Ignition on 16 valve motors 2112. General information about cars

Became another constructive breakthrough for AvtoVAZ. Finally, the 4-cylinder power units of the domestic manufacturer received modern system Tsp with two camshafts and 4 valves per cylinder. A total of two main 16-valve injectors installed on the top ten. This is a 1.5 liter engine model 2112 and 21124 1.6 liters.

The most interesting thing is that an injection motor of 1.5 liters is more powerful, its more voluminous fellow. The VAZ-2112 engine develops 93.5 horsepower, while VAZ-21124 is only 89 hp Compression in 1.5 liter 16-valve is slightly higher. However, Motor 2112 has one drawback. In the event of a belt cliff, the valve is bent, which leads to a very expensive repair. In the engine VAZ-21124, this problem was solved by making special recesses under the valve in the bottom, it certainly reduces compression, but the valve is not bent when the timing belt is broken.

Characteristics of VAZ 2110 Injector 16 valves

In technical plan, 16-valve engines VAZ 2110 are almost the same, however, due to the difference in working volumes there are some differences. So the engine 21124 has increased piston stroke, therefore the height of the cast-iron cylinder block is more than several millimeters. The diameter of the cylinders of both engines is the same - 82 mm. Further more detailed specifications Injector engines "Dozens" with 16-valves.

With all the pluses of the 16-valve gasoline engine VAZ-2110, this power unit is technologically more difficult than its 8-valve fellows. The head of the cylinder block is made of aluminum alloy and has quite impressive sizes. Banal valve adjustment takes quite a long time, and already capital repairs GBC 16-valve engine is a fairly labor cost.

Most often almost all 16-valve owners injector motors "Dozens" are faced with the replacement of the timing belt, which also requires increased attention. After all, the camshaft plots are already two, plus the groove roller roller is added. When installing a new belt, it is necessary to combine three tags, on the camshaft pulleys and the crankshaft pulley. In the theory, it looks something like that, as in the image further.

This is detailed scheme of the GDM 16-valve injector VAZ-2110. And so it looks like everything on the real photograph of the assigned timing belt.

GDM device VAZ 2110 Injector 16 valves In principle, it differs little from DOHC engine devices. So if you have the experience of replacing the belt on the "top ten", then problems with this operation on other cars with the same engine will not cause problems. It is worth recalling again that incorrect installation belt on a 16-valve 1.5 liter motor can lead to cut valves. So be sure to check that all the labels are clearly coincided. Also, the belt should be quite stretched, otherwise the timing belt may happen, which will cause inevitable problems.

It is used on VAZ 2110 8 Valves Injector to adjust the fuel to the system. The slightest deviations in its work negatively reflect on the operation of the engine " iron horse" In the late 70s of the past century injector Engine VAZ 2112 became the result of perennial searches for the economically reasonable form. The used technical solution makes the motors safer - with a possible cliff, the pistons will not hit the valves.

Injector - a device that makes mixing air and fuel streams in a ratio of 14 to 1. The more accurately happens, the higher the engine power vehicle. The challenges of the "iron horse" depend on the ratio of the atmospheric pressure of the surrounding air and vacuum. Optimize fuel injection helps sensors controlling the parameters of the VAZ 2112 and 2110 motor parameters.

On the intake manifold Located ramp, where the mixture of air and fuel is localized. Pumping out fuel tank produces fuel pumpoperating on an electrical drive. In perfect condition, the VAZ 2112 engine is characterized by tightness, providing an appropriate pressure level in the system. Second important element Systems - the throttle of the throttle.

Under normal conditions, said item is responsible for the amount of gasoline supplied to the VAZ engine. The fuel supply system includes:

• gasoline pump, which is driven by the engine rotor;
• filter;
• tubes;
• ramp in the motor;
• flexible nozzles;
• throttle assembly;
• sensor schemes (located between the filter and choke).

