<p><P>PROBLEM TO BE SOLVED: To highly maintain the maximum bed temperature of a filter regardless of a particulate regeneration amount during regeneration of a filter. <P>SOLUTION: This engine exhaust emission control device provided with the filter (41) collecting particulate in exhaust gas and regenerating the filter (41) at the time of regeneration of the filter (41), is provided with oxygen concentration increasing means (31, 24, 6, 42) increasing oxygen concentration in exhaust gas when increasing more the particulate regeneration amount being the combustion eliminating amount of the particulate deposited in the filter (41) during regeneration. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
