Body

One of the most popular domestically produced station wagons is the VAZ 2111, a five-seater family car that is perfect not only for city trips, but also for traveling in more extreme conditions.

If we briefly consider the main technical characteristics of the VAZ 2111, then the following points can be distinguished here. The working volume of the injection engine is 1499 cubic meters. cm - for modification 21110 and 1596 cu. cm - for modifications 21112 and 21114 (the indicated model VAZ 21114 has a 16-valve engine, which allows it to reach speeds of up to 185 km / h). Fuel consumption in the urban cycle is about 10.1 l/100 km (average consumption is 7.5 l/100 km). The steering system provides for the presence of a hydraulic booster. The capacity of the fuel tank of all modifications of the VAZ 2111 is 43 liters, like that of the VAZ 2110.

Among the undoubted advantages of the VAZ 2111 are the unusually smooth running of the car, a large trunk, as well as its high stability on almost all types of surfaces. The model is equipped with a powerful heater with automatic temperature control, which guarantees comfortable trips even in the most severe frosts.

The VAZ 2110 (or Lada 110) is a four-door sedan with front-wheel drive and an original design. Serial production of the five-seater Lada 110 began in 1996 and continues to this day (currently the car is assembled under the brand name "Bogdan 2110" at the LuAZ plant in Ukraine). Since 1996, several modifications of the VAZ 2110 have been launched at once, among which you can find models with both 8-valve and 16-valve engines (in later versions). Such technical characteristics of the VAZ 2110 as the type and displacement of the engine (four-cylinder gasoline with a volume of up to 1596 cc), as well as the maximum speed of the Lada VAZ 2110 (170 km / h for an 8-valve engine and more than 180 km / h for a 16- valve engine) make this front-wheel drive sedan ideal for urban use to this day.

Among the distinctive features of the VAZ 2110, which belongs to the upper price segment of LADA cars, one can also note the presence of an immobilizer, a gasoline vapor recovery system and a special onboard control system (diagnostic unit). It was possible to install power windows (they were actually installed), as well as power steering.

Engine VAZ 2110

VAZ 2110 injector 8 valves came to replace the carburetor engine, which was originally installed on the first VAZ-2110. At the same time, an injector 8-valve with a working volume of 1.5 liters first appeared, but then the engine working volume was increased to 1.6 liters. An injector with 8 valves with a volume of 1.5 liters received the VAZ-2111 engine index, a more powerful unit with a volume of 1.6 liters (8-cl.) received the VAZ-21114 index. Recently, modifications of the 21114 engine have been produced; they are installed on almost all today's Lada models, though already under a different index.

Today we will talk about the device of the 8 valve injector VAZ-2110 as well as the characteristics of this power unit. In our photo at the beginning of the article, you can see how the “tens” injection engine looks under the hood of a car. So, how does the VAZ 2110 injector 8 valves work? Firstly, the main difference between the carburetor version of the engine and the injector is the supply of fuel to the combustion chamber. If in a carburetor engine the combustible mixture is sucked into the cylinders under the influence of the vacuum created by the pistons, then in the injection unit the fuel is injected under pressure. It is because of this that the entire design of the fuel system of the injector and the carburetor "ten" is different. It all starts in the gas tank, where an electric fuel pump is installed, the task of which is to create the necessary pressure in the rail. From the rail, pressurized fuel is injected through the injectors into the combustion chamber. The entire injection process is electronically controlled, which opens and closes (by means of a return spring) the injector solenoid valves, injecting fuel into the engine. But the electronics in the VAZ 2110 8-valve injector does not work on its own, but is guided by the signals from pressure sensors in the fuel system, air sensors and throttle position. In the carburetor “top ten” there is none of this. In this regard, let's talk about the pros and cons of the VAZ 2110 injector 8 valves. On the positive side, it can be noted that the operation of the injector is more stable, the engine produces more power, torque, while fuel consumption is less than in the carburetor version. But if the carburetor VAZ 2110 can be repaired with almost bare hands, then the injection version requires diagnostic equipment, without which it can be extremely difficult to identify the problem. After all, if one of the sensors turns out to be faulty, then your injection engine may not start or work intermittently.

