Abstract
An apparatus for controlling the exhaust timing of a two-cycle engine. A control valve is provided for adjusting the position of the top of the control port in the two-cycle engine as a function of the engine speed. A central processing unit receives a signal from an engine speed detector indicating the engine's operating speed. Based upon a control map, the central processing unit initiates action to adjust the position of the control valve.
