CRDI Engines Seminar Abstract, Report

An Introduction to CRDI Engines (Common rail direct fuel injection)
Usually the diesel engines are available in two different variants. These two variants are commonly known as TDI and CRDI. TDI is an acronym for turbo diesel engine while CRDI is an acronym for common rail diesel engine. Earlier designed engines used the TDI diesel engine. The CRDI engine makes use of the solenoid or piezoelectric valves. These valves allow a fine electronic command over the fuel injection system of the vehicle. The system actually gets the complete control over the fuel injection quantity and also for the amount of time it is supposed to be injected. The CRDI engines also produce a lesser noise compared to the normal TDI engines.

The CRDI engines supply higher levels of fuel atomization. The engine reduces the noise by controlling the control unit of the pilot injection system. The control unit injects a small amount of diesel before the final pilot injection. This methodology ultimately reduces the vibration and explosiveness. The CRDI engines are specifically designed for correct injection timing and quantity of variations in the fuel. The modern CRDI engines utilize as most as five injections every stroke. The modern CRDI engines are less polluting too. The emissions are very less in CRDI engines compared to TDI engines.
