抄録

Biomass resources are drawing more and more attention as alternative fuel for combating the energy crisis and for atmospheric environment protection. The small gas engine in a distributed power generation system is an efficient system to use, because the biomass resource is stored in large area and its energy density is low. The heat quantity of gas fuel converted from biomass is low, and the gas composition is affected by the source type, the gasification method, and the gasifying condition. Therefore, the gas engine must be modified and operated stably with high thermal efficiency in view of these fuel fluctuations. In this study, we aim to develop a small gas engine system for biomass gas by modifying the control system of a conventional spark ignition engine. The engine control system for the biomass gas that was developed analyzed the fuel type in real time by measuring the in-cylinder gas pressure. With this control system, stable automatic engine operation was successfully achieved under different fuel composition percentages of methane and the mock biomass gas.
