During the formation of the automotive industry, 4-cylinder engines were among the most popular. And today they are the most common. It happens that, due to a number of reasons, one of the cylinders “turns off”, and the unit works on the remaining three. It happens that the VAZ-2114 engine is troiting an injector (8 valves). What are the causes of this phenomenon and what to do about it? Let's try to figure it out.
Engine Specifications
For cars of this model, an 8-valve engine with an index of 2111 was developed. If we compare this unit with others, then there are serious differences. This is electronic control and distributed fuel injection. The ECU fully takes into account all the basic data that is required for efficient operation. The motor is quite hardy, powerful, economical.
Power is 78 horses. Volume - 1.5 liters.
There are two valves for each of the four cylinders. They have a diameter of 81 mm. The design features of this unit allow you to increase the power characteristics up to 120 hp. With. There is also a modified unit with a volume of 1.6 liters and a capacity of 80 hp. With.
Owners are very happy with these motors. They are completely justified. However, it happens that the engine troit on the go, and other malfunctions are also observed. In most cases, these can be easily repaired.
How to understand that the motor is zatroil?
It is very difficult to confuse this with something else. Even inexperienced motorists can clearly hear this sound. The smooth running of the engine turns into intermittent terrible sounds. It is difficult to describe, but instead of the usual hiss, it will “boom” from the muffler.
Consequences
If the VAZ-2114 engine is troited by an injector (8 valves), then the internal combustion engine immediately loses power. After all, on three cylinders everything is different. Another typical sign for the VAZ line is vibrations, as well as trembling from the engine compartment. Another symptom of the "disease" is increased fuel consumption and a distinct, rich smell of gasoline from and in gases. And that's not it. It is important to respond to the signals that appear in time, otherwise the car will need serious repairs.
When one cylinder is not functioning, the fuel mixture in it does not burn, but simply accumulates.
Then it is diluted with oil and sent to the crankcase. The more fuel that gets there, the thinner the oil will be. It will quickly lose its lubricating properties. As a result, there is increased wear of the cylinder-piston group, rings and other parts. After some time, the engine will need a major overhaul (VAZ-2114 is the model in question).
Causes
There are a lot of them. There are even such nuances where even real professionals may not immediately identify the problem. However, here are the statistics of the most common causes.
Tripping can occur due to a broken candle. Also, this phenomenon is observed with a broken high-voltage wire, failure of the ignition coil, a faulty ECU unit. Another possible reason is in the intake manifold, exhaust valve burnout. With a broken cylinder head gasket, this problem also appears. This effect is also caused by broken compression rings, piston burnout. Naturally, these are far from all the reasons why the VAZ-2114 engine is troiting an injector (8 valves).
Making a self-diagnosis
Now that you know the causes, let's take a look at how the diagnosis is made. You need to start with the simplest. Let it be an idle cylinder.
So, the first step is to start the engine and open the hood.
Then listen to the engine running and memorize that sound. Now, one by one, take out the high-voltage ones; they will not receive voltage, and the cylinders will stop working. Listen. Has the sound changed? If not, then your problem is a bad cylinder.
Checking candles
It is important to find out if the spark enters the cylinders. To do this, you will need to unscrew the candle from the idle cylinder, inspect its electrode. If you see soot or soot, then such an element should be replaced. You can clean the candle, but this is not forever, but only temporarily solves the problem.
Now check the spark plug for spark. Connect a high-voltage wire to it and place it with the metal part against the motor housing. In this case, lay it so that the electrode does not touch the body. Next, invite an assistant. His task is to rotate the starter, and yours is to monitor the candle. If sparks come out when the starter is running, then you may have a problem with the wires. It is also due to a non-working coil, ECU or crankshaft position sensor. There is probably a shift in the timing belt, which can be the cause of tripping on the go.
Troit in wet weather
Yes, and this is not a joke. Many owners of VAZ families of cars note that “iron horses” that have been recently washed or just on a damp day begin to triple.
Among the common causes is liquid that has entered the candle wells.
As a result, the candle stops sparking, which means that the cylinder cannot work correctly. But that's not all.
So, various sensors could fail due to exposure to an aggressive environment. Also, when washing with high-pressure cleaners, various vulnerable parts could be damaged.
As for the environmental conditions, in wet weather the engine troit after a long period of inactivity. The engine does not start immediately, but from the fifth or sixth time. The operation of the motor is uneven and unstable until fully warmed up. Visual inspection often does not give results. The operation of the motor becomes normal after a while until it cools down completely or until the next rain. The reason here is partly the same as after the car wash.
Dampness, or rather, condensate accumulates under the distributor housing. There is an easy way to diagnose this problem. Start the engine in the dark. If you see lights under the hood, you need to replace the wires.
Don't forget about candles. If the engine does not want to start in dampness, then most likely the candles are asking for a replacement. Perhaps they stopped giving a strong spark. On a damp rainy day, moisture can accumulate on the candles, which leads to current leakage. Still often the ignition coils are to blame. Their cases crack, and condensate accumulates in them.
