What is the relay of the petrol pump VAZ-2110. How to use it with alarms

From the article you will learn about what a VAZ-2110 petrol pump relay is. It should be noted immediately that the difference between the carburetor and the injection system is enormous. The first works due to the difference in pressure in the atmosphere and inside the engine, but the second one is due to a lot of electronic components. And for the engine is responsible for a considerable number of sensors and actuators. But about everything - more. First it is worth considering what a gasoline pump is in the top ten, and also what it is needed for.

Fuel Pump Design

In fact, it's an electric motor that operates on DC power. It has an excitation winding on the rotor and a stator winding. The rotor is supplied with special brushes made of graphite. But most importantly - this engine drives a special design pump, which pumps gasoline. Consequently, the whole system as a whole is capable of creating some pressure of fuel in the pipeline. To start the whole construction, there is a relay for turning on the petrol pump VAZ-2110. It is at the feet of the passenger, on a separate block. Here you can also find a fuse that protects the power circuit. In addition, the sensor of the level of gasoline in the tank is also constructive in a single unit with the pump. The most common float pressure sensors or ultrasonic sensors on cars, especially dozens, are not used.

Fuel system operation dozens

So, where do you start when you get into the car? Correctly, turn the key in the ignition and wait for a few seconds, until "something there from behind stops buzzing." Some do not even think about what is being released for sounds. And this works the pump motor. After all, when the ignition key is turned off, the VAZ-2110 petrol pump relay closes the circuit, and supplies power to the motor. Consequently, the pressure in the fuel system begins to be pumped. Without injection, the injection system can not work. When it reaches the operating value, the motor stops rotating. And when it falls below the minimum pressure value, the power is supplied to the motor and pressure is again injected. Consequently, the gasoline pump does not work constantly, but cyclically, it depends on the pressure in the fuel rail.

A few ideas that are used by motorists

And now you need to talk about the safety of the car. Of course, even if it's an old ten, it's a pity. And in the case of banal theft, the owner drops his hands. But it saves at times even the most simple alarm system, which blocks the vital electrical circuits of the car. In particular, by means of the power output of the car alarm it is possible to open the power circuit of the relay of the petrol pump VAZ-2110. Injector in this case simply will not work, as the pressure in the ramp does not increase. It is also possible to open the power circuit of the entire electronic control unit. In other words, when you turn on the ignition (provided that the car is not disarmed) you will not hear a characteristic "buzz" from the rear of the car.

Conclusion

In fact, the relay of the petrol pump VAZ-2110 is a simple electromechanical device. It serves to supply power to the main vital organ in the injector injection system - a pump pumping fuel into the ramp. It is not difficult to replace it, only it can not be repaired. Fortunately the price is quite acceptable - on average 80 rubles. But the most important of all the above is that the relay can be used a little "not for its intended purpose," namely, in order to protect against intruders. Even if you do not have an alarm, just install a secret button that will control the power supply to the electromagnetic relay. Of course, only you should know about its existence.
