The line of "ten" VAZ originates from the sedan 2110 (1995). Three years later, the assembly of the 2111 station wagon was launched, and a year later the production of hatchbacks began.
At first, the 2110 model was equipped with a sixteen-valve one and a half liter engine. Those in those days were the maximum capabilities of a well-known car factory.
But time goes on and progress, including automotive, does not stand still - another car appears, VAZ-2112, 16 valve. The hitherto known eight-valve version had less dynamism and power. And the appearance of the car has become more sporty.
Complete sets "Lux" and "Norma"
The plant presented the car in two versions. Options:
- "Lux". Trip computer, alloy wheels, fog lamps, headlight cleaning system.
- "Norm". Power windows for all door windows, central locking, height-adjustable steering column, immobilizer, remote trunk release.
None of the equipment included air conditioning, which is a significant disadvantage in assessing comfort by today's standards. It is because of this that many drivers preferred used foreign cars to VAZ.
Body features
The appearance and body structure have undergone some changes. VAZ-2112 (16 valve engine) has become shorter by almost ten centimeters. The reason for this is the design of the rear overhang. The wheelbase remains the same. Changes:
- body length - 4 170 mm;
- height -1 420 mm;
- width - 1 680 mm.
The top of the body began to smoothly move into a rather short overhang, which is crowned with a large wing.
This design made the car better to drive, because this aerodynamics contribute to this - the performance has improved compared to previous models. Changed for the better and the appearance of the machine.
This model is in great demand among fans of tuning. The galvanized body of the "ten" family is still subject to corrosion. Therefore, the “anti-corrosion” must be performed immediately after buying the car, not counting on the reliability of the factory coating.
Interior of the car
The interior of the twelfth model has collected all the best from the previous "brothers". Changes:
- The backs of the rear seats are divided. Each of the backrests is folded (moved forward if necessary).
- The trunk has become much larger. Due to these changes, it became possible to transport long items, which summer residents like so much.
- Car owners complain that it is a bit dark in the cabin, the dashboard is not very visible.
- The assembly, it would seem, is of high quality, but still there are purely VAZ noises and panel creaks during movement.
- The power windows are controlled by buttons in close proximity to the handbrake, and this is not very convenient: it would be more appropriate to place them on car door maps. In addition, such a drive is only on the front windows, and the rear ones are opened with “oars” - handles, and even then not in the basic configuration.
- There is an almost complete lack of sound insulation. However, almost all VAZs suffer from this. Even with loud music in the cabin, you can hear the operation of the engine, chassis and the rustling of wheels.
- As for the front seats, their performance is good, although the adjustments are very inconvenient. Large people feel comfortable in this car - both the driver and the passenger on the right.
- The trunk is very convenient when loading - the shelf does not interfere.
- The driver has excellent visibility.
- The rear seats are comfortable for passengers, although the gap between the roof and the passengers' heads is small.
The pedals are pretty tight. The driver experiences the greatest inconvenience from this in winter, when the shoes are wider.
From the edge of the brake pedal to the console is a little more than 100 millimeters, and many drivers have to press the accelerator pedal with their right foot in an unnatural position, otherwise it can catch on the brake pedal. The most interesting thing is that there are no such shortcomings in the "top ten". It is very possible that the convex panel in the side of the tunnel is to blame.
The salon looks much more modest in comparison with foreign cars of the same class.
Many drivers believe that the suspension has become too soft, that is, there is no "feedback". For decades, the car owner has been accustomed to feeling every bump on the road at the VAZ - this gives confidence in driving, since the driver “feels” the road and the car.
This effect appeared due to a modified suspension system.
Nevertheless, the car is perfectly manageable, and it is felt even with a slight turn of the steering wheel. But at low speeds and during maneuvers at the very beginning of the movement, the steering wheel is heavy. ABS is not included.
The braking system is still the same:
- front disc brakes (with vacuum booster);
- drum brakes at the rear;
- braking is confident and efficient, and the system itself is simple and easy to maintain.
The car, for all its shortcomings, is still quite successful, especially if you take into account its reasonable price.
car motor
The motor was not created from scratch, but on the basis of 21083, as a result, manufacturers received a 16-valve engine, and the VAZ-2112 feels more confident with it.
