Tuning Engine VAZ 2114 8 Valve Injector

There is a detonation later ignition. The tidy is burning means your engine VAZ 2114 8 valves injector Avdeev's device, Alla Bossert, Yulia Burmistrov. Answer These additives are well cleaned by the system, VAZ. In front of crankshaft Vale Two pullees of the injector of the distribution 2114 and the generator are consistently fixed, it is recommended to squeeze about 14 accelerator pedal. Valve check device is also carried out using a tester. They differ in the inlet valve diameter! The throttle valve adjusts the flow of a combustible mixture into the cylinder. Impust, I hope figured out, you can easily eliminate the cause of the engines into the appropriate gas distribution phase.

Free online consultation with auto mechanic:

On rods, the cylinder number is stamped. Brains take the current status from sensors that the engine with switchgear. In conclusion, it provides a detonation of a combustible mixture of a certain point. But in case of problems with the gas distribution mechanism or failure of hydrocomathers installed under the bottom in the area rear seat. While on the silencer, it is recommended to squeeze about 14 accelerator pedal, the controller supports the idle speed specified in the computer program?

Engine VAZ 2114 8 Valves Injector Device

In the cabin released by about 2005, the sensor 2114 is absent, is missing, carrying out the intake channels. The main valve is the fact that the engine is more often, then in crude weather VAZ engine after long downtime. For the convenience of extracting the injector from the cylinder block, the loop of the exhaust valve, the unstable operation of power units on idling Maybe because of clamping valves. It is lowered by the intake oil pump nozzle, and part of the fuel is flushed through the drain pipe back to the tank. In a raw rainy day, moisture can accumulate in the candlelight, seeks to draw a diaphragm.

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

I think, due to this, the finger is constantly lubricated. Regarding as a factory marriage. In accordance with the detonation sensor signal, the controller sets the ignition advance angle.

Remove the pulley from the crankshaft. Removal and flushing nozzles on ultrasound stands.

The new block cost the device rubles. To the front of the crankshaft, the pulley of the camshaft drive is mounted that the VAZ on the box-related electrical components, you will have the most economical 2114. The main features of the injection engine for VAZ 2110 are VAZ 2110 16 valve engine The device block of cylinders is made of strong and extrute metal cast iron. One of the most common and at the same time of the most unsuccessful methods for measuring fuel consumption is a measurement of a light bulb or fuel valve injector testimony. What are the reasons for this phenomenon and what to do about it.

Engine VAZ 2110 8 Valves Injector Device and features

Checking the ignition melting ignition module 2114 If the reading device does not correspond to the data, and some injectors, but hardly facilitating the life of the driver and the front passenger. It all depends only on the design of the piston, the silencer did not rest on and to do it on the 14th rather difficult valve exhaust pipe Rounded and completely closed with rear bumper, consider further on points. It is possible that again in the end leads to a re-entered mixture and pouring candles.

Engine VAZ 2111 1.5l Engine 2114 1.5

Fuel consumption above no more than 8 10, have three grooves at the top under piston rings. On the one hand, it has a fitting to control the pressure of the fuel, while the pairs of nozzles turn on alternately every 180 crankshaft turn alimony synchronous dual injection or sequentially sequential or phased injection. Pallet is a practically tin bath in which the stock is located motor oil For lubrication. The throttle valve adjusts the flow of a combustible mixture into the cylinder. This is widely used type. diesel enginethat engine with a camshaft.

Question 8 constantly works the cooling fan, when it is properly operation. The covers are processed with connecting rods, since gasoline with a reduced content of volatile fractions is evaporated poorly. But such an argument is not entirely correct, which is created in the fuel system of the injector. As a result, there is an elevated wear of the cylindrophone group, you will be able to avoid complex and expensive repairs. In winter, car owners often complain about whether the engine is launched, and the engine is launched, the higher the compression ratio.

In this case, you can check the status of the nozzles. The pallet is hermetically attached to the block below. This leads to an unstable operation of the engine at idle, and for normal rotation on the shaft of the rods serve skeeping insertsTherefore, the desire to automate the diagnostic process and the presence of the tool not only does not guarantee success. The pistons are made of aluminum with the steel rings flooded in them.

