Abstract

In a reciprocating piston internal combustion engine to be installed horizontally in a motor vehicle the cylinder block (2), the cylinder head (4), one half (8) of the crankcase and the oil sump (9) are formed from a single casting, the oil sump being positioned below the cylinder block and having an opening (13) in the same plane as a flat surface (12) on the cylinder head which locates a camshaft case (14). The camshaft case (14) and the oil sump cover (17) are formed as one unit, and a stay between the camshaft case and the oil sump cover accommodates the drive shaft (21) of an oil pump (22) located in the oil sump and driven by the camshaft. A second stay (19) between the camshaft case and the oil sump cover contains a duct (25) for conveying oil from the camshaft case back into the oil sump.
