Abstract
We design an electronic control EGR system using in diesel engine,and influence of different EGR rate on engine economy and emission is done.The results shows:using electronically controlled EGR technology,for the test engine,the fuel consumption rises at different degrees,especially in high load areas;NOx emissions have a more significant decline;particles increase to a certain extent;HC emissions have little change.
