Abstract
An apparatus V and a method, preferably for a motor vehicle, in particular a commercial vehicle. The apparatus V includes an internal combustion engine, an expansion machine and a generator. The expansion machine and the generator can be operatively connected both to one another and in each case to the internal combustion engine via a transmission, in order to make selective electrical utilization and mechanical utilization of the energy of the expansion machine possible.
Claims19
An apparatus, comprising:
- an internal combustion engine;
- an expansion machine;
- a generator,
- a transmission configured to operatively connect the expansion machine and the generator to one another and to the internal combustion engine via a transmission to make selective electrical utilization and mechanical utilization of energy of the expansion machine,
- wherein the generator is connected to a system, the system comprising:
- an energy store that can be charged by the generator for storing electrical energy;
- at least one electrical consumer of a motor vehicle;
- a DC/DC converter configured to supply the on-board power network of the motor vehicle, and
- a control device configured to controlling the generator.
An operating method for an apparatus, having an internal combustion engine, an expansion machine, a generator, a system to which the generator is connected, and a transmission, comprising:
- charging an energy store of the system by the generator for storing electrical energy;
- supplying by a DC/DC converter an on-board power network of the motor vehicle,
- controlling the generator by a control device;
- and one of:
- operatively connecting the expansion machine and the generator to one another and the internal combustion engine via the transmission, and
- operatively connecting at least one of the expansion machine and the generator to the internal combustion engine via the transmission, and
- selective utilization of electrical and mechanical energy of the expansion machine.
