CRDI (Common Rail Direct Injection):-
Whereas ordinary diesel direct fuel-injection systems have to build up pressure new for each and every injection cycle, the new common rail (line) engines maintain constant pressure regardless of the injection sequence.Same pressure of fuel is injected in each cylinder.
Advantages & Disadvantages :
Advantages:-
CRDi engines are advantageous in many ways. Cars fitted with this new engine technology are believed to deliver 25% more power and torque than the normal direct injection engine. It also offers superior pick up, lower levels of noise and vibration, higher mileage, lower emissions, lower fuel consumption, and improved performance.
In India, diesel is cheaper than petrol and this fact adds to the credibility of the common rail direct injection system.
Disadvantages:-
Like all good things have a negative side, this engine also have few disadvantages. The key disadvantage of the CRDi engine is that it is costly than the conventional engine. The list also includes high degree of engine maintenance and costly spare parts. Also this technology can’t be employed to ordinary engines.