Understand what exactly the engine VAZ 2110 and later model with injector system Injection can only be inspected in detail. From a constructive point of view, the new and flock of the "heart" of the car does not have differences. Missets are manifested at the level of small details. For example, the VAZ 2112 or 2110 engine has exactly 8 valves. Do not miss the thermostat from sight.

Injector motor is characterized by the presence of a large number of parts often fail. It is during preventive inspections in obligatory The thermostat is checked with an injection injector fuel injection. If the regular inspection of the motor is not carried out, the probability of long downtime increases due to breakage.

Diagnosing technical faults

The widespread illusion of the VAZ 2112 engine is a failure of one of the numerous sensors. The first in the list of potential targets is the controller of the mass flow of air. You can easily determine the breakdown in the motor, but you can. ATTENTION must be reversed on the revolutions of the vehicle engine and the level of consumption of fuel. If the indicators exceed the indicated in the instructions for technical exploitation Values \u200b\u200bshould be diagnosed. It is not worth a honey with this, otherwise the VAZ 2112 16 valves risks for a long time to become uncommon from the garage. In second place is a failure of a flexible pipe.

In working condition, its length is sufficient for the formation of the quantity of the quantity fuel mixes. As soon as the tightness is disturbed, the motor breakdown occurs. The main consequences include:

• increased flow rate of fuel;
• reduction of power;
• reduction of overclocking dynamics;
• the appearance in the motor of the sediment layer of the inventive substances.

The relevance of the last paragraph increases as deterioration. technical Conditions operation. Often riding in a big city negatively affects the operation of the motor filter. Chemical elements present in the air of megalopolis lead to the inability of said devices to feed clean air into the mixing chamber. As a result, the repair of the VAZ engine becomes inevitable.

Restoring the health of the car

The attention of the car owner is the key to the health of the "iron horse". The lack of the motor reaction to turn the ignition key in the system indicates problems, first of all, with an injector. The initial inspection begins with visual examination. VAZ 2110 Injector 16 valves should not have visual damage or chipping. For inspection using tools, the motor lid of the engine is taken carefully.

Immediately after removing the spool, check the correctness of the engine. In the normal condition, the VAZ motors are characterized by the indicators of the pressure gauge ranging from 2.8 to 3.2 atm. If the actual indicator is below the specified value, the motor needs an in-depth check. It is probability that the cause of the fault lies in a flexible nozzle.

In the normal state of the VAZ 2110 injector 8 valves is completely sealed. If the inspection in the conditions of the garage or the service station did not help reveal the place of depressurization, the broken motor needs to replace the failed aggregate. More difficult if the testimony of the pressure gauge is higher than the specified values. In this case, the engine 16 valve or its analogue needs to replace the starter. The scheme of action is as follows:

• remove the traction relay;
• unscrew 2 bolts key to 13;
• remove one nut; If motor for a long time professionally did not do, the specified procedure is somewhat difficult; Loosen the thread on the thread will help increased physical effort; Nevertheless, it is not necessary to try too hard, otherwise 16 or 8 valve engine fails;
• dismantle the starter housing;
• check brushes - the most vulnerable element; 8 or 16 Valve engine often fails as a result of the integrity of the mentioned brushes. The revealed minimum damage to them is an immediate replacement. Cheer with the specified procedure is not worth it.

Significant gearbox becomes much less racket. Standard 8 valves Injector is characterized by increased sensitivity to external pollutants.

Careful gear cleaner significantly reduces the likelihood of problems with the engine.

Rarely encountered breakdowns

If all of the above has not brought the desired effect, you need to look for the reason. With a high probability, it can be argued that the VAZ 2110 injector 8 of the valves has become a victim of the failure in the gear gear. With significant loads, they wear out much faster.

With regular technical Services The device of the VAZ 2110 motor is properly, but if such inspections are irregular, with the VAZ 2110 16 valves occur. If the inspection did not help eliminate problems with car motorIn manual mode, all parts of the gearbox are checked.

