摘要： A control system for an engine includes a restriction determination module and a valve control module. The restriction determination module determines a desired exhaust back pressure of the engine based on an exhaust flow rate of the engine. The valve control module selectively adjusts a valve position of an exhaust valve that restricts an exhaust flow of the engine based on the desired exhaust back pressure. The exhaust valve may include a valve body, a throttle plate, and an annular protrusion coupled to an inner surface of the valve body and protruding towards the throttle plate. The annular protrusion may abut a side of the throttle plate and may restrict fluid flow through an annular space between the throttle plate and the inner surface when the throttle plate is positioned in a rotational position transverse to a direction of fluid flow. A related method is also provided.
