What is an injector?

Almost all new machines now have an injector in them. Thanks to him, the car is not so "puffing", there are no dips in motion, less fuel consumption and the car is going very smoothly. That's all, probably, what inexperienced and unfamiliar people can say about the question: what is an injector?

Let's look first at the fact that we will give an answer to this question. And the answer is quite simple, because the injector is a special system of electronic fuel injection in a car, which is a jet pump( in the form of an injector).And this injector mixes, squeezes and pumps the mixture from air and fuel. Proceeding from the fact that the injector is intended for, we will single out its main structural parts, these are:

  • The working nozzle, from which the enriched mixture is already emitted.
  • Receiving chamber.
  • Mixing chamber.
  • Diffuser.

Having dealt with the main design parts of the injector, proceed to the next question, what does the injector do, how does it work?

Principle of operation of the

car injector. As an injector, this is an electronic system, that means, apart from the actuator itself( the injector), the car will be stuffed with special sensors to bring everything into one tuned fuel delivery mechanism to the engine.

And the working cycle of the injector is:

  • Petrol from the tank of the car through special channels, under pressure, about 4 - 5 atmospheres, is fed to the engine with a special electric pump.
  • Next, the fuel is suitable for the regulator, which is responsible for regulating, maintaining and maintaining the fuel pressure in the system.
  • Already after this regulator, the fuel passes to the injectors. The amount of fuel supplied is controlled by the time it takes to open the injector itself - everything is simple.

The process is quite simple, like carburetor fuel input to the engine, but to calculate the correct proportion, the amount of fuel in the injector system is a special processor that processes the signal from a large number of sensors, such as: air temperature sensor, engine speed, throttle sensorflaps, the air content sensor in the mixture. After that, the processor emits a pulse, thanks to which the necessary portion of fuel is given out, it is injected into the combustion chamber where it mixes with air and ignites.

Now you know what an injector is for and how it works. Good luck in choosing a car!
