A variable geometry turbine (VGT) for turbochargers incorporates a turbine nozzle having a plurality of vanes, each vane having an airfoil with an inner disc and an outer disc. A first nozzle plate incorporates pockets to receive the inner discs with the inner discs substantially flush with a nozzle surface on the first nozzle plate. A second nozzle plate has pockets to receive the outer discs with outer discs substantially flush with a second nozzle surface. An integral actuation system rotates the plurality of vanes for variation of the nozzle geometry.

Balanced vanes and integrated actuation system for a variable geometry turbocharger

A variable geometry turbine for turbochargers in exhaust gas recirculation engines incorporates a turbine housing having an exhaust inlet with a first side receiving exhaust from cylinders having exhaust gas recirculation (EGR) and a second side receiving exhaust from non-EGR cylinders. The first side has a first EGR-driving passage and a second EGR-driving passage and the second side having a first non-EGR-driving passage and a second non-EGR-driving passage. A first control valve is associated with the second EGR-driving passage and a second control valve is associated with the second non-EGR-driving passage. A controller is adapted to control the first and second control valves.
