    摘要: In an internal combustion engine having a system for utilizing the waste heat from the internal combustion engine via the Clausius-Rankine cycle, a system includes a circuit having lines with a working medium, a working medium pump, a vaporizer-exhaust gas heat exchanger, and a vaporizer-EGR heat exchanger, an expander, and a condenser for liquefying the vaporous working medium. The line for the working medium is run from the condenser to the vaporizer-EGR heat exchanger so that the working medium, after flowing through the condenser, first flows through the vaporizer-EGR heat exchanger, and the line for the working medium is run from the vaporizer-EGR heat exchanger to the vaporizer-exhaust gas heat exchanger so that the working medium, after flowing through the vaporizer-EGR heat exchanger, first flows through the vaporizer-exhaust gas heat exchanger.

    摘要: The invention relates to a system for using the waste heat of an internal combustion engine by means of the Clausius-Rankine cycle, wherein an incorporation of an operating medium into the combustion air fed to the combustion engine due to lack of sealing or a leak at the evaporator heat exchanger is substantially ruled out. Said aim is achieved, according to the invention, in that the at least one first flow channel is formed by at least one first limiting component and the at least one second flow channel is formed by at least one second limiting component and there is a fluid-conducting connection to the surroundings or to a receiving chamber from the at least one first limiting component and preferably from the at least one second limiting component, so that in the event of a leak at the at least one first limiting component the operating medium can be conducted into the surroundings or into the receiving chamber and preferably in event of a leak at the at least one second limiting component the fluid can be conducted into the surroundings or into the receiving chamber.
