特徴とする内燃機関の吸気装置。The engine intake passage consists of a main intake passage in which a second throttle valve is interposed downstream of the intake throttle valve, and a sub-intake passage that bypasses the second throttle valve, and intake air flows into the cylinder from the sub-intake passage. In an intake system for an internal combustion engine that generates a swirl, a tournament-type intake manifold is provided with a collector portion where two branch portions come together, and the passage cross-sectional area of this collector portion is expanded and a recess is provided in the bottom wall. An intake system for an internal combustion engine, characterized in that a second throttle valve is interposed in the main intake passage downstream of the collector portion, and the upstream end of the auxiliary intake passage opens into the recess.
