High injection pressures are a must in today's DI diesel engine fuel injection systems. The Common Rail injection system (CR), introduced in mass production about 2 1/2 years ago, will follow the trend valid for other fuel injection equipment (FIE), which calls for ever higher pressures.A CR injector design suitable for injection pressures of 2000 bar or more is presented in this paper. According to this design, injector prototypes suitable for passenger car and heavy duty truck applications have been realized.Important aspects for CR injectors operating at these high pressures are: These aspects are analyzed and the resulting injector performance measurements are presented here.
