機関の排気対策装置。A passage is connected to an upstream intake pipe and a downstream intake pipe of an intake throttle valve in the carburetor, and an afterfire prevention valve is provided in the middle of this passage in response to instantaneous pressure fluctuations in the downstream intake pipe. In an internal combustion engine configured to prevent afterfire by introducing fresh air when the afterfire prevention valve opens, the exhaust pipe communicates with the downstream intake pipe. An exhaust gas countermeasure device for an internal combustion engine, characterized in that a recirculation passage is provided, and an exhaust return valve that opens in conjunction with the afterfire prevention valve is provided in the middle of the exhaust recirculation passage.
