摘　　要：自1872住天然气发动机问世，三十年代初由意大利人率先采用天然气作为汽车燃料：七十年代燃气汽车技术逐渐发展；九十年代后天然气汽车数量迅速增加。目前，两用燃料单点喷射系统和单一燃料（天然气或液化石油气）闭环多点顺序喷射系统相继问世，而闭环多点顺序喷射系统是当今燃气发动机电控技术发展的主流和方向。On March 13, the ceremony of put out into market was held in DiaoYuTai in Beijing, for the first set of large power engine in China, a cylinder internal High Pressure Direct Injection pressure ignition natural gas engine （＂ HPDI Engine ＂ for short）. This technical innovation fruit is put out by the Westport New Energy Power Engine Co., Ltd., Weichai Power. The successful development of this project has filled in blank in the application field of natural gas cylinder internal direct injection engine, which will be a milestone in the development history of natural gas engine in China.
