二次空気を導く二次空気導入装置において、排気
ガス流を間欠的に遮断して排気ガスを圧縮し、圧
縮した排気ガスを排気管の二次空気導入口上流側
へ排出する排気ガス流調整装置と、この排気ガス
流調整装置から排出する排気ガスの排出量をエン
ジンの運転状態に応じて制御し二次空気導入口近
傍の排気管内の圧力を変化させる制御手段とを有
することを特徴とする二次空気導入装置。 In a secondary air introduction device that guides secondary air into the exhaust pipe between the engine and the catalytic converter, the exhaust gas flow is intermittently interrupted to compress the exhaust gas, and the compressed exhaust gas is transferred to the secondary air in the exhaust pipe. The system includes an exhaust gas flow regulating device that discharges upstream of the inlet, and controls the amount of exhaust gas discharged from this exhaust gas flow regulating device according to the operating condition of the engine to control the pressure in the exhaust pipe near the secondary air inlet. A secondary air introduction device characterized by having a control means for changing the secondary air introduction device.
