The composition of natural gas varies with the location and climate. However, the effects of differences in fuel composition has not been considered in the development of natural gas engine. The purpose of this study is to investigate the effect of composition of natural gas on engine performance and to provide basic data for the development of natural gas engine and the selection of gas imports. As a result, when the Air/Fuel ratio was controlled with fixed spark timing, the variation of maximum power for six different gas fuels was less than 3%, and when the spark timing was controlled with fixed fuel volume, that was less than 7%.<br/>
