Abstract
An integrated inlet manifold tuning valve for a variable configuration air inlet manifold and a charge motion control system. A tuning valve, which is preferably approximately a quarter-barrel valve, is arranged at an end of the low- and high-speed runners at or near an intake port for an internal combustion engine. The tuning valve operates to tune the variable manifold and provide a mixture motion for charge motion control.
