Abstract
An internal combustion engine includes a cylinder block (2) defining a plurality of cylinders (5) reciprocably accommodating respective pistons (7), which are connected by respective connecting rods (9) to a common crankshaft (11), which is accommodated in a crankcase. Each cylinder communicates with a common inlet manifold (21) via one or more inlet valves (19). The crankcase communicates with the inlet manifold via a pathway which includes a droplet separator comprising a labyrinthine pathway. The crankshaft (11) carries a drive gear (13), which is in mesh with a plurality of driven gears (15) accommodated in a gearcase (6), which is connected on one end of the cylinder block (2), whereby the crankcase and the gearcase have adjacent opposed surfaces. The labyrinthine pathway is defined at least in part by the said opposed surfaces of the crankcase and the gearcase.
