Electric Heating Regeneration of Large Wall-Flow Type DPF 910136
Ceramic wall-flow type diesel particulate filters (DPF) are being investigated for the aftertreatment systems of heavy duty engines. To use ceramic DPF more reliably and easily, electric heating regenerations are studied varying combustion air flow rates and amounts of accumulated soot.
Despite electric heater capacity limitations, it is possible to regenerate DPF at a certain combustion air flow rate without thermal shock failure. The maximum withstood temperature against thermal shock failure of electric heating regeneration is similar to that of diesel burner regeneration on DPF with a nine inch diameter and a twelve inch length.
