Abstract: An oil catching system for an internal-combustion engine, particularly for an opposed cylinder engine, has an oil catching housing arranged below a crankcase. An oil suction space is provided in the oil catching housing from which the lubricating oil is transported by way of a main oil pump equipped with an oil suction pipe to consuming devices. At least one oil collecting space adjoins the oil suction space, in which oil collecting space the lubricating oil coming from the consuming devices is returned by way of an oil pipe. The oil suction space is separated from the oil collecting space by at least one oil separating wall, in which at least one passage opening is arranged which can be controlled by way of a flap, by way of which passage opening the lubricating oil can flow from the oil collecting space into the oil suction space.

Abstract: The invention relates to a crankcase for an internal-combustion engine, particularly for a horizontally opposed engine, having two crankcase halves (10, 12) in which bearing sections (18) with bearing bores (24) for the crank pins of a crankshaft are arranged, the two crankcase halves (10, 12) being screwed to one another in the area of the bearing bores (24), as well as having cylinder bores (14, 16) for receiving the pistons. It is suggested that the plane of division (30) of the two crankcase halves (10, 12) extend at an angle &agr;, and that the longitudinal axis (36) of the bearing bolts (26, 28) extend essentially at a right angle with respect to the plane of division (30). This results in a screwing-together of the two crankcase halves (10, 12) which is free of transverse force and is arranged close to the bearing bore (24).
