An active Diesel Particulate Filter (DPF) regeneration technology has been developed in which diesel fuel is oxidized in the presence of a proprietary catalyst system, regenerating the DPF in an efficient and controlled manner. Several important benefits for such a system include light off at low exhaust temperatures, which allows active regeneration over a wide range of vehicle uses, the ability to heat the DPF uniformly without hot spots or uncontrolled temperature extremes, lower backpressures and fuel penalty costs and a control strategy that could be substantially independent of the engine management system. The Xonon Fuel Combustor (XFC™) provides for active regeneration of the DPF at various vehicle loads and speeds. System attributes include activation at engine exhaust temperatures as low as 220°C and an outlet temperature that can be efficiently controlled over a wide range, as high as 700°C.
