摘　　要：为满足某款在开发满足国4排放法规要求的乘用车柴油机,在试验台架试验研究了一种新型的旁通式EGR冷却器,其可根据发动机实际运行工况,实现废气温度的一定范围可控。研究表明,在发动机部分运行工况下,通过旁通废气的方式,将废气温度控制在适宜温度范围,可有效降低尾气排放中的HC、CO排放量。In order to meet the needs of a developing country passenger car diesel engine to meet the requirements of 4 emissions regulations,in test bench test of a bypass EGR cooler model,according to the actual condition of the engine,to realize the controllable range of exhaust temperature.Research shows that,in the part of engine operating conditions,through the bypass exhaust,the exhaust gas temperature control in the appropriate temperature range can effectively reduce the HC,CO emissions in exhaust fumes.
