Experts consider the VAZ 11186 engine as a modernization of the 21114 engine, a secondary modification of the 21083, or an improvement in the characteristics of the 11183 internal combustion engine. The first option is considered more correct, since the design of 11186 and 21114 is absolutely identical, with the exception of the pistons. The 11186 engine is equipped with AvtoVAZ products, and the previous version of the internal combustion engine was equipped with pistons from the manufacturer Federal Mogul (USA), which developed it under a contract with the Volzhsky Automobile Plant.
ICE 11186 compared to 11183
Characteristics of motor 11186
The project of a “people's car” at a budget price for the average LowCost user was seriously hampered by the economic crisis. For the Lada Granta Standard configuration, the technical characteristics of the existing ICE 11183 were sufficient.
However, for the Norma and Lux trim levels, a more powerful internal combustion engine was needed, so the management of AvtoVAZ, not having sufficient funding for the project of a new engine, came out of the situation as follows:
- the existing version 21114 became the basis for the ICE 11186;
- to reduce costs, pistons from the American manufacturer Federal Mogul were replaced with domestic products of a suitable size;
- The manufacturer changed the engine markings, but no more design changes were made.
Piston 11186 is smaller than 11183
Unlike 11183, the piston of the 11186 motor bends the valve when the timing belt breaks, but the performance characteristics are improved:

Since the engine does not have hydraulic valve lash compensators, it is practically not important for the user which oil to choose based on the fuel manufacturer. Both domestic and foreign companies are suitable, for example, ZIK, Lukoil, Mobil, Rosneft. On the other hand, relevant information is which oil to pour into the engine based on viscosity:
- for regions of the Russian Federation, the manufacturer recommends all-season oils 10W40, 5W40 and 15W30;
- Synthetic and semi-synthetic lubricants are allowed;
- It is better not to use mineral oil.
To reduce temperature loads on the valves, the engine circuit provides nozzles that inject oil onto their surface. Unlike homemade channels, nozzles fire only when pressure increases, that is, when the lubricant heats up from intense loads. Oil does not enter the crankcase and does not cause increased wear of gaskets in the engine.
Description
The Grant engine is a modernized version of the long-produced engines 21124 and 11183. It differs from its predecessors by the presence of a 39% lighter connecting rod and piston group developed by Federal Mogul. For the VAZ-11186 engine it is manufactured directly at AvtoVAZ OJSC.
As a result of the modernization, significantly:
- power increased;
- exhaust toxicity has decreased;
- fuel consumption has decreased.
The cylinder head has become much stronger, since during manufacturing it undergoes a special heat treatment cycle. In addition, it is further strengthened by metal gaskets.
Despite the fact that all the motors in the line are assembled according to an identical design, the 11186 engine has a number of design features. Among them are:
- Improved cooling system for the block and cylinder head. The piston group is covered with a cooling jacket along its entire height and is equipped with piston cooling nozzles, which prevents deformation of the cylinder block due to uneven heating.
- Using a new camshaft drive design equipped with an automatic tensioner.
- The original design of the crankshaft, equipped with special oil channels, which are closed with plugs. This required the use of high-strength cast iron for its manufacture.
A significant drawback of the grant engine is that if the timing belt breaks, the valves bend, which can lead to failure of the power unit as a whole (breakage of pistons and cylinders). In order to protect the engine, a highly reliable drive belt is installed at the manufacturing plant during assembly, which is manufactured by the American company Gates Rubbler Company. The service life of this belt is at least 200 thousand kilometers.
Interesting: As a result of modernizing the VAZ-11186 engine, it became possible to equip it with an electric throttle valve drive (E-gas). This allows you to increase its power to 90 hp. With.
Design Features
By default, the 11186 engine retains all the design features of the original 21114, from which it originated:
- volume 1.6 l;
- the block height is 2.3 mm greater than that of 2110;
- crankshaft with an increased crank radius by the same 2.3 mm (piston stroke 75.6 mm, respectively);
- ShPG, flywheel and crown from 2110.
