A reciprocating internal combustion engine comprises an engine block, which includes cylinders, cylinder heads, pistons, connecting rods, a crankshaft and the mainshaft bearings for the crankshaft. That engine block is held in an outer pan by means of annular supporting elements, which are provided at both ends of the engine block and are coaxial to the crankshaft and insulate against a transmission of structure-borne noise. The engine block is sealed to the upper edge portion of the outer pan only by an oil seal. The outer pan consists of two parts, which are connected by screws. To prolong the service life of the annular supporting elements and to reduce the manufacturing costs, the outer pan has a parting plane which contains the axis of the crankshaft. The supporting elements are secured in the outer pan merely by being clamped between the two parts of the pan.
