| 摘 要： | 以某一四缸、增压直喷柴油机为样机,利用专业试验台架,首先对样机的喷油提前角和EGR率进行了不同工况下的标定,从而使柴油机排放物中NOx的排放量达到了欧Ⅳ排放标准；随后联合利用柴油氧化催化器(DOC)及微粒氧化催化转化器(POC)技术对柴油机尾气排放进行了试验研究,从而使柴油机废气排放物指标完全达到了欧Ⅳ排放标准.通过本试验研究,总结出了实现柴油机欧Ⅳ排放标准一种方法,并总结了此种方法的特点及规律. |

| Abstract: | This paper calibrates the advanced injector angle and EGR of a four-in-line pressure engine on the specialized test stand, which makes the NOx achieved the standard of Euro IV. Then an experiment study of the diesel oxidation catalyst (DOC) and the particulate oxidation catalyst (POC) are made. Both make the diesel engine emission achieving the Standard of Euro IV. This experiment study shows a kind of method that realizing diesel engine emission standard of Euro IV, and concludes the character and law of the method. |
| Keywords: | diesel engine emission advanced injector angle EGR diesel oxidation catalyst (DOC) particulate oxidation catalyst (POC) Standard of Euro IV |