Cold engine running unstable
Sometimes VAZ brands are troiting cars while they are cold. But as soon as they warm up, they begin to work more stably. Here, too, there are several simple reasons. Most often, the ECU issues commands to create a too rich fuel mixture. If high-voltage wires are damp, this also leads to a similar effect. Wear on the parts of the piston group will cause tripping.
Troit when warm
It also happens differently. While it is cold, you can observe stable operation, but as soon as it warms up, the VAZ-2114 engine immediately triples the injector (8 valves). Often this is due to a burnt gasket, a faulty computer or problems in the ignition coil.
Problems at idle
This is a particularly common situation. It doesn't matter if the engine is cold or warm. In this case, there are very, very many reasons. It can be something elementary - from the failure of one of the candles to serious problems in the piston group. If the part is easy to change, then worn cylinders require serious repairs. VAZ-2114 is no exception.
So, unstable operation of power units at idle may be due to clamped valves, mismatch of timing belt marks, burnout of valves in the motor. They can also be damaged due to water hammer. Various electronic faults are also possible.
If troit, and then stalls
Many motorists have encountered this problem more than once. The search for possible causes and malfunctions begins. The ECU is tested, everything that is possible is checked, and the result is zero. The engine is still running and stalling.
In this case, you can check the condition of the injectors. For many, after a serious diagnosis, this problem was very easily, simply and inexpensively solved by cleaning the injectors and the fuel rail.
If the reason is hard to find
This happens too. And this is a fairly common situation. Car diagnostics through computer systems can help. Such an operation will test all the sensors, the electronic engine control unit, and as a result, it will provide information about exactly where the malfunctions occurred in the VAZ-2114 car.
If you are faced with this breakdown, do not panic. Everything can be repaired, and this effect is not fatal. If you cannot determine the cause yourself, contact an experienced specialist. But often everything can be detected and eliminated with one's own hands.
conclusions
It is important to carefully monitor the condition of the car and its individual components. With good care, timely replacement of consumables and fluids, this machine will work no worse than a Swiss watch. Well, if suddenly the unit finally fails, you can always purchase and install a new one - the price of a 1.6-liter engine is about 20 thousand rubles.
So, we found out the main reasons why one of the cylinders in a VAZ-2114 car may not work.
The engine 2111 is conditionally considered “native” for the VAZ 2114, since it has been installed since the creation of the car model for 4 whole years. This version of the internal combustion engine has a distributed injection and 4 valves and a volume of 1.5 liters. A tuned version of 21114 with a volume of 1.6 liters was also used by increasing the height of the cylinder block.
In 2007, the engines were “pulled up” constructively to Euro-4 standards, a 1.6-liter modification 11183 with 8 valves, an electronic gas pedal and an electric throttle, a polymer receiver instead of aluminum was put on the “four”.
Since 2009, the VAZ 2114 model has been modernized by a subsidiary of CJSC Super-Avto. A 16-valve ICE 21124 with a volume of 1.6 liters with a capacity of 89 liters began to be used. With. A year later, the power unit was re-upgraded, a modification of the 2126 engine of the same volume of 1.6 liters was used, but with a capacity of 98 liters. With.
Characteristics of motors 2114
Since the release of the Lada Samara VAZ-2114, the technical characteristics of the gasoline drive have been constantly improved. In principle, owners of domestic cars do not have questions about what kind of oil to pour into the engine, since standard requirements apply for Zhiguli, Lada and Samara - 5W30 or 10W30.
In addition, you should know which oil to use in transmission gears - the AvtoVAZ manufacturer's instructions recommend using the GL-4 lubricant group with a viscosity of 80W85 (mineral water), 75W90T (synthetics) or 85W90 (semi-synthetics).
The box becomes noisy after pouring synthetics, the oil is more expensive, but the lubricant is mostly imported, which provides additional guarantees. The domestic manufacturer most often produces semi-synthetics of medium quality for the engine and transmission gearboxes.

For high-quality maintenance of the internal combustion engine, the manufacturer of the motors issues a manual containing a description of the drive parameters, the frequency of replacing consumables and step-by-step repair operations. The same operating manual recommends oil volumes in gearboxes in the engine.
Engine design features
Initially, the engine of the VAZ-2114 car was 8 valve, had a volume of 1.5 liters, complied with Euro-2 standards, was marked 2111. In 2005, these engines were forced:
- to increase the volume to 1.6 l, the block is increased in height by 2.3 mm;
- several configurations were created - for Euro-2 version 21114-00, for Euro-3 model 21114-20 and for Euro-4 modification 21114-70;
- KSHM, valve system, camshaft correspond to 11183;
- the cylinder head received an enlarged combustion chamber of 5 x 8.1 cm, which made it possible to increase power.
An important feature of the 21114 internal combustion engine is phased, rather than pairwise-parallel injection, which was used in the original 2111. Attachments have become more compact:
- catcollector instead of a converter and a downpipe;
- injector rail instead of fuel return line.
The modernization also affected other components, for example, the January 7.2 or M7.9.7 controller was used, the ignition module was replaced with a 4-pin coil.
At the same time, engines from Kalina 11183 began to be installed on the VAZ-2114, which have some differences from the previous version:
- improved combustion chamber shape;
- the generator is mounted with a bracket, the tensioner is modernized.
