Abstract

Internal combustion engine (1) has oil-conveying device (4) which is an exhaust pump for a bearing house (50) of a exhaust-gas turbocharger (5) or a compressor of the internal-combustion engine. The oil recycle piping (3) is attached to the bearing house or under bypass of the bearing house on a suction side of the exhaust pump.
