Abstract
A ceramic exhaust trap regenerator provides a push-pull heat channeling method of transferring heat to and through the ceramic monolith with a flow of super-heated air. The application of heat is controlled by pulling the hot air through the monolith and away from the downstream side of the monolith through a vacuum hose. The regeneration process is started and completely controlled by an off-board mobile regeneration console with the engine off. The console is a wheeled cart with attachments that include an air heater, vacuum and positive pressure air pumps with attaching hoses, a temperature-actuated relay, a particulate filter, process timers, a heat exchanger, a cooling fan, and an electrical controller.
Claims17
An apparatus for regenerating a filter trap used to collect particles from the exhaust gas of an internal combustion engine, comprising:
- an outer casing containing a filter trap centrally located therein, said casing having entrance and exit ports, the entrance port connected to and receiving exhaust gas from an exhaust pipe of an internal combustion engine and the exit port connected to and discharging filtered exhaust gas into a tailpipe;
- means for providing a flow of super-heated air to a point just upstream of the filter trap to ignite particulates contained therein;
- and
- a vacuum pump connected to said casing just downstream of said filter trap to assist the flow of said super-heated air through the filter trap and to draw off said exhaust gas.