The geometric characteristics of the base motor are preserved, but there are differences in power, efficiency, and throttle response. Advantages:
- Compensators are installed on the engine - now the driver is spared from adjusting valves every 10 thousand km.
- Environmental standards fit into the Euro-3 standard.
- The injector makes it possible to forget about the maintenance of the latter for a long time - there are much fewer worries than with a carburetor on the "classic", for example. This ensures smooth running of the machine in all modes.
- When the engine revs over 3 thousand, the engine has better throttle response and dynamics compared to its predecessor.
- Due to the modified combustion chamber, the anti-knock qualities of this engine have improved, and this is important, given that gasoline at gas stations is not of good quality. Such a measure of design changes extends the life of the engine until the next overhaul.
- Stable operation of the cooling system in any weather allows you to keep the desired temperature.
It is noteworthy that very famous automobile brands were involved in its creation. This, however, did not save the design from some shortcomings:
- Low torque at low rpm.
- The belt drive is not reliable and when it breaks on a 1.5-liter engine, it bends the valves, which cannot be said about a 1.6-liter engine. This disadvantage costs the car owner as a result, not cheap: you have to repair the cylinder head.
- The engine has two camshafts: intake and exhaust. They open and close valves, intake and exhaust, respectively. There are not two such valves, as on the "top ten", but four for each cylinder. This, of course, greatly improves the performance of the engine, providing a greater amount of combustible mixture to the cylinders, and there is also an improved removal of exhaust gases to the exhaust manifold. This is both an advantage of the engine and its disadvantage at the same time, since with obvious advantages in performance, its repair is more expensive. If the 8-valve engine was always famous for being unpretentious in maintenance, then the same cannot be said about the 16-valve engine.
The timing belt (timing) is longer than on the base engine, therefore more expensive. If on the previous model one pressure roller and one timing gear were involved, then on this one the number of mentioned parts has exactly doubled.
Main characteristics
The engine displacement is of particular interest to the consumer, and the volume of the VAZ-2112 engine (16 valves) can be different. There are three types in total:
- Engine VAZ-21120. Engine capacity - 1.5 liters. Power is 93 horsepower. Motor resource - up to two hundred thousand km.
- Engine VAZ-21124. Displacement - 1.6. Power - 90 horsepower. The resource is the same.
- Engine 21128. Volume - 1.8. Power is slightly higher - 98 hp. With. Piston diameter 82.5 mm. The mileage before overhaul has been increased to 250,000 km.
- Cast cylinder block, casting material - cast iron.
- The connecting rods are forged, I-section and fully interchangeable with those of the 2110.
The average fuel consumption for all engines is 7.5 liters.
As you can see, the engines are not much different, judging by their main characteristics.
How to avoid typical breakdowns?
Valve deformation due to a broken timing belt is the main “disease” of a one and a half liter engine, which requires considerable funds for its “treatment”. But, as they say, for the treatment of any disease there is a medicine.
It is enough to change the "native" pistons to those used in the 21124 model (there are samples made for the valves), and the car owner will avoid the undesirable consequences associated with disassembling and repairing the engine.
This, however, is fraught with some complications, since it is a deforcing of the engine, which will lead to a drop in power.
If the owner of his car does not want to lose power, then he needs to do the following:
- buy timing belts only from trusted and time-tested brands;
- carefully monitor the condition of the mentioned belt and, in case of the slightest defect, immediately replace it with a new one, without waiting for an unplanned break;
- you need to control the work of the pressure rollers. The slightest squeak, rustling is a signal to replace the roller.
Another very common malfunction is “floating” engine speed. As a rule, it's all about the idle speed sensor, which also needs to be replaced periodically. Unfortunately, the quality of sensors has deteriorated dramatically in recent years.
If the engine stalls when shifting gears, flush the throttle body with a special carburetor cleaner.
When the engine “troits”, then you need to check the high voltage wires (their drivers call them armored wires), the module. It would also be useful to check the compression in the engine cylinders.
Of course, you should not discount the fuel system. It is necessary to try to refuel the "correct" gasoline both in terms of octane number and in terms of its quality. As for fuel filters, you can’t install them if they are of dubious quality and from unknown brands. Filter replacement should be carried out every 10 thousand km, although a lot depends on the quality of gasoline. One bad fill can be devastating, resulting in a bad fuel filter and clogged injectors, which also leads to unexpected costs.
