Abstract:
1. A common family internal combustion engine, comprising: an engine block assembly having a substantially horizontally disposed lower end defining a lower end interface closed by an oil pan and an angled upper end defining an angled upper end interface extending at an angle α relative to the lower end interface from a rear of the engine block assembly to a front thereof, the angled upper end interface and the lower end interface intersecting at said rear of the engine block assembly; an engine block mated to the engine block assembly at the angled upper end interface and thereby closing the angled upper end of the engine block assembly such that the engine block assembly and the oil pan and the engine block together define a crankcase that is configured to house a crankshaft for rotation about a crankshaft axis, the crankshaft further comprising three crankshaft journals supported by journal bearings for rotation about the crankshaft axis, the crankshaft axis being disposed at the angled upper end of the engine block assembly; first and second piston pins and associated first and second piston/rod assemblies disposed in piston cylinders of a first cylinder housing assembly; and a cylinder head configured to close open ends of the piston cylinders to thereby define combustion chambers with the first and second piston/rod assemblies, the first cylinder housing assembly reclined from vertical, towards the rear of the engine block, about the crankshaft axis by an angle β relative to vertical.
