摘　　要：拟将一台CA4G22E汽油机改为天然气专用发动机,为此对不同的技术方案进行了模拟计算。计算结果表明,采用增压中冷稀燃方案与理论空燃比方案相比,可以取得很好的动力性与经济性。A CA4G22E gasoline engine is to be refitted as a compressed natural gas (CNG) engine, so simulations were carried out for different system schemes. Simulation results show that the turbo-charged and intercooled lean burn gas engine has higher power output and better fuel economy than the sto-ichiometric burn engine does.
