<p><P>PROBLEM TO BE SOLVED: To provide a fuel adding device for post-treatment capable of reducing the accumulated amount of soot in piping and suppressing the consumption of compressed air. <P>SOLUTION: The fuel adding device for post-treatment includes a fuel injection mechanism 4 for post-treatment and a control device. The fuel injection mechanism 4 for post-treatment includes air supply systems La, Va, 41, fuel supply systems Lf, Vf1, Vf2, 42, and an internal pressure measuring device 43. The control device 10 has a function of controlling the internal pressure to be not lower than the pressure of an internal combustion engine exhaust system in the case of not forcibly regenerating a filter for catching noxious particulate components in exhaust gas flowing through the exhaust system based on the measured result of a measuring device for measuring the pressure of the internal combustion engine exhaust system and the measured result of the internal pressure measuring device 43. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
