With the increasingly stringent fuel consumption regulations and emission standards,many new technolo-gies have been applied to the engine,and the application of exhaust gas recirculation(EGR)technology in the engine has become one of the main technical routes.On the basis of EGR system,firstly,the working principle of EGR system and pulse converter is described,and the characteristics of EGR system are analyzed.Then combined with the characteristics of pulse converter,we propose using pulse converter to improve EGR rate.Simulation analysis and test demonstrate the effect of pulse converter on increasing EGR rate and reducing fuel consumption rate of engine.
