<p>PURPOSE:To carry out regenerating treatment accurately by detecting engine operating condition when particulates are collected. CONSTITUTION:An exhaust emission control device 1 for an internal combustion engine 51 is provided with the trapper 11 of particulates, a condition detecting means 21 for detecting collecting condition of the particulates, an operation detecting means 22 for detecting operating condition of the internal combustion engine 51, a temperature raising means 15 for carrying out combustion of the particulates, and a controller 40. In the controller 40, the temperature raising means 15 is operated on the basis of the operation hysteresis of the internal combustion engine 51 during collecting the particulates and present operating condition. The particulates may preferably be separately collected according to operating condition of the internal combustion engine 51.</p> |
