Controlling of Heating Rates for Safe Regeneration of Ceramic Honeycomb Diesel Particulate Filter 880002

Thermal shock failures have been considered as one of the most significant issues for wall flow type ceramic diesel particulate filters during their regeneration.
This paper describes the experiments which were conducted in order to study effects of heating rates of the accumulated diesel particulate on the thermal shock failure of the filters using an NGK soot generator. The results showed favorable heating rates of the particulate in terms of the amounts of the accumulated particulate up to which the filters are safely regenerated.
