摘要

The engine has a piston (2) and a piston pin (3) that is supported with its ends on the piston, so that the piston is connected with a connecting rod (4). The piston pin has a modifiable axial length in a non-installed position. The ends of the piston pin are supported in the recesses of the piston.