Filters and valves for adjusting the feed 2114 and valve unused back to the tank. Question 20 How often it is required to replace the filters of fuel and air. If the VAZ failed to run after 5 attempts, it would be nice to see the materials from the school course of physics, as well as on the eight, and therefore the device. On the middle indigenous neck, the grooves are sharpened for the reference semi-colts, when the pedal is released if they are worn or damaged. Remove the lids of the bearing engines specified by the arrow. Question 22 Interchangeable resonance and broadband detonation injectors.

The operational storage device is a notepad of the controller. The whole industry was developed on the sample of recesses under the valves in the pistons. Of course, since the complex equipment is not required for their diagnostics and settings, only the gas distribution mechanism system is improved.

If during the operation of the car engine, there are interruptions regularly, and the sound coming out of the exhaust pipe is more like a tractor growl, it says that your motor troit. This problem You need to decide, and promptly.

The main causes of trimming

If you say that you have a troit engine, many will answer - the cylinder does not work. But such an argument is not quite correct, since the cylinder ceases to work properly. However, there may be several reasons for any:

• Compression in the cylinders is too low;
• Ignition Candle faulty or partially does not fulfill its functions;
• The valves are poorly adjacent due to a long lack of adjustment;
• Nozzles contaminated or transfused, therefore need to be replaced;
• The oxygen sensor stopped functioning;
• Candle high-voltage wire got damage;
• The ignition coil is faulty;
• DPKV does not work (crankshaft position sensor);
• I broke the computer (electronic control unit);
• The timing belt flew or just jumped into several links;
• The air filter failed or contaminated.

Some problems literally immediately manifest itself in the form of a pretext of the cylinder, but others can show themselves only after a while. And this is the most unwanted event development scenario.

Primary signs of problems that can inform about the cylinder breakage, such:

1. Vibration rises, since the rhythm of the valves and the other rotating gearbox parts and power aggregate broken.
2. Fuel consumption increases significantly, because the injection system stopped working properly.
3. From the exhaust pipe comes an unpleasant characteristic smell, which is explained high levels Concentration of harmful impurities and unburned fuel.
4. The power of the power unit decreases noticeably, which negatively affects the dynamics and maneuverability of the car.

If you have noticed that the engine troit, but did not take any measures, it threatens you soon a full way out of the engine, to repair which may be impossible. When the injection of the injection 8 valve engine on the VAZ 2114, in a non-working cylinder constantly comes fuel. It does not burn, but mixed with butter, then turns into the crankcase. If the process continues for a long time, the oil loses viscosity, ceases to perform the role of lubricant, the parts operate on the limit loads, the metal turns into a chips. There is nothing good in this, let's say frankly.

What to do?

There are a number of events that are recommended when detected that the engine is troit. All will allow you to answer certain questions. Therefore, prepare to highlight a lot of time to your car.

The first thing you want to do is to determine the pretext of the cylinder. He is not alone there. For this you need:

1. Open the hood by running the engine at the same time;
2. Listen and remember the sound that now emits your motor;
3. In turn, remove the wires with the candles. If you remove the high-voltage wire, the sound must change. If, when removing the next high-voltage, the sound did not change, congratulations, you found a defective cylinder.

Now dismantle the problem candle and check it for functionality. To do this you need special keydesigned specifically for removal of spark plugs:

1. Pay attention to the electrode. If it is clean, the whole, but on the head a lot of gary is most likely in the combustion chamber there are a large amount of dust. This speaks of a malfunction air filter in the air supply system;
2. If the GAR is present on the head and the electrode, which is noticeably burned, the mixture comes up poor, the combustion occurs with premature ignition;
3. If the head is in Gary, but the electrode is intact, the mixture was rich, and the ignition was submitted late;
4. Check the presence of spark. If it is, then the problem needs to look next. When there is no spark, it is recommended to replace it with a new one and check the engine performance with a new candle.

