Engine 2115 – VAZ 2115 engine: characteristics, technical parameters, description

Most VAZ-2115 models have a four-cylinder injection engine. There are options with other engines, but the classic “fifteenth” moves precisely with the help of an injector with an improved lubrication system. They began producing such power plants in 1994. Over more than twenty years of service, they have proven themselves to be easy-to-use and reliable motors. Let's figure out what characteristics the VAZ-2115 engine has.

What does the VAZ-2115 engine consist of?

The VAZ-2115 has a gasoline engine, four-cylinder, in-line, four-stroke, with an overhead camshaft, eight-valve. The cylinders operate according to the following scheme: 1–3–4–2, counting from the crankshaft pulley. The system is powered through electrically controlled distributed fuel injection.

The engine, together with the clutch and gearbox, form a power unit in the engine compartment - a block on three rubber-metal supports.

The cylinder block is made of cast iron. The nominal diameter is 82 mm, it can be increased by 0.4 or 0.8 mm during repairs. The cylinder class marking is marked on the bottom plane in Latin letters according to the cylinder diameter in millimeters. The permissible level of cylinder wear is 0.15 mm per diameter.

The cylinder block contains five bearing supports, which are bolted to the block. The covers are not interchangeable, since the holes for the bearings are modified in the assembly with the covers. To distinguish them, they are marked on the outside with marks. Thrust half-rings in the middle support prevent axial displacement of the crankshaft.

There is a steel-aluminum half-ring installed in the middle, and a yellow metal-ceramic one at the back. In this case, their grooves face the crankshaft. If the crankshaft play exceeds 0.35 mm, the half rings should be replaced.

Thin-walled shells for connecting rod and main bearings are made of steel-aluminium. The main upper bearings of the first, second, fourth and fifth supports have a groove on the inner surface. The lower main bearing and the upper bearing of the third bearing are without grooves, just like the connecting rod bearings.

The crankshaft is made of high strength cast iron and has journals: main and connecting rod. The shaft has eight counterweights cast with the shaft. Oil is supplied from the main crankpins to the connecting rod journals through drilled channels. The channel entrances to the shaft cheeks are closed with plugs. The channels also serve for oil purification: the rotation of the crankshaft throws resins and solid particles towards the plugs under the influence of centrifugal forces. When dismantling the crankshaft, it is advisable, and before balancing it is simply necessary, to clean these channels from accumulated deposits. The plugs cannot be reused.

The camshaft drive pulley is keyed on the crankshaft at the front end. The generator drive pulley is also attached to it, which serves as a shaft vibration damper.

The flywheel is attached to the rear end of the shaft through a washer with six bolts. The flywheel is cast from cast iron and has a steel toothed ring, which serves as the engine starter.

The connecting rods are made of steel. Their cross-section is an I-beam. The connecting rods are processed together with the covers. In order not to be confused during assembly, the cylinder number is stamped on the covers. A steel-bronze bushing is pressed into the upper head of the connecting rod.

The piston pin is made of steel, tubular in cross-section. The finger rotates freely on the bosses (floating type) and is secured with locking spring rings to prevent it from falling out. They are located in grooves on the piston bosses.

The piston is made of aluminum alloy. The piston skirt has a complex shape: conical in longitudinal section and oval in cross section. Three grooves are machined for the piston rings in the upper part of the piston. There are drillings in the oil ring groove that also serve to supply oil to the piston pin. The hole under the piston pin is offset by 1 mm from the diametrical plane; when installing the piston, you need to orient yourself along the arrow on its bottom: the direction towards the shaft pulley.

In order to reduce imbalance, engine pistons in the crank mechanism are selected based on mass: the spread should be no more than 5 g.

The piston rings are located in the grooves of the piston. The upper rings are compression. These rings prevent gas from escaping into the crankcase and provide heat transfer to the cylinder from the piston. The lower ring is an oil scraper ring. The oil collected from the cylinder walls is transferred to the holes in the piston bosses and lubricates the piston pin.

The cylinder head is made of aluminum alloy and is common to all cylinders. It is centered on two bushings. Fastening to the block is carried out with ten screws. A metal-reinforced non-shrink gasket is installed between the head and the block. Its reuse is not permitted.

There are five supports located at the top of the cylinder head. The camshaft supports are detachable, and their holes are machined in assembly with the front and rear bearing housings.

