<p><P>PROBLEM TO BE SOLVED: To provide an exhaust gas aftertreatment device in which fuel is not wasted, and a regeneration method thereof. <P>SOLUTION: A communicating pipe 61 is connected to individual exhaust pipes 11, 12, at an exhaust upstream side of a disposed position of a filter 20. The exhaust pipes 11, 12 are communicated with each other via the communicating pipe 61. HC dosing devices 40, 40 for supplying hydrocarbon (HC) into the exhaust pipes 11, 12 for purpose of regeneration of the filter 20 are provided, at exhaust upstream side of the disposed position of the filter 20, and at exhaust downstream side of a connection position of the communicating pipe 61, for each of the exhaust pipes 11, and 12. On at least either one exhaust pipe, for instance, on the exhaust pipe 11, a sensor 30 is provided to detect a regeneration time of the filter 20. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
