Abstract
In a gas engine provided with a gas supply pipe () branching into a supercharger-side gas supply pipe () and a cylinder-side gas supply pipe (), a supercharger-side gas adjusting valve () and a cylinder-side gas adjusting valve () for controlling flow rates of passages, when the gas concentration of the fuel gas changes, the cylinder-side gas adjusting valve is controlled first to keep the output of the gas engine constant and then the supercharger-side gas adjusting valve is controlled to achieve the fuel gas flow rate Qbased on the constant flow ratio by means of a gas supply controller (), while maintaining the flow rate ratio Q/Qat a constant value where Qis a fuel gas flow rate in the supercharger-side gas supply pipe and Qis a fuel gas flow rate in the cylinder-side gas supply pipe.
