Numerical simulation of the combustion and emissions of HPDI engine under different natural gas substitution rate was performed using AVL FIRE . The effects of natural gas substitution rate on cylinder average pressure, temperature, heat release rate, NO and Soot were analyzed under four typical conditions. Cylinder average pressure and temperature decrease with increasing natural gas substitution rate. Furthermore, the NO emission will decrease significantly under the same circumstances.
