Abstract
An internal combustion engine includes a crankcase in which a crankshaft is held. An oil guide housing is positioned beneath the crankcase, and an oil pump with a drive sprocket for supplying lubricating oil is positioned in the crankcase. The oil pump supplies lubricating oil to consumers from an oil trap in the oil guide housing. The sprocket is encompassed by a cover, and resources are provided in the sprocket cover for scraping/separating lubricating oil that has been drawn along out of the oil trap in the direction of the crankcase by a chain that drives the sprocket. In this manner, the lubricating oil that is drawn and/or carried along by the drive chain is prevented from entering the crankcase and/or the cylinder head of the internal combustion engine.
