The role of the injector

The fuel injector is one of the important parts of the car, and it is a relatively high precision device. Its main function is to atomize gasoline, and it can also control the range and the cone angle of diffusion. But the fuel injector is also divided into different types, and the 4 types of fuel injectors are more commonly used in daily life.

The first type is the pintle type electromagnetic fuel injector. When this type of fuel injector is used, the armature drives the needle valve, so that the fuel is sprayed out from the gap of the precision device. Moreover, in order to fully atomize the injected fuel, a section of the needle of the injector will be ground at the front end of the needle valve.

The second type is the ball valve type electromagnetic injector. As the name suggests, this type of injector is composed of a ball valve needle, and the quality of the ball valve needle is relatively light, and the preload of the spring is also very large and sensitive. Time to get a better dynamic flow range. Moreover, the sealing performance of the ball valve electromagnetic injector is very good, mainly because the ball valve has an automatic centering function.

The third type is the electromagnetic injector of plate valve type. This type of injector is often composed of a light valve plate and a hole valve seat. The dynamic flow range of this type of injector is relatively large. And the anti-blocking ability is better, that is to say, it will not easily block.

The fourth category is the lower fuel injector. This kind of fuel injector is also relatively common. It mainly uses the bottom oil supply method, and the cooling effect of the fuel injector is very obvious, so it can effectively prevent Air resistance is generated, which can improve the hot start force of the car.
