Abstract

See full text

A variable geometry turbine includes a variable nozzle unit for adjusting a flow of exhaust gas in an exhaust gas passage for introducing exhaust gas to the turbine rotor. The variable nozzle unit includes a plurality of nozzle vanes disposed in the exhaust gas passage at intervals in the circumferential direction of the turbine rotor. When the exhaust gas passage is divided into a near-tongue region in the vicinity of a tongue portion of the scroll passage and a far-tongue region which is a region other than the near-tongue region, the plurality of nozzle vanes includes at least one near-tongue nozzle vane disposed in the near-tongue region and at least one far-tongue nozzle vane disposed in the far-tongue region. The at least one near-tongue nozzle vane has, in at least one of a leading edge or a trailing edge of the near-tongue nozzle vane, a notch that is cut out to a greater extent than a leading edge or a trailing edge of the far-tongue nozzle vane.
