Claims

[Scope of Claim for Utility Model Registration] (1) Independent intake passages for three or more cylinders are bundled on the upstream side and connected to a collector section having a predetermined volume so that they have the same length up to the resonance tuning point. In the engine intake system, the axial direction of the opening to the collector section which is the upstream end of each of the independent intake passages is the same direction, and the upstream end of each of the independent intake passages is the same direction. An intake device for an engine, characterized in that an inner space surrounded by opposing pipe walls is opened continuously to the collector part to form an extension space of the collector part. (2) In the engine intake system according to claim (1), on one side when viewed from the cylinder row direction of the engine,
An intake system for an engine, wherein each of the independent intake passages and the collector portion of the bundled portion on the upstream side of each of the independent intake passages are provided so as to be oriented in the cylinder row direction.
