SiC Diesel Particulate Filter Application to Electric Heater System 1999-01-0464

A heater type automatic regeneration system able to be mounted on an automobile has been developed by utilizing the characteristics of SiC-DPF (Diesel Particulate Filters made of Silicon Carbide). In this development, in order to apply the system to wide applications, the main objective was to focus on reducing the regenerating electric power consumption. For the reduction of the power consumption, realization of a low pressure drop system effect by making the DPF structure high density and improvement of the axial insulation, controlling the gas flow velocity by a general purpose exhaust brake, saving of the electric power by using a DC heater driver utilizing MOSFETs (Metal Oxide semi-conductor field-effect transistor). As a result, a SiC-DPF heater unit usable in wide range of applications has successfully been developed.
