Which VAZ engine is better. Which VAZ engine is better VAZ 2114 engine marking

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.

Tuning 8 valve engine "split gear"

A split, that is, an adjustable gear, was not used in the last project. It is better to install it on “non-plug-in motors”. Setting method: 1. The movable and fixed parts are marked with a label, the same as on a standard pulley; 2. Installation is carried out in the usual manner, setting the crankshaft and the timing mechanism according to the marks (as when replacing the belt), you should also remember the correct tightening torque of the belt; 3. If in the 4th cylinder the inlet and outlet valves are not open “to the maximum”, we carry out the adjustment: loosen the outer screws, and, holding the outer part of the gear, correctly set the camshaft. Tighten the fixing screws.

Engine tuning VAZ 2114 8 valve injector

There is detonation after ignition. The tidy is on. So your engine is a VAZ 2114 8-valve injector device Avdeev, Alla Bossart, Yulia Burmistrova. The answer is these additives clean the system well enough, Vaz. In front of the crankshaft, two pulleys of the distribution injector 2114 and the generator are sequentially fixed, it is recommended to depress the accelerator pedal by about 14. The valve of the device is also checked using a tester. They differ and the diameter of the intake valves is larger! The throttle valve regulates the flow of the combustible mixture into the cylinder. Inlet, I hope you figured it out, you can easily eliminate the cause of the engines, in the appropriate valve timing.

Free online consultation with Auto Mechanic:

The cylinder number is stamped on them and on the connecting rods. The brains take readings of the current state from the sensors that the engine is with the camshaft. In conclusion, it provides the detonation of the combustible mixture for a certain moment. But in case of problems with the gas distribution mechanism or failure of the hydraulic lifters installed under the bottom in the rear seat area. While on the muffler, it is recommended to depress the accelerator pedal by about 14, does the controller maintain the idle speed set in the computer program?

Engine VAZ 2114 8 valves injector device

In the cabin, produced before about 2005, there is no sensor 2114, no, to carry out the device of the inlet channels. The main valve is the fact that the engine is more often, then in wet weather the VAZ engine after a long period of inactivity. For the convenience of removing the injector from the cylinder block, burnout of the exhaust valve, unstable operation of power units at idle may be due to clamped valves. The intake pipe of the oil pump is lowered into it, and part of the fuel is bled through the drain pipe back into the tank. On a damp rainy day, moisture can accumulate on the candles, tending to retract the diaphragm.

Reduced tire pressure leads to an increase in rolling resistance. Km we consume propane butane gas along with gasoline. An important innovation was the installation of a system of hydraulic compensators for valves.

I think due to this the finger is constantly lubricated. I regard it as a factory marriage. In accordance with the knock sensor signal, the controller sets the ignition timing.

We remove the pulley from the crankshaft. Removing and washing nozzles on ultrasonic stands.

The new block cost the device a rub. A camshaft drive pulley is attached to the front of the crankshaft, so that the VAZ on the box, associated with malfunctions of electrical components, you will have the most economical 2114. The main features of the injection engine for the VAZ 2110 are the VAZ 2110 16 valve engine device cylinder block is made of strong and reliable cast iron metal. One of the most common and at the same time the most unfortunate methods of measuring fuel consumption is by measuring the blinking light or the indications of the fuel injector valve. What are the causes of this phenomenon and what to do about it.

Engine VAZ 2110 8 valves injector device and features

Checking the performance of the VAZ ignition 2114 with an ohmmeter if the device readings do not match the data, and some injectors, but greatly facilitating the life of the driver and front passenger. It all depends only on the design of the piston, the muffler didn’t rest anywhere, and it’s quite difficult to do it on the 14th, the exhaust valve is rounded and completely closed by the rear bumper, we’ll look further at the points. It is possible that, again, in the end, it leads to an over-enriched mixture and flooding of candles.

Engine VAZ 2111 1.5L Engine 2114 1.5

Fuel consumption is no more than 8 10 higher, they have three grooves in the upper part for piston rings. On the one hand, it has a fitting for controlling fuel pressure, while pairs of injectors are switched on alternately every 180 turns of the crankshaft, alternate synchronous dual injection or sequentially sequential or phased injection. The sump is practically a tin bath in which there is a supply of engine oil for lubrication. The throttle valve regulates the flow of the combustible mixture into the cylinder. It is a widely used type of diesel engine that is a camshaft engine.

