Abstract

Official abstract text for this publication.

A turbocharged internal combustion engine disclosed that may comprise an engine block with a first end side opposing a second end side and a two-stage turbocharged system. The two-stage turbocharged system may comprise a low-pressure turbocharger with a first turbine and a first compressor and a high-pressure turbocharger with a second turbine and a second compressor. A turbine connection may fluidly connect the first turbine and the second turbine and a compressor connection fluidly connects the first compressor and the second compressor. The low-pressure turbocharger is mounted at the first end side of the engine block and the high-pressure turbocharger is mounted at a second end side of the engine block.
