Claims (1)
至る独立吸気通路と、該各独立吸気通路から分岐
し、該各独立吸気通路を相互に連通する連通部と
、該連通部と各独立吸気通路とをエンジンの運転
状態に応じて連通あるいは遮断する通路切換弁と
を備えたエンジンの吸気装置において、 上記通路切換弁に、該切換弁の閉時における上
流側、下流側の圧力差を緩和する差圧緩和開口を
設けたことを特徴とするエンジンの吸気装置。[Scope of Claim for Utility Model Registration] An intake expansion chamber, an independent intake passage extending from the intake expansion chamber and reaching each cylinder, and a communication portion that branches from each independent intake passage and communicates each independent intake passage with each other. , an intake system for an engine comprising a passage switching valve that communicates or cuts off communication between the communication portion and each independent intake passage depending on the operating state of the engine, wherein the passage switching valve has an upstream side when the switching valve is closed. An intake device for an engine, characterized in that it is provided with a differential pressure relief opening that alleviates a pressure difference on the downstream side.
