An internal combustion engine has evaporative cooling and waste heat utilization in a common vapor circulation system. The internal combustion engine includes a first exhaust gas heat exchanger. An evaporator system fluidly connected to the first exhaust gas heat exchanger is formed from a cooling jacket heat exchanger inside a housing for the evaporative cooling. A second exhaust gas heat exchanger is fluidly connected to the evaporator system. An expansion machine is fluidly connected to the second exhaust heat exchanger. A condenser is fluidly connected to the expansion machine. A feed pump is fluidly connected to the condenser. A third exhaust gas heat exchanger is disposed in an exhaust gas train. The first exhaust gas heat exchanger is fluidically connected to the second exhaust gas heat exchanger via the third exhaust gas heat exchanger and then via the cooling jacket heat exchanger.

Internal combustion engine with evaporative cooling and waste heat utilization

A charging device for internal combustion engines includes a compressor part configured to compress drawn-in combustion air. The compressor part is arranged in an intake line of the internal combustion engine and is connected to the internal combustion engine via an actuatable mechanical coupler. An expansion part is disposed in a circulation system for a circulating working medium. The circulation system includes at least one exhaust-gas heat exchanger and a circulation pump such that the expansion part is driven utilizing waste heat from the internal combustion engine. An electric machine is connected to the expansion part so as to drive the compressor part. The electric machine is connected to the compressor part. An operational electric connection is disposed between the electric machine and a battery so that electric energy is stored during an energy-recovery mode or else so that electric energy is provided to drive the electric machine.