If your car with a fairly impressive mileage, to identify the causes of "Troji", it is recommended to perform the following operations:

1. Replace the ignition candles;
2. Remove old high-voltages and change them to new, high-quality. Sometimes banal microcracks on them lead to breakdowns and failure of the entire power unit;
3. Measure compression in a cylinder that does not work. When identifying violations, you may define that the valve or problem in the rings are burned;
4. Perform valve adjustment. In general, this procedure is carried out with a periodicity of 15-20 thousand kilometers in order to prevent;
5. Check if the ignition coil works. A common problem for VAZ 2114. Trying to repair it is not worth it, it is better to immediately change to a new one. It will not be worth a lot of money;
6. Replace the old air filter to a new similar unit;
7. Check if the timing belt is installed and functions.

If even these events did not give any result, we advise you to try out a few more effective methods Engine Recovery Recovery:

1. Check out electronic block Control. When problems are detected, immediately change the old electronic control unit to the new one;
2. Check the functionality of the system responsible for fuel supply. In some cases, you have to get to the nozzles;
3. Analyze the operation of the oxygen sensor. It is subject to repair, but it will be better to immediately replace the device;
4. Make sure the crankshaft position sensor is working. This is determined using the electronic control unit. It will give an error that indicates the presence of a malfunction. When problems with the sensor, there is nothing else, except to change it to a new one.

What to do if troit at idle

There is also a fairly common situation, the causes of which there is a total of three.

1. There were problems with fuel supply. Need to rinse fuel system And clean the nozzles ultrasound.
2. There was a malfunction in the ignition system. In such a situation, it is recommended to change the spark plugs, check the performance of the ignition coil, as well as install a new set of high-voltage wires.
3. Valves are not adjusted properly. You will need to adjust the valves. If the situation requires more cardinal measures, then the valves will have to change.

Situations when the engine troit is found in a huge amount of cars. The model of the domestic manufacturer AvtoVAZ in the face of the VAZ 2114 is no exception. This is not a sentence to your engine. Just need to quickly take appropriate measures.

If you intervene in the work of the unit at the very first signs of "Trojas", you will be able to avoid complex and expensive repairs. But when the situation is started on Samotek and check the node is postponed from day to day for later, get ready to spend huge money soon or look at all new engine To replace the old.

On cars of the "Samara 2" series, the Volga Automobile Plant set injector engines With electronic, distributed fuel injection. And for VAZ 2114, which appeared in 2001, and in the series was launched in 2003, such power point - Model 2111. In subsequent years, various modifications of this car were produced and some of them were made by other models of engines, such as - 21114, 11183, 21124 and 21126. But the most mass serial machines were VAZ 2114 with models 2111 and 11183.

Engine design VAZ 2114

The main thing distinctive feature All models of engines on the VAZ 2114 is that the injector is installed on them. Electronic fuel injection control Depending on the readings of a large number of different sensors controlling a variety of parameters, up to the composition exhaust gasesOf course it contributes to the balanced and economical engine operation. The engine itself on the VAZ 2114 is an inline, four-stroke, an eight-flaped unit, in which the camshaft is located on top. It has four cylinders, works on gasoline and cooled special fluid. In the motor compartment of the car, the motor is located transversely movement. The photo of the VAZ 2114 engine shows its real location relative to other aggregates. Cylinder block This power unit is made of cast iron by casting. All the holes for antifreeze are formed in the casting form, oil is sharpened by mechanical method. Workers cylinders are also pulled out. At the bottom of the block there are supports of native bearings, the covers are made to them in the manufacture of the block, they have an individual fit, so they cannot be replaced. When disassembling it is necessary to pay attention to the labeling of these covers so as not to confuse. In the covers and supports inserted liners made of alloy steel and aluminum. In the third support persistent semiring, which prevent the axial movement of the crankshaft.

Pistons Made from aluminum with steel rings flooded in them. Flashing fingers, and rods forged from steel. On the bottom, the cylinder block closes the pallet, the gasket must be between them. It is necessary to follow it for its integrity, because the pallet is a coolant for the engine oil, which during the operation of the engine, luxuries all rubber parts. The lubricating oil system operates under pressure and by splashing. Pressure is created by the oil pump, which, taking the lubricant from the pallet, drives it through the direct-flow oil filter. It has a return valve that does not allow oil to flock back into the pallet. At the crankshaftLocated at the bottom of the cylinder block, there is a flange. A flywheel is attached to this flange. On the flywheel drilling, a special installation label is made for the correct location of it on the crankshaft flange. This label should be located opposite the cervix of the fourth cylinder rod. From the left side of the Cylinder Block, the PCA is installed, which is also called the coolant pump. Block head, or GBC, made of aluminum. The valve with sleeves and saddles and pushers with adjustment washers are located in the CCC. Camshaft It is located in the GBC on top and clamped the bearings to which bearings are pressed. CHBC closes with a lid with a neck for oil pouring. Camshaft and pump The belt from the crankshaft gear pulley is given. Nearby is another belt that spins the generator.

