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.

Air induction system having bypass flow control

A system for removing particulates from a filtering device of a machine. The system may include a flow assembly configured to direct a flow of gas through the filtering device, with one or more elements of the flow assembly being removably attached to a first opening of the filtering device. The system may also include a sound generation assembly configured to direct sound waves toward the filtering device to remove particulates from the filtering device.
