An exhaust valve actuation system utilizes pressurized air provided by an air compressor and controlled by signals from a controller, such as an engine control module. The pressurized air is directed by a pressure valve that operates under the control of the controller and the exhaust valve is thus moved as a function of a preselected parameter monitored by the engine control module. The pressure valve can operate in a two position manner or a multi position manner, depending on the particular embodiment of the present invention utilized.
