摘要：
This paper designs an electronic control EGR system used in diesel engine and researches the influence of different EGR rate on engine economy and the emission characteristics of the 13- modes cycle. The results show that the specific fuel consumption of the test engine rises at different degrees after using electronically controlled EGR technology, especially in high load areas; NOx emissions have a more significant decline and particles increase to a certain extent; Overall, however, emissions of HC do not nearly change; CO emissions are closely related to EGR rate.
