Abstract
A number of embodiments of intake passages for internal combustion engines wherein it is possible to obtain a tumble and tumble and swirl action or both under some running conditions and substantially unrestricted flow under high speed conditions so as to improve volumetric efficiency while, at the same time, increasing turbulence under the conditions when the flow pattern is altered. The flow pattern is controlled by a rectifier plate which extends through at least one of the intake passages and divides it into two flow areas, one of which is closed by a control valve which engages the rectifier plate in its flow controlling position so as to provide a stop for the control valve. The control valve is configured and oriented so as to provide substantially unrestricted flow paths in each of its positions. Embodiments incorporating carbureted and fuel injected engines are depicted.
