      Abstract: In order to assist advanced combustion research, this project is based on the euro 4 heavy-duty diesel engine, maintain the same high pressure EGR system, set up various options of low pressure EGR systems, under the combined effect of the high / low pressure EGR system EGR rate of 50% target simulation, and ultimately determine a feasible solution, and experimental verification of the program.

      Key Words: high pressure; low pressure; EGR; simulation; testendprint
