분사조건에 따른 디젤기관의 수트 및 질소 산화물 생성에 관한 연구

The effects of fuel injection conditions such as the start of injection, duration of injection, split injection in a diesel engine on the soot and NOx emissions are studied by using the KIVA-3V code. The results show the general trends of soot and NOx emissions. When the start of single injection is advanced or split injection is applied, the combustion chamber temperature is increased due to the prolongation of combustion process, consequently the soot concentration is decreased. In the other hand this phenomena caused the increasing of NOx emissions.