Main malfunctions

The main malfunction characteristic of the VAZ 2110 is the appearance of the engine tripping effect. Malfunctions can occur for various reasons. Consider the factors by which unstable engine operation begins, as well as methods of elimination. If the stove does not heat up, look, but about replacing the valves.

Poor quality fuel

The first step is to check how high-quality fuel was poured into the vehicle. If the gasoline was of poor quality, then most likely one of the elements of the fuel system was forgotten. So, the motorist will have to find out what the fuel supply scheme is and find the details that could fail. So, the first element that falls under the gaze is sprayers. Injector malfunctions can cause unstable operation of the motor, which will lead to tripling. A special stand is used to diagnose and clean the assembly, but many motorists carry out the process on their own, using a carburetor cleaning fluid. Also, unstable engine operation can be caused by clogged fuel filters. One is located under the rear right wheel, and the second in the fuel pump. There is a filter mesh on the fuel pump intake that needs to be replaced. The process is quite complicated, since you have to remove the rear seats and remove the fuel supply element. But the fuel filter under the wheel can be changed quickly and without any problems.

Ignition system

Damage to spark plugs or high voltage wires can also cause tripping. So, it is necessary to check all the elements with the help of a tester, as well as inspect them visually. If there is damage, it is recommended to replace the entire set.

Sensors and ECU

Another major cause of engine tripping is the failure of one of the engine sensors, as well as a malfunction in the electronic control unit. To diagnose, you need to connect to the "brains". Further, based on the errors shown, find the faulty meter and replace it. If this does not help, and the error in the ECU remains, then it is recommended to reset, and in some cases, flash the control element.

Maintenance

Maintenance of the motor is carried out every 10-12 thousand kilometers. The map-scheme is available from the official representatives of the manufacturer. But, as practice shows, it all comes down to changing the oil and oil filter.

Many motorists ask the question - what is the best engine oil to fill in a VAZ 2110 8 valve power unit? The best option remains a semi-synthetic motor oil of domestic or foreign production labeled 10W-30 or 10W-40.

Not many motorists can boast of a powerful 2110 engine. So, in order to improve the power characteristics of the engine, it is necessary to carry out chip tuning of the VAZ 2110. To do this, they usually turn to specialists, but more and more vehicle owners who carry out the process on their own.

The chip tuning scheme is quite simple. To carry out the operation yourself, you will need an OBD II (USB-Auto) cable, a laptop computer and software. It is worth remembering that there are three options for finalizing the power unit: for power (but at the same time an increase in consumption), for a decrease in consumption (leads to loss of power) and balanced (balance between the optimal consumption and power indicators).

Usually, chip tuning of the VAZ 2110 is done in order to reduce fuel consumption, therefore, if the owner of the car decided to do it himself, then it is necessary to select the appropriate software. But, it is recommended not to take risks and turn to professionals for help.

Many people are concerned about the question of whether the valve bends on the VAZ 2110 injection engine. No, not oppression. The 8-valve injector does not suffer from this flaw. But this does not mean that you should not follow the timing belt. Since loosening and then jumping the belt a certain number of teeth will lead to inevitable problems. It is worth paying special attention if engine oil gets on the belt, an oiled belt will not last long. Further, a detailed image of the timing diagram of the 8-valve injection engine "dozens". See photo below.

When replacing the timing belt on the VAZ-2110, it is necessary to clearly align the marks on the camshaft and crankshaft pulley, without this the motor will not work normally. Another important point, when the tension roller is moved to its original state, the marks move as the belt tension changes. Therefore, carefully check whether the timing marks are clearly aligned before putting on the casing covering the timing belt.

Transmission and suspension VAZ 2110 8 valves injector

The Lada 21102 has a built-in five-speed manual gearbox (manual transmission). This box is used on all versions of the 2110 line. It has good sound insulation, the lever travel is comfortable, the switching smoothness is much better than that of Zhiguli and Samara. The body (casing) of the box is made of aluminum alloy. Inside the casing there is a primary (driving) and a secondary (driven) shaft. The shafts are combined with the differential and final drive. The five forward gears are equipped with synchromesh for improved shifting smoothness.