"Lada" of the tenth family in the "hatchback" body is the VAZ-2112 model. All cars of this family were produced until 2009. The range of engines included four options. Among them, by the way, were two 8-valve. Further we give the characteristics of 16-valve engines, and engines with 8 valves do not deserve attention. The torque graph proves the correctness of these words. So, consider the characteristics of the VAZ-2112 engines with four valves per cylinder.
124 engine under the hood "dvenashki"
In the pistons of the engines of the 124th series, grooves are made for the valves. Simply put, the VAZ-21120 ICE is a plug-in (as a result, and then how lucky), and 21124 is not a plug-in (). Let's evaluate the torque.
Moment of forces, N*m
The most interesting thing here is the VAZ-21120 engine. In terms of “traction on the bottoms”, it is not much inferior to 8-valve.
Formal characteristics
Here are the characteristics of two different motors:
- ICE model: 21120/21124;
- Working volume: 1.488 / 1.596 l;
- Compression ratio: 10.5 / 10.3;
- Power: 93/90 hp;
- Rated power revolutions: 5600/5000 rpm;
- The highest torque: 140/131 N * m;
- Recommended fuel: AI-95/AI-95;
- Ecology: Euro-3/Euro-4 or Euro-3.
The lower the compression ratio, the more “omnivorous” the engine will be in relation to fuel.
Some Conclusions
The steel receiver looks powerful and beautiful
All VAZ-2112 hatchback engines differ in characteristics, and the differences are significant. It seems that the best option would be a 16-valve 1.5-liter engine. But the 21124 (1.6) engine has its advantages:
- Rated power is reached at 5000 rpm, not at 5600;
- Breakage of the timing belt does not lead to bending;
- It is permissible to use 92nd gasoline.
Any 21124 motor can be converted to Euro-4 or meets these standards immediately.
Longitudinal section of the engine mod. 2110
Above are the longitudinal and transverse sections of all used engines on the VAZ-2110. On the VAZ-2110, both the 2110 engine and the 2112 engine (16-valve), created on the basis of the VAZ 211083 engines, can be installed. On some older models, it is possible to install 21083 engines. All these engines run on AI-92 gasoline (16 class on AI-95), according to a four-stroke scheme, in-line, four-cylinder. Engines 2111 and 2112 are injection - with a fuel injection system.
The material of the cylinder block is ductile iron, very hard.
Cooling is made uniform throughout the block, excluding uneven heating. The cooling jacket is open at the top towards the block head. At the bottom of the block there are five crankshaft bearing supports, their covers are bolted. The crankshaft is also made of special ductile iron. The connecting rod bearings are lubricated through oil valves that are drilled into the crankshaft. There are vibration reduction systems - from eight counterweights located on the crankshaft. In front of the crankshaft is an oil pump, timing belt pulley. Behind the crankshaft is a cast iron flywheel.
Forged steel connecting rods with covers on the lower heads. Thin-walled liners are installed in the lower head of the connecting rod, and a steel-bronze sleeve is pressed into the upper head
The pistons have three rings: 2 for compression and 1 oil scraper. The piston material is aluminum alloy. On the bottoms of the pistons there is a recess for the combustion chamber and in the case of the VAZ 2112 engine there are 4 (2 per 2110) recesses for the valves. On a 16-valve engine, the pistons are cooled with oil. On a special fuel rail, 4 nozzles are installed, which are small tubes with spring-loaded balls in them. The oil sump is made of steel, stamped, attached to the bottom of the cylinder block.
On top of the cylinder block is a block head cast from an aluminum alloy. Channels are cast in the lower part of the head, through which the liquid circulates, which cools the combustion chambers. A camshaft is installed at the top of the head (engines mod. 2112 have two camshafts: one for intake valves, the other for exhaust valves). For 8-valve engines, the camshaft rotates in bearings, in the upper part of the block head and two bearing housings, fixed with nuts on studs, screwed into the block head. In a 16-valve engine, the camshafts are mounted in bearings, which are made in the upper part of the block head, and in a common bearing housing. The camshafts are cast iron. To reduce their wear, the working surfaces of the cams and the surfaces under the stuffing box and the eccentric of the fuel pump drive are heat treated. Distribution cams shafts through the pushers actuate the valves. At the engine mod. 2112 hydraulic valve lifters are installed, which do not need to be adjusted, unlike 8-valve engines.
