When the ECU sends a signal to the fuel injector, the injector opens and allows fuel to flow into the engine's cylinder. The amount of fuel that is delivered is controlled by the injector's opening duration. The longer the injector is open, the more fuel is delivered.
The fuel injector is a very important part of the engine's fuel system, and it must be working properly in order for the engine to run correctly. If the fuel injector is not working properly, it can cause the engine to run rich or lean, which can lead to several problems, including:
* A lack of power
* Engine hesitation
* Increased fuel consumption
* Emissions problems
If you are experiencing any of these problems, it is important to have your fuel injector checked by a qualified mechanic.
Here is a more detailed explanation of how a fuel injector works:
1. The fuel injector is supplied with fuel from the fuel pump.
2. When the ECU sends a signal to the fuel injector, the injector's solenoid valve opens.
3. The fuel pressure inside the injector causes the fuel to be sprayed into the engine's cylinder.
4. The injector's opening duration is controlled by the ECU.
5. The fuel injector closes when the ECU cuts off the signal.
Fuel injectors are usually very reliable, but they can sometimes become clogged or damaged. If a fuel injector is clogged, it will not be able to deliver enough fuel to the engine, which can cause the engine to run lean. If a fuel injector is damaged, it may leak fuel, which can cause the engine to run rich.
It is important to note that fuel injectors are very sensitive components, and they should only be handled by qualified mechanics.
