Turbine end intake structure for turbocharger, and turbocharger comprising the same

A turbine end intake structure for a turbocharger includes a turbine housing, a turbine having multiple blades and located in a turbine shell, and thermal insulation located between the turbine end of the turbocharger and another part. A flow-guiding channel for engine exhaust gases is provided on the turbine housing in communication with the interior of the turbine housing. An inner surface of the turbine housing matching peripheral edges of the blades is a cylindrical surface coaxial with the turbine, while the shape of the peripheral edges of the blades follows the cylindrical surface. Angle-cut portions are provided on the blades at positions corresponding to an intake port of the flow-guiding channel. The thermal insulation has an outwardly extending flow-guiding part, and a flow-guiding path for engine exhaust gases formed by the flow-guiding channel and the flow-guiding part is perpendicular to the angle-cut portions of the blades.
