摘　　要：在我国 ,天然气汽车已被很多大城市作为治理城市大气污染的重要措施。我国正在实施的“西气东输”工程将大大促进天然气管道沿线各大中城市广泛使用天然气汽车。天然气发动机技术是决定天然气汽车性能的核心因素 ,对于不同要求的排放法规可以采用相应的发动机技术。文章着重分析国内外天然气发动机的不同燃料供给系统的技术特点、发动机性能特点及其技术发展状况。并分别对火花点火天然气发动机 ,包括汽油—天然气两用燃料发动机和单燃料天然气发动机 ,以及压燃天然气发动机 ,包括常规双燃料天然气发动机和微引燃天然气发动机的控制系统和发动机工作性能进行了详细说明。最后 ,文章还简要介绍了高压缸内直喷技术和发动机排气催化净化技术等天然气汽车新技术。The utilization of natural gas vehicle s has been taken as an important measure of controlling atmospheric pollution in many big cities in China.The 'West to East Natural Gas Transsion' project,w hich is being carried out at present in China,will greatly promote the utilizati on of natural gas vehicles in each big/medium city sitting along the gas pipeli ne.The core factor of controlling natural gas vehicle properties is the gas eng ine technology which may be relevantly adopted for different exhaust standards.I n the paper,the mechanical properties,techniques and their developing circumstan ces of different fuel supply systems of the domestic and foreign gas engines are emphatically analyzed;then the control systems and work performances of the spa rk firing gas engines,including gasoline natural gas dual fuel engine and sin gle fuel natural gas engine,and the compressed natural gas engines,including con ventional dual fuel natural gas engine and micro ignition natural gas engine,a re stated in detail;and then some novel natural gas vehicle techniques as high p ressure inner cylinder direct jetting technique and engine exhaust catalytic pu rifying techniques,etc.,are briefly introduced.
