ABSTRACT:
The runners of the intake manifold between the fuel-air mixture device and the valve ports of the head of an internal combustion engine are tuneable to a particular engine and/or RPM range either manually or automatically by moving at least one wall of each runner inwardly and outwardly to correspondingly decrease and increase the flow through cross-sectional area along the runner. Manual adjustments may be made for particular running conditions or engine component combinations, and automatic adjustments may be made in correspondence with changes in engine speed during operation by vacuum controls, throttle linkage, or electrical controls, for example.
