<p><P>PROBLEM TO BE SOLVED: To provide an exhaust emission control device, surely making an occupant recognize a manual regeneration timing of a filter to prevent clogging of the filter. <P>SOLUTION: This exhaust emission control device of an engine includes: a DPF 65 for scavenging fine particles discharged from an engine 1; a manual regeneration means 93 for regenerating the DPF 65 by increasing the engine rotating speed to a predetermined rotating speed at least to regenerate the DPF 65; and a warning lamp 55 giving a warning to make a driver operate a manual regeneration switch 50 when the quantity of fine particles scavenged by the DPF65 is equal to or larger than a first thresholdβ, wherein when the quantity of fine particles scavenged by the DPF 65 is equal to or larger than a second thresholdδabove a first thresholdβ, the quantity reduction control for reducing the maximum fuel injection quantity is performed by an injection control means 90. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
