직접분사식 가솔린 엔진에서 에탄올 혼합연료의 분무 및 연소특성

다국어 초록 (Multilingual Abstract)

An experimental study was carried out to investigate the effect of ethanol concentration in ethanol blended gasolone on spray characteristics, engine performance and emissions in a single cylinder spray guided direct injection spark ignition engine. The planar laser induced fluorescence and planar Mie scattering macroscopic spray imaging were conducted using simulated fuel. Ethanol showed faster evaporation, enhanced local homogeneity and smaller liquid phase area near the spark plug. The For the engine experiment, it was shown that increased ethanol concentration in ethanol blened gasoline gives wider stratified combustion range in terms of injection timing due to faster evaporation, lower combustion instability and NOx emission due to enhanced local homogeneity and increased IMEP because additional retardation of injection is available.