The camshaft is made of cast iron. The design of the shaft is five-bearing. The camshaft is driven into rotation from the crankshaft by a toothed belt. There are marks on the toothed pulleys for proper installation. If the mark of the crankshaft pulley corresponds to the mark of the oil pump housing, then the mark of the camshaft pulley corresponds to the bent antenna of the rear cover of the gas distributor drive.

The guide bushings and valve seats are pressed into the cylinder head. The holes in the bushings are finalized after pressing. Grooves for lubrication are cut on the inner surface of the bushings: along the entire length of the intake valves, and up to half the length of the exhaust valves. Oil reflective caps placed on the bushings are made of oil-resistant rubber.

The valves are made of steel. The exhaust valves have heads made of heat-resistant steel. They are arranged in a row, at an angle to the plane in which the cylinder axes lie. The exhaust valve plate is narrower than the intake valve. The washers that regulate the valve clearance are made of 20X steel. In order to increase their wear resistance, the surface is pre-nitrocemented.

The pushers are made in the form of cylindrical cups; they move in the holes of the cylinder head and rest on the ends of the valves. In order to increase wear resistance, the surface that comes into contact with the valve is carburized. The rotation of the pushers during engine operation is carried out by shifting the cam axis from the pusher axis by 1 mm.

The valve closes under the action of springs. They rest with their lower ends on the washer, and the upper plate is held in place by breadcrumbs. Their shape is a truncated cone, and the inner surface is resistant flanges that fit into the grooves on the valve stem.

Combined engine lubrication is used: the connecting rod and main bearings and the camshaft journal-support pairs are lubricated under pressure; splashing of oil onto the cylinder walls (and further to the pins and piston rings), in the pushrod-camshaft cam pair and to the valve stems. The remaining components are lubricated by gravity.

The oil pump in the VAZ-2115 car engine is gear-type, with a pressure reducing valve, internal gearing. The pump is mounted in a housing attached to the cylinder block. The drive gear (smaller) is mounted on two shaft flats at the front end.

The oil receiver is bolted to the pump housing and the bearing cover (second main). The oil filter is non-separable, full-flow, with anti-drainage and bypass valves.

Crankcase ventilation is a closed circuit, with forced removal of gas through an oil separator.

Operating procedure

Often when repairing an engine, it becomes necessary to disconnect high-voltage wires. Some drivers, after disconnecting the wires, do not remember the order in which they were installed. As a result, there may be confusion with the wires, and if they are connected incorrectly, the car will not start. To avoid an unpleasant situation, you need to know how the internal combustion engine operates.

Connecting wires to a VAZ 2109

The principle of operation of the power unit is based on such a property of gases as the ability to expand when heated. A standard four-cylinder engine operates in 4 strokes:

1. During the first stroke, the air-fuel mixture and part of the exhaust gases are “injected”. This mixture completely occupies the volume of the cylinder.
2. In the second cycle, the “compression” process occurs. In this case, the valves are closed, and the piston moves upward due to the movement of the crankshaft and connecting rod. The working mixture fills the combustion chamber.
3. On the third stroke, called “expansion,” a spark appears thanks to the spark plugs, which ignites the working mixture. The expanding gases exert pressure on the piston and force it to move downward. Then, thanks to the connecting rod, the crankshaft begins to move.
4. On the fourth stroke, the process of “release” of exhaust gases is carried out. Through the exhaust valves they enter the exhaust system of the VAZ 2109.

In order for the operation of a multi-cylinder engine to be smooth and the crankshaft not to experience uneven loads, it is necessary that the work processes be carried out in a certain order.

There are different schemes that determine in what sequence the cylinders will function. The VAZ 2109 uses the following scheme: 1-3-4-2. The cylinders are numbered starting from the front cover of the power unit.

Cylinder numbering on the VAZ 2109

If we imagine the working process of the engine through the cylinders, then the order of operation is as follows:

1. In the first cylinder, an upward movement occurs, the working process takes place: the air-fuel mixture burns, the gases expand.
2. In the third, a “compression” process is carried out, in which the piston moves upward.
3. The fourth receives the working mixture as the piston moves downwards, thus carrying out the “injection” process.
4. In the second, the piston moves upward, while the exhaust gases exit through the exhaust valves.

