21126. The characteristics are improved only by modifying the intake air system (damper inside the receiver plus DBP, DTV).

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.

Description of engines

All engines that were supposed to be installed on Lada Vesta cars are in-line 4-cylinder power units assembled practically according to the same scheme. They are equipped with a 16-valve DOHC gas distribution mechanism with two overhead camshafts. The sequence of cylinders is: 1-3 -4-2. The service life of each of these engines before the first major overhaul is no less than 200 thousand km.

Important! A common drawback of all VAZ engines, the gas distribution mechanism of which is driven by a belt - when it breaks, the valves bend.

However, despite the similarities, each of these power units has a number of differences:

• VAZ-11189 is part of the line of well-known VAZ engines: 21083/21114/21116/11186. It differs from the prototypes in the modified design of the intake and exhaust. The engine is the simplest and cheapest of the engines ever used on the Lada Vesta. Currently it is not installed on this model, since its technical characteristics turned out to be insufficient for a fairly heavy car.
• VAZ-21129 - installed on Lada Vesta cars from the first days of mass production to the present day. Can be combined with a robotic gearbox. It is an analogue of the VAZ 21127 engine, distinguished by the presence of a number of new components:

1. Exhaust gas intake and exhaust system.
2. Calibration controller for engine management and dynamic charging systems (the volume of the intake manifold can be changed using special dampers).

Modernization of the engine made it possible to reduce:

1. Fuel consumption.
2. Noise and vibration levels during operation.
3. Exhaust toxicity.

VAZ-21179 is a new engine for the Lada Vesta. According to experts, it is most suitable for cars of this class.

The Lada Vesta engine differs from other power units:

1. Increased cylinder capacity.
2. New crankshaft.
3. Torque 127 Nm at crankshaft speed 1000 rpm. In addition, the engine's gas distribution mechanism is equipped with the first domestic phase shifter. Due to experiments carried out with this phase shifter, the motor lay “on the shelf” for a long time. The appearance of a modification of the Lada Vesta car with a 1.8 liter engine. expected soon.

HR16DE-H4M is a motor developed by engineers of the Renault-Nissan alliance. Since 2005, its serial production has been mastered at OJSC AvtoVAZ. The Nissan Lada Vesta engine differs from domestic power units in a number of features, including:

1. Installing the phase shifter on the intake shaft.
2. Using electronic throttle.
3. Availability of a variable valve timing system.
4. Chain drive of the gas distribution mechanism.

The undoubted advantage of the engine is the ease of tuning, with which you can increase power and improve its technical characteristics. How to carry out tuning, what parts need to be installed, as well as the type of new firmware for the Lada Vesta engine can be found out by watching the video

The disadvantages of the Lada Vesta engine include:

1. The absence of hydraulic compensators for the valves of the gas distribution mechanism, which requires regular (on average every 90 thousand km) adjustment of thermal clearances during operation.
2. Inability to install a robotic gearbox.

VAZ-21203 is one of the most interesting VAZ engines. Its prototype first appeared in 1998 and was intended for the Nadezhda minivan (VAZ 2120). Despite the fact that the car did not go into production, work on the 2-liter engine continued. Over many years of experimental work, it was possible to develop a number of non-standard technical solutions, which formed the basis of the new “well forgotten” motor.

The engine is versatile - it can be installed in both classic rear-wheel drive cars and more modern front-wheel drive ones. Serial production of the VAZ 21203 engine is expected to be carried out at the pilot production facilities of AvtoVAZ OJSC. The only obstacle that needs to be overcome during pre-production is that the life of the VAZ transmission is not designed to work together with a powerful power unit.

Features of 21129 engine/differences

The main feature of the 129 engine is the “innovative” for AvtoVAZ installation of an intake receiver with variable chamber geometry and volume. Due to the damper, the volume of the intake chamber changes depending on the speed. As practice shows, the damper is activated at 3500 engine speeds.

