Abstract

PURPOSE: To automatically repeat capturing and self-purification of fine particles by movably fitting one of two filter media arranged in the exhaust gas filter and passing current through a heater to burn the fine particles in the contact of the two filter media with each other in Diesel engine.
CONSTITUTION: The first filter medium 24 is fixed and the second filter medium 26 is movably provided in the exhaust gas filter. The filter media are provided with electrode layers 30, 32 and heated by means of the heater 36 through which currents are passed in the contact thereof. When fine particles are accumulated in the filter media and cause loadings, the second filter medium 26 is displaced upwards to touch with the electrodes 30, 32 and the heater 36 is operated. The fine particles are burnt by the heater 36. Thus, since the fine particles are automatically repeatedly captured and self-purified, the filter function can suitably be maintained over a long period in running.
