摘　　要：应用AVL BOOST软件建立了氢燃料内燃机在稀燃状况下的计算模型,并在不同燃空当量比和点火时刻下,对氢内燃机燃烧过程进行了数值模拟,模拟结果和试验结果吻合较好。在此基础上,进行了点火提前角和燃空当量比对氢内燃机燃烧过程的影响研究,为合理组织氢内燃机的燃烧过程研究提供了依据。This paper establishes a caculation model at lean-operation of hydrogen-fueled IC engine by using AVL BOOST soft,and simulates the combustion process of hydrogen-fueled IC engine at different equivalence ratio and ignition timing, the simulation results agree with the experimental data satisfactorily. On this basis it makes some study on the combustion process of hydrogen-fueled IC engine by changing the ignition advance angle and equivalence ratio of the model. And this provides a basis for reasonable organization combustion process of hydrogen-fueled IC engine.