On 8-valve engines (2110, 2111) there are two valves per cylinder: intake and exhaust, on 16-valve engines (2112) there are four valves - 2 intake and 2 exhaust. Guide bushings and valve seats are pressed into the block head.
On 8-valve engines (2110, 2111), two springs are installed on each valve, and on 16-valve engines (2112) - 1. The camshafts are driven by a toothed belt from the crankshaft.
Combined lubrication system: spray and pressure. Under pressure, the main and connecting rod bearings and camshaft bearings are lubricated. The system consists of an oil sump, gear oil pump with oil receiver, full flow oil filter, oil pressure switch and oil valves.
The engine cooling system is passive and active. There is a powerful electric fan that turns on at 115 degrees and turns off at 95.
The power system consists of the following units:
- air filter;
- fuel tank;
- fuel pump;
- fuel line;
- 2110 - carburetor and 2112 - fuel rail with injectors and fuel pressure regulator;
- Various sensors on 2112.
The fuel pump for the 2110 engine is located on the head of the block and is driven by an eccentric on the camshaft through a pusher. 16 cells engines, the fuel pump is electric, immersed in the tank and combined with a fuel level sensor.
The entire electronic system of 8 and 16 valve engines is controlled by a controller (ECU), which also controls the entire engine power system.
The 2111 engine was designed for a front-wheel drive car based on the VAZ 2108, but already a sedan, not a hatchback, so the engine became a hybrid of the 2108 and 2110 internal combustion engines, widely using their parts in its design. It was with modification 2111 that the manufacturer AvtoVAZ began equipping cars with injection engines controlled by an on-board computer.
Motor characteristics 2111
Starting in 1993, the AvtoVAZ manufacturer opened the VAZ-2110 project. A front-wheel drive luxury sedan was being developed, so the carburetor modifications of the 2108, 2110 engines and their variants did not meet the conditions.
Already at the initial stage, the project was divided into two independent works. A simple conversion of the G8 hatchback into a sedan was called the VAZ-21099. The name of the second project remained the same, but work on it was fairly delayed for a number of reasons:
- in 1985, a test sample appeared, it was planned to launch a car with a new engine in a series from 1992;
- the crisis confused plans, the management of the manufacturer's plant put the VAZ-2110 on the conveyor only in 1996;
- in the first cars there was a carburetor internal combustion engine, then a modified 2111 injection type.
The designers managed to make the most of the existing engine elements so that the user of previous VAZ generations would not get confused about which oil and coolant to use. By default, the technical characteristics of the internal combustion engine 2111 are:

The official manual contains information on which oil to pour: 5W30 / 5W40 (winter), 20W30 / 20W40 (summer) and 10W30 / 15W40 (all-weather). The manufacturer indicates engine lubricants from Rosneft, Mobile and Lukoil, a service station specialist usually recommends Mannol, Zic and Valvoline engine oils.
Design features
After many years of refinement, the 2111 motor has the following design nuances:
- engine diagram - electronic control of distributed injection;
- engine block - has holes for fixing attachment brackets;
- cylinders - bored to size 82 mm;
- crankshaft - with a long 71 mm piston stroke, similar to the model 2108, but the counterweights are more powerful to reduce vibrations;
- piston - an oval recess on the bottom so that the valves do not bend, a floating pin fit;
- connecting rod - length 121 mm, the lower head is heavier;
- camshaft - the profile of the cams has been changed, the landing dimensions are the same as in option 2108;
- Timing - copied from 21083, belt drive;
- flywheel - the teeth are wider, the profile has been changed, the diameter of the clutch fit is larger (208 mm), the crown is wider than that of 2110 (27.5 mm);
- starter - gear with 11 teeth;
- belt - 742 mm in the basic version, 1115 mm in the presence of power steering, 1125 mm when the car is equipped with air conditioning;
- ECU - GM, Bosch or January;
- injectors - Siemens VAZ 6393 (nozzle with 4 holes, yellow) with controller January 7.2 or M 7.9.7 or Siemens 6238 (nozzles with 2 holes, gray) with controllers January 5 or MP 7.0.
