In order to use biomass resources efficiently, a small-size gas engine in a small-distributed generation system is one of the effective methods. However, existing gas engines for energy generation are too big to use in small-distributed generation systems and very expensive. So, diverting automotive engines is sensible solution because of their low cost. On the other hand, the composition of biomass gas generated from gasification plants is affected not only by the source and the gasification method but also by the gasification condition. Therefore, we aimed to develop a low cost and small size biomass gas engine by diverting an automotive engine with original control system. The intake system of the automotive gasoline engine was changed to two throttles in order to control both fuel and air flow rate respectively. The control system was constructed by assuming to use various fuels whose composition can fluctuate. Operational test was carried out by using real biomass gas from the gasification plant. As results, engine speed and air fuel ratio were stably controlled and the engine output achieved 19 kW.
