Abstract

In this paper, in order to obtain performance of marine natural gas/diesel dual fuel engine on exhaust gas recirculation (EGR), the AVL-FIRE software had been adopted to numerical effect analyze of different EGR on combustive process and emission of the engine. The result shows that numerical simulation results are consistent with the tested pressure. The bursts pressure and temperature in-cylinder decrease 4.4% and 5.4% by EGR rate increase every 10%. EGR rate increase make the temperature of the combustion area and the NO generation area in the cylinder decrease, the unburned equivalent ratio increase, the NO emission decrease.
