Claims (1)
燃機関に至る吸気通路中に、排気ターボ過給機等
の過給機を設けると共に、該過給機より下流側に
スロツトル弁を設け、前記大気空気の吸入管に対
して、排気マニホールドを覆うヒートプロテクタ
等の暖気発生部からの暖気導入管を接続する部分
に、圧力作動式の暖気切換弁を設けて成る過給式
内燃機関において、前記圧力作動式暖気切換弁に
は、前記暖気導入管を閉に保持するばねを設ける
一方、その圧力室に、前記過給機と気化器との間
における吸気通路からの圧力伝達通路を、当該吸
気通路内の圧力によつて暖気切換弁が前記ばねに
抗して暖気導入管を開くように接続し、且つ、前
記圧力伝達通路には、前記過給機より下流側の暖
気温度が低いときにおいてのみ当該圧力伝達通路
を連通するようにした温度感知弁を設けたことを
特徴とする過給式内燃機関における吸気装置。 A supercharger such as an exhaust turbo supercharger is provided in the intake passage leading from the air cleaner equipped with an atmospheric air intake pipe to the internal combustion engine, and a throttle valve is provided downstream from the supercharger to remove the atmospheric air. In a supercharged internal combustion engine, a pressure-operated warm air switching valve is provided in a part where a warm air introduction pipe from a warm air generating unit such as a heat protector that covers an exhaust manifold is connected to an intake pipe. The warm air switching valve is provided with a spring that holds the warm air introduction pipe closed, and a pressure transmission passage from the intake passage between the supercharger and the carburetor is connected to the pressure chamber in the intake passage. The warm air switching valve is connected to open the warm air introduction pipe against the spring by pressure, and the pressure is applied to the pressure transmission passage only when the temperature of the warm air downstream of the supercharger is low. An intake device for a supercharged internal combustion engine, characterized in that it is provided with a temperature sensing valve that communicates with a transmission passage.