It is designed in such a way that with a slight breakage of just one piece, all the device ceases to function. Vaz 2110 16 valves will help an in-depth inspection. With the VAZ motors, various breakdowns happen, but it is possible to determine and eliminate those in 2-3 hours. If, after the specified period of the VAZ 2112, the device did not reveal the secret breakdown, it is easier to replace the gearbox.

It should be much less likely to blame the incorrect tuning of the Iron Horse. When installed additional elementsnot provided for by the initial equipment on the motors, a disruption of the system tightness is allowed. In second place is an environmental problem. The increased volume of passed air carries more dust particles, dirt and chemical elements littering the system.

Injection engine system improved running performance model Row VAZ. In this case, the driver is forced to pay more attention technical state "Iron horse", which will reduce the probability of downtime due to breakdowns.

The front-wheel drive vehicles of the VAZ of the tenth family (the VAZ-2110 sedan, the VAZ-2111 wagon and the WAZ-2112 hatchback) were completed with various engines. Among them were carburetor and injection, 8 and 16-valve.

The ignition also used two types: from the central distribution module or using independent ignition coils. The reader is offered one of these motors: Engine VAZ 2112, the beginning of the release of 1997

Passport details

Initially, the 12th was produced in 2 versions: 21120 and 21124. Characteristics of the 16-valve engine VAZ 2112 of these modifications are given in the following table.

From the table it follows that the technical characteristics of the two versions are pretty close, with the exception of a higher torque in the 120th motor.

Powerbound

The VAZ 2112 engine was created not from pure sheet. Its structural scheme with a 16-valve gas distribution mechanism (timing) repeats model 2110, and the cylinder block (BC) is a copy of the "eight" (21083). This can be verified by comparing their geometrical parameters: the diameter of the boring and the center distances.

True, the blocks are not interchangeable, since they are distinguished by the diameter of the screws of the cylinder head mount (GBC). Unlike parts 21083 and 2110, BC has additional oil channels in the indigenous supports for supplying oil to lubricating nozzles. Through these devices, an additional lubricant of the lower part of the cylinder surfaces is carried out, as well as the cooling of the bottom of the pistons.

Now a little about what the 120th and 124th motors differ among themselves. VAZ 21120 contains BC 2112 with a height of 194.8 mm, and 21124 - BC 11193. The high-dimensional parameter of the latter is 197.1 mm (the so-called "high" block). The 124th crankshaft is longer compared to the 12th. Motor 2112 knee has a size of 35.5 mm (stroke 71), and at 21124 - 37.8 mm (75.6 stroke). As a result, the working volume of the 124th version is 1.6 liters, against 1.5 - in the 120th.

Differ among themselves and pistons. On those and others there are cekets to ensure the exit of the valve plate. However, on the 120th engine, their depth is deceptive. It is designed only for the staffing of the timing, and in the case of the cliff of the gear belt "Meeting" of valves with pistons becomes imminent. In the 124th drive, everything is in order, the elimination of the incident will require only the replacement of the belt without disassembling power aggregate.

The replacement of the pistons at the motor 21120 124-mi will avoid the troubles concomitant belt cliff. True, the power of the engine VAZ 2112 will be slightly smaller.

Other differences

The engines are also distinguished by the design of the "inhale". The 120th inlet consists of two aluminum parts: collector ("horns") and receiver interconnected by rubber corrugations. Aggregate 21124 "Decorates" intake system, made of plastic and consisting of a single part.

The ignition system is located differently. VAZ 2112 is equipped with a ignition distributor module, and individual coils are installed for each cylinder for each cylinder. Due to the differences in the intake and ignition systems, valve covers are different.

The 1.6-liter unit has some more differences from the fellow: the pressure regulator is transferred from the fuel ramp to the pump, the catalyst is located directly at the GBC, there are 2 oxygen sensors (Euro-3) instead of one (Euro-2) in 1.5 liter. Separate design of the GHM housing simplifies the replacement of the toothed belt.

