ABSTRACT:
An integral turbine housing and exhaust collector section (44) is disclosed for use in an internal combustion engine turbocharger wherein the integral housing and collector section (44) is characterized by lighter weight, smaller size and greater efficiency than designs known heretofor. In the preferred embodiment, the turbine housing includes a volute section (46) containing twin 360.degree. volute passages (58, 60) into which a pair of parallel exhaust gas streams (34, 36) are directed by a pair of mirror image legs (48, 50) shaped to receive exhaust gases traveling in opposite direction toward the midsection of the engine (25) from a multi branch exhaust manifold (82, 84). Each leg (48, 50) contains a guide passage (81) having a curved central axis (1.sub.4) characterized by a constant radius of curvature (R.sub.1) at each point along the axis (1.sub.4) to provide the most aerodynamically efficient path of travel for each exhaust gas stream (34, 36).
