を特徴とするエンジンの２次エア供給装置。 A secondary air passage for introducing secondary air from the air cleaner is provided, and a switching valve is installed near the air intake port of the air cleaner to switch between sucking hot air when the air is cold and sucking cold air when the air is warm. The air supply device includes: a cold secondary air inlet for introducing cold secondary air into the secondary air passage; a hot secondary air inlet for introducing hot secondary air into the secondary air passage; Equipped with a control valve that is linked to the switching valve and opens the hot secondary air inlet and closes the cold secondary air inlet when the air is cold, and opens the cold secondary air inlet and closes the hot secondary air inlet when the air is warm. A secondary air supply device for an engine, characterized in that the opening area of the hot secondary air inlet is set larger than the opening area of the cold secondary air inlet.