Often asked: where is the factory engine number on the VAZ 2112? Indeed, a room located under the air filter is quite difficult to detect. It is located in the rear end of the BC, under the thermostat case. To find the right numbers, you need to free the mount air filter And somewhat reject him aside.

Possible malfunctions

Motor unit of the 12th family when proper care It works safely, because the basic design was created in collaboration with the German company Porsche, which is an authority in the field of engines. The only "jammer" is the use of belt gear. D.

ea and not even in it, but in the fact that the vasers persistently do not want to take into account the Russian realities. The use of a toothed belt requires high-quality spare parts, which we, unfortunately, have to dream of. Yes, and the regulated service is not all carried out, relying on the well-known Russian "Avos."

After all, they did in the 124th engine the normal cekkops on the heads of the pistons, and there is no problem, while the engine 2112, like some other VAZ engines suffer in congenital illness called - "Gnet of the valve". The remaining malfunctions are typical for many DVS, including VAZ engines:

• Engine 2112 starts. Malfunction should be signed in the distribution module, high voltage wires, Ignition Candle.
• Unstable work on idling (XX). In this case, the control device is checked, the crankshaft position sensors and the throttle plate. It is necessary to clean the latter. If the search did not give the result, most likely, DMRV refused.
• It stalls the drive on the XX or in motion (during transmission). This may be a consequence of pollution of the throttle mechanism, its sensor (DPDZ) or RCX.
• When starting, the motor "does not grab". If not a starter or battery is to blame, the fault should be signed in the ignition system or power.
• Picked hydrocomathers or, which is much more dangerous, indigenous or skeeping inserts. This usually leads a decrease in the oil pressure in the engine.
• Motor aggregate slowly warms. It is necessary to check the condition of the coolant and the thermostat action.
• The motor is bad, the workflow is accompanied by vibrations. It is advisable to diagnose the power unit.
• Insufficient oil pressure - causes can be several. One of them - unreasonable replacement Oils in the VAZ engine. With long-term operation, an oil pump can fail.

If the indicator is on - there is no oil pressure, the movement should be stopped before finding out the fault, if necessary, resort to the services of the tow truck.

Repair and maintenance of the power unit

As an example, a specific case is given. repair work. The repair of the VAZ 2112 engine was required in several testimony: it is necessary to constantly add toosol, blinks the lubricant control indicator, click hydrocomathers. Pre-conducted a compression measurement, which showed the difference in cylinders to two atmospheres.

During the disassembly, the causes of the malfunction were determined:

• the skeleton of the GBC laying, as a result of which Tosol went into one of the cylinders;
• corrosion of the railway plane of the GBC;
• wear of the liners of the root crankshaft;
• wear of the guide of exhaust valves;
• sintering the internals of the catcollector.

Description of motor restoration procedures:

1. milling of the head plane and the block plane of the block;
2. remensant of guide sleeves of exhaust valve;
3. mechanical processing (without wipes) valve saddles;

Installing new details:

• pistons of the dimensional group C (instead of native B);
• piston rings;
• crankshaft liners and stubborn semirings;
• glazes and gaskets;
• cooling pump;
• valve stem seals;
• metal gLP gasket from priors;
• toothed belt complete with tensioner roller POWER GRIP;
• ina hydrotheraplers;
• candles ngk;
• "Spider" 4-1 of stainless steel;

Often asked: what oil pouring into the VAZ 2112? In the described case, after the assembly was flooded motor oil Lukoil Luxury 10W40.

Replacing the oil on VAZ 2112 requires 3.3 liters of fluid, and with a concomitant replacement of the filter - 3.4, although the total volume of the lubrication system is 3.6 liters.

