Engine volume vaz 21041 40. Features of the VAZ wiring and its replacement

In the early 80s, in order to replace the VAZ-2102 station wagon, which was already outdated by that time, the specialists of the Volzhsky car factory started designing new car. The designers were faced with the task of creating new station wagon at the lowest cost and maximum effect. The VAZ-2104 sedan was taken as the basis of the car, which had to be redone. As a result, in the second half of 1984, a new station wagon from the VAZ automobile plant was born with the factory index VAZ-2104, or simply “four”.

Station wagon VAZ-2104 was completed various engines, including diesel engine VAZ-341. Over time, after another upgrade, the car received a 5-speed gearbox.

Compared to the previous station wagon, the VAZ-2104 had a number of advantages and by 1985 it completely replaced the “two” from production, so for the next 15 years the car was the only station wagon of Togliatti production until the appearance of the VAZ-2111. In 2003, AvtoVAZ ceased production of the VAZ-2105 station wagon, but from that moment until 2012, Izhevsk Automobile Plant continued its production.

Design and construction

Compared to the VAZ-2105 sedan, on the basis of which the VAZ-2104 was created, the station wagon received less rigid body. After lengthening the roof, stampings appeared to increase rigidity, however, the resulting rigidity was not enough and in order not to flush the roof, it was not recommended to heavily load the trunk located on it. In the rear of the car, for access to the trunk, an upward opening door was placed, the glass of which, unlike the previous station wagon, received heating and a wiper.

The interior of the VAZ-2104 station wagon was exactly the same as that of the VAZ-2105 sedan, with the exception of rear seats, which, as it should be for station wagons, could be folded, thereby increasing the volume luggage compartment. Trunk volume was 375 liters by default, and when the seats are folded, increased to 1340 liters, thereby allowing you to carry oversized cargo weighing up to 455 kilograms. Among the shortcomings, it can be noted that it was much more difficult for a standard heater from a sedan to warm up a significantly enlarged interior in the cold season.

As power unit on the station wagon VAZ-2105 installed exactly the same engines with a volume of 1290 to 1689 cm3 and a power of 64 to 84 Horse power. But, despite the fact that the engines were the same, the speed of the station wagon was lower (137 km / h instead of 143) due to the less streamlined shape of the tail. Since 1999, a small-scale modification of the station wagon with the factory index VAZ-21045D was produced, which was equipped with a VAZ-341 diesel engine with a volume of 1.52 liters and a power of 50 horsepower. The diesel station wagon was much more expensive, but given that at the time diesel fuel cost much cheaper than gasoline, the operation of this modification was cheaper.

Modifications

VAZ-2104

Basic version wagon, with carbureted engine from VAZ-2105, with a volume of 1.3 liters and a capacity of 64 horsepower. Equipped with a 4-speed gearbox.

Salon, electrics and front seats as in the previous modification, also borrowed from

At one time, AvtoVAZ began production of the VAZ-2104 car, a model that replaced the already outdated VAZ-2102. This car became the second and last representative station wagons in the family classic models VAZ.

The speed of creating a model and launching it into production was ensured by the fact that another model, the VAZ-2105, was taken as the basis. In fact, the designers simply took the "Five" and made a station wagon out of it, which received the index 2104. Therefore, almost all constituent elements, as well as the wiring diagram of the VAZ-2104, were completely unified with 2105.

But unlike the Five, the station wagon was produced for quite a long time - until 2009, and this car was modernized several times. The latest modification has already been equipped injection system power supply, which entailed the processing of the electrical circuit.

Main building blocks

But everything is in order. Scheme of electrical equipment VAZ-2104 (carburetor)- single-wire, that is, all electrical devices connected to each other by only one wire - "positive". The role of the minus is performed by the car body and metal components (power plant, transmission).

All devices included in the electrical equipment can be divided into several components:

• Working equipment (with the help of which the start-up and operation of power plant);
• Light and sound alarm;
• Auxiliary equipment (facilitating the operation of the car);
• Devices to ensure comfort;

The working equipment includes a battery, a starter, a generator, elements of the ignition system, as well as devices that control these parts.

At the same time, the battery can be attributed to almost all components, since it provides power to all car devices until the engine is started.

But its main task is to provide power to the starter - a power electric motor, with which the engine is started, as well as the ignition system. After the engine is started, the battery functions are taken over by the generator, that is, it generates energy, which feeds all devices. Also, his task is to restore the charge expended by the battery for starting the engine. At the same time, in the event of a heavy load (many electrical appliances are turned on), when the generator can no longer fully power the equipment involved, the battery begins to feed the network so that excessive load does not disable the generator.

The ignition system provides the creation of a spark charge in the engine cylinders, resulting in air-fuel mixture ignites. It consists of an ignition coil, distributor (distributor), spark plugs, high voltage wires.

The main control element of the working equipment is the ignition switch, through which electricity is directed to the necessary working devices (ignition system, starter).

Light and sound signaling provides illumination of the roadway in dark time days (high and low beam headlights), informs other participants traffic about the maneuvers performed by the driver (turns, overtaking, braking, reversing), as well as information about the dimensions of the car ( marker lights). This also includes sound signal and interior lighting fixtures. Powering everyone lighting fixtures is carried out from the battery (until the engine is running) and the generator (when the engine is running).

To ensure safety and prevent burnout of electrical appliances, all wiring is insulated. Additionally, all equipment is powered via fuses, which are collected in one block. That is, for example, if the dimensions do not work, there is a high probability that a short circuit or electrical wiring has occurred, through which these lighting devices are powered. Wiring diagram of the fuse box VAZ-2104 printed on its cover, which allows you to quickly find which section of the circuit and equipment fuse has blown.

