Abstract
An internal combustion engine is equipped with a turbocharger that includes: a centrifugal compressor impeller; an axial flow turbine wheel coupled to the compressor impeller via a rotational shaft; a bearing that supports the rotational shaft; and a housing that houses at least the compressor impeller and the bearing among the compressor impeller, the bearing and the turbine wheel. The turbine wheel is coupled to the rotational shaft such that an outlet of turbine blades of the turbine wheel is located on the side of the compressor impeller. The compressor impeller is arranged such that an inlet of the compressor impeller becomes closer to the turbine wheel than an outlet of the compressor impeller.
Claims3
A turbocharged internal combustion engine system comprising:
- an internal combustion engine;
- and
- a turbocharger including:
- a single centrifugal compressor impeller including a single inlet and an outlet;
- an axial flow turbine wheel coupled to the centrifugal compressor impeller via a rotational shaft, the inlet of the centrifugal compressor impeller being closer to the axial flow turbine wheel than the outlet of the centrifugal compressor impeller such that the centrifugal compressor impeller is configured to create a pressure differential that results in a force directed towards the axial flow turbine wheel, the axial flow turbine wheel being coupled to the rotational shaft such that an outlet of a plurality of turbine blades of the axial flow turbine wheel is disposed on a side facing the centrifugal compressor impeller;
- a bearing that supports the rotational shaft;
- and
- a housing that houses the single centrifugal compressor impeller, the bearing, and the axial flow turbine wheel.
