柴油机燃用乳化柴油的非常规排放特性

Research on the Unconventional Emissions of the Diesel Engine Burning with the Emulsified Diesel Oil

本研究进行了车用柴油机燃用纯柴油和三种不同配比乳化柴油的台架试验。对柴油机在不同转速和不同负荷下的SO2、CO2、醛类三种非常规排放物进行了检测,并对其变化规律和原因进行了研究分析。试验结果表明,和燃用纯柴油相对比,柴油机在燃用三种不同配比的乳化柴油时,非常规排放气体中SO2、CO2含量均有不同程度下降,而其中醛类含量在不同负荷和转速下的变化较复杂,在高负荷低转速时有所下降。

This article is on the research of the diesel engine respectively burning with the pure diesel oil and three kinds of different allocated proportions emulsified diesel oil in the bench test. We examined the three kinds of unregulated emissions gases, the sulphur dioxide, carbon dioxide and the aldehydes, under different rotational speeds and different loads, and analysed their change rules and reasons. The test result indicated that compared to the pure diesel oil, when the diesel engine burns with the three kinds of different allocated proportion emulsified diesel oil, the contents of the sulphur dioxide and carbon dioxide in the non - conven- tional emissions gas both have a varying droping. But the change of aldehydes content is complex under differ- ent loads and rotational speeds; and the content drops with high loads and low rotational speeds
