This study aims to develop a small size gas engine system with biomass gas by modifying the control system of a conventional spark ignition engine. In this paper, combustion characteristics of typical biomass gas assuming the wood chip pyrolysis gas, whose lower heating value was about 1/6 of the city gas in Japan, were investigated. Engine control system for biomass gas was also examined. It was confirmed that simulated biomass gas could achieve high thermal efficiency and stable combustion for wide range equivalence ratio without knocking and at low emissions. Automatic engine operation with real time in-cylinder gas pressure analysis was also tried under fuel composition change.
