ABSTRACT:
A valve arrangement for an internal combustion engine is disclosed. The valve arrangement may have a housing at least partially defining a venturi passageway, a first port disposed at an entrance to the venturi passageway, and a second port disposed at a throat of the venturi passageway. The valve arrangement may further have a valve element disposed within the housing to regulate the flow of fluid through the housing, and a sensor mounted to the housing in communication with the first and second ports. The valve arrangement may also have a controller mounted to the housing in communication with the sensor. The controller may be configured to affect movement of the valve element in response to input from the sensor.
