PARTICULATE MATTER REDUCING APPARATUS FOR DIESEL ENGINE

摘要

Disclosed is a particulate matter reducing apparatus for a diesel engine capable of reducing particulate matter in a convenient manner through a relatively compact structure, preventing the shortening of the lifespan of a filter, and improving particulate matter burning efficiency. The particulate matter reducing apparatus for a diesel engine according to the present invention includes a housing arranged on a flow channel for the passage of exhaust gas from the diesel engine, a filter accommodated in the housing to collect particulate matter from the exhaust gas flowing into the housing, electrodes for transmitting electrical signals to the filter, and a control unit for controlling electrical signals from the electrodes. The particulate matter reducing apparatus of the present invention is advantageous in that particulate matter is burned and removed by directly heating the filter. The apparatus of the present invention is more convenient than the system wherein a filter needs to be removed and washed. Further, the apparatus of the present invention is structurally compact and has a lower manufacturing cost than a system wherein a filter is heated by an electrical heater or a diesel burner. Further, the apparatus of the present invention is advantageous in that the filter is relatively uniformly heated rather than being partially heated, lengthening the lifespan of the filter.
