Common Rail System: Design
The primary pump (1) supplies fuel to a high-pressure reservoir, the fuel rail (2), where the fuel is stored at the optimal pressure for the engine's instantaneous operating conditions in preparation for subsequent injection.
Each of the engine's cylinders is equipped with an injector (4) featuring an integral solenoid valve. This solenoid valve opens and closes to define the starting point and mass of the injection process.
The driver's demand is defined by the accelerator pedal. The ECU (3) registers driver demand and current vehicle operating conditions as the basis for calculating the required fuel pressure, injection duration (= fuel mass) and injection timing according to the parameters defined in the program map.