Technical characteristics of VAZ 2115

The five-seater VAZ 2115 sedan, thanks to its spaciousness, has become one of the most popular family or family-country cars. The VAZ 2115 also has a large trunk, and the interior is distinguished by a thoughtful design that increases comfort.

The VAZ 2115 sedan replaced the VAZ 21099 model on the market, and compared to the latter it was more thoughtful from the point of view of transporting large volumes of cargo. Namely, access to the trunk has become easier, and it itself has become more voluminous, due to the area between the rear lights. Now this space has been “transferred” specifically to the luggage compartment.

Engine characteristics

The first copies of the VAZ 2115 were equipped with compact and economical one and a half liter carburetor engines. However, these power units were not environmentally friendly, and therefore, in order to achieve the required indicators for the environmental friendliness of vehicles, injection engines with a volume of 1.6 liters - eight- and sixteen-valve - began to be installed on the VAZ 2115. However, from the point of view of the modern consumer, who chooses not so much with his heart as with his mind - assessing the ratio of price and quality - the VAZ 2115 is inferior to other developments of the Volzhsky Automobile Plant, in particular, the Lada Granta or Lada Kalina.

VAZ-2115 is a compact city sedan from AvtoVAZ. The car went into production in 1997 and was produced until 2012. The model is an improved version of the VAZ-21099 sedan, built on the basis of the VAZ-2108 - the first front-wheel drive car in the history of AvtoVAZ. “Fifteenth” generally retained the design of its predecessors, and received only an updated exterior and interior design. The car began to look more modern, but by modern standards it does not live up to its competitors. Therefore, the VAZ-2115 was considered the cheapest car in its class. At one time it competed with Daewoo Lanos, Renault Logan 2004 and some Chinese cars of previous years, for example Chery Amulet.

Which engine is better, 1.6 16- or 8-valve?

16 classes the engines were installed in a limited series at AvtoVAZ or at the SuperAvto subsidiary. They were also installed by tuning fans themselves.

In terms of manufacturability, they are superior to 8-cl. engines. Accordingly, if there is an option to take a 16-cl. motor, it would be nice to go with this option. But everything has its own nuances.

Advantages of 16-valve engines over 8-valve engines

1. The best cylinder blowing is more power.
2. More stable engine operation - less noise.
3. Greater efficiency means lower fuel consumption.

However, 16th grade. the engine (1.6 l) from Priora (21126) bends the valves when the belt breaks. For some reason this scares many people. You just need to monitor the condition of the car, belts, rollers, pump, then everything will be fine! On all modern cars the valves bend.

Description

The VAZ 2115 engine was developed on the basis of engine modification 21083. The only differences are the presence of an injector, which replaced the aging carburetor, a modified camshaft and a floating connecting rod pin.

• In total, the new engine turned out to be 6 horsepower more powerful than its predecessor. At the same time, the power unit has become more responsive and provides confident traction at various speeds. Like its predecessor, this engine has a belt drive, which somewhat complicates maintenance work.
• If the belt breaks, the valves do not bend, which eliminates the need for complex repairs. The motor itself turned out to be quite reliable and has a service life of 150 thousand kilometers. When following all service recommendations and careful operation, mileages of 200 and 300 thousand kilometers are not uncommon.
• The four-cylinder engine is cast from a durable cast iron alloy, which improves temperature resistance. It is practically not subject to overheating, which allows you to operate the car in difficult conditions and under maximum loads.
• In general, impressions of the VAZ 2115 engine are positive. It is moderately powerful, reliable and easy to maintain. However, you shouldn't expect miracles from him. From 1.5 liters of volume, VAZ engineers managed to extract only 78 horsepower. Whereas engines of similar volume in modern cars produce at least 100 horsepower.
• The average fuel consumption, which is 7.3 liters in mixed mode, also does not shine. This engine is also not without characteristic breakdowns, which, although not critical, can cause a lot of problems for the car owner.

VAZ 2115 engine stalled: causes and methods of correction

The VAZ 2115 engine suddenly stalled, the starter turns, but the engine does not grab.

There are quite a lot of reasons that can cause the VAZ 2115 engine to stop. If we assume that there is gasoline in the tank, the fuel pump and starter are working normally, then first of all you need to check the integrity of the timing belt. If it is torn, it must be replaced.

