Abstract
Advanced techniques for regenerating diesel particulate traps are described. A bypassable trap system minimized regeneration thermal energy requirements. Thermal regeneration systems with burners or electric resistance heaters were evaluated. Regeneration emissions and fuel consumption penalties were measured. Catalytic fuel additives consisting of octoate based compounds of copper and nickel, and copper and cerium provided reductions of up to 410°F in trap regeneration temperature. Durability tests confirmed frequent self regeneration with fuel additives. Over 95% of the fuel additive was collected by the trap. The useful life of the trap having a volume equal to engine displacement was estimated to be 30,000 miles.
