What is CRDi technology in Cars

Common Rail Direct Injection -- makes the diesel engine run like a gasoline-powered one.

CRDi is an acronym used by some major automobile manufacturers for the revolutionary Diesel fuel delivery system called Common Rail Direct Injection. This is in stark contrast to the mundane low pressure diesel pumps of yesterday. Pressure up to 1700 bars in maintained in the common fuel rail which has Piezo injectors which allow diesel to be directly injected into the combustion chamber at this high pressure. Instant atomisation takes place & this spray is very fine & evenly distributed aiding efficiency & power delivery. Also the injectors can inject upto 5 times per combustion cycle which gives a more uniform & controlled combustion & helps extract maximum energy from the combustion cycle. Very sophisticated & brainchild of a Mr. Hiber of Switzerland. It was introduced commercially by Denso Corporation of Japan & in the 90 is all major european passenger vehicle manufacturers used this technology to get more refined, powerful & fuel efficient Diesel engines into the demanding market.

Many variations exist of the above said model but this is like the latest l guess!
