[디젤엔진부문] 노즐 및 Cam 변화에 따른 전자제어식 유니트인젝터 시스템의 성능 고찰

The particulate meter.;(PM) can be reduced by improvements to the fuel injection equipment(FIE). The main requirement from the FIE is to provide high fuel injection pressures and an optimal nozzle design. This paper presents the electronic unit injector(EUI) system which has been designed to give high fuel injection pressure and electronically controlled injection timing and fuel quantity. An experimental study has been carried out on the Doowon EUI prototype with nozzle and cam profile variations.