In 2008, the 2114 engine received a new M73 ECU, and in 20011, the M74 "brains" to achieve Euro-4 standards. The control became completely electronic, but for another year the designers corrected the firmware defects until they created its final version I414DE07.
The next 2114 engine was installed on the car by a subsidiary of the manufacturer AvtoVAZ, called Super-Auto, in 2009. They became the 16 valve engine 21124 of the "tenth" VAZ family with improved characteristics:
- "high" blue block (197.1 mm);
- nozzles pressed into 2 - 5 main bearing supports that cool the pistons with oil;
- the depth of the holes in the valves is 5.53 mm, which ensures the safety of the valves in the event of a broken timing belt, major repairs are not required.
The following year, the fourteenth models began to be equipped with 21126 engines from export Priors. After tuning the motor 21124, the ICE device is distinguished by the following nuances:
- honed cylinders, gray block;
- crankshaft pulley and timing belt with a semicircular tooth;
- the weight of the connecting rod and piston group is reduced;
- there is no friction in the lower head of the connecting rod;
- glasses of candles are built into the head.
In the internal combustion engine, the principle of hydraulic compensation of valve clearances is used, the cylinder head gasket with a thickness of 0.45 mm is made of multilayer metal. The motor is equipped for Euro-3 with a collector 11194-1203008-10 or Euro-4 with a collector 11194-1203008-00. The resource of the pump has been increased due to the new design of the stuffing box and bearing, changes in the toothed pulley.
The ignition system has a separate coil for each spark plug. Phased injection, stainless steel fuel rail, controllers January 7.2 or M7.9.7.
Cons and pros
Depending on which 2114 motor is operated, the risks of the owner differ:
- 2111, 21183, 21114 and 21124 - do not bend the valve when the toothed belt breaks;
- 21126 - valve bending due to insufficient groove.
The main disadvantage of the last 16 valve versions is the lightening of the crank mechanism:
- the motor is adjusted to Euro-4 standards;
- to reduce weight, the length of the piston skirt is reduced;
- accordingly, the width of the oil scraper and compression rings decreases;
- the resource of the internal combustion engine is sharply reduced.
For example, in Japan, manufacturers abandoned Euro-4 standards, believing that reliability and high service life of the motor is more important for the consumer.
Drive power increased from 77 horsepower to 81 horsepower, then 82 horsepower, 89 horsepower, and 98 horsepower. In models with hydraulic lifters, periodic adjustment of this unit is not required, however, the quality of the oil in the system for the normal operation of the pushers must be high.
Maintenance schedule
In order not to have to make an expensive overhaul of the Lada Samara 2114 with your own hands, you should follow the manufacturer's recommendations for servicing the internal combustion engine:
| maintenance object | Time or mileage (whichever comes first) |
| timing belt | replacement after 100,000 km |
| battery | 1 year/20000 |
| Valve clearance | 2 years/20000 |
| crankcase ventilation | 2 years/20000 |
| Belts that power attachments | 2 years/20000 |
| Fuel line and tank cap | 2 years/40000 |
| Motor oil | 1 year/10000 |
| Oil filter | 1 year/10000 |
| Air filter | 1 – 2 years/40000 |
| Fuel filter | 4 years/40000 |
| Heating/cooling fittings and hoses | 2 years/40000 |
| Coolant liquid | 2 years/40000 |
| oxygen sensor | 100000 |
| Spark plug | 1 – 2 years/20000 |
| Exhaust manifold | 1 year |
Typical breakdowns
The very first 1.5 liter engine 2114 has disadvantages:
- periodic adjustment of valves;
- unreliable injection system;
- unfastening the nuts of the exhaust manifold;
- leaks in the gaskets of the fuel pump, distribution sensor of the ignition system.
The next 1.6 liter engine does not cause any special problems to the owner, with the exception of high vibration and noise loads. The weak point traditionally remains valves, which have to be constantly adjusted.
The internal combustion engine from Lada Kalina 11183 was installed on the fourteenth model solely for the sake of ensuring Euro-3 standards. It has typical shortcomings for a linear series, it does not differ in anything special.
The first sixteen-valve engine 21124 does not bend valves, the gaps in which are regulated by hydraulic pushers. However, the belt must be tightened after 15,000 km due to the large number of attachments. The second and last in the line of the fourteenth ICE models 21126 has increased power. In addition to typical malfunctions in the event of a timing break, the piston will bend the valve due to insufficient recess depth.
ICE tuning
For an atmospheric motor, the following type of tuning is usually used:
- receiver complete with 54mm inlet throttle body;
- direct-flow spider 4/2/1 at the outlet;
- camshaft Nuzhdin 10.93 or Dynamics 118 instead of factory equipment.
The dynamics of the internal combustion engine will improve, the power will increase to 85 - 90 hp. With. Then only the relief of the KShM, the refinement of the intake manifold and the milling of the cylinder head.
For 16 valve engines, tuning has the same principles, since it makes no sense to chip it. To reach 120 liters. With. You can increase the damper to 56 mm, use a direct-flow type exhaust, Nuzhdin 8.85 or Stolnikov 8.9 280 camshaft.
