A Filter Tube Trap System for Light Truck Applications 920139
An electrically regenerated trap system has been developed based on the use of multiple filter tubes. The design individually isolates a filter tube during regeneration through the use of a newly developed poppet valve. The regeneration process is quickly completed by integrating the heaters and filter tubes together. The need for external combustion air has been eliminated. Also, the trap replaces the function of the muffler. The controller uses a simple algorithm basing regeneration need on easily measured parameters. The trap system operates on 12 volts. A system was installed on a pickup truck for field test purposes. Data collected from the onboard logging system, including electrical system impact and trap performance are reviewed.
