Claims (1)
通路内に２次空気を供給するようにした２次空気
供給制御装置において、燃料供給系に異常がある
か否かを判別する異常判別手段を具備し、該異常
判別手段の判別結果に基いて燃料供給系に異常が
あるときには機関の運転状態にかかわらずに２次
空気の供給を停止するようにした内燃機関の２次
空気供給制御装置。 A secondary air supply control device configured to supply secondary air into an engine exhaust passage during a predetermined engine operating state, comprising an abnormality determining means for determining whether or not there is an abnormality in the fuel supply system. A secondary air supply control device for an internal combustion engine is configured to stop the supply of secondary air regardless of the operating state of the engine when there is an abnormality in the fuel supply system based on the determination result of the abnormality determining means.
