摘要
本文介绍了对S195型单缸涡流室柴油机在各种负荷和转速下的废气排放(CO、HC、NO_x等)的测试结果。还进行了排气烟度的测量和排气中碳质微粒粒度和浓度的分析,并提供了部分结果。文中指出,为了减轻这种柴油机的排气对空气的污染,对柴油机的最大循环供油量进行适当限制是绝对必要的,也是极其迫切的。
Test results of an S195 diesel engine on exhaust emission (CO, HC, NOx) at various load and speed conditions with a horiba automotive emission analysis system, model MEXA-8220D, are reported. Exhaust smokemetry and paniculate size and concentration analyzing are also carried out and their results presented. It is indicated that in order to reduce the air pollution by the exhaust gas of this kind of engine, reasonable limitation of maximum diesel fuel delivery per stroke is absolutely necessry and extremely urgent.
