摘要： An air induction system for an engine is disclosed. The air induction system has a compressor operable to compress air directed into the engine, a bypass valve, and a throttle valve. The bypass valve may be disposed between the compressor and the engine and may have a valve element movable to selectively divert a portion of the compressed air away from the engine in response to a desired air-to-fuel ratio of the engine. The throttle valve may be disposed between the bypass valve and the engine and may have a valve element movable to selectively restrict the flow of compressed air into the engine in response to a desired air-to-fuel ratio of the engine. The movements of the valve elements of the bypass and throttle valves may be substantially sequential.

摘要： A control system for an engine having a first cylinder and a second cylinder is disclosed having a first engine valve movable to regulate a fluid flow of the first cylinder and a first actuator associated with the first engine valve. The control system also has a second engine valve movable to regulate a fluid flow of the second cylinder and a sensor configured to generate a signal indicative of a pressure within the first cylinder. The control system also has a controller that is in communication with the first actuator and the sensor. The controller is configured to compare the pressure within the first cylinder with a desired pressure and selectively regulate the first actuator to adjust a timing of the first engine valve independently of the timing of the second engine valve based on the comparison.