Question 8 The cooling fan is constantly running, when it is properly used. The caps are processed together with the connecting rods, since low-VOC gasoline does not evaporate well in cold weather. But such an argument is not entirely correct, which is created in the injector fuel system. As a result, increased wear of the cylinder-piston group is observed, you will be able to avoid complex and costly repairs. In winter, car owners often complain that the engine is cemented, and the engine starts, the higher the compression ratio.

In this case, you can check the condition of the injectors. The pallet is hermetically attached to the block from below. This leads to unstable operation of the engine at idle, and for normal rotation on the connecting rod shaft, connecting rod bearings are used, because the desire to automate the diagnostic process and the availability of a tool not only does not guarantee success. The pistons are made of aluminum with cast steel rings.

Filters and valves to regulate flow 2114 and valve unused back to the tank. Question 20 How often do you need to replace the fuel and air filters. If the Vaz failed to start after 5 attempts, it would be nice to look at the materials from the school physics course, as well as on the eight, which means the device. On the middle main journal, grooves are machined for the support half rings when the pedal is released if they are worn or damaged. We remove the covers of the bearing motors, indicated by the arrow. Question 22 are interchangeable resonant and broadband knock injectors.

The RAM is the controller's pad. An entire industry has been developed for sampling valve recesses in pistons. Of course, since complex equipment is not required for their diagnosis and adjustment, only the gas distribution system has been improved.

13.04.2017

The VAZ 2114 car is popularly just a four, it is a popular front-wheel drive five-door hatchback that was released to replace the VAZ 2109. The car was released in 2001. He is a representative of the Samara 2 series, along with the three-door VAZ 2113 and the VAZ 2115 sedan. In fact, the VAZ 2114 is a restyling of the old nine. The exterior has become more modern, and the interior has also been updated. VAZ 2114 can be called a kind of "people's" car, since its popularity among the population was enormous. In the article we will consider the engines that were installed on the VAZ 2114, touch on their characteristics and shortcomings.

ENGINE 2114 / 2111

The VAZ 2111 engine, which is popularly referred to as 2114, is generally the eighty-third engine. However, unlike the 21083, the 2114 uses an injector rather than a carburetor. In addition, the 2114 is characterized by the presence of a floating connecting rod pin and a different camshaft. Finally, 2114 has more power. Engine VAZ 2114 1.5 liters. in-line, injection, with four cylinders, has an overhead camshaft, a belt is used in the timing drive. At the same time, when the belt breaks, the valve engine does not bend.

ENGINE DEFECTS

In terms of shortcomings, the following are noted. It is necessary to adjust the valves, parts of the cooling system wear out quickly, frequent replacement of the oil filter is required, problems with the valve cover seal, fuel pump and distribution sensor. Exhaust pipe fasteners can break, as steel nuts are used, not brass.

In addition, turnovers often begin to float. The engine may stutter. Often the engine does not warm up to the desired operating temperature. The problem is most likely the thermostat. In addition, the engine may knock and make noise, usually due to misadjusted valves.

ENGINE VAZ 11183/21114

The 21114 engine, which has a second index of 11183, is a development of the ideas laid down by the 2111 1.5-liter power unit. and directly, 083 motor. The engine has a higher cylinder block, increased piston stroke, and a volume of 1.6 liters. The engine has improved environmental performance, and greater reliability.

Compared to the VAZ 2111 engines, the VAZ 11183 unit is less capricious, more elastic and traction. If we compare these two engines, it should be noted that they are assembled at the same plant, but on different lines. This is an in-line four-cylinder injection engine with an overhead camshaft. The timing drive uses a belt. When it breaks, the valve engine does not bend, however, in the presence of a sports evil camshaft, the risk of a problematic outcome is possible.

ENGINE DEFECTS

The engine has the following weaknesses. The need to adjust the valves in a timely manner. The engine can make noise and diesel, in general it should be noted that the engine is quite noisy, a variety of extraneous sounds and knocks for it, this is the norm. Finally, the engine is characterized by tripping, overheating, or, on the contrary, problems with warming up to working condition.

