The world is moving to the newer generation to improve their economic towards the production of cars. Diesel engines are mainly used in the cars.these are used in the various form of fuel injections. Two common type direct fuel injections are distributor power system and inline power system. in common rail system a high pressure pump stores as the reservoir of fuel at high pressure up to 2000 bars.
Since the fuel pressure energy is stored remotely and the injectors are electrically actuated the injection pressure at the start and end of injection is very near the pressure in the accumulator (rail), thus producing a square injection rate.If the accumulator, pump, and plumbing are sized properly, the injection pressure and rate will be the same for each of the multiple injection events.in these type of engines the fuel injector may varies. If the accumulator, pump and plumbing are sized properly the injection pressure and rate will be even for both types.