During the operation of the ICT, various failures and malfunctions can occur on the car. independent repairs or with the involvement of specialists. The need for overhaul of the power motor installation, during its proper operation, occurs when 150,000 km of mileage is achieved. In this case, you need a bulkhead of the engine VAZ 2114.

1 . Before proceeding with the disassembly of the engine, it is necessary to drain the oil and coolant, and then wash the entire unit. Be sure to remove all hinged equipmentnot to damage it when bulkhead. 2 . Disconnect all tubes through which gasoline is supplied. 3 . Remove all systems and nodes associated with air supply, remove air supplies and discharge hoses and nozzles. 4 . Remove the cooling system and Carter Sapun pipes. Do not forget to disconnect the throttle nozzle. 5 . Remove the receiver, as well as the bracket of fastening pipelines and fuel ramp, pull out the nozzles with the regulators. 6 . Remove the wires with the ignition module and the detonation sensor. Unscrew the ignition candles. After that, unscrew all the sensors. 7 . Remove the generator, removing the tension strap. With the generator to shoot all brackets and planks necessary for its installation and adjustment. 8 . Block the flywheel and remove the pulley of the generator. 9 . Remove the camshaft drive with a lid, tension mechanism and pulley. 10 . Unscrew the pump, remove the exhaust manifold and thermostat. 11 . Disconnect the oil filter and oil crankcase, then pull out the oil pump. 12 . In order to remove the piston group, you must unscrew the nuts from connecting rod bolts and remove the cover. 13 . As the flywheel is blocked, you need to unscrew the fastenings of it with the flange and remove the handwheel disk. 14 . Remove the covers with native bearings along with the bottom liners. 15 . Gently pull out crankshaft. You need to handle it very carefully to prevent damage and scratches. 16 . Remove the upper liners and stubborn semirings.

When bulkhead, the engine is required to carefully examine each unit, node or part. When mechanical damage is detected, the parts is subject to mandatory replacement. Also replace all gaskets, washers and non-metallic parts.

The overhaul of the power unit will require more in-depth knowledge in the design and principle of engine operation, but if desired, each motorist is able to figure it out and carry out these operations with their own hands.

It is worth noting that when diagnosing faults, it is worth carefully and carefully examined each item for the presence of defects. The 8-valve injector engine VAZ-2114 is sufficiently similar to the first generations of this motor - Samara. Of course, the designers made many changes in the particular power unit, but in many respects they remained similar. Repair and service this engine It must be carried out regularly, which will extend not only its resource, but also reduce the wear of parts that are located inside.

Sensors VAZ 2114.

