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.
A reciprocating piston internal combustion engine, including a cylinder head, a cylinder block providing the cylinder bores, a crankcase, an oil sump, and a camshaft case, and including a main casting which constitutes said cylinder head and cylinder block and also forms part of said crankcase and part of said oil sump, and including a second casting which forms said camshaft case together with a cover for said oil sump, and in which said cylinder head is formed with a locating surface for said camshaft case, and said oil sump has an opening for said oil sump cover lying in the same plane as the locating surface on said cylinder head.
