Abstract
An internal combustion engine comprises an engine unit support which contains the engine parts directly affected by body resonance (cylinderhead, cylinder, piston, connecting rod, crankshaft main bearing, and crankshaft) and a crankcase connected to the engine unit support by flanges located above the crankshaft. The crankshaft main bearings consist of bearing blocks and bearing caps which are connectable to main bearing units independently from the main bearing bolts. The bearing units are detachably secured to the engine unit support. The crankcase is provided with at least one aperture closed by at least one cover part below the crankshaft, said apertures providing access to the main bearing bolts. Dismounting of the engine unit support is enabled with the crankshaft and the main bearing units mounted thereon remaining in the crankcase and the crankcase remaining mounted on its place, for instance in a vehicle.