Motor design 11186
In addition, a feature for the 11186 engine is the bending of the valves on the pistons when the timing belt drive breaks:
- the piston skirt is reduced here to make it lighter;
- It is physically impossible to make a deep hole for the valve inside the piston.
Diagram of internal combustion engine components 11186
The manufacturer's manual contains a description of the components and parameters of the internal combustion engine, which are most often compared with the characteristics of the 11183 engine, which has the most similar markings. The main differences between these power drives from the same manufacturer are:
- torque is 15 Nm more;
- power 87 l. With. instead of 82 l. With.;
- motor 11186 has been produced since 2011, and its predecessor 11183 since 2004;
- instead of serial pistons from 2110 weighing 350 g, a lightweight version 21116 weighing 240 g is used;
- connecting rod length increased from 121 mm to 133.32 mm;
- the piston skirt has a graphite coating, the metal in the area of the first ring is anodized;
- combustion chamber 30 cm3 instead of 26 cm3;
- compression ratio increased from 9.6 to 10.5;
- The cylinder head gasket is all-metal, its thickness has been reduced from 1.2 mm to 0.43 mm;
- the cylinder head is 1.2 mm higher to compensate for the enlarged combustion chamber;
- the diameter of the bolts was reduced from M12 to M10 to reduce cylinder deformations during tightening;
- the flow channels in the cylinder head have been increased in diameter, nozzles have been installed to cool the piston heads;
- the working chamfer under the valves is maintained longer due to the strengthening of the aluminum alloy using a special technology;
- since the holes in the pistons are not enough to ensure the safety of the valves, a high-strength timing belt from the Gates manufacturer is used;
- the camshaft V-belt received an automatic tensioner, which had not previously been used in VAZ engines;
- the piston system is protected externally from overheating by a cooling jacket integrated into the cylinder block;
- the length of the receiver channels has been increased, the characteristics of the internal combustion engine are close to those of a 16 valve engine;
- the catalytic collector has a flattened block, which made it possible to separate the ducts and get rid of power losses and turbulence;
- the generator is mounted on a bracket, so its drive belt is not overtightened, like 11183, and lasts longer;
- The cabin heat exchanger and expansion tank are included in the thermostat in parallel, the operating error has decreased to 2 degrees instead of 5 degrees.

According to the AvtoVAZ plant, the ICE 11186 has a potential of 120 hp. (without resource reduction) or 180 l. With. (the resource will be reduced due to intensive wear of the piston). The manufacturer recommends tuning exclusively through modifications of components and mechanisms without the use of turbines.

Another feature of the engine is the location of the water pump (pump), which is rotated by the same timing belt. That is, in case of coolant leaks or characteristic noise/whistle/hum in the timing drive area, checking the belt is mandatory. If the pump bearing crumbles and the belt comes off, then in addition to replacing the water pump housing and belt, you will also have to go through the cylinder head, removing bent valves from there.
AvtoVAZ uses a very reliable Gates belt as the original belt. Often the service life of the Gates belt is much higher than the service life of the pump and tension pulley of the Lada Granta 8-valve engine.

The Lada Granta was equipped with two 8-valve and two 16-valve 1.6-liter engines. Eight-valve engines with 82 and 87 hp. had an index of 11183 and 11186, respectively. Sixteen-valve power units with a capacity of 98 -106 hp. carried the index 21126 and 21127.
Advantages and disadvantages
The main advantage of the motor is the fact that the manufacturer has already managed to increase the power to 64.2 kW. In addition, it is possible to boost the motor without loss of service life. That is, the owner will not have to make major repairs more often than scheduled.
The disadvantages of ICE 11186 are:
- “meeting” of the piston with the valve in the event of a break in the timing belt drive;
- periodic valve adjustment;
- non-repairable ignition unit.