Tuning opportunities

Lovers of "catch up" are interested in the question: how much horse power Can additionally get a tuning engine? The engine tuning of the brand 2112 is performed in different ways:

• replacing cam shafts on tuning (STI-1, STI-2, STI-3.1, Clauses 8.9) Along with the installation of lightweight SPGs, increased throttle valves and "pants" 4-2-1 will force the 120th engine to 120 liters. from;
• if you modify the GBC and put wide-view camshafts, the increase will be 130-140 liters. from;
• installation of the crankshaft with a long crank (37.8 mm), the improvement of the combustion chamber in the GBC and the use of T-shaped valves will raise power up to 150 liters. from.

The fans of the "classic" zhiguli install the VAZ 2112 engine on the rear-wheel drive machines: VAZ-2105, -2107. So that the unit can accommodate under the hood, even part of the engine compartment partition is cut out.

Generation of 12 engines turned out to be "long-playing." In addition to the above-described brands, others were also developed: VAZ-21126, -127, -129. Them and today put on cars Lada PRIORA, LADA KALINA, LADA GRANTA.

The efficiently functioning cooling system on the VAZ 2110 allows the engine to work in optimal mode, nor overload or overheat. But if there is an increase in the temperature of the motor, then something happened to the cooling system (CO). The task of the car owner is to do everything possible to reduce heating.

It is noteworthy that underheating and overheating is dangerous for the motor equally. In order to understand the features of the repair of CO, it should be found in the principle of its work.

How to work so

1. On 8 valve injector VAZ 2110, the cooling system operates due to the coolant, forcibly circulating on it. When the motor is heated, an excessive pressure occurs, which exits the means of the exhaust valve.
2. For 16 valve injector VAZ. 2110 The cooling system has an optimal operating temperature in the range of 90-95 degrees Celsius. A valve is triggered when the pressure occurs with indicators from 1.2 to 1.4 kgf / cm2.
3. When overpressure comes out, the engine returns to normal temperature, the inlet valve is turned on. This is where the cycle cycle occurs.
4. If the pressure balance is violated, overheating occurs, the consequences of which there can be different sodes of breakage, including the need to fully replace the power unit.
5. Due to the thermostat and the electric fan, the VAZ 2110 supports the necessary constant working temperature. The cylinder head is a sensor that transmits information about the current coolant temperature to the control unit.
6. From the temperature sensor, the coolant is a command to a cooling system that begins to work in order to reduce the heating of the engine.
7. In the presence of electronic injection in the design of the car, it also has a special sensor that sends a message to the electronic unit Management on overheating of the power unit.
8. With the pump, the coolant distributed by the thermostat is supplied.
9. When the engine is turned on, it needs to warm up to temperature performance. For this, the thermostat sends a cooling fluid over a small contour, not including circulation through the radiator. Small contour includes:
   1. Heater to warm out the cabin;
   2. The heating unit of the carburetor (naturally, only on carburetor Vaz 2110);
   3. Heated block of throttle assembly;
   4. Intake manifold.
10. When the engine heats up to about 90 degrees Celsius, the thermostat sends a part of the coolant to the radiator. When the engine overheating sensor is triggered, the entire cooling fluid circulates by a large contour.

Characteristic malfunctions

If the cooling system is "dozens" begins to function not as it should be, it says about the appearance of faults.

It is possible to determine them by characteristic features.

• Disappears coolant from the system.
• The engine requires a lot of time to warm up, or it is badly warming up. If strong frosts are characterized for your region, and weak warming is observed in winter, the reason lies, most likely in the climate. Therefore we advise warming up motor compartment.
• Motor detonation occurs. If there is a similar situation, the cooling system has been faulty for a long time, and you still continued to exploit the car.
• The sensor on the instrument panel has reached an extreme red zone.
• Torque decreases. Such a phenomenon is characteristic of the situation when the engine overheated and there is a skip on the head laying.

How to fix problems

Now let's talk about eliminating these faults according to the voiced list.

