摘　　要：由于石油资源的逐渐枯竭和排放法规的日益严格 ,使天然气发动机在全世界得到广泛地发展。文章介绍了由柴油机改制成火花点火式天然气发动机的主要设计过程 ,分析了此类型发动机在改制过程中应注意的几个问题 ,介绍了 412 5天然气发动机的改制特点 ,通过发动机台架试验 ,讨论了该发动机的工作特性 ,其结果是令人满意的。Natural gas engines have widely been developed in the world due to the decrease of oil resources and the strictness of exhaust regulations. This paper introduces the main processes of designing diesel engines fuelled by natural gas and ignited by spark plug, and analyzes a number of problems considered in processes of designing the engines. As an example, the characteristics of a natural gas engine converted from a 4125 diesel engine are introduced,and the performances of the prototype engine are discussed based on the results of engine bed testing.The effect of the engine is satisfying.
