Claims

[Claims for Utility Model Registration] The intake passage that guides intake air to the intake port of the cylinder head is divided into a primary passage through which intake air flows throughout the entire rotation range of the engine and a secondary passage through which intake air flows mainly in high rotation ranges, spanning almost the entire length of the intake passage. An intake manifold for an engine, the intake manifold for an engine comprising: a spiral plate for generating a swirling flow of intake air flowing through the primary passage near an end of the primary passage on the cylinder head side;
