ールエンジンの燃焼用空気供給装置。[Claims for Utility Model Registration] In a methanol engine equipped with an oxidation catalyst device in the middle of the exhaust pipe, the inlet of the oxidation catalyst device and the intake manifold of the engine are communicated, and the outlet of the oxidation catalyst device and the intake manifold are connected to each other. The oxidation catalyst device is provided with a switching means for communicating with the manifold and for switching the intake manifold to communicate with either the inlet portion or the outlet portion, and temperature sensors are provided in each of the inlet portion and the outlet portion. An exhaust gas circulation valve is provided, which measures the inlet and outlet temperatures of the intake manifold, and switches the intake manifold between a state in which it is not communicated with both the inlet and the outlet, and a state in which it is communicated with the intake manifold. A combustion air supply device for a methanol engine, characterized in that one or both of the inlet exhaust gas and the outlet exhaust gas of the oxidation catalyst device is introduced into the intake manifold by the switching means according to the exhaust gas temperature.
