Abstract

An internal combustion engine has at least one piston which performs stroke movements in a cylinder crankcase. Via two connecting rods, the piston interacts with two parallel crankshafts which rotate synchronously in opposite directions. The connecting rods have, on a side facing toward a piston crown of the piston, bearing eyelets which, via piston pins, are operatively connected to the first and second bearings provided at opposite first and second sides of the piston, which bearings and piston pins act as a device for compensating an asymmetry of the profile of the crankshafts. To optimize the internal combustion engine, the first and the second bearings have cylindrical bearing disks which, firstly, are rotatably mounted in piston bores and which, secondly, include disk bores for receiving first and second pin sections of the piston pins.