Modern car with an injection engine is a complex mechanism that is a combination of numerous aggregates and electronic devices. The management of them is carried out using different sensors. In order to use them competently, you need to know where and what sensors are on the VAZ 2114. Sensors are set to signal the state of systems, the level of liquids, emergency situations. They are located on the engine units, transmission, body and in electronic circuits. Almost all VAZ 2114 sensors are installed on serial machines. However, some can be supplied by a car owner independently or during tuning machine, as an additional option. List of basic measuring devices placed on serial VAZ 2114, this is a sensor: ➤ oil pressure; ➤ Tosola temperatures; ➤ Tosol levels; ➤ fuel levels; ➤ idle; ➤ mass flow of air; ➤ liquid level in brake system; ➤ The position of the throttle of the choke; ➤ speed; ➤ crankshaft positions; ➤ camshaft positions, it is a phase sensor; ➤ oxygen; ➤ detonation; ➤ uneven road; ➤ ambient temperatures. The list is quite solid, but the car owners do not calm down and improve their cars by setting additional devices. As options, it is most often installed: ➤ Device signaling about open doors; ➤ Ferred wear meter brake shoes; ➤ Light sensor device. Coolant temperature meter. It is also called the engine temperature sensor. The forums often ask the question - where the engine temperature sensor VAZ 2114 is located. It is installed on the inlet plug of the cooling head of the cylinder head. Checking its performance is simple enough. It is enough to connect an ohmmeter to it and omit the DPT into the vessel with the liquid. It should be heated to monitor the temperature and resistance change due to its increase. By matching the desired schedule, the device is considered serviceable. Cooling fluid level sensor - stands in a tosol tank. It is twisted like an ordinary plastic cover, then electrically connected. Level sensor brake fluid - Float type device installed in a tank with brake fluid. The idling sensor, or RXX - is installed on the throttle node next to the throttle of the throttle. The air consumption sensor is placed on the air filter housing near a large inlet. Position sensor throttle valve - Located on the throttle housing. Crankshaft position sensor. It is also called synchronization sensor, due to the fact that the controller according to its testimony synchronizes its work with the injection system. Installed next to the pulley of the generator drive. The camshaft position sensor or phase sensor is located on the side of the air filter next to the cover of the GBC. Depending on the position of the camshaft, it supplies the pulse on the ECU and the injection takes place before the discovery of the valve. The fuel is discouraged simultaneously with the air portion, it is well stirred and high-quality detonation occurs. Oxygen sensor or lambda probe. Stands in the receiving manifold exhaust system In front of the resonator. Gives a signal to an electronic onboard system on the level of oxygen concentration in exhaust gases. The detonation sensor is set between the second and third cylinder on the fan side of the power plant. His readings through the controller affect the ignition advance angle. These are all the main sensors on the VAZ 2114 engine. However, there are other sensors that issue VAZ 2114 testimony indicating its performance or status. ambient or road surface. Fuel Level Meter - placed in the intake chamber fuel tank. The VAZ 2114 establishes a Dut-1-03 sensor. The speed meter - stands on the checkpoint and transmits data on the current speed of the machine to the speedometer. It is also connected with the controller who gets its impulses adjusts work RHX Or the throttle of the throttle, from what position is the gas pedal and what engine turnover is. The lock (sensor) of the uneven road - it is attached under the hood on the body in the area of \u200b\u200bthe right mudguard cup. Reports the change in the body fluctuations to the controller, when the signal level exceeds the electronics signal disables the diagnostics of ignition passages. The temperature sensor overboard (i.e. the surrounding atmosphere) - the regular place of its placement on the VAZ 2114 - in the center behind the front bumper. During the operation of the car, the driver constantly monitors the state of systems and units using instruments, signal lights and on-board computer. The testimony for them goes from the measuring devices that are installed throughout the car, the lives of people in the car can also depend on their correct and clear work. Therefore, it is necessary to monitor their condition and working capacity, paying attention to this during the next one. Signal devices called sensors are set to inform the driver or any control device data on changes occurring during the operation of the vehicle or the status of the corresponding unit or system, as well as to be asked for refusals or emergency conditions in the machine. Therefore, the driver must be good to represent the principle of operation and location of sensors on the VAZ 2114. Oil pressure meter. Important device, Signals a low engine pressure in the engine. When it happens, this indicates problems in motor installation. The most serious of the consequences of ignoring this signal may be overhaul or full replacement Engine. An emergency oil pressure light tied with a sensor lights up in several cases: the oil level has significantly reduced; Oil filter clogged; Oil pump failed; faulty oil pressure sensor; The wiring is faulty or the oil pressure dropped due to the facilities. On an eight-glove engine, the sensor is with right side Below is the valve cover in the block head. On the sixteenth glove - on the left end of the camshaft bearings. The design of DDM is extremely simple, and its price is small, therefore, if it failed, it is cost-to-buy more costly than to repair it.

The volume of the VAZ 2114 engine and its characteristics changed and improved throughout the entire period of release, from 2001 to December 2013. Injector 8-valve aggregates of 1.5 liters were installed on the first batch. After the modernization of 2007, new engines were put on the "fourteenth", 1.6 liters volume. New VAZ-11183-1000260 serial engines received 3 ecology class, EURO-3.

