ABSTRACT:
According to the present invention, a system for controlling a runner system in an internal combustion engine is provided which optimizes the available torque output over a broad range of engine speeds. The system generally includes opening or closing a short runner bypass valve system according to changes in engine speed. More particularly, the method comprises sensing a speed of an engine, determining a current open/closed mode of a short runner bypass valve system, calculating a time to a short runner bypass valve system switch point, including compensating for a time period required to switch between open and closed modes, and switching the short runner bypass valve open/closed mode at a given time if the current open/closed mode is not equal to a desired mode.
