Reciprocating piston for a reciprocating piston engine and reciprocating piston engine, and cylinder of a reciprocating piston engine

A reciprocating piston machine, comprising:

• a reciprocating piston consisting essentially of a ceramic material;
• a crank mechanism, in particular a Scotch yoke mechanism, in which the piston is rigidly connected to a piston rod by a cap screw, and in which at least one disc composed of a metallic material is clamped between the reciprocating piston and the piston rod;
• wherein the screw comprises a metallic material;
• a thermal expansion coefficient αpiston of the material of the reciprocating piston is lower than a thermal expansion coefficient αscrew of the material of the screw and the at least one disc is an expansion compensation disc;
• a thermal expansion coefficient αdisc1;2 of the material of the expansion compensation disc is greater than the thermal expansion coefficient αscrew of the material of the screw;
• and
• wherein a difference between a clamping force of the cap screw at room temperature and a clamping force at a rated operating temperature of the reciprocating piston machine, which the reciprocating piston machine assumes during extended operation at a rated speed, is <0.
