ABSTRACT:
Adjacent expansible chambers of an engine are provided with an intake runner set employing at least three runner passages conducting the working fluid from a common plenum to the expansible chambers, with at least one of the runners only serving one of the expansible chambers, at least another of the runners serving only the other expansible chamber, and at least still another of the runners commonly serving both of the expansible chambers. Preferably, a flow control is provided for one or more of the runners, preferably the common runner to manually or automatically control the flow of fluid through the common runner. Thereby, the runners for the expansible chambers may be adjusted in effective cross sectional area for tuned efficiency at different speeds. Preferably, such runners extend through the intake manifold and head ports without communication throughout their extent.
