커먼레일엔진 EGR RATE에 따른 배기가스 변화에 대한 실험적 연구

An experimental study on exhaust gas variation depending on EGR rate of common rail engine

Current common rail engines are equipped with cooled EGR systems by using an engine cooling water system. In this study, investigations of exhaust gas reduction characteristics have been carried out in the common rail engine system depending on the EGR rate variation. The experimental results shows that NOx reduces and smoke increases as the EGR rate increases.
