ABSTRACT:
A gear train housing of an engine of the type having an internal gear space located within housing parts which include at least one housing body part and at least one cover part. In accordance with a preferred embodiment, the lower end of the gear space is substantially embodiment, the lower end of the gear space is substantially of a V-shape defined laterally on opposite sides by a radially facing sloping walls of the housing body part. In order to minimize oil related problems, bosses on the upwardly facing sloping walls have a wedge-like shape with a downwardly inclined, inwardly facing surface and are free of upwardly sloping surface portions which can collect fluid flowing over the bosses in proximity to a gasket seal between edge faces of the housing parts, and a splash shield is formed for preventing excessive quantities of oil from being splashed, by a crankshaft gear, into the area of other gears of the gear train, so as to reduce associated frictional losses.
