EGR Control Logic Design and Control MAPs Calibration for a High -Pressure Common Rail Diesel Engine
Abstract：In order to meet the emission regulation limits and to reduce fuel consumption as far as possible, the EGR control logic was designed. An combined feed -forward control and closed - loop control were used in the EGR control system. The amounts of fresh air were set as the input in the outer control loop, and EGR valve opening values were calculated on - line so as to regulate EGR rate indirectly. EGR control MAPs were calibrated by means of the diesel engine emission test, and the EGR control tests were conducted. The results show that the EGR control logic operates stably and control parameters are easy to calibrate.
