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.

- Acceleration to 100 km/h - 10.5 s.
conclusions
The design of the 8-valve injection engine VAZ-2114 is quite similar to the first generations of this engine - “Samara”. Of course, the designers made many changes to the features of the power unit, but in many ways they remained similar. Repair and maintenance of this engine must be carried out regularly, which will not only extend its life, but also reduce wear on the parts located inside.
The VAZ 2115 engine, like all engines in the series, has fairly high technical characteristics and reliability. Thus, throughout the history of production, several variants of engines produced by the Volzhsky Automobile Plant were installed on the vehicle.
Which engine is better: 1.5 liter 8-cl. or 1.6 l 8-cl?
When choosing a car, people often ask the question: “Which engine is better?” In our case, everything is not so simple. A similar question may arise if we consider buying a car from already “shaggy” years: 2006-2007. It was during this period that VAZ-2113, 2114 and 2115 were equipped with both 1.6 liter and 1.5 liter engines, the characteristics of which are outlined above.
In fact, they are no different, except for volume, exhaust standards, fuel supply systems and a pair of sensors. Therefore, the main distinguishing point is the engine size. A difference of 0.1 liters gives more torque from the bottom, adds a little maximum power and, perhaps, the same or even lower fuel consumption than 1.5 liters. The only negative is that it is noisier at idle.
Previously, in the years 2008-2012, people were reluctant to buy 1.6 liter models, saying they were loud, prone to breakdowns, etc. In fact, it is superior to the 1.5 liter engine in all respects. Accordingly, we recommend it to you. But this applies to 8-grade students. motors that were installed serially. Next, let's look at 16-cl.
Service and Frequently Asked Questions
The design of the 2115 engine allows the car enthusiast to carry out vehicle maintenance with his own hands. The service interval is 13-15 thousand kilometers. For those who want to preserve the engine longer and extend its service life, it is recommended to reduce the period of scheduled maintenance to 10,000 km.
In addition to the scheduled oil change, other diagnostic work should be carried out on the VAZ 2115 engine at each service center. For example, it is necessary to visually inspect the engine for leaks, check the condition of the timing belt and diagnose the performance of all systems and sensors. It is worth remembering that good maintenance extends the life of the engine.
FAQ
After looking through the forums and talking with auto mechanics, we can come to the conclusion that owners of the VAZ 2115 engine with 8-valve injector ask the same questions every time. Let's try to take into account the data obtained, and then group the questions and give answers to them.
- Do valves bend in a VAZ 2115? — As with any other vehicle, of course it’s oppressive. This happens when the timing belt breaks. To prevent this from happening, it must be changed every 45-50 thousand kilometers or if failure is suspected. It is worth noting that it will not only bend the valves, but also damage related elements, and may also leave a mark on the pistons. In any case, this will lead to a major overhaul of the power unit.
- Where is the engine number on the VAZ 2115? — As in all Lada models, you can find the engine number on the gearbox side, near the thermostat. The engine number always has a pad on the cylinder block, which is located in a visible place.
- What is the oil volume in the 2115 engine? — The engine oil volume is 3.5 liters. But, with this question, car enthusiasts ask another one - What oil is best to fill in the 2115 engine? — The most recommended motor oil for the engine is considered to be 10W-40. Also, auto mechanics recommend using 5W-30 and 5W-40. In this case, the oil manufacturer remains at the discretion of the vehicle owner.
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
- The best cylinder blowing is more power.
- More stable engine operation - less noise.
- 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.
Engine modification and tuning
Tuning the VAZ 2115 engine is divided into two substages - mechanical modification and chip tuning. The first option involves boring the cylinder block and installing an engine kit. But, as practice shows, mechanical tuning of the VAZ 2115 ends with superficial modifications to the engine.
For example, by installing silicone pipes, as well as a “zero” resistance filter. Although there are motorists who go all the way and do a complete mechanical tuning of the engine.
Chip tuning of the VAZ 2115 is carried out according to the scheme. The car enthusiast chooses one of the options: increasing power, reducing consumption or balanced, and after that the auto electrician programs the electronic engine control unit to the desired result.
The development of modern technologies makes it possible to carry out such an operation independently, without trips to a car service center. It is worth remembering that one awkward movement can lead to the engine working incorrectly or not starting at all.
Electronic control unit
This block monitors information coming from sensors and is responsible for controlling the fuel injection system. The control unit contains a diagnostic system, thanks to which a system failure is recognized. It signals all problems occurring in the system through a light located on the dashboard - Check Engine. It also stores all errors that have ever occurred. Subsequently, their codes help to understand when diagnosing problems.

Main settings
This engine was based on the power plant from the VAZ-21083, which was modified by replacing the carburetor with an injector. In addition, the designers updated the floating dipstick finger and camshaft. As a result of all the changes, the engine was 6 horsepower more powerful than its predecessor. It provides confident traction at any number of revolutions.
However, the remaining flaw is the preservation of the belt drive, which complicates the maintenance and repair of this power plant. However, if the belt breaks, the valve covers do not bend, which reduces the likelihood of the need for expensive and complex repairs.
The reliability of the power plant used on the VAZ-2115 is due to the fact that the manufacturer has specified a resource for it of 150,000 kilometers, which in practice is usually significantly exceeded - motorists drive from 200 to 300 thousand before major repairs. This was achieved through the use of a durable cast iron alloy that does not overheat. This engine behaves ideally in difficult temperature conditions.
You can watch the full test drive of this engine in the video. The impressions from it are positive, but you shouldn’t expect much from this power plant: with a volume of 1.5 liters, the engine power does not exceed 78 horsepower. More modern engines of similar volume receive 25 more horsepower.
Fuel consumption is also far from ideal - 7.3 per 100 kilometers if the car is used in mixed conditions.

Improvement of the VAZ-2115 engine
You can increase the power of the power plant on the VAZ-2115 in several ways:
- Don't expect much from chip tuning. This procedure will increase engine power by a maximum of 5 horsepower.
- In order for the car to accelerate faster, it is necessary to carry out deep engineering modifications. In this case, you can get an engine power of 85 horsepower, which will already be noticeable to the car enthusiast.
- After replacing the throttle body and exhaust, the power rises to 95 horsepower.
- If you want to achieve 100 horsepower, you need to install a lightweight valve system, install a new intake manifold and mill the cylinder head.
- A compressor with a pressure of 0.5 bar can make your engine almost twice as powerful (up to 120 horsepower).
Remember that engine tuning can significantly reduce its life. In such cases, major repairs will be required after 75 thousand kilometers.
