As the interest in environmental issues increases, the cogeneration system has recently been attracting much attention. Particularly, the use of medium-sized gas engines for cogeneration systems with low emission and high thermal efficiency is now expected to become widespread. It is likely that biogas and various LNG will be used widely in the future with a view to reducing CO_2 emissions and energy security. It is important to develop gas engines capable of stable operation even when the composition of the fuel gas varies. In this study, we studied the effects of fuel composition on a medium-sized gas engine with a single-cylinder test engine.
