[디젤엔진] 디젤엔진의 Cavity Shape에 따른 KL치의 변화에 관한 연구 = A Study on the KL Value with Cavity Shapes in a Diesel Engine

다국어 초록 (Multilingual Abstract)

The present study deals with the effect of combusion chamber shape on in-cylinder soot oxidation characteristics of direct injection diesel engine. The anaylsed combustion chambers were a toroidal and a reentrant a reentrant with a projection(Complex). The two-color method was used to measure in-cylinder flame temperature and KL valve which is approximately proportional to the soot amount along the optical path. In addition, heat release rate was calculated from the in-cylinder pressure data. From this study, the soot oxidation of the reentrant and the complex which were strengthen squish flows went worse in late combustion period under heavy-load operation compared to that of the toroidal at retared fuel injection timing. It might be cause of the flame holding that squish lip depress the outflow of flame from the bowl to the entire combustion space.
