Abstract
A control system for a gaseous-fueled engine is disclosed. The gaseous-fueled engine may have an intake valve mechanically driven by a camshaft. The control system may have a variable valve timing device configured to adjust a cyclical opening and closing timing of the intake valve. The control system may further have a sensor configured to generate a signal indicative of a speed of the engine and a controller in communication with the variable valve timing device and the sensor. In addition, the controller may be configured to selectively initiate a first Miller Cycle timing and a second Miller Cycle timing based on the signal.
