Abstract
The objective of this study is to develop a small size and high thermal efficiency biomass gas engine. Biomass gas has component fluctuation, which arises from resources, gasification method, and gasification condition. The engine controller is needed to absorb its fluctuation for high thermal efficiency and stable operation. In this study, the engine control system for biomass gas was developed, which could analyze fuel component in real time by measuring in-cylinder gas pressure. By using this control system, automatic engine operation was succeeded to be stable operation under fuel composition changed from methane to simulated biomass gas.
