초희박 직접분사식 가솔린엔진에서 분사 및 점화ㆍ전략에 따른 배기 특성

다국어 초록 (Multilingual Abstract)

Particulate matter are became a concern and will be limited by future emissions regulation in gasoline direct injection(GDI) engines. Such as the upcoming Euro 6 legislation BMW N53 3.0L In this research, GDI engine was used to universal ECU. Universal ECU was operated under a mototron program is based on MATLAB simulink program. The size distributions are measured using a scanning mobility particle sizer (SMPS). The size distributions are measured using a scanning mobility particle sizer. THC, NO<SUB>x</SUB> and emitted particle are reported for ignition timing injection timing and number of injection at 1500rpm BMEP 1.5bar condition. The result shows that increased THC and decreased particle size at advanced injection timing. However THC, NOx and particle size was measured to same value at advanced ignition timing.