Adjustment of valves
The advantages of the engine in comparison with the existing versions of the internal combustion engine of the AvtoVAZ manufacturer at the time of its creation are:
- do-it-yourself overhaul after the piston group has reached the end of its service life at least 3 times using different repair kits;
- increased volumes of combustion chambers;
- built-in piston cooling system;
- the hinged one is secured with brackets and has automatic tensioners;
- modernization of the cylinder head and crankshaft;
- piston and crankshaft relief;
- use of parts from existing engines.
Therefore, during repairs and tuning there are no problems with spare parts and components. Maintenance is cheaper than foreign-made engines.

I think it’s no secret that the Lada Granta is available with 4 different types of engines. And each power unit of this car has both its advantages and disadvantages. And many owners who want to buy a Grant do not know which engine to choose and which of these engines will be better for them. Below we will consider the main types of power units that are installed on this car.
The biggest advantage of this engine is that it has a very reliable timing system and even if the timing belt breaks, the valves will not collide with the pistons, which means that you can simply change the belt (even on the road), and you can drive on. This engine is the easiest to maintain, since its design is completely identical to the well-known unit from 2108, only with an increased volume.
If you want to avoid problems with repair and maintenance, and not be afraid that the valves will bend if the belt breaks, then this choice is for you.
Judging by the reviews of many owners of Grants and Kalina 2, which have already had this power unit installed, the power in it has actually increased and this is felt, especially at low speeds. Although, practically no elasticity has been added and in higher gears the acceleration does not occur as quickly as we would like.

The larger the engine capacity, the more powerful the car, and, as a rule, the larger it is. There is no point in installing a small-capacity engine on a large car, the engine simply cannot cope with its weight, and the opposite is also pointless - installing a large engine in a light car. Therefore, manufacturers are trying to select a motor. to the price of the car. The more expensive and prestigious the model, the larger the engine capacity and the more powerful it is. Budget versions rarely boast a cubic capacity of more than two liters.
Engine displacement is expressed in cubic centimeters or liters. Whichever is more convenient for you.
What cars was it used in?
Created in 2011, the 11186 engine is used as a power drive for several models of the auto manufacturer AvtoVAZ:
- Lada Kalina II – station wagon, sedan;
- Lada Granta (Lux and Norma equipment) – liftback, sedan;
- Lada Priora – sedan, station wagon, hatchback;
- Lada Largus – minivan, station wagon, van;
- Lada Vesta - station wagon;
- Lada XRay is a compact crossover/high hatchback.
Lada XRay
Improved engine characteristics allow it to be used on any front-wheel drive car in the event of a swap rather than engine tuning.
Comfort and speed
Compared to previous models, the Lada Granta turned out to be quite a playful and fast car. This is confirmed not only by successes in sports competitions. In addition to the powerful power plant, the manufacturer took care of the interior design. Now this is a truly European and Western car, which has everything you need for comfortable and cozy travel. We must not forget that comfort is one of the aspects of safety.
Despite the budget class, the interior of the car is presented presentably.
- In the classic version of the Grant, it comes with door upholstery in decorative materials, separate rear seat backs, and additional sill seals. At the same time, the security system has been thought out.
- As standard, the car has inertial seat belts, airbags for passengers and drivers, and comfortable headrests.
The Grant has a steering wheel height adjustment function and an electric power steering. The car windows are made as athermal modifications. The cabin air filter and multifunctional climate control system ensure the absence of unnecessary odors and cold. It is convenient to drive Granta at any time of the year: both in the summer heat and in the winter cold.
Maintenance
In accordance with the manufacturer's regulations, engine 11186 must be serviced in the following order:
| Maintenance object | Time (year) or mileage (1000 km), whichever comes first |
| Timing belt | 3/50 |
| battery | 1/20 |
| Valve clearances | 2/20 |
| Crankcase ventilation | 2/20 |
| Belts that drive 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 | 2/40 |
| Oxygen sensor | 100 |
| Spark plug | 1 – 2/20 |
| Exhaust manifold | 1 |
This is exactly the frequency of maintenance that the ICE 11186 device is designed for.
