Abstract

PURPOSE: To improve heat insulation by forming a scroll of a turbine housing in a specific design.
CONSTITUTION: A turbine housing, made up of a turbine housing wall 8 and an insulating sheet metal scroll member 10 between which a clearance 9 is given, includes a scroll 6 enclosing a turbine impeller 1 and a throat 7 of an exhaust inlet tangently leading engine exhaust into the scroll 6. The double-wall housing has efficient heat insulation. Exhaust at high speed sent from an upstream exhaust passage 12 into the scroll 6 through the throat 7 is swirled along the internal wall of the scroll 10 to turn the turbine impellers 1. When fed out into the downstream exhaust passage 11, the clearance 9 permits lower exhaust heat to be emitted to the turbine housing wall 8.
