CRANKCASE VENTILATION SYSTEM COMPRISING A HEAT SHIELD

摘要

The invention relates to a fluid conduit for the internal combustion engine of a motor vehicle, in particular a crankcase ventilation conduit of an internal combustion piston engine. Said conduit comprises a first section (1), in which a fluid is conducted and to which a first wall (2), in particular an external wall, is allocated, a heat transfer from the ambient air to the fluid taking place via said wall. The conduit also comprises a casing (3), which essentially follows the contours of the first section (1) and surrounds said first section along one part of its periphery in such a way that an insulating air gap (4) is formed between the first wall (2) and the casing (3), shielding some sections of the first wall (2) from the passing ambient air. Said conduit can be used in motor vehicles, in particular passenger and commercial vehicles.
