ABSTRACT:
A number of embodiments of induction system for internal combustion engines employing multiple intake valves. The induction systems are designed so as to provide substantially unrestricted charging and axial flow into the cylinder bore when running under high-speed, high-load conditions. A control valve is provided which changes the effective configuration of the induction passages so as to provide a slant tumble action under lower speed and load conditions. Various arrangements are disclosed for altering the amount of slant action and providing slant actions in opposite or the same direction. In addition, a single control valve element is provided for achieving this effect in a three poppet valve per cylinder engine.
