摘　　要：以天然气为主要燃料、少量柴油为引燃油的双燃料发动机为研究对象 ,建立燃烧模型 ,它包括热力学、化学反应动力学、引燃油多区传热和燃烧模型。应用该模型预算了双燃料发动机的燃烧过程 。Facing 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.
