摘　　要：城市车辆的平均车速和负载相对较低,排气温度低,尿素SCR系统无法正常工作,尿素溶液SCR系统要使柴油车达到更高的排放标准具有一定的局限性。开展固体SCR系统在重型柴油机上的基础理论研究,使柴油车达到更高的排放标准。The average vehicle speed and load of the urban vehicle are relatively low, the exhaust gas temperature is low, the Urea SCR system cannot work normally, and the urea solution SCR system has to make the diesel vehicle reach a higher emission standard with certain limitations. The basic theoretical research on solid-state SCR systems in heavy-duty diesel engines was carried out to achieve higher emission standards for diesel vehicles.
