A reciprocating internal combustion engine comprises an engine block, which includes the cylinders, cylinder heads, pistons, connecting rods, a crankshaft and main bearings for the crankshaft. The engine block is oiltightly mounted in an outer pan and is held in said outer pan by supporting elements which are provided at both end faces of the engine block and insulate against a transmission of structure-borne sound. The engine block is sealed at the top edge portion of the outer pan only by an oil seal. The supporting elements are coaxial to the crankshaft. To minimize the transmission of vibration to the supporting elements which insulate against the transmission of structure-borne sound, said supporting elements are connected to the engine block by holders, which extend below the cylinders and are secured to the engine block approximately in the middle of the region traversed by the piston heads between their top and bottom dead center positions.