Gear ratios: 1st gear - 3.636, 2nd - 1.95, 3rd - 1.357, 4th - 0.941, 5th - 0.784. For reverse gear - 3.5. The gear ratio of the main gear is 3.7. The instruction manual says that you need to change the gear oil every 75 thousand km.

Mitigation of chassis impacts on the body, as well as ensuring stability and smoothness, is carried out by the forces of the front and rear suspension of the Lada 2110. An independent design is used on the front axle. Each wheel has an independent coil spring with a MacPherson strut inside. Each rack has its own hydraulic shock absorber. The lower arms are attached directly to the steering knuckles, and the anti-roll bar is attached to them. The levers help to reduce the roll of the wheel (turning it around the longitudinal axis). When the car makes a turn, the wheel turning "inside the body" may move away from the axis of rotation. The stabilizer prevents this from being done by twisting. Thus, the front suspension of the Lada 2110 allows you to maintain the stability of the car when cornering. Rear suspension is a rigid structure, the main element of which is a transverse beam. Since the rear wheels do not spin, maneuverability is not required and rear stability must be high. Therefore, such a design was applied. The beam consists of trailing arms attached to each wheel and a connector that holds the arms together by welding. The wheels on the rear axle are also equipped with hydraulic shock absorbers to absorb shocks. Radial tires 175/70 are installed on the Lada 2110. Ventilated disc brakes are used on the front wheels, and drum brakes on the rear wheels.

Increase engine power VAZ 2110. Consider the potential of a 2111 8V motor without replacing the cylinder head with a 16 valve one. The 103 16V engine and its modifications are mentioned in a separate article.

The easiest way to improve something is to replace the camshaft with OKB Dynamics 108 or Nuzhdin 10.93, install a split gear, adjust the phases. At the output, we get around 85 hp. at a minimum cost and a slightly more active motor. Let's let the engine breathe freely, put a receiver, a 54 mm throttle and a 4-2-1 spider exhaust, we get already under 90-95 hp and dynamics at the level of the Priors. To this we add the refinement of the cylinder head and intake manifold, light valves, cylinder head milling, the power will jump to 100 or more hp. For a further increase in power, it is recommended to increase the engine size 2111 to 1.6 liters by increasing the stroke to 74.8 mm. When using valves of increased diameter, lightweight valve plates, program settings, the car will show 110 or more hp, but in this configuration it is necessary to select evil shafts with a wide phase and a large lift. We will get an excellent sports engine for a VAZ 2110 with a power of 120-130 hp. and more.

Turbine for VAZ 2110

An alternative method of obtaining such power is to install a compressor with a pressure of 0.5 bar. With proper tuning and using a Nuzhdin 10.42 shaft or a wider Nuzhdin 10.63 (or other manufacturers with similar characteristics), the motor will produce about 120 hp +\-.

This free collection contains all the necessary documentation for the electrical equipment of the VAZ-2111 car - the circuit itself, the heating system, the headlight cleaner, the electronic engine control module and the fuse box. VAZ 2111 is the first station wagon in the line of front-wheel drive vehicles, which is a modernized concept of the rear-wheel drive VAZ 2104. In it, the wiring diagram for the injector and a number of other components have undergone changes as part of the concept change. The diagrams can be viewed here.

VAZ 2111 is the first station wagon in the line of front-wheel drive vehicles of the Volga Automobile Plant. It is a modernized station wagon concept, which for many years was implemented by the rear-wheel drive VAZ 2104. Accordingly, the wiring diagram of the VAZ 2111 to the injector and a number of other components have changed as part of the concept change.

Power units

First of all, significant changes have taken place in the engine compartment, since the VAZ 2111 car is equipped with 6 different engines:

model LADA-21110 is equipped with an 8-valve 1.5 l power unit with nozzles in the fuel supply system;
LADA-21111 is equipped with a 1.5 liter carburetor engine;
LADA-21112 has an 8-valve injection engine increased to 1.6 liters;
LADA-21113 is equipped with a 1.5-liter 16-capacity engine with an electronic ignition system;
LADA-21114 is equipped with a 1.6-liter 16-capacity engine with nozzles in the fuel supply system;
LADA-21116 demonstrates a 2.0-liter Opel engine. It is installed on the all-wheel drive model VAZ 2111, which has the name "Tarzan" - a video about its capabilities can be viewed on the automaker's website.

