摘要：<p>PROBLEM TO BE SOLVED: To provide a diesel exhausted fine particle control device provided with a heating means capable of effectively activating a catalytic converter arranged on the front stage by low electric power even in the operating condition of a diesel engine, in which the exhaust gas temperature is low and also a catalyst is not activated. SOLUTION: In a diesel exhausted fine particle control device, a plurality of band-shaped heaters 1a, 1b composed of heater heat generating layers having the specified width are provided next to the upstream side of a catalytic converter 2, and partial heating-type heaters so arranged that the distance between respective band-shaped heaters 1a, 1b may have the same width are provided. Therefore, when a filter 3 is regenerated in the operating condition in which the exhaust gas temperature is low and a catalyst 2 is not activated, the partial heating-type heaters electrically generate heat and partially activate the catalytic converter 2, and therefore, the catalytic converter 2 can be effectively activated by low electric power.</p>
