Abstract
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.