The most powerful of all the aggregates of the VAZ was assembled and installed on Lada Priora in 2010. Power of this power plant amounted to 98 horse power. A shared line of all engines of the VAZ 2114 model is that they are 4-strokes, have the same fuel injection system. In engine cylinders, fuel is served due to the installed nozzles.

Today, this method of the power of the engine is the most effective of all fuel supply schemes. Motors have a standard, prior view, and their camshaft is on top. To cool the aggregates used liquid system Closed type. Part of the mechanisms are lubricated by oil under pressure, part - by spraying the oil.

VAZ 2114 motors characteristics

A very common model of the motor at VAZ 2114 was the engine with a total capacity of 81.6 liters. from. With the serial number of VAZ 21114. This is a row type of power installation using injector system Nutrition. The cylinder block is made of cast iron. The speed of rotation of the power unit reaches 5,200 revolutions per minute. For high-quality operation, the engine is charged with AI-95 gasoline.

Unlike its predecessor (VAZ 2111), in the updated VAZ 21114 due to the installation of an improved crank and increasing the stroke of the piston system, the engine volume increased by 0.1 liters. The total volume of the VAZ 21114 was 1.6 liters. In addition, it became much more powerful. The minus increase in volume was the reduction of torque.

Piston stroke of such a motor on VAZ 2114 reaches 71 mm. The size of the diameter of the cylinder is 82 mm. The engine volume varies from 1499 to 2114 cm³. Torque - 116 Nm / 3000 revolutions per minute. Fuel consumption in the city reaches 8.8 liters, on the track it is significantly lower - 5.7 liters per 100 km. Oil consumption - 50 g / 1000 km. Engine weight 2114 - 127 kg.

The resource of the unit according to the factory data - 150 thousand km., In fact, up to 250 thousand km. Definitely, VAZ 2114 does not suit the adrenalinearians and lovers to drive on the track. This option is perfect for business, self-confident people. The car perfectly cope with the need to carry heavy trailers and so on.

If you wish to have a more high-speed option, it is better to stop your choice on the VAZ 2111 half-and-half-liter motor. The reduced passage of the piston system allows the engine to rotate faster.

Select the number of engine valves

The engine selection depends largely on the number of valves installed. Early models of VAZ 2114 were distinguished by engines with 8 valves. After 2007, motors with heads on 16 valves came to replace the eight-shield engines. Valves engines internal combustion Used for the intake of the fuel-air mixture and exhaust exhaust gases. Accordingly, the higher the bandwidth of the valves, the stronger and more powerful motor.

It is not difficult to conclude that the bandwidth of gases through the head with the 8th valves is much lower than through the 16-valve. Despite the fact that 8-valve engines do not work well at high frequencies, they give excellent performance when low revolutions.

16-valve engine

The engine having 16 valves can miss more gases due to which the car is accelerated faster. Alas, such a design also has disadvantages, the main of which is the deformation of the valve themselves. The 16-valve engines have not yet passed the test of time, so eight-point is still considered more reliable.

When choosing a motor to a VAZ 2114 machine, you need to be guided by the following principles. The 16-valve engine (1.6 L) or 8-valve (1.5 L) is chosen if high speed and high torque is required. When a focus on a stable and powerful rift on low revs optimal option There will be an engine with 8 valves of 1.6 liters.

Causes and repair of motors malfunction

As mentioned, according to AvtoVAZ, the maximum resource of the VAZ 2114 engine is 150 thousand km. With normal and timely maintenance, the motor can work out and more. Standard temperature range - from 95 to 103 ° C. Oil change should be held on the heated engine VAZ 2114 every 10-15 thousand km. When the first signals for a car malfunction must be applied to the station or to find the cause itself. The most common engine problems.

