Design Of Common Rail

Posted on 12/30/2015 11:05:47 AM

The fuel is delivery to a high-pressure reservoir - fuel rail(2) by the primary pump (1).In order for subsequent injection of engine,the fuel is stored at the optimal pressure.

One injector(4)  with an integral solenoid valve is equipped in the each engine's cylinders.And the starting point and mass of the injection process is defined by the opens and closes of this solenoid valve. 

According to the parameters in the program map,the ECU (3) registers driver demand and current vehicle operating conditions in the basis for calculating the required fuel pressure, injection duration (= fuel mass) and injection timing.
