[Overview of Fuel Injection System]
• The Transfer pump suction fuel from the tank and supplies it to the Fuel Pump.
• The fuel is pressurized by the fuel pump to a high pressure and then supplied to the common rail.
• The common rail accumulates fuel and acts as a fuel manifold to supply fuel to the fuel supply pipes of each injector.
• The high-pressure fuel supplied to the injector is injected into the combustion chamber at the optimum timing through the electronically controlled nozzle in the injector.
The common rail distributes the high pressure pump to generate high pressure fuel and sends it to the injectors of each cylinder. Shared oil tank
equipped with a fuel pressure sensor, and a pressure limiter.
The fuel pressure sensor test the fuel pressure in the common rail and the engine controller uses fuel pressure regulation
Fuel pump output.
If the common rail pressure exceeds the threshold setting, the pressure limiter is a relief valve that relieves pressure. From the pressure limiter
The released fuel flows from the common rail to the fuel tank through the return line.