Thus, only one motor 21126 modification bends the valves on the VAZ 2114. All other engines are considered safe, they provide a real resource of about 270,000 km.
If you have any questions - leave them in the comments below the article. We or our visitors will be happy to answer them.
Over a long period of production, four engine modifications were installed on the fourteenth AvtoVAZ model, differing in power, volume and other characteristics. Various modifications were not the privilege of more expensive trim levels, but were the result of improving an outdated engine.
Engine modifications VAZ 2114
For ten years of serial production of the VAZ 2114, it was installed on it:
- 1.5i. Engine VAZ 2114 with a volume of 1.5 liters, with 8 valves. Its maximum power was 78 liters. C. at 5800 rpm. Torque at 3800 rpm reaches 116 N.m. At 100 km in a mixed cycle, gasoline consumption is 7.3 liters. In this modification, the internal combustion engine used an injector intake controlled through an EB, instead of an outdated carburetor, a new camshaft with corrected phases was installed. Thanks to the introduction of an injector into the VAZ 2114 engine, the engineers managed to increase the efficiency of the engine by increasing its power, while reducing fuel consumption. This was a big starting step in the development of the entire range of internal combustion engines of the Volga Automobile Plant.
- 1.6i. In 2004, they released a modification of the engine with an increased volume of 1.6 liters. He developed a power of 81 hp. With. at 5200 rpm and 125 N.m. at 3000 rpm. In the combined cycle, the engine consumes 7.6 liters of gasoline per 100 km. The VAZ 2114 engine with an injector and 8 valves received an increased volume due to a cylinder height increased by 2.3 mm, which made it possible to make a larger piston stroke. The ignition module has been replaced with a coil. The internal combustion engine turned out to be more powerful and environmentally friendly, but fuel consumption increased compared to the previous model.
- 16V 1.6і (124). Also in 2004, an engine with a volume of 1.6 liters was released, but already with 16 valves, that is, 4 for each cylinder. This motor already had 89 flywheel horsepower at 5000 rpm and 131 Nm of torque at 3700 rpm. The plant claims consumption in the combined cycle of 7.5 liters per 100 kilometers. The VAZ 2114 8 valve motor with an injector received a refinement in the form of an increase in the number of valves to 16 pieces. The rest of the characteristics remain the same. The car began to comply with the EURO-3 environmental requirements, gained an additional 8 horsepower and became a little more economical.
- 16V 1.6і (126). In 2007, this engine was greatly modified, the volume remained the same 1.6 liters, but the power already reached 98 hp. With. at a speed of 5600 per minute, and the torque develops 145 N.m. at 4000 rpm. Fuel consumption was reduced to 7.2 liters per 100 km.
They did a good job on the old VAZ 2114 engine for 3 years and made several changes:
- the connecting rod and piston group is lightened by 39%;
- the timing drive has been changed, it has become automatically tensioned;
- valve wells have decreased in size;
- the quality of cylinder honing has improved significantly.
All these and some less significant improvements increased the torque of the motor and now it developed 98 hp. With. and had a peak moment of 145 N.m. With all this, fuel consumption has significantly decreased.
This internal combustion engine turned out to be the most successful of all and became a great advantage of cars equipped with it.

Despite the differences, all VAZ 2114 engines have almost the same device, they are:
- Inline. The cylinders are located in the same plane one behind the other. The standard arrangement for so many pistons, it provides good heat dissipation and balancing during operation, which eliminates the ingress of large vibrations during operation on the car body.
- cast iron block. The cast iron block makes the engine heavier, but opens up tuning possibilities, such as installing a turbo with a large boost.
- Four-cylinder. Four cylinders are considered optimal for budget, economical engines. During operation, the pistons work in the order 1-3-4-2, thanks to this the motor runs smoothly. For example, on OKE, which has an engine with only two pistons, an additional balancing shaft is used to dampen vibrations.
- injection inlet. The injector has become the main plus of the VAZ 2114 engines, the internal combustion engine is controlled by many sensors that communicate with the ECU that controls all engine systems. This improves work efficiency, which has a positive effect on power and consumption.
- Distributed injection controlled by ECU. Making the right mixture when the engine is running is fundamental to achieving good internal combustion engine performance. The electronic control unit allows you to repeatedly increase the accuracy of the formation of the mixture.
- Piston diameter 82 mm. All VAZ 2114 engine blocks have the same piston group diameter, which gives excellent maintainability and tuning capabilities.
- Recommended gasoline AI-95. Fuel with a higher octane rating is more efficient and stable. Also, valves and gaskets are less likely to burn out on it.
These are quite simple engines, they are easy to work with, you can easily carry out independent repairs or tuning to increase power.
AvtoVAZ claims an engine resource of 150,000 kilometers, after which it will require a major overhaul. But with proper maintenance and regular oil changes, every 8-12 thousand km, the VAZ 2114 engine can drive up to 250 thousand km without big problems.
The bulkhead of the internal combustion engine requires a careful inspection of all components and assemblies. Mechanical damage indicates the need to replace the part. In addition, all gaskets and washers must be changed without fail.