1. The cooling fluid cannot disappear on the wave of the magic stick, it does not evaporate under the action of temperature. Therefore, it is necessary to check all the nozzles, hoses, clamps, radiator and other components. Somewhere necessarily there is damage causeing leakage.
2. If in winter you have to stand in place long, waiting for the engine warming, try to insulate the engine compartment. There are many ways to do this - from the classic "Tulupa" for the engine, before applying simple cards in front of the radiator in the winter or the use of special insulation. Watch sure that your insulation does not hurt the generator belt.
3. When detonation, we can only sympathize with the car, because his owner completely ignored all the signals of the machine that the CO is in a faulty state. If the simplest repairs will give a positive result, consider what you are big lucky. If not, then the engine repair does not avoid. And this is completely different amounts of money.
4. When the arrow of the sensor was in the Red Zone, immediately take appropriate measures. Mock the engine so that excessive overheating does not lead to even more sad consequences. Raise the hood, check the presence of fluid in the tank. Just do not open it, there is very hot. With a timely reaction, boiling and whistle from under the hood can be avoided. But it is better not to go to your progress. Call the tow truck.
5. Situations when motor head gaskets are not rare. But we do not want to face anyone. Such a breakdown says that you must necessarily begin to fully repair the engine. Alone or on the car service - decide for yourself.

Prevention measures

A huge part of the breakdown can be avoided if appropriate to refer to own car. Yes, no one excludes unforeseen situationsHowever, simple prevention measures must necessarily become a norm of handling the machine:

• Check the cooling fluid level permanently in the tank, plot if necessary;
• For your VAZ 2110, do not suck on high-quality cooling fluid;
• Do not use simple water as a cooler, since it has a smaller boiling point, contributes to the formation of scale and corrosion inside the cooling system;
• Always look at the testimony of the temperature sensor, located in the cabin. Avoid situations where the arrow passes the red border.

Obviously, it is the most important node in open space, on the efficiency of which the state depends, engine performance and not only. Therefore, it is extremely important to take care of the cooling system, monitor its condition, to take a timely actions to eliminate the faults.

VAZ-2112 became the last in the line of the 10th model. This is a modern and dynamic machine, which has significantly improved operational, as well as external indicators. It is worth saying that this is the most-selling car. Buyers are attracted low pricesExcellent maintainability, as well as high practicality.

History of the model

The tenth family of front-wheel drive models of the Volzhsky Plant began in 1995, with a model 2110 with a body of a sedan. Then in 1998, the plant was launched at the factory - 2111. In the 99th plant began to produce hatchbacks.

In the first years of release for 2110, a 1.5-liter sixteenthlymost engine was used. At that time it was the maximum of the factory capabilities.

In 2000, the plant presented new version Hatchback - VAZ-2112, 16 valves. Compared to an ordinary eight-shield version, the car had more power and dynamism. The model immediately conquered car enthusiasts, her appearance was sports.

Package

The car was produced and offered in the luxury and norm. "Norma" from the luxury version is distinguished by the fact that there was no route computer, fog lights, set alloy wheels, Headlight cleaning systems.

The "norm" is equipped with electrical windows for all four windows, a central lock, drive a remote opening of the trunk, steering column with the possibility of adjusting height, immobilizer.

What is the most interesting, nor in one of the packages (how expensive they would be) no air conditioning. According to today's standards, this is quite a big minus, because of which drivers are increasingly looking towards used foreign cars.

Appearance and body body

As for the dimensions, the VAZ-2112 (16 valves) decreased in a length of 93 mm. This change occurred in the rear sink area. But at the same time the size of the wheelbase was not transformed. The body length amounted to 4170 mm. And the height of 1676 mm and the width of 1430 mm remained traditional for the "tenth" family. The line of the vertex on this body is very smoothly turning into a fairly short rear Sve and a large anti-car. This design allowed developers to make a car more manageable.

If you compare this hatchback with more classic VAZ models, it is worth noting that the "twelve" has the best aerodynamic characteristics and modern appearance. The model is very popular with tuning lovers.