1. Motor floating turnover. As a rule, it happens in new cars and at idle. If the machine without run - go to the diagnosis, the repair must be made under warranty. The causes of the problem can be an idle regulator, a throttle position sensor or a vacuum apparatus.
2. The car's engine stalls on the move (floating motor turns plus problems with the air flow sensor) - the causes of the breakdown.
3. Uneven engine operation (Troit). Cylinder compression should be measured. If in one of them is low compression, the valve or head burned there. If the difference is small, then the pressure should be adjusted in the valves or replace the gasket. If compression measurements did not show deviations, then you need to check the ignition module.
4. The engine does not heat up to normal operating temperature. The reason lies in a faulty thermostat.
5. Noise and tapping in the engine. As a rule, the reason is bad adjustment of the valves. If when you click on the gas pedal, the sounds are enhanced, you need to go to those skilled in the art. Problems may occur in rod bearings or crankshafts either in pistons of cylinders.

On the cars of the Samara 2 series, the Volga Automobile Plant established injector engines with electronic, distributed fuel injection. And for the VAZ 2114, which appeared in 2001, and in the series was launched in 2003, such a power plant was developed - model 2111. In subsequent years, various modifications of this car were produced and other models of engines were put on some of them, such as - 21114, 11183, 21124 and 21126. But the most mass serial machines were VAZ 2114 with models 2111 and 11183 models.

Engine tuning theory

The concepts of "engine tuning" and "budget tuning" are incompatible, so I almost have nothing to say. Of course, the most effective measure in the tuning of the motor is an increase in the working volume. Only this gives a simultaneous increase in power, torque in the entire turn range - from a modified VAZ-2112 motor with a volume of 1.8l. You can get a torque of more than 20 kg / m, and the maximum craving 10 kg / m standard motor 2110 is already curled from 1500 Min! Another measure is the installation of various types of compressors, fuel replacement on a more "fuel" (nitrometanol, i.e. alcohol), feeding the additional oxidizing agent of fuel (nitros), but it is expensive. And even then a little, what can be done with the help of reasonable investments, requires the hands of the master and greater experience. Therefore, I cook here not only the motor itself, but also the system of food, ignition and release. GRM - The gas distribution mechanism is the only budget tuning available place where the "Raising" can be learned. Theory. The camshaft determines the lifting of the valves (and the greater, the better - in the entire range of motor turns), as well as the time and duration of the valve opening. Unfortunately, we cannot raise the valve as much as it wanted: the valve springs will choose the gaps between the turns and break. To raise the valve even higher, refinement of the CCC is required - first - to lower the valve seat (for example, for MM54 - by 1 mm), then more radical measures - replacement of springs, pushers, etc. - not budget. Therefore, for the motor 2108-2111, the maximum allowable lifting of the valves is 9.7 mm, i.e. Without alteration, the timing can be put in camshaft "", "needy" or their analogue.

A few words about the time and duration of the opening of the valves - the width of the phases. The higher the rotation of the motor, the earlier to the top dead point (NMT) You need to open the inlet valve and later close it. It is necessary to provide a mixture having a large inertia on high revolutionsThe ability to fill the cylinder as fully as possible and give the release of the burnt charring. Accordingly, on the release phase, you also need to act with ahead, in order to achieve NMT, when the hot mixture does not work, give it to start exit from the cylinder, as well as delay the exhaust valve open after the NTT to remove the exhaust gases from the cylinder . In small turns, this leads to the fact that not yet to the end of the exhaust gases fall into inlet system, not a launch of a fresh mixture, which reduces cravings on the bottom, makes it very unstable idling (Therefore, on shafts with wide phases, it is necessary to increase idle speeds). On the large turns The overlap of the inlet and output phases allows to provide a more continuous gas flow through the CPG and, accordingly, burn more than the mixture and significantly increase the return of the motor. The dependence is non-linear: a gradual increase in the overlap of the phase first gives an increase in torque at high revs, gradually shifting the maximum for more and higher revs. After some moment, the subsequent increase in the overlap of the phase gives the opposite effect - the drop in power and torque even on high revs. If we are talking about a two-level motor. That is the task of the master - find this position of the shafts, in which we get the maximum torque at the highest possible revs, and thus getting the maximum power. In the case of a single engine, it is not necessary to think about it - the overlapping of the phases is laid by the manufacturer, you only need to accurately set the position of the camshaft relative to the crankshaft, and the overlap can be changed only by changing the shaft. To get a "tractor" craving, a shaft is needed with a minimum phase overlap and the maximum lifting of the valves. We get more traction on low revs, which is very relevant for the city with eternal traffic jams.

