The invention is in a double chambered turbine housing and seal that includes separate exhaust gas inlet and exhaust chambers and a turbine chamber (11) and (12) combined in a single housing (10), and provides a ball segment (29) that is secured to an exhaust inlet line (28) for telescoping within an open collar end (13) of the inlet chamber, the exhaust inlet line interior wall and collar inner surface to align so as to minimize a production of turbulence in an exhaust gas flow therethrough, which inlet chamber (11) from the collar (13) maintains a constant cross-section through a dogleg bend to a throat (14) of a scroll volute (15), the inlet chamber walls angled uniformly through the dogleg bend to minimize a creation of turbulence in that flow. The inlet chamber is formed from the scroll volute throat to have a uniform cross-sectional reduction, so as to reduce an exhaust gas flow volume traveling therein, and proportionally increase the pressure of that flow without a creation of turbulence, the volute ending in a throat (16) of a turbine chamber throat (17). The turbine chamber (17) is to contain a turbine wheel (18) journaled to turn therein of an exhaust gas turbine air compressor (19l ) that provides a compressing fresh air flow for combining with fuel and burning in an internal combustion engine.

A double chambered turbine housing comprising, in a single cast housing, independent inlet and exhaust chambers, said inlet chamber for passing vehicle exhaust to a turbine chamber, with vehicle exhaust passed from said turbine chamber traveling through said exhaust chamber into said vehicle exhaust

A double chambered turbine housing comprising, in a single cast housing, independent inlet and exhaust chambers, said inlet chamber for passing vehicle exhaust to a turbine chamber, with vehicle exhaust passed from said turbine chamber traveling through said exhaust chamber into said vehicle exhaust system, said inlet chamber having a first open end for coupling to an exhaust inlet line from a vehicle exhaust manifold for passing exhaust gas therethrough and includes seal means at said first open end for prohibiting exhaust gas leakage at said coupling, said inlet chamber from said first open end, having smooth interior walls that are angled uniformly through a dogleg bend across the exhaust chamber and has a uniform cross-section to an open throat of a scroll volute portion of said inlet chamber, which scroll volute has smooth interior walls that taper uniformly around the scroll to an inlet throat of said turbine chamber, which turbine chamber is formed between said inlet and exhaust chambers and is open across one face to receive a turbine wheel of a conventional exhaust gas driven turbine air compressor journaled to turn therein, said housing opening into said turbine chamber is arranged for mounting said exhaust gas driven turbine air compressor thereto, which said turbine chamber opens through an exducer bore into a first expansion section end of said exhaust chamber, the other or second exhaust end of which exhaust chamber is arranged for connection to an exhaust line of a vehicle exhaust system, and said first open end of said inlet chamber and said exhaust end of said exhaust chamber are alongside one another; means for mounting said exhaust gas driven turbine air compressor to said housing; and means for coupling said second exhaust end of which exhaust chamber to said vehicle exhaust line.
