Biomass resource draws more and more attentions as an alternative fuel for energy crisis and atmospheric environment protection. The small size gas engine in a distributed power generation system is an efficient system to use it because biomass resource is stored in large area and its energy density is low. However, calorie of gas fuel converted from biomass is low, and gas composition is affected by resource, gasification method, furthermore, gasifying condition changes its composition momentarily during engine operation. So, gas engine needs to be operated stably and with high thermal efficiency under these fuel fluctuations. 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. The engine control system for biomass gas was developed, which could analyze fuel component in real time by measuring in-cylinder gas pressure. With this control system, automatic engine operation was succeeded to be operated stably under different fuel composition percentage changing from methane to the simulated biomass gas.
