Apparatus for increasing regenerative filter heating element temperature |
摘要 |
A filter device for trapping particulates for diesel engine exhaust gases includes an electrical heating element to heat the face of the ceramic filter. A porous ceramic disc is place on the side of the heating element opposite the filter. It has been found that the disc keeps the temperature of the heating element more uniform and reduces the time to particulate ignition on the front face of the filter.
