Abstract
A two-stage turbocharger assembly for an internal combustion engine is provided. The assembly has a single low pressure turbocharger, and more than two high pressure turbochargers arranged in parallel with each other. The compressor outlet of the single low pressure turbocharger is operatively connected to the compressor inlets of the high pressure turbochargers. The turbine outlets of the high pressure turbochargers are operatively connected to the turbine inlet of the single low pressure turbocharger.
Claims18
A two-stage turbocharger assembly for an internal combustion engine, the assembly having:
- a single low pressure turbocharger, and
- a plurality of high pressure turbochargers arranged in parallel with each other, a compressor outlet of the low pressure turbocharger being operatively connected to compressor inlets of the high pressure turbochargers, and turbine outlets of the high pressure turbochargers being operatively connected to a turbine inlet of the low pressure turbocharger;
- wherein the assembly has more than two of the high pressure turbochargers.
14 The two-stage turbocharger assembly of claim 13 wherein each high pressure turbocharger is adapted to send compressed air to and receive exhaust gas from one or more respective combustion chambers of the internal combustion engine, the high pressure turbochargers being arranged in the assembly so that each high pressure turbocharger is adjacent the respective chamber when mounted at the cylinder head, and the high pressure turbochargers being divided into two or more groups, the high pressure turbochargers of each group not serving the combustion cylinders of the other group.
The two-stage turbocharger assembly of claim 14 wherein each group includes one or more of the high pressure turbochargers.
