Abstract:
A cartridge for use in a pulse energy enhanced turbine of a turbocharger. At least first and second fixed separating blades ( 12 ) are provided between a nozzle ring ( 6 ) and a disk ( 29 ), the separating blades ( 12 ) maintaining separation of exhaust gas flows through a guide grid between a divided volute and a turbine wheel ( 11 ). Exhaust pulsation energy from different cylinders or cylinder groups of an engine or engine bank are kept separated up to the turbine wheel, so that the turbine wheel reacts to individual pulses of exhaust gas flow from engine exhaust ports

Claim (Index 1):
A turbocharger turbine comprising:\n a turbine housing ( 2 ) housing a turbine wheel ( 11 ), said turbine wheel rotatable about an axis of rotation (R), said housing ( 2 ) including a divided volute adapted for receiving divided exhaust gas flows from an engine and maintaining separation of exhaust gas flows from different cylinders or cylinder groups of the engine; and a variable turbine geometry cartridge mounted in said turbine housing and comprising: a plurality of guide vanes ( 7 ) arranged in said housing ( 2 ) downstream of said divided volute, in angular separation around said axis of rotation (R) in an axially extending vane space, each vane ( 7 ) being pivotal about an associated pivot axis ( 8 ), forming nozzles of variable cross-section between adjacent vanes ( 7 ); a generally annular nozzle ring ( 6 ) for supporting said vanes ( 7 ) for pivoting about their respective said pivot axis ( 8 ), said nozzle ring ( 6 ) forming a first axial limitation of said vane space; a disk ( 29 ) with a central opening, said disk connected to and spaced from said nozzle ring ( 6 ) at a predetermined axial distance to form a second axial limitation of said vane space, and at least a first and a second fixed separating blade ( 12 ) provided between said nozzle ring ( 6 ) and said disk ( 29 ) for continuing separation of exhaust gas flows from said divided volute to said turbine wheel ( 11 ) or to at least one of said guide vanes ( 7 ).
