Claims

[Scope of utility model registration request]

An exhaust gas flow path surrounding the turbine wheel is formed in the turbine housing of the exhaust turbo supercharger main body, and the exhaust gas flow path is formed into first and second flow paths on the inner wall surface of the turbine housing. A dividing partition wall is provided, and exhaust gas discharged from the plurality of cylinders of the engine is introduced into each of the first and second flow paths of the turbine housing through the first and second exhaust passages, In an exhaust turbo supercharger in which exhaust gas is blown onto the turbine wheel from each of these first and second flow paths to drive the turbine wheel to rotate, the partition wall is formed of a plate material, and the partition wall is made of a cast material. An exhaust turbo supercharger characterized in that the flat partition wall is provided on an inner wall surface of a housing, and an extension portion extending to the vicinity of the turbine wheel is provided at an inner peripheral edge of the partition wall.