The photo above shows the control circuit of the power unit. It is labeled:

Starter unit (ignition relay - 1, battery - 2 and ignition switch - 3);
Emission control unit(pipe - 4 and oxygen sensor - 5);
Fuel block (high pressure nozzle - 6, fuel rail - 7, pressure regulators - 8 and idling - 9);
Air filter housing (10);
Diagnostic connector (11).

For reference: the "brains" of the injection system and non-contact ignition are the controller and the ECM, which work together with the standard anti-theft system. Its role is played by the immobilizer (in the diagram under No. 17).

electrical equipment

Depending on the installed power unit, the wiring of the VAZ 2111 also changes.

This is due to the fact that the car uses:

fuel injection systems;
Contactless ignition;
The transverse arrangement of the power unit in the engine compartment also affects the wiring.

After all, only the changed location of the motor forced the designers to develop:

Another layout of the wiring attachment points in the engine compartment;
To form wiring harnesses for close groups of devices and sensors in a different way.

Applicable controllers

The engine is controlled by an electronic controller. And for each modification, the manufacturer installed a specific model, which may not coincide with the factory documentation.

The automaker installed the following controllers on all cars:

GM model (2111-1411020-20);
January 4.1 model (2111-1411020-22);
model M 1.5.4 (111-1411020-00);
January 5.1 model (2111-1411020-61);
January 5.1.1 model (2111-1411020-71);
MP 7.0 model (2111-1411020-40).

Being shortened to 4170 mm bodies in comparison with the VAZ 2110, the new model has retained all the qualities of a hatchback. Reducing the base had a positive effect on the handling of the car, which made it a favorite among motorists of the domestic auto industry.

Historical reference

A fuel injection distribution system was installed on the car that meets the requirements of exhaust gas toxicity standards:

16 valve power unit equipped with an electronic system based on the M7.9.7 controller and complied with EURO 3;
8-valve power unit complies with EURO 2 standards.

For reference: the engine management system with distributed fuel injection for brevity is referred to in the schemes as an abbreviation - SUD. For the EURO 3 engine, it is equipped with an adsorber purge solenoid valve - in the diagram under No. 13.

EURO 3 - 16 valve version

The presented diagram shows the main components and sensors, thanks to which the CUD organized the supply of the air-fuel mixture to the cylinders:

The main components are the ignition coil, fuel injectors, controller and main relay (indicated in the diagram under numbers 1,2,3 and 4);
A larger group of sensors includes several systems at once: power supply, cooling, air supply, engine operation, etc.

The control systems for the operation of the power unit include:

throttle position sensor (No. 12);
knock sensor (No. 18);
diagnostic oxygen sensor (No. 16);
crankshaft position sensor (No. 19);
coolant temperature sensor (No. 13);
immobilizer control unit (No. 20);

In addition, the VAZ 21124 wiring diagram also contains built-in protection elements:

Main relay fuse (#5);
Relay and fuse for the electric cooling fan (No. 6 and 7);
Fuel pump relay and fuse (No. 8 and 9);

For reference: G1, G2 indicated in the diagram are ground points, A is the ABS system block, B is the diagnostic connector.

EURO 2 compliant power unit

The electronic filling of the car is similar to the 16-valve version:

single controller for power units M7.9.7
general factory instructions for cars with different power units.

In addition to the different markings of the sensors, the car circuits are identical, with the exception of the canister purge solenoid valve, which is equipped with EURO 3 engines.

Self service

Traditionally, owners prefer to service domestically produced cars with their own hands. And there is a certain reason for this, because:

Own car is given maximum attention;
Thanks to maintenance, the owner gains experience in repair work;
Maintenance costs are minimal.