Different models of VAZ 2114 engines have their own design flaws.
1.5i engine VAZ 2114 injector 8 valves:
- early fuel injection systems were unreliable;
- it is better to replace the exhaust manifold mounting nuts with brass ones, since the factory version is unreliable;
- oil flows from under the fuel pump, ignition distributor sensor and valve cover;
- valve clearances require frequent adjustment;
- some components of the cooling system wear out quickly.
1.6i engine VAZ 2114 8 valve injector:
- less often, but valve clearance adjustment is also required;
- great vibration and noise during operation.
16V 1.6і l (124) engine VAZ 2114 injector 16 valves:
The timing belt must be manually tightened every 15 thousand kilometers.
16V 1.6і l (126) engine VAZ 2114 injector 16 valves:
- a broken timing leads to costly repairs because the valves are deformed. The condition of the belt should be monitored much more carefully. The problem can be solved by installing a “plug-in” piston group;
- the main requirement for reliable operation of internal combustion engines are high-quality components and spare parts, so do not save on them.
Improving dynamic performance
For a budgetary improvement in the dynamic characteristics of the VAZ 2114 engine, you can take:
- finalize the intake and exhaust, namely to install a larger throttle valve, an intake receiver and an exhaust without a 4-2-1 catalyst, popularly called the "spider";
- split gear for phase adjustment;
- non-standard camshafts;
- if you have an 8-valve engine, the best solution would be to replace the cylinder head with a 16-valve one;
- refinement of the cylinder head of varying complexity can increase the maximum power to 120 hp. With. without wasting a resource.
Tuning can go as far as installing a turbocharger, nitrous oxide injection and other means to significantly increase power, but they are all quite expensive and reduce engine life.
When finalizing, do not forget that all procedures must be supplemented with the appropriate software for the control unit, otherwise your tuning may adversely affect the operation of the motor.

The appearance in the production of AvtoVAZ of the Samara family (originally Sputnik) was a real breakthrough for the domestic automotive industry of that time. The three-door hatchback VAZ-2108, which debuted in 1984, made a splash among Soviet motorists. Stylish design, advanced production technologies, outstanding driving performance - all this led to a resounding success. And this despite the fact that the body of the three-door hatchback clearly did not correspond to the utilitarian preferences of motorists of that time. The new model gained immense popularity, and its design even got its own nickname - "chisel" for its characteristic silhouette.
In 1987, the model 2109 was released - a five-door hatchback based on the G8. While maintaining all its advantages and chips, it was more suitable but the role of a family car. It only reinforced the success. In the future, the family was replenished with a four-door sedan. With minor changes, the first generation lasted on the assembly line until 2004.
The second generation of the Samara-2 family, in fact, is a restyling of the first generation models. The front part of the body was redesigned, lighting equipment and some visual elements of the exterior design were changed. The interior also received changes in the form of a new panel (the so-called "Euro-panel"), as well as improvements to some elements.
The line of power units VAZ-2114 (Samara-2)
During the release, various modifications of motors already known from other models of the manufacturer were installed on models of the Samara-2 family. The widest choice was offered by model 2114 - the heiress of the legendary "nine" VAZ-2109.
All the engines that were equipped with the “fourteenth” are in-line atmospheric fours. The carburetor power system was gradually becoming a thing of the past, so the restyled successor to the “nine” is found exclusively in injection versions. This made it possible to modernize the engines and fit into environmental standards.
- 1.5 l. 8 cells (77 hp) - index 2111;
- 1.6 l. 8 cells (81 hp) - index 21114/11183;
- 1.6 l. 16 cells (89 hp) - index 21124;
- 1.6 l. 16 cells (98 hp) - index 21126.
Engine 2111 (1.5 l., 8 valves)
At its core, the engine is a redesigned modification of the well-known 21083 unit, which appeared on the legendary G8. Processing touched, first of all, the food system. Instead of a carburetor system, the engine began to be equipped with an injection system. The design of the connecting rod and the camshaft also received changes. All this allowed to improve performance indicators. Increased power and torque. In addition, the engine began to comply with Euro-2 environmental standards.
Gas distribution mechanism with an overhead camshaft and belt drive. Its nice feature is that when the belt breaks, the valves are not damaged.
Typical problems
Floating idle speed most often occurs due to a malfunction of such components:
- Idling regulator;
- Throttle position sensor;
- vacuum booster.
If the existing symptoms are added to the fact that the engine stalls on the go, then you should also pay attention to the condition of the mass air flow sensor (MAF).
If the engine began to run unevenly and “troit”, then first of all you should pay attention to the compression indicators. A noticeably lower compression in one of the cylinders most likely indicates a burnt valve. If the spread is small or exists in several cylinders, then the valve clearances should be checked. There is a good chance they need to be adjusted. A similar symptom may also indicate problems with the gasket between the cylinder head and the cylinder block. However, even if such symptoms are not observed, do not forget about regularly checking the thermal clearances of the valves, as well as adjusting them. The manufacturer recommends performing such a check every 20 thousand km. If everything is in order with compression, but there are similar symptoms, it is necessary to check the ignition module.
