Fundamental requirement:-The line diagram of CRDI shows that the system is controlled by ECU. The sensors in the system are used to feed the input in the ECU.ECU will provide the signal to the injectors on the basis of engine factors like engine load, engine speed, temperature etc. The various components of engine will be controlled by sensors. The required quantity of fuel in required time will be calculated by it.

Major Components includes- fuel injector, common rail, High pressure fuel pump, ECM/ECU, Pressure sensor, Rail pressure limiter.
