고압 LPG/디젤연료의 분무특성 비교
Comparison of LPG/Diesel Sprays in high Pressure Injection System
초록
LPG gains many advantages of a high octane number low emissions and low cost over conventional fuel. The fuel has been naturally used in engines to save running cost but the first generation fuel feeding system was not satisfied with stringent requirement for exhaust emissions, A liquid direct injection system into a cylinder has been suggested as a next generation system to maximize a fuel economy as well as to reduce emissions. In this paper LPG sprays are compared with diesel sprays in a high pressured surrounding condition in order to understand the high pressure spray characteristics, The spray images show that LPG spray penetrates further soon after the injection then the sprays stays in a distant. it may explain the flashing effect of LPG.