Often noises and knocks become companions of this motor. All of these can be the cause of misadjusted valves. If you hear an increasing loud dull metallic sound when you press the gas pedal, the engine will most likely need repair. There are several main reasons for this symptom:
- Knock of main bearings;
- Knocking rod bearings;
- Piston knock.
The operating temperature range of the coolant for this unit is 95-103 degrees. However, there are cases when the engine simply does not heat up to such indicators. The main reason for this behavior of the motor is a malfunction of the thermostat. Some owners have to replace it almost on a regular basis. All this is a consequence of the low quality of spare parts.
Other common malfunctions of this engine
- valve cover leaks;
- Depreciation of the components of the cooling system;
- Injection system failures on old copies;
- Breaking of the fastenings of the intake exhaust pipe (treated by replacing steel threaded connections with brass ones).
The engine is very common and enjoys well-deserved popularity among many motorists. Its simplicity, maintainability and good knowledge make it easy to deal with existing shortcomings and typical malfunctions.
The manufacturer officially declares a resource of 150 thousand km. However, practice shows that many specimens nurse deep beyond 200 thousand km. A lot depends on the operating conditions and attention to maintenance.
Engine 21114/11183 (1.6 l. 8 cells)
The unit is a continuation of the development of the motor with the index 2114, and, accordingly, its progenitor 21083, which was installed on the first generation of the Sputnik / Samara family. The changes affected mainly the cylinder block. Its height has increased, and accordingly the piston stroke. The working volume increased to 1.6 liters. Performance in terms of power and torque has also increased. In practice, this manifests itself in the form of improved elasticity and greater traction. The improvements made allowed the engine to comply with Euro-3 environmental standards.
Car owners may call this engine in different ways. You can find such names as the engine 2114 (out of habit with an 8-valve Euro-2), Kalina, as well as the corresponding official indices 21114 and 11183. The differences between engines with these two indices are that they were produced on different conveyor lines.
The huge similarity with the 2111 engine endowed this unit with almost identical problems and malfunctions. It is also necessary to regularly monitor the condition of the valves and deal with uneven operation.
Of the unpleasant individual features - noisy work similar to the sound of a diesel engine. With the rest of the noise, things are the same as in the 2111 motor.
However, despite the common roots and problems, the masters note that 21114/11183 is still a little less capricious. At the same time, there is still no risk of bending the valves when the timing belt breaks.
Similar motors and resource indicators. So, the manufacturer indicates 150 thousand km before the overhaul, however, in practice, the indicators easily exceed 200 thousand km, and sometimes reach up to 300 thousand.
Engine 21124 (1.6 l., 16 valves)
The motor with the index 21124 was replaced by the unit 2112 on the conveyor. The sixteen-valve “four” increased the volume to 1.6 liters due to the use of the “high Kalinovsky” cylinder block. Improvements were made to comply with Euro-3 environmental standards. Thanks to this, traction at low revs has increased, but at the same time it has become more calm in nature. Compared to the "twelfth" increased noise.
The problem that was most feared by the owners of the sixteen-valve of the previous generation with the index 2112 was solved. Due to the special design of the pistons with holes, the valves will not bend when the timing belt breaks. This is a significant advantage over the "twelfth".
Due to the presence of hydraulic compensators, there is no longer a need to constantly monitor the thermal clearances of the valves. However, these parts are most often the cause of unpleasant knocks from under the hood. In addition, the cause of knocking may be a problem with oil pressure. Moreover, the indicators can be both below and above the norm.
The old problem with valve adjustment has been replaced by a new one. It is recommended to monitor the timing belt tension and tighten it every 15 thousand km.
There are also problems with knocks of a different nature. They can be called "branded" for VAZ engines. This is the knock of main and connecting rod bearings, as well as pistons.
The engine is not deprived of other "proprietary" malfunctions:
- floating turns;
- Engine "troit";
- Stalls at idle or in motion;
- Temperature problems.
All these problems are familiar from other units. For example, for the same 2111. The roots of the problems are common, so the solutions can be found in the corresponding section of this article.
If the car does not start at all, then the check must be carried out according to the following scheme:
- Starter and battery;
- Ignition system;
- Power system and fuel pump.
In case of problems with traction, and specifically with its decrease, you should check the pressure in the fuel rail, as well as the condition of the injectors. Maybe their filters are clogged.
A characteristic feature of the engine was increased vibration. There can be many reasons for this. Among them, the idle speed controller, high-voltage wires, candles, lambda probe. And this is not a complete list. To identify the cause, a high-quality diagnosis from an experienced master will be required.
This engine easily overcomes the standard resource indicators from the manufacturer of 150 thousand km. According to the experience of the owners, most specimens easily take care of more than 250 thousand km. In addition, in an unspoken rating, this engine model is considered one of the most successful at VAZ. This becomes especially true for owners who prefer to tune and modify the engine of their car.
Engine 21126 "Priora" (1.6 l., 16 cells)
A continuation of the evolution of VAZ 16-valve engines was a motor with an index of 21126. It is a development of 21124, but with some changes. Among them:
- Lightweight ShPG (connecting rod and piston group);
- Better surface finish;
- Honing of cylinders with more stringent requirements.
