摘要：

The influence of EGR cooling temperature on NOx emission was studied under different operation conditions in CA498 diesel engine, and the optimum EGR cooling temperature was obtained under different operation conditions. An EGR cooling temperature control device is designed and the temperature is controlled by regulating the rotating speed of the accessional electric servo pump and ensures the optimum EGR cooling temperature. The flux of cooling water is controlled by the water pump. Testing result showed that the control system could effectively reduce the NOx, smoke and oil consumption while slightly increasing CO and HC emissions.
