| Abstract: | For the EGR system of electronically controlled diesel engine,the EGR control was deeply analyzed and researched.The control logical algorithms of EGR activation,EGR intake demand calculation,EGR intake control and EGR valve position control were designed.The EGR control strategy diagram was compiled and simulated offline with MATLAB/Simulink software and finally was tested on the hardware testing platform.The results show that the control effect agrees with the anticipation,which realizes the EGR control o... |