Timing drive - belt, with overhead camshafts. But unlike its predecessor, when the valve breaks, it bends. There is a radical solution to this design feature - the replacement of pistons. If the engine is in a standard design, then you just need to carefully monitor the condition of the belt. Moreover, the problem with its weakening was solved by installing an automatic tensioner. The type of belt used has also been changed.
Typical malfunctions
If you feel a loss of power, then most often the reasons for this are in such phenomena:
- Loss of compression due to a burnt cylinder head gasket;
- Cylinder wall wear;
- Wear of piston rings;
- Piston burnout.
The result of unstable operation and refusal to start, there may be a problem with the pressure in the fuel system. In addition, such symptoms cause sensor malfunctions, air leaks through leaky hoses or their connections, malfunctions in the timing, or problems with the throttle.
If the engine is clearly “troiting”, then, first of all, it is necessary to check the compression indicators in order to eliminate the problem with valve burnout. But more often it is caused by faulty spark plugs or a failed ignition coil. Sometimes the reason lies in the condition of the nozzles, namely the degree of their contamination.
Floating speed is a quite typical disease of VAZ 16-valve valves. Often, in addition to this, the engine runs unevenly. In this case, first of all, it is necessary to check the mass air flow sensor (DMRV). If it is working, then most likely the cause is the throttle. It is necessary to clean it, and possibly replace its position sensor (TPPS). At the same time, you should also check the condition of the idle speed controller (IAC).
Not done on this engine and without a "proprietary" headache with a thermostat. Still, it becomes the reason that the engine cannot warm up to operating temperature. However, if there are severe frosts outside, the old-fashioned way with a cardboard box in front of the radiator will probably help.
Some characteristic sores of other VAZ engines also migrated to 21126 Priora. So, if you detect knocks under the hood, you should first check the condition of the hydraulic lifters. Most often, they are the culprits of unpleasant knocks. At the same time, knocks that are associated with main and connecting rod bearings, as well as pistons familiar from other VAZ engines, can also occur. This is already a serious malfunction, which is fraught with difficult engine repairs.
Minor problems, in the form of a refusal to start, most often lie in the following malfunctions:
- Starter and battery;
- Ignition coil;
- Candles;
- Fuel pump malfunctions;
- Clogged fuel filter;
- Defective fuel pressure regulator.
Having improved the performance indicators, the 21126 motor is still slightly inferior to its predecessor 21124 in reliability. Although it cannot be said that it is inferior to very much. This is mainly due to the more complex design. Nevertheless, it is one of the best domestic motors, which also fits into modern environmental standards.
The declared resource is 200 thousand km. Compared to the officially declared resources of its predecessors, it has increased. However, in practice, older motors with a simpler design generally last longer. Judging by the reviews of real operation, on average, the real resource corresponds to that indicated by the manufacturer. Sometimes it can be more, sometimes less. Much depends on the operating conditions and the level of service.
On cars of the Samara 2 series, the Volga Automobile Plant installed injection engines with electronic, distributed fuel injection. And for the VAZ 2114, which appeared in 2001, and was launched into the series in 2003, such a power plant was developed - model 2111. In subsequent years, various modifications of this machine were produced and other engine models were installed on some of them, such as - 21114, 11183, 21124 and 21126. But the most massive production cars were VAZ 2114 with engines of models 2111 and 11183.
Engine tuning theory
The concepts of "engine tuning" and "budget tuning" are incompatible, so I have almost nothing to say here. Of course, the most effective measure in tuning the motor is to increase the working volume. Only this gives a simultaneous increase in power, torque over the entire speed range - from a modified 1.8-liter VAZ-2112 engine, you can get a torque of more than 20 kg / m, and curb the maximum thrust of 10 kg / m of a standard 2110 engine already from 1500 rpm min! Another measure is the installation of various types of compressors, the replacement of fuel with a more "combustible" one (nitromethanol, i.e. alcohol), the supply of an additional fuel oxidizer (nitros), but this is expensive. And even the little that can be done with a reasonable investment requires the hands of a master and great experience. Therefore, I will dump here not only the motor itself, but also the power supply, ignition and exhaust system. timing- the gas distribution mechanism is the only place available to budget tuning where you can extract the "increase". Theory. The camshaft determines the valve lift (and the larger it is, the better - over the entire engine speed range), as well as the time and duration of the valves opening. Unfortunately, we cannot raise the valve as much as we want: the valve springs will choose the gaps between the coils and break. To raise the valve even higher, refinement of the cylinder head is required - first, lower the valve seats (for example, for MM54 - by 1 mm), then more radical measures - replacing springs, pushers, etc. - not budget. Therefore, for the motor 2108-2111, the maximum allowable valve lift is 9.7 mm, i.e. without alterations to the timing, you can put the camshaft "", "Nuzhdin" or their equivalent.A few words about the time and duration of opening the valves - the width of the phases. The higher the engine speed, the earlier to the top dead center (TDC) you need to open the intake valve and close it later. This is necessary to provide a mixture that has a large inertia at high speeds, the ability to fill the cylinder as completely as possible and release the burnt charge. Accordingly, in the exhaust phase, it is also necessary to act ahead of schedule, so that by the time the hot mixture is reached, when the hot mixture is no longer doing work, let it start to leave the cylinder, and also keep the exhaust valve open after TDC in order to remove as much exhaust gases from the cylinder as possible . At low speeds, this leads to the fact that the exhaust gases that have not yet completely escaped enter the intake system, not letting in a fresh mixture, which reduces traction at the bottom, makes idling very unstable (therefore, on shafts with wide phases, it is necessary to increase the idle speed) . At high speeds, the overlapping of the intake and exhaust phases allows for a more continuous flow of gas through the CPG and, accordingly, burns more mixture and significantly increases the efficiency of the motor. The dependence is non-linear: a gradual increase in phase overlap first gives an increase in torque at high speeds, gradually shifting the maximum to ever higher speeds. After a certain moment, the subsequent increase in phase overlap has the opposite effect - a drop in power and torque even at high speeds. If we are talking about a two-shaft motor. then the task of the master is to find such a position of the shafts at which we will get the maximum torque at the maximum possible speed, and thus obtaining the maximum power. In the case of a single-shaft engine, you don’t need to think about it - the phase overlap is provided by the manufacturer, you just need to accurately set the position of the camshaft relative to the crankshaft, and the overlap can only be changed by changing the shaft. To get "tractor" thrust, you need a shaft with minimal phase overlap and maximum valve lift. We will get more traction at low revs, which is very important for a city with eternal traffic jams.
