WebMay 27, 2024 · The common rail direct injection system is a modular design that has a common rail, electronic fuel pump, fuel tank, fuel filter, ECU, injectors and sensors. The fuel from the. fuel tank is fed into the filter and then to the fuel pump. A high-pressure pump pressurises the fuel. A pressure regulating valve is attached to the high-pressure pump ... WebDiesel is sent with very high pressure to the rail where each injector is fueled. In this type of injection, the injectors work more or less like “taps” that simply allow a certain amount of diesel to pass at a certain time. The injectors are electrically controlled, which is why problems can occur over time.

Solenoid or piezoelectric valves make possible fine electronic control over the fuel-injection time and quantity, and the higher pressure that the common rail technology makes available provides better fuel atomisation. To lower engine noise, the engine's electronic control unit can inject a small amount of diesel just before the main injection event ("pilot" injection), thus reducing its explosiv… WebElectromagnetic – or solenoid – injectors have a traditional coil, like you would see for a gas injector. The voltage that’s applied to the coil pulls the solenoid valve up. As it does, it allows the check ball to move up with it. Below the check ball is the inlet in the side of the injector for the high pressure fuel.
