<p><P>PROBLEM TO BE SOLVED: To provide an exhaust emission control device in which a carrier for catalyst is heated uniformly, whereby capable of raising the temperature of the catalyst borne by the carrier to the activation temperature even when the engine is going to make a cold start. <P>SOLUTION: The exhaust emission control device 100 is arranged so that the carrier 20 in cylindrical shape is heated electrically through electrodes 30 and 40 to raise the temperature of the catalyst borne by the carrier 20 to the activation temperature, the carrier 20 being formed in honeycomb structure with a plurality of bulkheads 21, 21... through which the current for heating the carrier 20 flows between the electrodes 30 and 40, wherein the thickness of the bulkheads 21, 21... is set so that the electric resistances of all current paths between terminals 50 and 60 are the same. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
