AbstractFacing the inevitable declining resources of energy,the studies of alternative fuel have obvious significance.In this paper,methane is used as main fuel with a small quantity pilot injection through the diesel fuel system.A combustion models of methane-diesel dual fuel engine (DFE) are developed,which includes thermodynamic-kinetic combustion model,heat-transfer and multi-zone combustion sub-model for pilot.By using those models,the combustion process and influence of operating parameters on dual fuel engine performance and emissions were predicted.
