The fuel injector is one of the key components of the engine, its main role is to inject the right amount of fuel into the cylinder and mix with air to form a combustible mixture to provide fuel for the engine. The operating performance of the injector directly affects the performance of the engine and fuel consumption.
An injector consists of an injector and a valve body. The fuel injector is the core component of the injector, which is composed of a needle valve, a needle valve body, an injector spring and an injector housing. The valve body is another important part of the injector, which is composed of the seat, the spool, the spring and the body.
The injector works by injecting the right amount of fuel from the injector into the cylinder when the engine is running, according to the instructions of the engine control unit (ECU). Specifically, when the injector's solenoid valve is energized, the spool is attracted and moved to the valve seat, and the fuel enters the cylinder through the nozzle hole of the injector. When the solenoid valve is de-energized, the spool returns to its original position and the nozzle of the injector is closed, stopping the injection of fuel into the cylinder.
The performance of an injector is affected by a variety of factors, such as fuel pressure, the bore size and shape of the injector, the response time of the solenoid valve, etc. In order to ensure the proper operation of the injector, the injector needs to be regularly inspected and maintained. If the injectors fail, such as clogging, leaking or wearing, it will affect the performance and fuel consumption of the engine.
In short, the fuel injector is one of the key components of the engine, and its working performance has an important impact on the performance and fuel consumption of the engine. Therefore, we should regularly check and maintain the injectors to ensure that they are working properly.
