Summary:

Application of ceramic honeycomb wall-flow type diesel particulate filters (DPF) to heavy duty vehicles requires a large volume filter. Heavy duty vehicles produce a large volume exhaust gas, and pressure drop in the exhaust system must be maintained to a certain level. In addition, the filters must be designed to resist fracture from thermal stresses during regeneration. This is particularly important in heavy duty vehicles because of these extended mileage requirements.These studies of the effects of DPF volume on thermal shock resistance during regeneration reveal that the maximum failure temperatures are lower as DPF volume is increased, still maintaining 950°C maximum temperature with 12 ℓ volume and 9D 12L size large DPF.Some thermal stress analyses with temperature profiles and finite element analysis were conducted on four different volume DPF during regeneration
