직접분사식 디젤기관에서 EGR 적용시의 배기배출특성에 관한 연구
A Study on the Exhaust Emission Characteristics with EGR Application in a DI Diesel Engine
- 발행 : 2005.08.31
초록
The Effects of cooled and hot EGR(exhaust gas recirculation) on the characteristics of smoke and NOx emission have been investigated using a single cylinder, water-cooled, four cycle, DI diesel engine at several loads and speeds. In this study, a manually controlled EGR system was installed on a agricultural diesel engine which was operated at various operating system. And, the effects of hot EGR and cooled EGR on smoke and NOx emission were compared. The results showed that cooled EGR method was more effective than hot EGR method on smoke and NOx emission.
