With the increasing use of gas fuel resource specially natural gas at domestic and abroad, the gas engine fueled by natural gas, liquefied petroleum gas （LPG） and biogas is more widely used than ever. The technology of gas engine has been constantly improved and promoted. Compared with tradition gasoline and diesel engine, the gas engine fueled by the different fuel has different ignition mode, combustion state, and the lubrication requirements are also different. In oil market, the major lubricant company with OEM demand provides special gas engine lubricant suitable for different gas engine and different application situtation. The domestic and abroad gas engine market situation, development status and performance features of gas engine oils were discussed.随着国内外气体燃料资源特别是天然气资源的利用日益受到重视，促使以天然气、LPG以及沼气等气体燃料的燃气发动机的使用越来越广泛，燃气发动机技术也得到了不断改进、提升。相比传统的汽、柴油发动机，由于燃料的不同造成发动机点火方式、燃烧状态等多种不同，对润滑的要求也不相同，国际油公司都结合OME的需求推出了适用不同气体类型以及不同应用场合的各类燃气发动机的专用润滑产品。介绍国内外气体燃料发动机的市场现状、技术发展以及相适应燃气发动机油的其性能特点。
