近年来,中速柴油机的排气污染问题越来越显得重要。已执行一项计划来制定当前固定式和机车柴油机的污染基准值。此中对氮的氧化物、碳氢化合物、氧化碳、烟度和微粒量进行了测量。本文提出了关于污染基准值的初期研究结果,讨论了燃烧重油、喷油延迟、燃烧室型式、渗水乳化油和降低气缸进气温度对污染的影响。
In recent years, the medium-speed diesel exhaust pollution problem is more and more important. A plan has been implemented to establish the current pollution baseline values for stationary and locomotive diesel engines. The amount of nitrogen oxides, hydrocarbons, carbon oxides, smoke and particulates was measured. This paper presents preliminary findings on baseline pollution values and discusses the effects of burning heavy oil, fuel injection delays, combustion chamber patterns, seepage emulsified oil, and reducing cylinder inlet air temperature on pollution.
