<p><P>PROBLEM TO BE SOLVED: To provide, at low cost, an exhaust emission control device of an internal combustion engine capable of reducing the total exhausted amount of emission by reducing the exhausted amount of the emission before a catalyst is activated. <P>SOLUTION: This exhaust emission control device comprises a catalyst poisoning detection means detecting the poisoning state of the catalyst (step S12) and a catalyst heating means increasing the heating speed of the catalyst by increasing a time for raising an exhaust temperature after the start of the engine (step S15). <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
