A statorless or nozzleless axial turbine for a turbo-supercharger includes an axial turbine wheel which accommodates the eddy current of exhaust gas in an axial direction. The turbine includes a sector-divided turbine housing which has multiple extra exhaust gas inlets for accommodating an extra exhaust gas stream separately from an internal combustion engine. The sector-divided turbine housing further includes a sector passage having multiple extra angles which occupy each part of the circumference surrounding the turbine wheel. The sector passages having each angle are formed consecutively with each other in a circumferential direction. The sector passages having each angle receive the exhaust gas from one of the exhaust gas inlets. A turbine housing assembly includes an extra sector outlet for the sector passages having each angle. The turbine housing assembly may include a separately formed heat shroud, and the sector outlet can be at least partially formed by the heat shroud. |
