摘要： A turbine impeller includes: a hub portion coupled to an end of a rotational shaft; a plurality of main blades disposed at intervals on a peripheral surface of the hub portion; and a short blade disposed between two adjacent main blades among the plurality of main blades. An inter-blade flow channel is formed between the two adjacent main blades so that a fluid flows through the inter-blade flow channel from an outer side toward an inner side of the turbine impeller in a radial direction. In a meridional plane, a hub-side end of a leading edge of the short blade is disposed on an inner side, in the radial direction, of a hub-side end of a leading edge of the main blade.

摘要： In a turbine rotor blade of a radial turbine, especially in a variable-geometry turbine with variable nozzles, an object is to restrict high-order resonance of the turbine rotor blade without increasing the size of a device with a simplified structure. A plurality of turbine rotor blades 3 for a radial turbine is disposed on a hub surface. Each turbine rotor blade 3 includes blade-thickness changing portions 41, 42 at which at least a blade thickness of a cross-sectional shape at a middle portion 3e of a blade height increases rapidly with respect to a blade thickness t1 of a leading-edge side, at a predetermined position from a leading edge 3a along a blade length which follows a gas flow from the leading edge 3a to a trailing edge 3b. The blade thickness increases to a blade thickness t2 via the blade-thickness changing portions.

摘要： A turbocharger includes: at least two scroll passages, and a first range of the nozzle flow passage into which the exhaust gas flowing through the first scroll passage is introduced does not overlap with a second range of the nozzle flow passage into which the exhaust gas flowing through the second scroll passage is introduced, in a circumferential direction of the nozzle flow passage. The first scroll passage includes: a division wall disposed along a flow direction of the exhaust gas within a predetermined range in the first scroll passage, the division wall dividing the first scroll passage into a radially outer side scroll passage and a radially inner side scroll passage positioned on a radially inner side of the radially outer side scroll passage, and having a communication hole which brings the radially outer side scroll passage and the radially inner side scroll passage into communication; and a flow-rate control valve disposed on an upstream side of the division wall, for adjusting a flow rate of the exhaust gas flowing through the radially outer side scroll passage and the radially inner side scroll passage.

摘要： An object of the invention is to provide a scroll structure of a turbine housing of a twin scroll turbocharger of which flow-through abilities of two exhaust gas passages are equal to each other. A tongue (44), which partitions a scroll portion (26) into an outer peripheral portion (26a) and an inner peripheral portion (26b) in a longitudinal section parallel to a flow direction of an exhaust gas, is formed at the turbine housing (32), the tongue (44) includes a front-side tongue (46) and a rear-side tongue (48) that respectively close the two exhaust gas passages at the outer peripheral portion (26a) in a cross-section, and respective inner sides (46a, 48a) of the front-side tongue (46) and the rear-side tongue (48) and respective minimal outflow width portions (56a, 58a) of a front-side passage (22) and a rear-side passage (24) are formed substantially parallel to each other in the cross-section at a downstream end of the outer peripheral portion (26a).

摘要： Providing a turbine wheel that includes, but not limited to: a plurality of blade parts and a scallop cut-out profile, the scallop cut-out profile being formed by cutting-out the back side wall part of the turbine wheel between the suction surface side of a blade part and the pressure surface side of the adjacent blade part, wherein the leakage flow on the rear side of the blade part is constrained so as to enhance the turbocharger efficiency. Providing the blade part 5 (i.e. the area between the scallop parts on the tip end side of the blade part) with the suction surface side extended part 25 in the neighborhood of the suction surface 21 of the blade part so that the thickness of the blade part on the tip end side of the scallop cut-out profile is increased; or, the pressure surface side extended part 32 in the neighborhood of the pressure surface 19 of the blade part so that the thickness of the blade part on the tip end side of the scallop cut-out profile is increased. Or, the positive/suction surface side extended parts are provided. Thereby, the extended width of the extended part is formed so that the width is an almost constant width along the camber line of the blade part from the tip end side to the root side of the blade, the projecting-out width part forming a strip area.

摘要： A two-stage turbo system includes: a high-pressure stage turbocharger having a high-pressure stage turbine disposed in an exhaust passage of an engine; and a low-pressure stage turbocharger which includes a low-pressure stage turbine disposed downstream of the high-pressure stage turbine in the exhaust passage, and which is larger in size than the high-pressure stage turbocharger. The low-pressure stage turbine includes at least two scroll passages including a first scroll passage and a second scroll passage, which together form a scroll part for introducing exhaust gas into a nozzle flow passage of the low-pressure stage turbine. The scroll part is configured such that a first range of the nozzle flow passage into which the exhaust gas passing through the first scroll passage is introduced does not overlap with a second range of the nozzle flow passage into which the exhaust gas passing through the second scroll passage is introduced, in a circumferential direction of the nozzle flow passage.