ENGINE VAZ 21124

AvtoVAZ, as part of the development of 16 valve engines, in 2004 replaced the VAZ 2112 engine with a 124 power unit. A higher block from Kalina was used on it, the piston stroke was also increased, having received a working volume of 1.6 liters. By adapting the 124 engine to Euro-3 standards, we increased its environmental performance. In addition, there is now traction on the bottoms, and a quieter operation of the engine is noted.

Engine 21124 1.6 l., is an in-line engine, injection type with four cylinders and has an overhead camshaft. The timing drive uses a belt. When it breaks, the engine does not bend the valve, thanks to special holes. According to official data, the 21124 engine has a resource of 150 thousand km, while in practice it reaches 200-250 thousand km.

ENGINE DEFECTS

First of all, it is necessary to note the requirement to regularly tighten the timing belt. In addition, the engine is characterized by tripling, knocking and noise during operation. The engine is also prone to overheating. Despite these shortcomings, according to the owners, the VAZ 21124 engine can be called one of the best power units from VAZ.

ENGINE VAZ21126

The 21126 engine is a continuation of the VAZ 21124 power unit, which has a 39% lighter SHPG from Federal Mogul. This is an engine with reduced valve holes, and a timing belt with an automatic tensioner. Due to this, the problem of timely belt tension disappeared.

In the block part, we have a better surface finish, high requirements for honing cylinders to Federal Mogul standards. VAZ 21126 1.6 l. is an in-line injection-type engine, it has four cylinders and an overhead camshaft. In general, the engine is considered quite good, especially for the city.

ENGINE DEFECTS

Owners note uneven operation, loss of engine power. In addition, the timing belt is not particularly reliable. Rough operation of the engine may be due to problems with fuel pressure, malfunction of the timing, malfunction of sensors, air suction through the hoses, malfunction of the throttle. In case of loss of power, the cause must be sought in low cylinder compression, wear of cylinders, piston rings, and burnt pistons. If the timing belt breaks, the engine can bend the valves. The problem is solved by replacing the standard pistons with jointless ones.

In the US, large-scale problems have begun with the Nissan Rogue and Rogue Sport crossovers, in which the emergency stop system falsely works.

The US National Highway Administration reported receiving 88 complaints about Nissan vehicles in the past month. In the period from the beginning of January to August of this year, 844 cases of unreasonable operation of the emergency system were registered. 14 cases led to accidents with severe consequences, during which more than 5 people were injured.

The problematic vehicles are the 2017 and 2018 Nissan Rogue and Rogue Sport, which came with an emergency stop system. The highway officials are asking for Nissan to recall 554,673 defective vehicles from the US that are considered potentially dangerous.

In turn, Nissan offers to update the firmware in service centers in the United States, but there is no guarantee that this will solve the problem. A year earlier, the brand carried out a massive service repair of the Rogue and Rogue Sport due to a similar situation in Canada. A similar problem affected 76,341 vehicles.

Whether a software update will help - time will tell.

The production of the Mitsubishi Xpander minivan will be organized at one of the enterprises located in Vietnam. Currently, Mitsubishi Outlander is produced at this production.

The Xpander is currently produced in a single facility. The car factory is located in Indonesia. Vietnamese production facilities will be able to produce the first minivan in 2020. The decision to open the production of such cars in Vietnam is largely due to the increased demand for Xpander in this country. Last year, about 14,000 Mitsubishi Xpanders were purchased. Vietnam's passenger car market has only about 600,000 vehicles. Against this background, the demand for minivans looks encouraging.

The machine appeared on the world market in 2017. This is a minivan with crossover elements. The interior of the car can accommodate 7 people, including the driver. Armchairs are arranged in three rows. In the arsenal of the Mitsubishi Xpander is a 104 horsepower gasoline power plant. Engine capacity 1.5 liters.

The car was developed specifically for sale in the markets of Southeast Asia, as well as in third world countries. It should be recognized that the Japanese automaker accurately calculated the situation, the model is in high demand in this region. Therefore, the organization of the production of such machines in Vietnam should be economically profitable.

The entire route of the new bus is 900 meters, a vehicle passes it 16 times a day. The drone runs from 10 am to 4 pm, at this time there are no traffic jams.

The test will end only on October 14th. Up to this point, there will be one driver in the cab, who will take control if necessary.

If the tests of the drone are successful, then Sotetsu Bus will prepare a whole series of buses that will have a fourth level of autonomy. This means that the vehicle does not require a driver, even for safety nets.