Engine characteristics Grants
The VAZ 11183 engine was first used for installation on the Lada Kalina. This is a four-cylinder device with 8 valves and a volume of 1.6 liters. Structurally, this power unit is almost no different from the 21114 engine, widely used by the manufacturer on its models, starting with the VAZ-2109 and ending with modifications of the Kalina.
According to experts, both 11183 and 21114 have the same parameters and characteristics of all parts of the engine: block, camshaft, head, valves, crank mechanism, etc. That is, in fact, these are the same engine with different names .
11183 is characterized by increased environmental friendliness, reliability and increased volume. The timing drive is a belt drive, located in such a way that a broken belt does not bend the valves. This is also facilitated by deep piston recesses.
According to the plant, the service life of 21114 does not exceed 150 thousand km, but in practice the engine has successfully covered a mileage of 200 thousand. The service life of 11183 officially has an indicator of 200 thousand km.
Engine 11186 is a thoroughly modernized version of 11183 and is completely similar to engine 21116, created specifically for the Lada Granta. The differences between 11186 and 21116 lie in the manufacturer of the piston system: the first uses designs from the Federal Mogul plant, the second from AvtoVAZ. 11186 is considered the main engine of the Lada Granta liftback modification.
The modernization of the engine was carried out by engineers from the Volzhsky enterprise. They managed to achieve a reduction in the specific consumption of fuels and lubricants, while the minimum engine resource increased to 200 thousand km.
The new Lada Granta liftback car is equipped with 3 types of engines: 11186, 21126 and 21127. The VAZ 21126 with 16 valves and 2 camshafts is considered the main engine of the car. The technical characteristics of such an engine allow it to develop power up to 98 hp. and be combined with an automatic transmission. But in comparison with 21116, the 21126 engine has higher gasoline consumption and worse dynamic performance.
An even more advanced power unit 21127 allows you to achieve a power of 108 hp. At the same time, fuel consumption per 100 km range is reduced by almost 1 liter. The technical characteristics were improved by introducing into the mechanism of the intake manifold of the engine a part that performs passive supercharging.
The greatest interest among fans of AvtoVAZ models is the Lada Granta liftback, equipped with the 21127 engine, since it combines high power with the possibility of installation on an automatic transmission.
Malfunctions: causes, elimination
Like all internal combustion engines with mechanical adjustment of valve clearances, the 11186 engine requires periodic adjustment of this characteristic. In addition, during operation, characteristic “diseases” of this particular version of the power drive were identified:
| Bend valves | broken timing belt | periodic wear monitoring |
| Ignition system interruptions | failure of the corresponding block | replacing the ignition module |
| Increased oil consumption | wear of the main bearings, stuck piston rings | replacement of consumables |
| Knock | wear of pistons, bearings | replacement of parts |
When repairing piston and crankshaft engines, it is recommended to use original components from the AvtoVAZ manufacturer. Because only he uses special technologies for strengthening structural materials. From third-party companies, the metal may be “raw”; the resource of such consumables cannot be analyzed.
The ignition module cannot be repaired
VAZ 11183/21114
The volume of the power plant is 1.6 liters. In fact, it is a development of the old one and a half liter engine. Engineers managed to increase reliability by replacing the materials used to produce some elements and optimizing the design. If we talk about the resource, the manufacturing plant itself set the mark at 150 thousand kilometers. Practice shows that
values of 250-300 thousand are quite achievable if certain recommendations are followed. The main requirement is timely oil changes, effective heat removal will reduce wear on all engine elements. A big plus of the engine is its resistance to timing belt breaks; even in a critical situation, the likelihood of valve bending is minimal.
Tuning
Initially, the manufacturer builds additional potential into its engines in order to make any changes in future versions. However, the 11186 engine can be upgraded on its own. The following type of tuning is considered standard:
- camshaft - replacement of a standard part with a Nuzhdin 10.93 or Dynamics 108 camshaft;
- cylinder block - boring to 86 - 88 mm (pistons and connecting rods of appropriate sizes will be required);
- intake manifold - zero resistance filter, damper with a diameter of 54 mm, grinding of the internal surfaces of the channels;
- catcollector - replacement with a spider having a 4:2:1 scheme;
- Timing - installation of T-shaped lightweight valves;
- Cylinder head – head milling.