Thanks to these design solutions, engine performance has been noticeably improved.
ICE modifications
Immediately after the creation of the 2111 motor, the injection was modernized, options appeared:
- 2111-75 - phased injection;
- 2111 -80 - injection in pairs and parallel.
In the first case, the pin on the end of the camshaft allows the DPRV sensor to track the position of the valves (closed / open). A mounting hole for the crankshaft position sensor has been added to the oil pump. For the second option, a 2110 camshaft is used.
Pros and cons
The above description of the parameters exceeds the characteristics of the entire line of internal combustion engines existing at that time, produced by AvtoVAZ. However, "inherited" from motors 21083 and 2110, the 2111 engine received disadvantages:
- broken studs in the "silencer-exhaust manifold" mount;
- breakdown of the fuel submersible pump;
- leaky valve cover gasket;
- low resource of elements of the cooling system;
- periodic adjustment of the valves.
The advantages are low oil and fuel consumption, possible do-it-yourself forcing, but only due to the refinement of existing units.
What cars was used?
The 2111 engine was installed on the following models of front-wheel drive VAZ cars:
- 2108 - three-door hatchback;
- 21083 - three-door hatchback;
- 2109 - five-door hatchback;
- 21093 - five-door hatchback;
- 21099 - sedan;
- 2113 - three-door hatchback;
- 2114 - five-door hatchback;
- 2115 - sedan;
- 2110 - sedan;
- 2111 - five-door station wagon;
- 2112 - five-door hatchback.
On the "eights" and "nines" the motor was installed after 1987, respectively.
Maintenance procedure
The upgraded ICE device changed the standard maintenance regulations developed for previously released engines, so the 2111 engine is serviced as follows:
| maintenance object | Time, year / mileage, thousand km (which comes first) |
| timing belt | replacement after 100,000 km |
| battery | 1 /20 |
| Valve clearance | 2 /20 |
| crankcase ventilation | 2 /20 |
| Belts that power attachments | 2 /20 |
| Fuel line and tank cap | 2 /40 |
| Motor oil | 1 /10 |
| Oil filter | 1 /10 |
| Air filter | 1 – 2 /40 |
| Fuel filter | 4 /40 |
| Heating/cooling fittings and hoses | 2 /40 |
| Coolant liquid | 2 /40 |
| oxygen sensor | 100 |
| Spark plug | 1 – 2 /20 |
| Exhaust manifold | 1 |
If the owner tunes the internal combustion engine to increase power, the frequency of replacement and diagnostics indicated in the table should be reduced by 30 - 50%.
Typical malfunctions
After many years of operating experience, it has been noticed that the 2111 engine is prone to the following breakdowns:
The exhaust system of the engine is not finished, so the exhaust manifold cracks and its fasteners break. A feature of the timing is the low resource of the valve cover gasket.
ICE tuning
By default, the engine uses the maximum diameter of the cylinders, so boring them even more will not work or will be too expensive. The following types of tuning are used:
- FNS filter - zero resistance can “revive” the motor;
- throttle 54 - a damper of a larger diameter must be mounted in tandem with the Federal Tax Service;
- straight-through exhaust system - spider circuit 4/2/1 and a resonator with banks;
- sports camshaft - gas distribution modes change.
Thus, the ICE 2111 is an order of magnitude superior to carburetor modifications, does not bend the valve, is economical in operation, so it was produced for a long time and a lot to complete the entire line of front-wheel drive cars produced at that time. Thanks to several repair sizes of the piston and cylinder, it is possible to make a major overhaul on your own.
If you have any questions - leave them in the comments below the article. We or our visitors will be happy to answer them.
The VAZ 2111 eight-valve injection engine is a logical continuation of the VAZ engine line. It replaced models 21083 and 2110. This unit was installed on all Lada Samara cars (from 2108 to 2115) and the tenth generation Lada (2110, 2111, 2112). It is considered the first modified injection device on domestic cars. We will describe the main technical parameters of the engine: the connecting rod and piston group, the cylinder block, the principle of fuel supply. We will also consider the cooling and lubrication systems of the engine.