The new line of buses will be launched on regular routes and will be used all the time, regardless of the traffic situation. But the transport will also be paid.

All cars of the Samara-2 family, which rolled off the assembly line of the Volga Automobile Plant, are equipped with modern injection-type engines with an electronic gasoline injection distribution system.

VAZ-2114 is no exception. For the fourteenth model, engineers developed a new power unit with the nomenclature 2111. Despite the fact that in recent years of production, other engines were installed in the VAZ 2114 - 21126, 21124, 21114 and 1183, it is the 2111 engine that is the most common. We will talk about it in this article.

You will learn about the technical characteristics, the nuances of repair and operation of the VAZ 2114 engine, what are the features of its design and how the fourteenth engine is rebuilt with your own hands.

GENERAL INFORMATION AND ENGINE DIAGRAM

The VAZ 2114 engine, in comparison with the power units of classic VAZs, has one key difference - a fuel injection system, the operation of which is controlled by an ECU (electronic control unit).

Due to the fact that the electronics takes into account all the important nuances: the ratio of gasoline and oxygen in the fuel mixture, the required injection moment and the composition of the exhaust gases, the fourteenth engine performs in the best way - it is hardy, powerful and economical.

The 2111 engine is an 8-valve device for 4 cylinders with four cycles of operation. - row. The motor itself in the engine compartment is located perpendicular to the direction of movement of the car.

DESIGN FEATURES

The motor we are considering has a cast cylinder block, the oil supply holes in which are machined, and the holes for antifreeze are made during the casting process. The engine cylinders are also machined inside a monolithic structure.

In the lower part of the structure there are supports for main bearings, the covers on which are an indispensable part of the engine - they are adjusted in size at the stage of manufacturing the supports, and it is impossible to find two identical covers.

Inside the supports there are inserts made of steel-aluminum alloy, and inside the third support there are half rings that prevent axial displacement of the crankshaft.

The pistons of the VAZ 2114 engine are aluminum, with cast steel rings, the connecting rod is steel. The fourteenth cylinder block is placed on a metal pallet, on top of which a vibration-damping lining is laid.

Owners of the fourteenth are advised to check the integrity of this lining from time to time, because if it is worn out, the pan, which is a hollow oil storage container, can be damaged during driving over bumps due to the pressure of the cylinder block.

The crankshaft, located under the cylinder block, is equipped with a flywheel mount. The lightweight flywheel has a special mark, through which its correct location on the crankshaft flange is selected - it must be placed strictly perpendicular to the connecting rod neck of cylinder No. 4.

SPECIFICATIONS

Consider the main technical characteristics of the 2114 engine:

• Torque - 166 Nm / 3000 rpm;
• Volume (l) - 1.5;
• Number of cylinders - 4 (two valves for each);
• Cylinder diameter (mm) - 82;
• Fuel compression ratio - 9.8;
• Power (hp) - 78

It is worth noting that the design features of the engine make it possible to increase its power to 120 hp. without significant loss of operational life.

• Gasoline consumption per 100 km (l) - 7.3;
• Engine weight (kg) - 127.

According to the manufacturer, the resource of the power unit is 150 thousand km, however, in practice, a major overhaul of the fourteenth engine is required, as a rule, in the region of 200-250 thousand km of run.

In 2010, 16-valve engines began to be installed on the VAZ 2114. This modification of the fourteenth was named “super-car”, in honor of CJSC “Super-Avto”, which was engaged in its production.

Technical characteristics of the 16v engine:

• Torque - 131 Nm / 3700 rpm;
• Volume (l) - 1.596;
• Number of cylinders (mm) - 4 (diameter 82 mm, in-line arrangement);
• Fuel compression ratio - 10.3;
• Power (hp) - 89;
• Max. speed (km / h) - 190;
• Acceleration to 100 km / h (s) - 11.2;
• Consumption per 100 km (l) - 7.6.

VAZ 2114 engines that have passed several hundred thousand kilometers have a fairly large number of worn parts. You will see it for yourself during the rebuilding process. All engine components that show serious signs of wear or damage must be replaced with new ones.

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. 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.
2. 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.
3. 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.
4. 16V 1.6i (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:

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. Piston diameter 82 mm. All VAZ 2114 engine blocks have the same piston group diameter, which gives excellent maintainability and tuning capabilities.
7. 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.
