Embodiment Construction
[0027] figure 1 A perspective view of a region of an internal combustion engine 1 is shown, which is present, for example, as a serial internal combustion engine, in particular a four-stroke four-cylinder serial internal combustion engine. Internal combustion engine 1 has a crankshaft 2 and a plurality of pistons 3 (here: four pistons 3 ), wherein each piston is movably mounted in one of the plurality of cylinders of internal combustion engine 1 . Each of the pistons 3 is connected to the crankshaft 2 via a piston connecting rod 4 . The crankshaft 2 is rotatably mounted in bearings, also not shown, of a cylinder crankcase (not shown here) of the internal combustion engine 1 and has, for example, a plurality of central journals 5 for bearing and a plurality of pin journals 6 (of which only one can be seen in each case in the figures), their longitudinal center axes are offset in different angular orientations parallel to the axis of rotation 7 of the crankshaft 2 .
