Abstract
An arrangement for converting thermal energy from lost heat of an internal combustion engine into mechanical energy where a working circuit is provided for a working medium which can be heated and evaporated using the lost heat. An expansion machine for obtaining mechanical energy from the heat of the working medium is provided in the working circuit where the working circuit extends through a heat exchanger mounted upstream of the expansion engine in the flow direction of the working medium. The internal combustion engine includes a cylinder having a cylinder liner. A cooling duct is provided in the cylinder liner through which the working medium flows. The cylinder liner is formed by centrifugal casting where the cooling duct is introduced into one centrifugal mold as an insert prior to the centrifugal casting.
