Automotive-air supply duct structure for use in motor vehicle, has auxiliary air filter channel that is branched-off from functional air channel to branching-out point, and extends from branching out-point to air filter

摘要

The automotive-air supply duct structure (10) has an air filter and a raw air-sided main air filter channel (20) guiding from an air filter-intake point (18) to the air filter. A functional air channel (24) is provided for temporally guiding the air from a functional air-intake point (22) to an air consumer. An auxiliary air filter channel (26) is branched-off from functional air channel to a branching-out point (28), and extends from branching out-point to air filter.
