Abstract
A butterfly valve includes a body with a bore through which exhaust gas may flow and a valve member rotatably mounted within the bore for restricting flow through the bore. A stop extends into the bore to limit movement of the valve member and prevent the valve member from rotating to a closed position. The stop defines a restricted flow position at which the valve member is positioned between an open position and the closed position. An internal combustion engine utilizing the butterfly valve is also provided.
