Abstract
An air cleaner for a motor vehicle. The air cleaner includes a housing having side walls and a bottom wail defining a chamber. A filter is received within the chamber and cooperates with the housing to define a collection chamber. A primary inlet defines a primary passage into the collection chamber, and a secondary inlet defines a passage bypassing the collection chamber. The secondary inlet also includes a conduit, having an end abutting the filter. The air cleaner further includes a door positioned with respect to the secondary inlet so as to generally obstruct the secondary inlet when the door is in a closed position. The door is pivotable about weakened regions to an open position if the airflow through the primary passage is lower than a critical level.
