Internal combustion engine operating method, involves adjusting lever element between turning positions for adjusting compression ratios of internal combustion engine, and supporting adjusting device at crank case of engine

摘要

The method involves mounting a lever element (16) at a crankshaft (12), and connecting the lever element with a connecting rod (18) and an adjusting device (24). The lever element is adjusted between two turning positions relative to a crank pin (14) by translatory movement of the adjusting device for adjusting two compression ratios of an internal combustion engine. The adjusting device is indirectly supported at a crank case of the internal combustion engine around a swiveling axis in a swivelable manner.
