Abstract:
A turbocharger with at least one axial turbine stage. Separate circumferential sections of the turbine are fed by separate exhaust system runners. The turbine is designed to harness pulse energy. Corresponding engine having cylinders comprising such a turbocharger.

Claim (Index 9):
An engine having cylinders and a pulse-driven exhaust-gas-driven turbocharger, and including:\n a turbine housing in which an axial turbine wheel is housed in a cylindrical turbine wheel space having an inlet side and an outlet side, the turbine wheel having an axis of rotation, the turbine housing designed to direct exhaust gasses through the turbine wheel in a generally axial direction, runners ( 10 a,  10 b,  10 c ) separately supplying exhaust gas from one or more cylinders of the engine to different circumferentially separated sectors of the turbine wheel space of the turbocharger, the sectors collectively feeding the entire axial inlet side of the turbine wheel space, wherein each of the runners introduces exhaust gas from the engine into the turbine housing perpendicular to the axis of rotation of the turbine wheel, and more radial than tangential, wherein, in a radial-to-axial flow transition section, each of the runners or a back wall of the turbine housing is shaped to transition exhaust gas flow from an inlet direction of flow that is more radial than tangential, to a substantially axial flow, wherein guide vanes are positioned in the transition section, the guide vanes shaped to impart a swirl component to the exhaust gas flow, wherein at least some of the guide vanes are positioned at the junctions of runners, to maintain pressure pulse separation by substantially isolating exhaust flow of adjacent runners up to the turbine wheel.
