In order to use the stable biomass resources that exist in rural areas, we have developed a small bio-methane gas engine generator that can be applied to various composition of bio-methane gas. Different from other conventional researches, we added auxiliary devices such as the surge tank, extra carburetor and ECU for our conventional gas engine generator, instead of alteration to the basic structure of the engine and the control method. Referred to the observation data such as the temperature, load and air-fuel ratio, we evaluated adaptability of auxiliary devices for various bio-methane compositions. The surge tank and extra carburetor are useful for getting more air and improve the mix for fuel-air. Along with various composition of bio-methane gas, the ECU could calculate the deviation of desired revolution and current revolution to adjust throttle valve angle by a PID controller, and realize the generator running stable.
