機関の吸気装置。[Scope of Claim for Utility Model Registration] (1) An upstream intake passage that guides fresh air from the air cleaner, a fuel supply device having an intake passage extending substantially perpendicular to the upstream intake passage, and a connection to the fuel supply device. an intake manifold having a plurality of branch passages; an intake chamber having an inlet connected to an upstream intake passage; and an outlet connected to an intake passage of a fuel supply device; In an intake system for an internal combustion engine in which the outlets are opened in directions substantially perpendicular to each other, the outlet is formed at a location offset from an imaginary extension of the axis of the inlet, and the inlet is located within the intake chamber. An intake system for an internal combustion engine, characterized in that it is provided with a baffle plate that impinges on and causes turbulence in the intake air flow flowing from the engine. (2) The baffle plate has a baffle plate portion 61 that is substantially perpendicular to the imaginary extension of the axis of the inlet and faces the projection plane of the inlet, and a baffle plate portion 61 that is outside the projection plane of the inlet. baffle plate portions 63 in different directions, and arranged so as to divide the inside of the intake chamber into an inlet side space and an outlet side space, and a location where the baffle plate portion 63 is located outside the projection plane of the inlet. The space that communicates the inlet side space and the outlet side space is smaller than the space that communicates the inlet side space and the outlet side space at the location where the baffle plate portion 61 facing the projection plane of the inlet is located. The intake system for an internal combustion engine according to claim 1, wherein the intake device is also large in size.
