Taking a diesel engine as a prototype, the intake port gasoline injection system was added to realize the combustion mode that the fuel ignited by premixed injection of gasoline in intake port and direct injection of diesel oil in cylinder, and the performance of gasoline/diesel dual-fuel engine was deeply studied. The results shows: 1. The peak in-cylinder combustion pressure and heat release rate of gasoline/diesel dual-fuel engines gradually decrease with the increase of gasoline/diesel ratio; 2. The fuel consumption acquires optimal value at 65% of gasoline/diesel rate; 3. Both NOx emission and Soot emission decrease and got significantly low value with the increase of gasoline/diesel ratio. So it can be concluded: the increase of EGR rate make combustion pressure peak in-cylinder and heat release rate peak firstly rise and then decrease. Meanwhile, CA50 shows the trends of advancing first and retarding then. Low EGR rate promotes NOx emission and high EGR rate restrains NOx emission. And EGR rate has little impact on Soot.
