Abstract
A control valve arrangement for a three-valve-per-cylinder internal combustion engine that redirects the flow through a siamese-type intake passage when in its closed position so as to generate a higher velocity to the intake charge and redirect the flow so as to generate turbulence in the combustion chamber. A number of embodiments of control valves are disclosed, each being of the plate-type and being mounted in a generally oval intake passage on a control valve shaft in such a way that the control valve shaft provides minimum obstruction to the flow through the intake passage, regardless of its position.
