| Abstract: | Alternative fuel engines have been widely developed in the world due to the decrease of oil resources and the strictness of exhaust regulations. In this paper,the main processes of converting the S195 diesel engine into the engine fuelled with coal-bed gas and ignited by spark plug are described,including the combustion system,the air intake system,the ignition system and the speed governing system. Several issues to be considered in the process of designing the engine are analyzed. The performances of the prototype engine are discussed based on the results of the bench tests. The characteristics of start-up and idle speed of the engine are satisfying. |

| Keywords: | coal-bed gas engine spark igniting start-up characteristic idle speed stability |