IMPORTANT! If the timing belt looks intact in appearance, then it is necessary to check the condition of its teeth. If the belt teeth are licked, the belt will slip and the engine will not start. In this case, the belt must also be replaced.

The reason that the engine does not start may be a faulty crankshaft position sensor (CPS). DPKV is the only sensor in the car, due to its breakdown, the engine cannot start. Its signals, arriving at the controller of the engine control unit, allow the latter to synchronize its operation with the operation of the gas distribution mechanism. This generates signals that control fuel injection and the ignition system. Thus, the operation of fuel injectors and ignition in the fuel mixture supply system is synchronized.

Checking the DPKV begins with checking the integrity of the electrical wiring. If the wires are damaged, they are replaced.

The sensor itself is located next to the generator drive pulley. It is removed and a visual inspection is carried out. If the housing is damaged, the sensor must be replaced.

In cars of recent years of production, the “check engine” indicator located on the instrument panel will indicate the need to check the sensor. On older cars, you can check the DPKV using a multimeter. The resistance of the sensor measured with its help should be in the range of 600...900 Ohms. If the DPKV is working, then it is recommended to carry out further troubleshooting at a service station that has a special diagnostic scanner.

Fuel tank design

The main function of a fuel tank is to store a certain amount of fuel. At the same time, everything must be organized so that the likelihood of a fire hazard is minimized.

On VAZ cars the fuel tank is located under the rear seats. Due to this placement, in the event of serious accidents and car overturns, the tank in most cases remains undamaged. VAZ fuel tanks are made of leaded steel sheets. Thanks to a thin layer of lead that protects against corrosion, the service life of the tank is significantly increased. The outside of the fuel tank is covered with dark enamel.

The fuel tank, covered with dark enamel, is reliably protected from corrosion

The fuel storage volume of the VAZ 2108 and other similar models is 43 liters. This takes into account the reserve, but it is not recommended to fill the tank to the brim. You should always leave a free volume of about four liters. It is especially important to do this in the summer, since the fuel expands as the temperature rises. If the tank is filled to the brim, then after swelling it may simply burst. The volume of the VAZ gas tank is designed in such a way that the autonomous mileage is enough for 500 kilometers, and this is considered a normal road segment in modern conditions.

The tank is securely fixed to the car body using flexible and durable plate-type clamps. Rubber gaskets must be placed under the clamps to ensure a tighter connection.

The tank mounting plates are very flexible and durable

Gasoline is poured through the neck on the right (in the direction of travel) rear side of the body. It is closed with a screw cap.

The neck of the VAZ 2115 tank is closed with a tight lid

Main elements of the fuel tank

The neck is connected to the tank cavity through the filler hose. The other two tubes are integrated with a seven-liter separator installed outside the tank and designed to capture gasoline vapors. As a result of wear, the separator may split along the seam and gasoline will begin to leak out. It can be replaced without dismantling the tank. Moreover, you can temporarily cover the separator seam with a gasoline-resistant sealant.

Tuning

There are several possible ways to increase engine power. Let's talk about these tuning options in more detail:

1. Chip tuning of the VAZ 2115 engine will not allow you to obtain any noticeable effect. Even by replacing the engine control unit, the car owner will be able to get 3-5 horsepower, the increase of which will be almost imperceptible.
2. Deep engineering tuning of VAZ 2115 engines, which involves replacing the camshaft and other power elements, will increase the engine power to 85 horsepower. Such an increase of 10 horses will already be noticeable, and the car will accelerate faster, especially from low revs.
3. Replacing the throttle body and exhaust will increase power to 95 horsepower.
4. If the engine power limit of 100 horses is important to you, then you need to install lightweight valves, mill the cylinder head and replace the intake manifold. A car with such a tuned engine will accelerate 1-2 seconds faster than with a basic 78-horsepower engine. A further increase in power by replacing internal power parts will not allow you to obtain the desired horsepower, and the service life of the motor is significantly reduced.
5. An alternative way to increase the power of a VAZ 2115 engine is to install a compressor with a pressure of about 0.5 bar. If the compressor is properly configured, the engine power will be about 120 horsepower. At the same time, when resorting to such tuning, the car owner must be prepared to reduce the service life of the engine, which may require appropriate major repairs after only 75-100 thousand kilometers.

