PM Thermal Regeneration - The Potential for Catalytic Combustion

An experimental study has been carried out to assess the capability of injecting vaporised fuel into the exhaust gas of a diesel engine to achieve elevated outlet temperatures from an oxidation catalyst for the thermal regeneration of particulate filters. Termed catalytic combustion and passive in nature, controlled experiments have proved the concept with the limitation on catalyst outlet temperature being dictated by the material limits of the exhaust system and the availability of oxygen.
