Abstract

An internal combustion engine includes a crankcase with a crankshaft which drives at one end face of the crankcase, auxiliary aggregates--oil pump--and endless elements. The oil pump and the endless elements are covered off by means of a covering which consists of a sheet metal part including two thin-walled layers and is constructed pot-shaped in cross section. This light-weight covering which is simple in construction is secured at the end wall of the crankcase by means of an edge flange and by means of bolts.
