Thermodynamic engine
First Claim
1. Thermodynamic engine which converts thermal energy of a superheated vapor into kinetic energy in a decompression device, comprising:
- a low-temperature circuit in which a first working medium is transported by a first pump through a first heat exchanger and subsequently through the decompression device, and a high-temperature circuit in which a second working medium is transported by a second pump through a second heat exchanger and subsequently through the decompression device, the first heat exchanger and the second heat exchanger being provided on an exhaust gas system of an internal combustion engine, wherein the internal combustion engine has a coolant circuit which regulates the temperature of the first working medium in a first collection container, the low-temperature circuit has an injection device which injects first working medium withdrawn from the low-temperature circuit back into the low-temperature circuit in the vicinity of the first heat exchanger, and the high-temperature circuit between the second heat exchanger and the decompression device has a heating device for the second working medium.

Abstract
A thermodynamic engine converts the superheated steam of at least one working medium into kinetic energy using a decompression device. Said engine includes a low-temperature circuit, in which a first working medium is transported through a first heat exchanger and subsequently through the decompression device and a high-temperature circuit, in which a second working medium is transported through a second heat exchanger and subsequently through the decompression device. The first heat exchanger and the second heat exchanger are located in the exhaust system of an internal combustion engine, and the internal combustion engine a coolant circuit can be used to heat the working mediums in separate collection containers.
