ABSTRACT:
An improved vehicle exhaust handling system capable of accomodating vehicles of varying sizes while maintaining optimal exhaust capabilities is disclosed. A motor vehicle with its engine operating is positioned in a test center in a predetermined location. A chamber is located in the floor of the test center below the rearward portion of the vehicle. A plurality of hinged shutters and a grate behind the shutters are disposed over the chamber. An exhaust fan creates an airflow from the test center into the chamber and to an outside location. The shutters are individually controllable, and a mechanism is provided to close off a flow of air through the grate whenever any of the shutters is opened. Depending on the size of the vehicle and the position of its tailpipe, an individually selected shutter is opened or all the shutters are closed and the exhaust gases are directed into the grate. Portable deflectors are provided for positioning adjacent to the tailpipe of the vehicle. The deflectors further enhance the exhaust capabilities of the system.
