Abstract
The invention relates to an oil collecting arrangement for an internal-combustion engine having an oil collecting housing (2) arranged below a crankcase, which oil collecting housing (2) has at least two sections of different space depths, in a deeper space section (4), an oil scavenging line (8) being provided by means of which the lubricating oil is delivered to the consuming devices by way of a pump. It is suggested that, in the oil collecting housing (2), a separate insertion part (18) is fastened which, on the one hand, has an oil barrier (22, 28) aligned transversely to the longitudinal dimension of the oil collecting housing (4) (2), which oil barrier (22, 28) prevents a flowing back of the lubricating oil from the deeper space section (4) into the crank space and/or into the flatter space section (12) in the inclined position of the internal-combustion engine, and which, on the other hand, has oil return ducts (34, 38, 40) for the lubricating oil flowing back from the cylinder head.
