Abstract
An intake device for an internal combustion engine, in which the intake port is formed to a specific shape without using a partition plate, provided with a valve at its inlet, and the flow direction of intake air to the combustion chambers can be varied by controlling the opening of the valve, thereby providing easy manufacture and reduced cost of the intake port and improved performance when the engine is heavily loaded.