Fully galvanized Body "Dozens", which became very popular at one time, still undergoes corrosion. Many owners of new cars did not consider it necessary to perform anti-corrosion processing. The bottom very quickly rust to the holes.

Interior and Salon

In the interior of the VAZ-2112 (16 valves) - all the best from two brothers. The very connected here best features Salon station wagon. Back chairs are divided into two parts. Each of them can be folded. So significantly increases the volume of the trunk. And this is the only dignity. In the cabin everything is more modest than in any foreign cars of the same classes and the same years.

The owners say there is little light both in the cabin and on dashboard. All the panels seem to be well assembled, but it's still somewhere sorry. Central tunnel next to manual brake Equipped with buttons for power windows - it is believed that it is not very convenient to use this. For passengers in the back there are no such options - in basic configuration Even mechanical handles are not provided.

Another minus, according to the owners of the VAZ-2112 car (16 valves), is a complete absence of at least some sound insulation. When moving with the included music, it is clearly audible how the engine and the hydraulic can work.

Big trouble is an incredibly close pedal block.

From the edge of the brake to the console - just over 10 cm. Many complain about this very narrow opening. In order to work with a gas pedal, you have to retrieve the leg of sideways. And if you do not turn it out, then when clamping the pedal accelerator, the leg clings the brake. In 2110, everything is in order. Maybe the reason here is that the slackening pad is made more convex? Maybe.

And the front armchairs are successful. They are additionally equipped with side support. But here everything is not so unequivocal. Many complain about uncomfortable adjustments. But large people are perfectly placed in the salon and in the driver's seat - this is a dignity, as there are few places.

Another positive feature is the small height of the trunk shelf. It is worth opening the fifth door, and nothing prevents loading.

In car good visibility. But the mirror in the cabin is not too comfortable because of the large racks and slope of the glass. Rear passengers also celebrate excellent characteristics in this plan. But little space above the heads behind.

Chassis and steering

The main claim to the chassis - excessive softness. This is all due to the revised suspension system. But many drivers lack feedback. And while the car is perfectly controlled. Rotate a bit steering wheelYou will immediately feel the result. On the inertia, this hatchback is many times greater than the sedan, and the wagon. But rotating the steering wheel at low speeds is quite difficult. Wines in this completely falls on the hydraulicel. It reduces the effort, but the machine is not made from this more obedient.

Riding characteristics are quite confident. On ice, the car is managed. ABS Here, of course, no. Brakes with a vacuum amplifier and discs - in front, and behind the drum. Brake - and good.

Engine VAZ-2112 (16 valves)

As a power unit, engineers used something new. The unit was created not again, and on the basis it retained all the geometric characteristics of the 83rd, but at the same time it is completely different from it both in terms of power and other characteristics. In developing it was attended by eminent car brands. The engine is highly economy. Among the minuses - a weak torque on low revolutions. Also owners write in reviews of a weak belt drive if belt belt Timing.

VAZ-2112 (16 valves) has a 1.5 liter engine. The power he can issue is 93 liters. from. The torque is 133 nm at 3300 about. As for environmental standards, the motor is developed under the "Euro-3". On each cylinder operates 2 valves. One - on the inlet, the second is to release.

Design features

The four-stroke engine of the VAZ-2112 car (injector 16 valves) is distinguished by inline the location of the cylinder and Crankshaft In this unit common for two distributional shafts. Fluid-based cooling system, closed type. Circulation of coolant forced type. Combined lubrication system.

Cylinder block, connecting rods, pistons

The VAZ-2112 engine (16 valves) is equipped with a block cast from high strength cast iron. At first glance, it seems that it is completely similar to the model 21083. But this is not the case. The main difference is less than 10 mm diameter of the head bolts. Other tides for injection system sensors and other honing technology.

Runners are made of steel by forging. They are distinguished by a foreign cross section. The same connecting rods can be found at 2110.
