Abstract
A turbine housing system that includes a housing that is formed as a single casting and includes a pair of identical first and second scroll volute passages separated by a center wall that each provide a reducing cross section therealong through approximately three hundred sixty (360) degrees from an inlet end that connects to a source of engine inlet exhaust gas to an inlet throat of a turbine chamber wherein a turbine wheel is journaled to be turned by the entering inlet exhaust gas. An expansion chamber is provided to receive spent exhaust gas from the turbine chamber that is connected to a manifold to vent those spent gases to atmosphere. The housing further includes a turbine chamber bypass section that is open between one of the first or second passages and into the expansion chamber and includes a valve seat formed across the turbine chamber bypass section that is closed over by a valve head of a waste gate valve. The waste gate valve is mounted in the housing, such that a valve head thereof will lift off the valve seat should the pressure of the inlet exhaust gas exceed a maximum pressure, thereby opening the turbine chamber bypass section to pass inlet exhaust gas into the expansion section, so as to reduce the pressure differential across the turbine wheel, thereby reducing the speed of turbine wheel turning.