In addition, the engineers managed to get rid of the mass air flow sensor - mass air flow sensor. Along with him, his ailments went away, which tormented the owner of the 21126 engine: unstable idling, sometimes exorbitant consumption, high cost. Instead of mass air flow sensors, engineers installed a connection from DBP and DTV sensors (atmospheric pressure and air temperature sensors). This is where the differences from the 126 engine end. Speaking in fact, the intake system with variable geometry is as old as the world and has been installed by global manufacturers almost since the 80s.

The main disappointment in the car: A motorist spoke about the problems with the 1.6 106 hp engine in the LADA Vesta

The VAZ engine is the anchor that prevents Vesta from becoming a modern car.

The main complaint about the 1.6 liter VAZ-21129 engine with a capacity of 106 horsepower, designed and assembled by AvtoVAZ, is its archaic nature. This opinion was shared by a motorist on the YouTube channel “LADA Vesta Blog” after 4 years of ownership. But even this LADA Vesta has its advantages.

Archaic and problematic “129th”

“The engine seems to pull the car into the past. Because of it, the Vesta is not perceived as a modern car,” says the “newsman,” noting the outdated design and “outdated” technologies and build quality.

Because of this, car owners have to face a lot of problems:

• “Dips” at the “bottoms” and uneven operation of the engine at idle.
• Problems with launches. It is especially necessary to “turn” the starter several times in hot and cold weather.
• “In winter it cannot warm up completely, and in summer it overheats in a couple of minutes,” notes the driver.
• Uneconomical "appetite". The average consumption in mixed mode for the 1.6-liter engine is 7.9 l/100 km, which is 1 liter more than in the passport data.
• The unit does not have enough traction when the air conditioning is on and the interior is loaded, especially on the highway when overtaking.
• Needs constant improvements and maintenance. Over the course of 4 years, the vacuum tubes of the support were repeatedly changed, and the fitting was sealed with an additional silicone ring inside to soften the “twitching”. The throttle assembly was cleaned; it “easily and easily” became clogged with dirt and oil. The oil filler cap was replaced due to leakage, and along with it, the emergency oil pressure sensor was replaced.

New LADA Vesta FL 2021-2022: What is known about restyling today

LED optics, a tablet a la Tesla in the cabin and a more powerful engine - these are the innovations the updated Vesta will boast. The platform and overall design have not changed, but a lot of cosmetic ones have appeared... Three advantages of archaism
Among the advantages of the “anchor”, motorists note its reliability, provided that the oil, filters and timing kit are changed in a timely manner. The engine surprises with its service life, reaching 300-400 thousand km without capital. The maintainability, simplicity and low cost of servicing the unit is enviable.

The engine lends itself perfectly to “chipping” and boosting up to 130-150 “horses”, if you want to “experiment”.

However, the “newsman” noted that now, having experienced all the shortcomings of the “archaic” engine, I would take the Vesta with a 1.6-liter 113-horsepower unit from Renault paired with a CVT.

In addition, the constant “tugging” of the manual transmission lever is a thing of the last century; even the “blunting robot” is more progressive and provides more comfort than the “handle”.

Engine tuning 21129

Tuning the 21129 engine is no different from the 126 engine.

Easy tuning : Euro-2 or Euro-2 firmware + installation of 4-2-1 exhaust

Medium tuning : Exhaust 4-2-1 + Shafts + firmware (preferably flashed online)

Deep : includes modification of the head, replacement of valves, pushers, etc. All technical characteristics of Vesta.

Guys, with which engine is it better to take 126 or 127 (106 hp)? About the Priora 1.8 with an engine of 128 (124 hp) the reviews are bad, that they bring it to the service in tow, the timing roller gets stuck.. In general, let's discuss which engine with is it better to take?)

You need to know the service life of Lada Vesta engines

Characteristics of the Lada Vesta car

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.

5. Increased fuel consumption, unstable operation, sluggish acceleration from more than 15 to hundreds - the oxygen concentration sensor (lambda probe) may be broken.
