Abstract
The DPF temperature distribution which has a great effect on regenerating the ceramic filter effectively was measured at 30 locations using K-type thermocouples. Five partitioned electric heaters were used for heating the ceramic filter and they are switched ON/OFF in order. Also, the temperature distribution in the ceramic filter was measured with varying the electrical power supply to the heaters and the mass flow rate of the air supply from a blower. The uniform distribution of the air flow velocity at the inlet of the DPF make that of the temperature in the ceramic filter. The difference in heating ability between the partitioned heaters had a great effect on the temperature distribution in the ceramic filter.
