直接噴射式 디젤機關의 메탄올 混入량 變化에 따른 機關特性에 관한 硏究 = A Study on Engine Characteristic at the variation of Methanol Fumigation Volume in DI Diesel Engine

다국어 초록 (Multilingual Abstract)

The effects of methanol fumigation on engine performance and emissions characteristics, instantaneous temperature and heat flux in combustion chamber wall of direct injection diesel engine have been investigated. As the amount of methanol fumigation increasing, the engine output decreases, and the emissions concentration of smoke and NO_(x) decreases remarkably, and the instantaneous surface temperature and heat flux of combustion chamber wall are decreased. Maximum heat flux at methanol volume ratio 30% decrease 2.3MW/㎡ and maximum heat flux reduction rate decrease 39% than that of diesel engine.