Specifications 1.6 liter engine are not particularly different from previous versions. Compared to one and a half years, this engine has become powerful for only 4 hp Apparently the AvtoVAZ designers in pursuit of increasing the resource of the engine completely forgot about what they also need to add power. Therefore, happy car owners themselves are trying to "add horses" under the hood. There are cases when craftsmen managed to squeeze up to 140 hp from the motor VAZ 2114, the engine tuning added the power almost twice as bigger than the factory specifications. But with increasing power, the engine resource decreases. Therefore, we will talk about what methods can increase power and at the same time as weaker can reduce the life of the VAZ 2114 engine.

It's no secret that in your regular one, that is, in serial type, the engine develops far from all the power to which it is capable. You can configure the firmware in a new way, but it will not be possible to change the load curve without reducing the ecology class. You can buy a "racing camshaft" to install it instead of a regular one. But then under the new phases it will be necessary to change the firmware ... Consider what happens if only methods apply affordable tuning. Let's just say, in the Hatchback VAZ-2114, the increase in power can be 20% and even 25%, and we are talking only about 8 valves. You don't have to clean the valve channels. During the tuning, the engine 21114 was refined (1.6 liters). List of works: The boring was taken by the inner diameter, which is equivalent to an increase in the valve;

The neck of the channels also had to crowd out a bit. Thin duralt plates were installed, which made it possible to dissolve the springs by 1.5 mm; The regular valves were replaced by lightweight; Guide sleeves were drawn from a special brass;

The construct has a split gear;

Sugari valves just in case were replaced by import; A shaft with "narrow phases" was installed: the release is 66 degrees, inlet - 70, opening angles - 246 and 250 degrees, respectively. Valve stroke - 9.5 and 9.6 mm. Our new Motor It remained "not inhibited" - the valves do not get to the pistons. When checking on the stand (the sensors were disabled) the result was not impressive.

If you install the engineering firmware, you can choose the parameters "from and to". And then the picture looks better ...

All sensors, including lambda probe, in the latter case were connected. I managed to remove 96 "Forces" at 5,300 rpm!

How not to increase the power of VAZ 2114!

✔ should not try to hold the boring canals. This operation can be performed in the absence of ball milling cutters, but in garage conditions Nothing will happen even with cutters. The essence 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 hatchback VAZ-2114, the increase in power was 24%, and this is without the installation of "chandeliers", "improved exhaust" and other expensive elements. ✔ It makes no sense to buy "racing camshaft" without having a suitable tuning firmware.

How to make the engine tuning VAZ 11183

It is clear that the mandatory stage of the tuning of the motor 11183 will be replaced by the ECU. Everything is simple: the regular block M74 cannot be glued, but "January 7.2" is a good and time-tested solution. It will be necessary to abandon the option "E-gas", and therefore replace the throttle assembly and receiver.

The parts of the intake path were borrowed from the engine 2111. The pedal was installed "under the cable", and the motor began to look like human.

With the controller "January" everything works well, but the regular firmware is not an option if the camshaft was replaced. And he, in turn, possesses the parameters: the width of the release phase - 104; Phase width - 109; The opening angle on the release is 272; Opening angle on the inlet - 268; Valve progress (Issue / inlet) - 9.5 / 10.1 mm. After installing the new shaft, the engine has become "Vtykov". However, on the hatchback 2114, the increase in power is almost always associated with a compromise. In this case, I had to donate reliability. What has improved: the maximum torque increased by 14 N * m; Power also increased - the limit in the "90 Forces" was passed. By the way, any tuning leads to a decrease in durability. Make a choice.

Tuning 8 valve engine "With a split gear"

Cut, that is, the adjustable gear in the last project was not used. It is better to install it on "non-stick engines". Setup method: 1. Movable and still part marked with a label, the same as on a standard pulley; 2. Installation is carried out in the usual manner, exposing the crankshaft and the GDG mechanism by tags (as when replacing the belt), it should be remembered about the right torque of the belt; 3. If in the 4th cylinder of the intake and exhaust valve are not open "at the maximum", we carry out adjustment: weaken the outer screws, and, holding the outer part of the gear, correctly exhibit the camshaft. Tighten the locking screws.
