Fuel pump Bosch VAZ 2110 - price

The injector power supply system of domestic cars evokes sacred awe among the public, genetically already accustomed to carburetor power options. There is no need to be afraid of the injector. The whole system, taken together, is much simpler than any VAZ carburetor. The carburetor is a small engineering masterpiece, and the fuel injection system is just a bunch of parts. Simple items.

VAZ 2110 injector and power system components

The very first batches of a dozen came out with eight carburetor engines, now they were replaced by an injection engine. However, there were no particular differences in the design of the motor. There was only a difference in the power supply scheme and the devices serving it. Later, with the arrival of the 16-valve engine, the control of the power plant became somewhat more complicated, and this added several additional elements to the power system.

Ten injection consists of:

for supplying fuel to the ramp;
a fuel module that includes a pump;
ramps for power distribution to cylinders;
nozzles that inject and form the correct flame, do the dosage;
pressure sensors and other peripheral sensors;
coarse and fine cleaning;
pressure reducing valve.

There are enough elements, but each is a simple device, and together they provide an accurate and uninterrupted supply of fuel to the combustion chamber.

Design and principle of operation

When it comes to the fuel pump (pump) dozens, you need to understand that the fuel module and the pump are separate units. Therefore, replacing the entire module in case of failure of the pump or its electric motor is impractical. The module consists of a plastic case, which contains both the pump itself and the fuel level sensor in the tank.

It is made in the form of a glass, and access to the module opens from under the rear seat, if you remove the plastic casing. The module has terminal contacts through which 12 V power is supplied.

It is a submersible device with a simple design. It consists of an electric motor and a pump, the rotor of which is on the same shaft as the rotor of the electric motor. It can only work under conditions of constant immersion in gasoline. He has no other sources of lubrication, and when working in dry mode, it instantly breaks down. In addition to the function of lubrication, it also has a cooling effect, therefore, dry operation of the mechanism is strictly prohibited.

Reasons for failure

In principle, he does not have a definite resource, and the state is judged by the pressure that he creates. The main reason for the failure is poor quality gasoline, the main fuel at our filling stations. Mechanical impurities, which must be carefully filtered out during the production process, enter the tank, and from there, everything that is not left on the coarse filter screen goes straight into the precise pump mechanism, which causes its rapid breakdown. Therefore, it is worth replacing this very mesh from time to time, although this is not provided for by the service regulations.

Manufacturers and characteristics

There are at least two dozen device manufacturers on the market, but more often than not, the public tends to replace more well-known brands. Bosch for a dozen, the price of which, by the way, is not less than three and a half thousand, is not a panacea, since every decent manufacturer will be able to provide the necessary characteristics of the device, and there is no need to talk about reliability, since you need to take into account the quality of the fuel. There are a lot of manufacturers of catalog part 0 580 453 453 on the market: Saratov, Utes, GM, and Bosch himself. Prices differ almost by half, but you need to understand that Bosch is an international company, and products with their logo can be produced in Germany, China, Malaysia, India, Czech Republic, Poland. And in Saratov. Therefore, these inscriptions should not be taken to heart. The main thing is the characteristics:

If you come across a copy that exceeds the nominal value, you should not panic, because it is on the ramp, it sends the excess through the return channel to the gas tank, it does not go anywhere and the consumption does not increase.

Examination

If you have any doubts about the device's performance, you just need to check the pressure on the ramp. It must be at least 2.8 atmospheres. Only then can the power supply system ensure the correct supply of fuel to the combustion chamber. Correct means uniform, dosed and with optimal torch geometry. If it is less than 2.8 atmospheres, fuel consumption may increase. This is due to the fact that the nozzle is not able to form a torch, but simply pours liquid into the chamber. where it does not burn out. Hence the instability of work.