General structure of the motor 2111
The serial number of the VAZ 2111 engine is 100026080. The following technical characteristics of the unit are stated in the operation and repair manual.
Fuel supply system - injector with distributed injection. The VAZ engine control system is electronic using sensors. The motor runs in four strokes (intake, compression, power stroke, exhaust). When intake occurs in cylinders 1 and 4, 2 and 3 stand still. When the piston in the first and fourth cylinder rises and compresses the combustible mixture, air and fuel are admitted to the other two cylinders. Gasoline is injected into the cylinders using injectors.
The engine, together with the gearbox and clutch, form a single power unit. The fastening of this single block in the engine compartment is carried out by means of three rubber-metal supports. When viewed from the driver's seat, the crankshaft, camshaft and coolant pump drives are located to the right of the cylinder block. Connection - by means of a toothed belt (111 teeth). With the generator drive, which is also on the right, the internal combustion engine is connected by a V-ribbed belt.
On the left side there is a starter, an antifreeze temperature sensor, a thermostat. From the front, candles are screwed into the combustion chamber, on which high-voltage wires are put on. Also in the front is a knock sensor, a dipstick to check the oil level, a crankcase ventilation hose and the main source of energy is a generator. A receiver, a fuel rail with injectors, intake and exhaust manifolds, an oil filter and an oil pressure sensor are attached to the rear.
The declared resource of the engine 2111 is 150,000 km. The 16-valve injector has the same wear life.
The crank mechanism of the engine 2111
The cylinder block is made of cast iron, similar to model 21083. The factory diameter of the cylinder is 82 mm, when boring it can increase by 0.4 or 0.8 mm. Cylinders are divided into classes. Depending on the diameter, the model A,5,C,2,E is distinguished. Wear is allowed - no more than 0.15 mm.
Five main bearings with caps are attached to the bottom of the block. The middle support has nests for supporting half rings. They are designed to prevent the crankshaft from deviating from its axis. The crankshaft play must not exceed 0.26 mm. If the indicator is exceeded, the half rings are replaced.
Bearing shells (main and connecting rod) - thin-walled steel-aluminum alloy. The crankshaft material is high-strength cast iron. There are 5 main and 4 connecting rod journals on the shaft. Eight counterweights are cast on the shaft.
At the front end of the crankshaft is the camshaft drive pulley. The alternator drive pulley is attached to it with a pin. In the gap between the parts of the pulley there is an elastic element that softens the vibrations of the crankshaft. There are only 60 teeth on the pulley, 2 of them are skipped to determine the top dead center (TDC) of the piston.
The other end of the shaft is attached to the flywheel. The flywheel is also cast iron. It is installed in such a way that the conical hole located near it stands exactly opposite the connecting rod neck of the fourth cylinder. This is necessary to set the TDC when the VAZ 2111 engine is being assembled.
Each connecting rod is made of steel, has an I-section. The upper head of the connecting rod is equipped with a steel-bronze bushing. There are different classes of 2111 connecting rods depending on the inside diameter of this bushing and the mass of the connecting rod. Diameter pitch - 0.004 mm. One engine must have connecting rods of the same marking.
This engine uses aluminum alloy pistons. The upper part is machined, has grooves for rings. In the groove of the oil scraper ring there is a hole for dumping the removed oil layer into the pin. The hole for the finger in the piston itself is offset by 1 mm from the axis, therefore, when replacing, we look at the arrow that is stamped on the bottom. When looking for parts for repair, it is important to know that the piston bottom of the VAZ 2111 injector 8 valves is equipped with an oval recess. Not to be confused with a piston for a 16 valve engine. Its bottom has a flat shape and 4 notches for valves.
Pistons, depending on the diameter, are also divided into classes: A, B, C, D, E. When replacing, it is necessary to pay attention to the marking so that the piston matches the cylinder. The gap between new parts should not exceed 0.045 mm. A new piston can only be installed in a new cylinder or a bored one. The maximum difference in mass between the pistons is 5 g.
The compression of the VAZ 2111 engine should not fall below 10 atmospheres.
