Abstract (en)
[origin: EP2273093A1] The piston (3) has a piston head fixed in a segmented and/or slotted manner with an enlarged contact surface with respect to a working piston (7) between the piston and a working medium i.e. air. Thermal energy is emitted from the piston to the working medium. The working piston and the piston are mechanically coupled with each other. A set of longitudinal slots is formed in the piston head, where through-flow of the working medium is achieved through the piston head out of a region of a heat exchanger in a direction of a piston pin. An independent claim is also included for a thermal engine provided with a driven flywheel or a crankshaft having a closed total interior to be filled with a working medium and closed in a pressure-tight manner, comprising a heat exchanger connected with a working chamber and a heat transmission chamber.
