<p><P>PROBLEM TO BE SOLVED: To provide an exhaust emission purifying apparatus for an internal-combustion engine capable of performing more suitably regeneration of an exhaust emission purifying member provided in an exhaust passage. <P>SOLUTION: A DPF 26 for collecting soot in exhaust emissions is provided in an exhaust passage 14 of an internal combustion engine 10. When a deposition amount of soot at the DPF 26 exceeds a predetermined amount, fuel addition to the DPF 26 is performed. When an addition amount is set at the time of the fuel addition, an electronic control device 50 calculates a correction amount with respect to a basic addition amount. As the correction amount, a correction amount based on deposition amount of soot and an intake air temperature and a correction amount based on the deposition amount of soot and atmospheric pressure are calculated. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
