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。
Improving emissions is an important direction for the current development of small bore multi-cylinder diesel engines. Among the many influencing factors, the initial experimental study on the influence of four kinds of parameters on the gaseous emissions was carried out. The test results show that the injection advance angle, the total area of the nozzle holes, the inlet water temperature and the intake density have a significant effect on the emissions of CO, HC and NO x.
