【摘要】 改善排放是小缸径多缸柴油机当前发展的重要方向。在诸多影响因素中,取4种参数对气态排放量的影响进行了初步的试验研究。试验结果表明,喷油提前角、喷孔总面积、进水温度及进气密度对CO,HC,NO_x的排放量有明显的影响。更多还原

【Abstract】 Improving exhaust performance is an important aspect in developing the small size multi-cylinder diesel.In this paper,tests about four parameters which mainly affect the gas exhaust have been done.The results show that injection timing,total nozzle hole area,inlet water temperature and inlet air temperature have obvious effect on exhaust value of CO,HC and NOx.更多还原
