The Common Rail injection system main parts: A Transfer Pump A High Pressure Pump A Low Pressure Actuator IMV (Inlet Metering Valve) A Rail Injectors DCU (Diesel Control Unit) that controls injection (flow, timing, multiple injection) and rail pressure as a function of engine operating conditions. A High Pressure Actuator also known as the HPV (High Pressure Valve). A Force-feeding pump Sensors: - A rail pressure sensor. - A inlet air pressure sensor. - A fuel temperature sensor. - A pedal sensor. - A inlet air temperature sensor. - A phase position sensor either on camshaft - A accelerometer sensor. - A engine flywheel angular position sensor.

IMV Diesel temperature sensor High Pressure Pump Rail pressure sensor Injector Venturi HPV Rail Diesel filter.

The DCU can have several descriptions, as follows: ECU as in Electronic Control Unit, Diesel Control Unit (DCU) DCM as in Diesel Control Module. This unit is the heart of the injection control system. The DCU manages the following: Connection with sensors and actuators Connection with actuators Control of actuators Processing of sensor and actuator signals Strategy control. Communication with other ECUs.
