ABSTRACT:
An internal combustion engine has an engine unit support, comprising such und-carrying parts as cylinders, cylinder head, pistons, piston rods, crankshaft bearings, and crankshaft, which is provided, at least at the output end thereof with a bracket of at least two arms which bracket is attached to the crankshaft bearing seats and is provided with at least one sound-insulating element on each end. At least some of the sound-insulating elements carry inner sleeves acting as setting elements whose axial position relative to outer sleeves thereof may be adjusted even after the engine unit support has been mounted in the crankcase. In this simple manner the sound-insulating elements may be provided with any desired pre-stressing, which will help to achieve optimum sound-insulation.
