Air filter system for industrial engine of motor car, has housing part forming sub-segment of peripheral channel wall circumferentially with respect to air flow where direction of installation of channel insert is transverse to air flow

摘要

The system has a sensor function unit (40) arranged with a sensor channel insert (48) and an air mass flow sensor (52). An air duct section (22) of two housing parts (12, 14) is assembled with the sensor channel insert between the housing parts. The sensor conduit insert is inserted in an interior (36) of the air duct section by the housing parts. Each housing part forms a sub-segment of a peripheral channel wall circumferentially with respect to air flow (24), where the direction of installation of the sensor channel insert is transverse to the air flow.
