ARRANGEMENT FOR PREVENTING BEARING-RELATED NOISE IN INTERNAL COMBUSTION ENGINES

摘要

Internal combustion engine with variable compression, comprising a crankshaft-bearing crankcase part (2) and a cylinder-receiving part (6) arranged tiltably thereon by means of a tilt axle bearing (8) on one side of the engine and a tilt mechanism (10) on the other, opposite side of the engine, which cylinder-receiving part (6) supports a cylinder head (14) which is securely connected thereto, preferably with camshafts mounted therein. Arranged between the crankcase part (2) and the cylinder-receiving part (6) there are prestressing members (38) which force these engine parts apart and work to counteract the occurrence of bearing play in the tilt axle bearing (8) and in the tilt mechanism (10) when compression-modifying tilting movement between the cylinder-receiving part (6) and the crankcase part (2) occurs during running of the engine.
