Abstract
There is provided an arrangement of an internal combustion engine with a sequentially parallel twin turbocharger, in which at least one turbocharger has an electrical energy converter which can be used optionally as a motor for driving a compressor in the lower rotational speed range of the internal combustion engine or as a generator for charging a connected battery.
Claims20
A system, comprising:
- a turbocharged engine with a first turbocharger comprising at least a first turbine and a first compressor, and a second turbocharger comprising at least a second turbine and a second compressor, where the first and second turbochargers are arranged in parallel;
- an exhaust line comprising a valve device located between the engine and the second turbine;
- and
- a first electrical energy converter located on a second shaft between the second turbine and the second compressor.

A method, comprising:
- operating at least a first electrical energy converter coupled to a second turbocharger shaft in a generator mode while operating and a second electrical energy converter coupled to a first turbocharger shaft in a motor mode, responsive to an exhaust flow amount and a battery state of charge.
A system, comprising:
- a twin turbocharged engine;
- a first turbocharger parallel and sequential to a second turbocharger, where the first turbocharger comprises a first turbine and a first compressor on a first shaft, and where the second turbocharger comprises a second turbine and a second compressor on a second shaft;
- an exhaust gas transverse line located between the engine and the second turbine, wherein exhaust gas flows directly to the second turbine via the exhaust gas transverse line when a valve device is in an open position;
- a first electrical energy converter located on the second shaft between the second turbine and the second compressor;
- a second electrical energy converter located on the first shaft between the first turbine and the first compressor;
- and
- a battery electrically coupled to the first electrical energy converter and the second electrical energy converter.