For reference: a number of components and parts of the car have a different resource, during the development of which the part is subject to mandatory replacement. The wiring on the VAZ 21124, although not one of them, fails due to harsh operating conditions. Therefore, it also needs to be replaced.

On the attached photo scheme are presented by groups:

electric fan (No. 3);
relay for turning on the electric fan (No. 22);
coolant temperature sensor (No. 7);
electric fuel pump with fuel level sensor (No. 30);

Conclusions: we hope that the proposed video and decoding schemes will help you maintain the VAZ 21124 car. And thanks to your care and attention, it will last for many years, delighting you with reliability and trouble-free operation.

An electrical circuit is used to combine all electrical appliances and equipment in a vehicle. If any of its elements fails, this may affect the functioning of the car as a whole. You can learn more about what the VAZ 2111 wiring diagram is an 8-valve injector and what malfunctions are typical for it from this material.

What is included in the electrical circuit?

First, we propose to understand what systems and nodes are used in the wiring diagram.

Its main elements:

Battery. This device is designed to ensure the normal start of the engine, as well as powering electrical appliances and equipment at a time when the engine is not running. If the battery is discharged, it will not be possible to start the engine with the key, you will either have to try to start it from the “pusher” or “light it up”.
Starter. The purpose of this unit is to provide the ignition system with a high-voltage pulse necessary to ignite the combustible mixture in the ICE cylinders.
The generator is one of the main components of any electrical system. This node is necessary to power the electrical devices and appliances of the vehicle during its movement. In addition, the generator allows you to charge the battery, replenishing its charge, which went to start the engine.
Ignition switch.
Mounting block with fuses. The purpose of the fuses cannot be underestimated - these devices are used to protect the electrical circuits of a car. If power surges occur in the electrical system of the engine injector 16 valves, then it is the fuse that will fail first, thus protecting the equipment from damage (the author of the video is the Auto Electrician VCh channel).

But these are only the main components of the system, as for the complete electrical circuit, it includes various nodes and systems:

connection of the starter node;
non-contact ignition system;
ignition switch connection diagram;
a lighting system that includes optics for low and high beams, brake lights, position lights, fog lights, turn signals, as well as lighting in the car interior;
system for activating wipers, as well as a windshield and rear window washer;
sound signal activation circuit;
system of inclusion of electric windows;
activation of the ventilating device of the cooling system;
luggage compartment lock;
node;
instrument panel, which displays all the main instruments of the car, the status of sensors, speedometer, tachometer;
oven automatic control system;
generator unit connections;
power unit control.

Common faults

As you can see, in general, a 16-valve engine is a rather complicated system. Accordingly, there are also enough breakdowns in her work, all of them can be conditionally divided into several groups. For example, if you have suspicions about the functionality of the spark plugs, and they turned out to be working, then you need to check the operation of the ignition coil and high-voltage cables. As practice shows, breakdowns in the wires can also lead to incorrect operation of the ignition system. The failure of one or another element of the electrical network can be the result of both a breakdown of the device itself, and the failure of a generator unit or battery.

Most often, car owners are faced with the problem of battery failure, so consider the main malfunctions that are typical for this device:

a short circuit has occurred between the electrodes of the device;
damage to the plates located inside;
the appearance of cracks and other mechanical damage on the battery case, as well as sprinkling of plates, which can lead to leakage of electrolyte;
oxidation of the battery terminals, this problem can be solved by stripping.

All these malfunctions eventually lead to battery discharge. If we talk about the reasons that caused these problems, then most likely they all lie in improper operation, of course, if the battery life is high and has not yet ended. Much less often, the malfunction lies in a factory marriage, but this happens infrequently.

In order to prevent malfunctions in the operation of the battery, the following rules should be taken into account during operation:

First, the device must be securely fixed at the landing site. If the battery is not fixed securely, this can lead to constant vibrations, which can subsequently cause cracks in the case.
The operation of the car and, accordingly, the use of the electrical network is allowed only when using a workable generator. If the alternator fails or its belt is loose, it will eventually drain the battery.
In the event that the contact at the terminal of the device is poor, this can lead to its oxidation and destruction.
Discharging the battery is also facilitated by prolonged scrolling of the starter when trying to start the engine. Especially often this problem manifests itself in cold weather, when the battery electrolytes are less mobile, and the driver has to turn the starter longer to start it (the author of the video is Vyacheslav Kravchenko).

