EXHAUST EMISSION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an exhaust emission control device which realizes arbitrarily forced regeneration of a particulate filter by the will of a driver. SOLUTION: An exhaust emission control device equipped with a catalyst regeneration type particulate filter 6 in the middle of an exhaust pipe 4 with the exhaust gas 3 distributed therein comprises forced-regenerating means (a control device 12 and a fuel injector 13) to regenerate the particulate filter 6 by forcibly burning and removing the particulate trapped by the particulate filter 6, and an operating means (a regeneration button 17) provided on a driver' s seat so as to arbitrarily operate the forced-regenerating means.