Zero resistance filter
Tuning that adds 30% of power is considered safe (“resource-producing”) for the engine. That is, for 87 hp. With. it will be 29 liters. s., which results in about 115 hp. With. Further tuning becomes dangerous, since the service life will decrease in arithmetic progression. This method is used by athletes, but not by ordinary car enthusiasts.
Thus, the 11186 motor has one significant drawback - it bends the valves. The manufacturer partially corrects the situation through high-life timing belts from Gates. In other respects, the internal combustion engine was superior to its existing counterparts at that time, with the exception of the 21114 engine, which was taken as the basis.

Reviews
Drom.ru experts tested the Lada Largus van with the new VAZ 11182 engine:
Impressions of the new engine from auto.ru:
- The motor works differently. The acoustic sound from the engine compartment is different.
- Vibrations from the engine are not transmitted to the steering wheel, as on the Grant.
- At 110 km/h in 5th gear the engine runs at 3000 rpm.
- The fuel consumption of the VAZ 11182 engine (90 hp) is 1.5 l/100 km less than that of the VAZ 21129 (106 hp)
The cylinder head cover was previously secured with two bolts. Now it is attracted at six points along the perimeter. This improved the tightness of the joint and, in combination with a new gasket, should rid the engine of the old VAZ problem - oil fogging at the interface with the cylinder block. The crankcase ventilation system has also been changed. A more efficient oil separator reduces engine oil consumption.
Valve adjustments need to be done less frequently, but this procedure is now more complicated. So, for adjustment, it is necessary to dismantle the timing belt (but still change it at the same 90,000 km) and the camshaft, and instead of cheap washers, you need to purchase new pushers of a pre-calculated size.
By reducing the thickness of the rod from 8 mm to 5 mm, the valves began to weigh less. The camshaft lost in the width of the working surface (from 15.3 mm to 11 mm) and the width of the cams (from 17.7 mm to 6 mm). Instead of eight counterweights, the crankshaft was left with only four: how this will affect the resource is a question.
AvtoVAZ promises savings due to the new engine of 4,900 rubles per 20,000 km. Of these, 2000 will be saved by reduced gasoline consumption (by approximately 200 ml/100 km), 2900 will be saved by the valve adjustment procedure. The factory is being disingenuous about the cost of adjustment. According to the recommended prices for maintenance, it costs 1700-1800 rubles. And this saving is every 30,000 km. But maintenance - 90,000 km for a new engine is already more expensive: 21,300 rubles versus 18,300 rubles. And this despite the fact that the cost of new pushers is not included in the base price; you will have to pay for them on top.
The motor has become on average 2.4 dB quieter and vibrates less. The throttle assembly and fuel rail have been changed. The thread diameter of the candles was reduced from 14 mm to 12 mm. The pistons have increased overall height, the height of the fire zone and the length of the skirt. However, the total mass remained the same. The engine remained “plug-inless”, with recesses in the pistons.

Nice additions
In addition to technical advantages, Lada Granta has some attractive portions. The car is equipped with central locking and has security alarm functions. The manufacturer took care of installing remote control for locks and trunk. Now, to open or close doors, you do not need to perform unnecessary actions. This can be done using a special remote control.
The on-board computer belongs to the standard class and has a minimum set of functions. However, the car has a built-in audio system. Thanks to proper insulation and sealing of the body, the interior is distinguished by high-quality acoustics. This allows the driver to save on upgrading the audio platform and allows the driver to effectively use the climate control system.
In a relatively short period of existence, the Grante managed to become a people's car. This is a car that won't break the bank and at the same time will help you get a vehicle that is adapted to daily use. The car comes with medium ground clearance, which makes it invulnerable to the harsh conditions of Russian roads. This is a machine that is easy to maintain and prepared for long-term use.