Depending on the type and manufacturer, the battery life can be between three and five years. However, the service life may be reduced if the battery is used in intensive and harsh conditions. One way or another, the consequence of a battery discharge is always the same - the device will not be able to crank the starter to start the engine, as well as power the devices and equipment of the car as a whole. In the event that the diagnostics showed that the battery is working normally, it is possible that the cause of the malfunction lies in the performance of the generator.

Its design as a whole is more complex, respectively, this node has enough malfunctions:

erasing brushes, due to their wear;
failure of the voltage regulator relay;
failure of the diode bridge;
bearing wear, which is accompanied by a hum during the operation of the generator;
wear of slip rings;
damage or wear of the pulley teeth;
short circuit in the stator winding;
damage to the wiring of the charging circuit;
broken or worn alternator belt.

Malfunctions in the operation of the node can be determined by diagnostics using a multimeter. As for the repair, it can be done by hand. We have already described the procedure for repairing a generator using the example of the VAZ 2114 model in this one, in the case of the VAZ 2111 it looks similar.

As for the remaining malfunctions in the operation of the electrical circuit, there may be several reasons:

failure of the device itself;
blown fuse caused by a short circuit (before replacing the fuse, it is necessary to determine the cause of the short circuit);
open circuit, the problem is solved by replacing the wire;
oxidation of contacts on the terminals of devices (the author of the video is the Ramanych channel).

Prevention measures

In order to prevent problems in the operation of electrical equipment, it is necessary to observe certain, in particular:

Charge the battery at least once a year with a charger. This is especially true before winter, as well as in cases where you plan to leave the car in the garage or in the parking lot for a long time. If the car will stand, then it is better to remove the battery altogether and charge it before installation. Also, the battery must be serviced, at least twice a year, check the presence of electrolyte in the system and the charge of the device with the engine running and turned off.
Never use low quality fuses. The same applies to the use of homemade fuses in the form of a wire or a coin. Drivers usually install home-made devices if a certain fuse is out of order, and there is nothing to replace it with. If you are faced with the need to replace, then of course, a home-made version can also be used, but only in order to get to the nearest store and replace it with a normal fuse. The use of "homemade" can lead to a short circuit and even fire.
Always install only high-quality appliances and equipment on your car - from the generator unit to the light bulbs in the dashboard. If the equipment is of poor quality, its service life will not be as long, especially since its use over time can cause inconvenience to the driver.
If there are problems with the operation of the equipment, they must be addressed immediately. For example, you saw that the Check Engine indicator appeared on the control panel - we recommend that you check the engine as soon as possible. For more accurate results, use computer diagnostics - it will help determine which of the nodes you need to pay attention to first. It should be noted that the appearance of this bulb is quite often due to problems in the operation of certain sensors. And their performance, in turn, may be impaired as a result of a broken wiring or oxidation of the contacts on the connectors. In this case, it is not necessary to immediately change the sensor - you need to change the wire and clean the contact - it is quite possible that this will solve the problem.
If there are short circuits in the operation of the electrical circuit, then they must be eliminated, since they can lead to damage to the electrical equipment as a whole.
Never forget that all network elements must be securely sealed, especially keep this in mind when installing equipment and wiring yourself. Car electrical appliances and their circuits should not be affected by moisture and other factors.

The VAZ-2111 engine uses a distributed fuel injection system (each cylinder has a separate nozzle). The nozzles are switched on in pairs (for 1-4 and 2-3 cylinders) when the pistons approach the top dead center (TDC).

Some engines are equipped with a feedback injection system (oxygen sensor) and a converter in the exhaust system. This system does not require adjustment and maintenance (if the exhaust gas toxicity standards are exceeded, the failed components are replaced).

On the other part of the engines, an oxygen sensor and a converter are not installed. In this case, the toxicity of the exhaust gases is regulated by a CO potentiometer using a gas analyzer.
