Piston pin for internal combustion engines, system of piston pin and piston, engine with piston pin or system of piston pin and piston and use of a piston pin or a system of piston pin and piston for engines

摘要

The present invention is directed to a piston pin for internal combustion engines, which consists of a case hardened steel and is characterized in that a ratio of a residual wall thickness of the piston pin to a total thickness of a case hardening layer is 2, and a ratio of inner diameter and outer diameter of the piston pin 60 % is. Furthermore, the present invention is directed to a system of the piston pin according to the invention and a piston, wherein the piston has a piston hub with a transverse ovality, which corresponds to an ovalization of the piston pin under maximum ignition pressure. The invention also includes an engine, in particular internal combustion engine, with the piston pin or the system of piston pin and piston and a use thereof for engines, in particular internal combustion engines.
