摘　　要：为配合车用煤制柴油油品开发,在装备可满足国Ⅳ排放的DOC+POC后处理系统和SCR后处理系统的柴油发动机上,测试3种煤制调和柴油及国Ⅳ、国Ⅴ石化柴油在法规要求的ESC、ETC、ELR循环下的排放性能。结果表明,煤制柴油DY-1整体排放性能表现最好,相对于GBⅤ柴油在NO_x方面降低6.7%,在PM方面降低15.9%;同一油品在两类后处理发动机上的NO_x排放整体趋势大致相同,且硫含量对颗粒物的排放影响较大。To cooperate with the development of Coal-to-Liquid diesel for automobile, emission performance of CTL diesel, China IV diesel and China V diesel are tested on diesel engines equipped with DOC＋POC aftertreatment system and SCR aftertreatment system and comply with China IV emission standard under ESC cycle, ETC cycle and ELR cycle. The results show that CTL diesel DY-1 displays the optimal performance emission, which reduces NOx emission by 6.7%, and PM emission by 15.9% as compared with China V diesel; whereas this CTL fuel shows the generally identical trend of NOx emission for two engines with aftertreatment system, and sulfur content affects PM emission remarkably.
