디젤엔진에서 커먼레일 시스템의 분사방법에 따른 기관성능 및 연소특성에 관한 실험적 연구

Common rail injection system is flexible in injection timing, injection duration and pressure in engine. Many research have reported the advantages in using common rail systems. In this study, the characteristics and performance for single cylinder diesel engine with common rail systems were investigated by changing the parameters such as injection timing, injection duration and common rail pressure. The injection timing and injection duration were controlled by electronic pulse generation, and common rail pressure were controlled by PCV driver. The 498cc single cylinder diesel engine was used in this experiment. All data in engine combustion pressure, injection timing and injection duration were recorded by Labview.
