ABSTRACT:
An internal combustion engine includes an oil collector housing positioned beneath a crankcase housing. A lubricating oil pump is positioned inside the oil collector housing, and the oil collector housing contains at least one oil-collecting chamber, into which an oil suction line leads from the lubricating oil pump, forcing the lubricating oil through the delivery side to consumers. A system for supplying lubricating oil to the drive shaft of at least one turbocharger is mounted on the internal combustion engine. The lubricating oil that is fed to the turbocharger is returned via oil lines to the oil-collecting chamber of the internal combustion engine. At least one ascending channel is integrated into the oil collector housing, via which the lubricating oil that has been suctioned off from the turbochargers is returned above the oil level in the oil collecting chamber. Lubricating oil being returned from the turbocharger will be returned above the oil level in the oil trap of the internal combustion engine, even when the vehicle is traveling downhill.
