とを空気通路を以つて連結し、機関がアイドル状
態であり、かつ各気筒の吸排気弁のオーバラツプ
時より以前に開弁開始して上記吸気通路と各吸気
ポートとを連通する制御弁を各吸気ポートに対応
して夫々１個上記空気通路内に介装した空気供給
装置付内燃機関において、上記空気通路を連通・
遮断する上記制御弁の弁体を、上記吸排気弁を作
動させるカムシヤフトで駆動させたことを特徴と
する、空気供給装置付内燃機関。 The intake passage upstream of the throttle valve and each intake port are connected by an air passage, and when the engine is in an idling state and the valves start opening before the intake and exhaust valves of each cylinder overlap, the intake passage is connected to the intake passage. In an internal combustion engine with an air supply device in which one control valve is interposed in the air passage corresponding to each intake port, the air passage communicates with the air passage.
An internal combustion engine with an air supply device, characterized in that the valve body of the control valve that shuts off is driven by a camshaft that operates the intake and exhaust valves.
