Abstract
An example induction system for an engine includes a plenum in fluid communication with multiple primary runners. A plenum valve is arranged between first and second chambers of the plenum, which are respectively in fluid communication with first and second sets of the primary runners. The plenum valve is configured to move between open and closed positions and regulate flow between the first and second chambers. A second runner is arranged upstream from and in fluid communication with the plenum. A runner valve is arranged in the secondary runner and configured to vary the amount of flow through the secondary runner. A common actuator is interconnected to both the plenum and runner valves and is configured to move both of the plenum and runner valves between desired positions to achieve desired valve configurations that tune the engine.
