What is a crdi engine?

Answer 1

Common Rail Direct Injection (CRDI)

Did you ever shy away from buying a Diesel car thinking that you would be buying a taxi? If yes then you can rethink your decision as CRDI engines are all set to revolutionize the way one looks at Diesel cars.

CRDI engine fitted cars offer 25% more power than the normal direct injection engine with a superior pickup and torque offering sometimes up to 70% more power than the conventional diesel engines.

They are smooth less noisy and immensely fuel efficient giving around 24 kilometers to a liter of Diesel. The fact that Diesel is cheaper than petrol in India further attributes greatness to the engine. In a CRDI engine, a tube or a common rail connects all the injectors and contains fuel at a constant high pressure.

This high pressure in the common rail ensures that when injected, the fuel breaks up into small particles and mixes evenly with the air, thereby leaving little un-burnt fuel thus reducing pollution. The common rail principle has been used to cut out the noise factor which used to be associated with Diesel engines; the technology has been pioneered by the Fiat group, only to be adopted by other automobile companies around the world.

Like all good things in life, these engines also come at a price; they are at least 25% more costly than the conventional engines. They also require a higher degree of maintenance and spares aren't cheap also.
