Abstract
An air induction system for a power system is provided having a compressor operable to compress air directed into an engine. In addition, the air induction system has a throttle valve disposed between the compressor and the engine, the throttle valve being configured to selectively restrict the flow of compressed air into the engine. The air induction system also has a recirculation valve disposed between the compressor and the throttle valve, the recirculation valve being configured to selectively divert a portion of the flow of compressed air. Furthermore, the air induction system has a controller configured to actuate the recirculation valve in response to a pressure differential between air upstream of the throttle valve and air downstream of the throttle valve.
