摘要
在发动机试验台架上,利用快速型微粒光谱仪(DMS500)测试了缸内直喷汽油机燃用甲基环戊二烯三羟基锰(MMT)汽油后颗粒物的排放,分析了MMT对颗粒物排放的影响规律,试验用油为一种不含MMT的基础油和3种调和油(MMT+基础油),试验工况为不同的转速和负荷.研究发现:在全负荷下,同种燃料排放数量浓度有随着转速增加而增加的趋势;在转速不变时,同种燃料在小负荷时排放略高于中等负荷,中等负荷微粒排放最低,在大负荷时急剧增加;随着汽油中锰的浓度增加,车辆尾气排放中PM2.5数量排放有增加趋势.
The effects of methyl cyclopentadienyl manganese tricarbonyl(MMT) on emissions for the gasoline engine were studied using the DMS500 instrument on a chassis dynamometer.The fuels used in this study were one base gasoline and three types of blend oil(base gasoline with MMT).Different revolutions per minute and load were tested.Results showed that:under the full load,the same fuel emissions number concentration increases with the increasing trend with the revolutions per minute;the number concentration of emissions used same fuel reached the minimum in medium load,when revolution is constant,which will increased dramatically in heavy load;with increasing concentration of manganese in gasoline,the number of PM2.5 in vehicle exhaust emission was increased.
