ABSTRACT:
In a heavy-duty truck having a turbocharged internal combustion engine and a lubricating system wherein lubricating oil from the engine oil reservoir is circulated both within the engine and also to and from an associated brake system air compressor, supercharged air is passed to the oil crankcase of the air compressor to cause lubricating oil to drain therefrom and return to the engine oil reservoir. This minimizes windage and resulting engine power losses, reduces oil consumption and avoids problems associated with the undesired entry of lubricating oil into the brake system via the air compressor.
