<p><P>PROBLEM TO BE SOLVED: To provide an exhaust emission control device of an engine capable of preventing various evils by post-injection of a large quantity, by promoting a temperature rise in a filter after reducing a post-injection quantity, when forcibly regenerating the filter in idle operation. <P>SOLUTION: When forcibly regenerating the filter 38 in the idle operation, an air compressor 58 is continuously operated for supplying compressed air to an air tank 60. An intake heater 13 for raising the temperature of intake air, a compressor 56 of an air conditioner and a cooling fan 53 of a radiator 54 are operated, and the temperature rise in the filter is promoted by raising the exhaust temperature by an increase in an engine load. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