Note that this system of electrical equipment was initially equipped only with export models of the VAZ-2104. It became standard for the subsequent modification of the station wagon - 21043.

For comparison, below is a diagram of the electrical equipment of the VAZ-2105, which was standard for the first station wagon models:

The diagram shows that the first station wagons were not equipped with a rear window heating and cleaning system, headlight washers and cleaners, as well as their control mechanisms. Otherwise circuit diagram identical.

Scheme of electrical equipment VAZ-2104 injector differs in that this car already uses electrical equipment borrowed from injection model VAZ-2107. This modification of the station wagon received the designation VAZ-21047 and it was the last in the history of this car.

VAZ-21041 VF. Salon, electrics and front seats as in the previous modification, the radiator grille was also borrowed from the VAZ-2107. It was equipped with a 1.5 liter injection engine from the VAZ-2103 and a 5-speed manual gearbox.

This resonator is installed on VAZ 2104, 2106, 2107 Izhevsk assembly With injection motor and Euro-3 standards.

How to understand which resonator is installed on your car and distinguish one from the other?

As a rule, Euro-2 resonators were installed on cars manufactured before 2008. In 2008 and beyond, Euro-3 resonators began to be installed. But this information cannot be 100% trusted, so we will tell you how to visually distinguish Euro-2 resonators from Euro-3 on a VAZ 2104 assembly of IZH-auto.

If you put these 2 resonators side by side, you will see that Euro-3 is shorter than Euro-2 by several centimeters. But if your burned-out resonator is still on the car and there is nothing to compare it with, in order to understand which of the 2 you should choose, look at the catalyst, which is also a converter exhaust gases, to which the resonator is screwed (in the picture, the catalysts are replaced by inserts).


If you see a catalyst into which an oxygen sensor is screwed and on one of its sides there is a flange for 3 mounting bolts, then you need a Euro-3 resonator. If you see a catalyst that has a flange for 2 bolts on both sides and an oxygen sensor is not screwed into it, then you need a Euro-2 resonator.

The operation of any electrical equipment in a car is directly related to the performance of the wiring. If there are breaks in the circuit, this may affect the functionality of the equipment as a whole. From this article you can find out what a VAZ 21043 carburetor is with detailed description elements.

What is included in the electrical circuit?

The VAZ 2103 or 21041 scheme, regardless of the ignition system used, includes the following elements:

• battery, the negative output of which is connected to the body;
• starter;
• regulator relay;
• BP - a block with fuses designed to protect equipment from short circuits and high voltage;
• generator, which is one of the main components of the VAZ wiring;
• ignition switch.

On any VAZ car, negative outputs from energy consumers are output to the mass, namely, to the car body. The car body itself is an excellent conductor. But as for the wired connection, it should be borne in mind that it is provided only with positive wiring. Above is a VAZ 2104 and VAZ 2103 diagram with all electrical circuits and the designation of all elements, and below is a table that indicates the purpose of all relays.

Signs of inoperability of the electrical circuit

Wiring VAZ 2104 is weakness, constantly something does not work. Since the production of cars of this model was discontinued many years ago, often VAZ car owners with a carburetor or injector are faced with the problem of equipment inoperability. If the electrical equipment began to work incorrectly, the motorist needs to diagnose the circuit. Always remember that when carrying out electrical wiring repair work, the system must always be de-energized. Checking the performance of certain devices is carried out on the basis of studying the circuit.

If you notice that there are problems with the electrical circuit, the vehicle can operate in one of two states:

1. If the car cannot move and does not even start, then in general possible causes, according to which this happens, there are many. In such cases, first of all, the diagnostics of the operability of the distributor and starter are carried out, it is also necessary to check the charge of the battery. IN winter time years, owners of "fours" with old batteries often face a similar problem as a result of a complete discharge of the battery. As practice shows, a complete failure of the generator happens much less frequently, however, the performance of this device also needs to be checked.
2. The car can start and even drive, but there are malfunctions in the operation of the equipment. Problems can also be very diverse - and short circuits, and breaks, and failure of the fuse, and breakdown of the equipment itself. It would seem, why not at the same time, windshield wipers, rear view heating? At first glance, these elements are not connected in any way, but it is worth remembering that they all work when the ignition is turned on, and everything falls into place.

According to experts in the field of wiring repair, the first thing to do is to check the ignition switch device, as this component is designed to:

• control of all the functionality of the ignition system;
• alarm management vehicle(video by Edward Deviatkin).

Troubleshooting

So, if you want to check the performance of all elements of the wiring diagram, you must follow certain steps. If there are problems in the operation of the equipment, then first of all it is necessary to check whether the fuses installed in the unit are working. If everything is in order with the fuses, but, for example, the optics do not work, then you will need to check the lamps. If everything is normal with them, then the wiring is dialed using a tester.

In the event that the car does not start at all, you will need to perform the following steps:

1. First, check the battery, as mentioned above, a full discharge may make it impossible to start the engine.
2. If the battery is charged, you need to ring the section of the circuit from the ignition coil to the generator. It often happens that breaks are to blame. If breaks are detected in the wiring diagram, it is necessary to replace the wires. If you notice that there are oxidations on the contact contacts, then they must be eliminated. To do this, the contacts are either changed or cleaned.
3. If the coil does not spark, the engine will not start. To check if there is a spark, pull high voltage wire and bring it to the mass, that is, to the iron (body, for example). Your assistant at this moment must turn the starter to start the internal combustion engine. At the time of the start attempt, a spark should flash between the wire and the ground.
4. Troubling the engine and the inability to start it is often associated with the operation of bad spark plugs. hinder normal operation the power unit can deposit and plaque that appears on the electrodes. Accordingly, with too much plaque, the appearance of a spark will be impossible. To solve the problem, it is necessary to clean the candles, detailed instructions You .
