Abstract
The present disclosure relates to an arrangement of auxiliary assemblies in a combustion machine including an electric machine which is operable as a generator and preferably also as a motor. The arrangement further includes an expansion machine, in particular an expansion machine of a waste heat recovery system for converting waste heat of the combustion machine or of an engine braking system into utilizable energy by way of a steam circuit, and a first group of auxiliary assemblies, including a water pump, a fuel predelivery pump, a high-pressure fuel pump, a steering assistance pump and an oil pump.
Claims21
An arrangement of auxiliary assemblies in a combustion machine, comprising:
- first electric machine which is operable as a generator;
- an expansion machine;
- wherein the first electric machine and the expansion machine are operatively connected by way of a gear drive to a crankshaft of the combustion machine;
- and
- an arrangement of auxiliary assemblies, having a water pump, a fuel pre-delivery pump, a high-pressure fuel pump, a steering assistance pump and an oil pump;
- wherein the arrangement of auxiliary assemblies is implemented without a belt drive;
- and
- wherein the water pump, the fuel pre-delivery pump, and the steering assistance pump are electrically driven with the electric power coming from the first electric machine or an on board electrical system;
- and
- wherein the high-pressure fuel pump and the oil pump are mechanically driven by the gear drive operatively connected to the combustion machine.
