Exhaust turbo-supercharger |
摘要 |
An exhaust turbo-supercharger having a high efficiency is provided. The exhaust turbo-supercharger includes therein an exhaust turbine housing including a spiral channel and a turbine-accommodating chamber connected to an innermost peripheral part of the spiral channel; an exhaust turbine provided in the turbine-accommodating chamber so that the axial line of the exhaust turbine is parallel to that of the spiral channel; a shaft that is concentrically connected to one side of the exhaust turbine in the axial line direction; a bearing housing disposed at the side of the exhaust turbine in the axial line direction so as to be adjacent to the exhaust turbine housing; a bearing that is provided in the bearing housing and that rotatably supports the shaft around the axial line; and a heat shield component interposed between the exhaust turbine housing and the bearing housing. The heat shield component constitutes a part disposed near the entrance of the turbine-accommodating chamber, the part being a part of the inner wall surface of the spiral channel. The part composed of the heat shield component, the part being a part of the inner wall surface of the spiral channel, forms a protruding part protruding toward the inside of the channel relative to an upstream part.