Possible causes of failure

During the operation of the internal combustion engine, various malfunctions are possible. To detect them, you should perform the following sequence of actions:

1. First you need to start the car. The engine should idle. At this time, you should listen to what sounds are coming from the exhaust pipe. If you hear regular popping noises, then one of the cylinders is faulty. The cause may be faulty spark plugs and lack of spark. The malfunction can also be caused by a large amount of incoming air or insufficient compression in the cylinder.
2. It is necessary to inspect the candles. If there is carbon deposits, moisture or oxidation, you need to clean it. Check the gap between the electrodes, which should be 0.8 - 0.9 mm.
3. Replace all spark plugs, regardless of their appearance and vehicle mileage.
4. If there are irregular emissions, you need to inspect the high-voltage wires. There should be no traces of oxidation on their tips, and the insulation should not be damaged. If defects are found, the wire should be replaced.

Wires connecting to the coil

• The gas distributor cap should be inspected. There should be no soot or cracks on it. The carbon contact should be checked for damage and wear.
• The rotor needs to be inspected. It must be solid and have no signs of burnout. All parts with defects must be replaced.
• The pressure in the cylinders is allowed to be no lower than 1.1 MPa, and the compression difference should not exceed 0.1 MPa. If the indicators do not correspond, engine repair is necessary.

If after the above steps the problems remain, then you need to contact a service station to undergo a more accurate diagnosis of the VAZ 2109 engine and adjust the ignition system on the stand.

VAZ 2113 (2114, 2115) - model description

VAZ 2113 – Produced from 2005 to the present. It differs from the previous model with modified body panels and interior.

History of the creation of the VAZ 2113

The car and its modifications appeared in the Volzhsky Automobile Plant model range as a restyled version of the obsolete VAZ-2108 family. By 2005, the level of comfort that cars of the VAZ 2108 family could provide, against the backdrop of an ever-increasing flow of foreign-made cars, ceased to be competitive. In view of this, it was decided to switch to the production of a restyled family of cars while maintaining the same body. This family was supposed to occupy the lowest price niche in the VAZ model line after the final discontinuation of the “classic” models.”

Technical features of the VAZ 2113

The “Thirteenth Model” and its modifications are produced in the same body, but with modified hinged panels, such as the trunk lid, fenders, hood and others.

The interior, compared to the first front-wheel drive family, has changed quite a lot - panels, ceilings, door cards, dashboard and instruments themselves - all of this has been modernized for installation in the new model.

The VAZ 2113 engine was initially installed the same as on the 2108 - an eight-valve transverse engine with a distributed injection system. In 2007, engine capacity increased to 1.6 liters. When equipped with a new engine, the car complies with Euro-3 standards.

In 2010, a limited number of models of the family began to be equipped with a sixteen-valve VAZ-21124 engine with a power of 90 hp from the VAZ 2110 and a forced VAZ-21126 (98 hp) from the LADA Priora. With these engines, the car's rated maximum speed is 185 kilometers per hour.

Modifications of VAZ 2113

Just like in the previous 2108 family, the car is available in three modifications. In addition to the three-door hatchback, the VAZ 2114 model, which replaced the VAZ 21093, is on the assembly line of the Volzhsky Automobile Plant. It differs from the previous model 2114 in the design of the front part of the body with new block headlights, PTF, a modified hood, fenders, radiator grille, other plastic bumpers, moldings and a spoiler , painted in body color.

VAZ 2114

There are also significant differences in the interior design. For example, the VAZ 2114 has a height-adjustable steering column, which was not present in the 2109.

It is noteworthy that 2114 appeared earlier than 2113 - the first car of this model rolled off the Togliatti assembly line in October 2001. Since 2007 (due to stricter standards for the amount of harmful substances in the exhaust), the car has been equipped with a modernized 1.6-liter VAZ-11183 engine that meets Euro-3 requirements. The model receives the VAZ-21144 index.

VAZ 2114

The updated engine is equipped with a new phased injection system to improve efficiency.

Not only the power plant was subject to changes, but also the interior: the car was equipped with a more modern and less noisy dashboard (popularly nicknamed “Europanel”), with an on-board computer, VDO instruments with two liquid crystal displays. The computer shows not only the trip parameters and fuel consumption, but also the outside air temperature, voltage in the on-board network, time, and so on.
