Claims (1)
れ以上の負荷において上記主吸気系と同時に吸気を供給
する副吸気系を、それぞれ独立して同一燃焼室の吸気弁
直上流の個所に連設するものにおいて、上記副吸気系の
気化器下流側と各気筒への吸気通路との連結部に、ダイ
ヤフラム式アクチュエータを備えたロータリバルブから
成る逆流防止装置を設け、主吸気系による吸気の際に上
記ロータリバルブにより副吸気系を遮断することを特徴
とする内燃機関の複式吸気装置。A main intake system that supplies intake air to the combustion chamber under a predetermined load, and a sub-intake system that simultaneously supplies intake air to the main intake system under a load higher than the predetermined load, are installed at locations immediately upstream of the intake valve in the same combustion chamber. A backflow prevention device consisting of a rotary valve equipped with a diaphragm actuator is installed at the connection between the downstream side of the carburetor of the auxiliary intake system and the intake passage to each cylinder, thereby preventing the intake air from the main intake system. A dual intake system for an internal combustion engine, characterized in that the rotary valve shuts off the auxiliary intake system when
