の空燃比制御装置。A gas supply source that stores high-pressure fuel gas is connected to the internal combustion engine and the combustion chamber of the engine through a gas passage, and in this gas passage there is a regulator that reduces the pressure of the fuel gas, and a throttle that mixes the reduced pressure fuel gas and air. A mixer equipped with a valve is provided, a measuring section for measuring the oxygen concentration in the exhaust gas discharged from the combustion chamber, and a valve that opens and closes based on the measurement result of this measuring section, one end of which is connected to the gas passage. A bypass passage connected to the outlet side of the regulator is provided, the valve is installed in the bypass passage, and the other end of the bypass passage is connected to the outlet side of the mixer in the gas passage.
