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 proc esses 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 base d on the results of engine bed testing.The effect of the engine is satisfying.