The technical characteristics of the 1.6 liter engine do not differ much from previous versions. Compared to the one and a half liter, this engine has become more powerful by only 4 hp. Apparently, the designers of AvtoVAZ, in pursuit of increasing the engine resource, completely forgot that they would also need to add power. Therefore, happy car owners themselves are trying in every possible way to “add horses” under the hood. There are cases when the craftsmen managed to squeeze out up to 140 hp. from the VAZ 2114 engine, engine tuning added power almost twice as much as the factory specifications show. But as power increases, engine life decreases. Therefore, we will talk about how to increase power and at the same time reduce the life of the VAZ 2114 engine as little as possible.
It's no secret that in its regular, that is, in serial form, the engine develops far from all the power that it is capable of. You can set up the firmware in a new way, but you won’t be able to change the load curve much without lowering the ecology class. You can buy a "racing cam" to install it instead of the stock one. But then, for the new phases, it will be necessary to change the firmware as well ... Let's consider what happens if we use only the available tuning methods. Let's say right away that on the VAZ-2114 hatchback, the increase in power can be 20% or even 25%, and we are talking about only 8 valves. There is no need to bore the valve channels. During tuning, the engine 21114 (1.6 l) was finalized. List of works: Boring of saddles on the inner diameter, which is equivalent to increasing the valve;
The necks of the channels also had to be squandered a little. Thin duralumin plates were installed, which made it possible to dissolve the springs by 1.5 mm; Regular valves were replaced with lightweight ones; Guide bushings were machined from special brass;
A split gear appeared in the design;
Valve crackers were replaced with imported ones just in case; A shaft with "narrow phases" was installed: outlet - 66 degrees, inlet - 70, opening angles - 246 and 250 degrees, respectively. The valve travel is 9.5 and 9.6 mm. Our new motor remained "not plug-in" - the valves do not reach the pistons. When checking on the stand (sensors were disabled), the result was not impressive.
If you install engineering firmware, you can choose the parameters "from and to". And then the picture looks better...
All sensors, including the lambda probe, were connected in the latter case. It was possible to remove 96 “forces” at 5300 rpm!
How not to increase the power of the VAZ 2114!
✔ Do not attempt to bore channels. This operation can be performed even in the absence of ball cutters, but in garage conditions nothing will work even with cutters. The bottom line is that the accuracy of the installation of the cutter is important - the error should not exceed 1-2 microns. ✔ As you can see, on the stock VAZ-2114 hatchback, the power increase was 24%, and this is without installing a “chandelier”, “improved exhaust” and other expensive elements. ✔ It makes no sense to buy a "racing cam" without having the right tuning firmware.How to make engine tuning VAZ 11183
It is clear that the mandatory step in tuning the 11183 motor will be the replacement of the ECU. It's simple: the regular M74 unit cannot be flashed, but "January 7.2" is a good and time-tested solution. You will also have to abandon the “E-Gas” option, which means replacing the throttle assembly and receiver.
The intake tract details were borrowed from the 2111 engine. A “under the cable” pedal was installed, and the engine began to look human.
Everything works well with the January controller, but stock firmware is not an option if the camshaft has been replaced. And he, in turn, has the following parameters: Release phase width - 104; Inlet phase width - 109; Opening angle at the outlet - 272; Inlet opening angle - 268; Valve travel (exhaust / intake) - 9.5 / 10.1 mm. After installing a new shaft, the motor became "plug-in". However, on the 2114 hatchback, increasing power almost always comes with a trade-off. In this case, reliability had to be sacrificed. What's improved: Maximum torque increased by 14 Nm; Power also increased - the limit of "90 forces" was passed. By the way, any tuning leads to a decrease in durability. Make a choice.
