1. An internal combustion engine comprising:
a crankcase;
a crankshaft rotatably mounted within the crankcase;
at least one connecting rod;
a crankshaft journal on which the at least one connecting rod is pivotably arranged;
a cylinder liner;
a piston is connected to the at least one connecting rod, the piston is configured and arranged to be displaced back and forth in the cylinder liner;
wherein the crankcase has an upper deck and a lower deck, each with one opening arranged to receive the cylinder liner, and in that the at least one connecting rod has an extent width which is greater than an outside diameter of the cylinder liner;
wherein at least the upper deck and the lower deck are configured and arranged for mounting the connecting rod, and wherein the upper deck has at least two clearances and the lower deck has at least two clearances, wherein each of the upper deck clearances and lower deck clearances are arranged symmetrically about a plane that extends along a longitudinal axis of the cylinder, and in that the resulting recess clears the at least one extent width of the at least one connecting rod and has a breadth which corresponds to the at least one width of the at least one connecting rod.
