Abstract
A multicylinder internal combustion engine has an intake port for each cylinder, with the flow through the intake port being controlled by a port throttle having a sliding plate mounted normally to the longitudinal axes of the intake ports and having windows which may be selectively indexed with the intake ports so as to direct charge air either symmetrically or asymmetrically into the cylinders.
