テイキユレートトラツプフイルタ再生装置。 A particulate trap filter is disposed in the exhaust passage, and the heating part of the filter regeneration device for burning and removing the collected particulate is disposed upstream of the particulate trap filter, and the particulate trap filter is disposed in the center of the inside of the filter. and a second temperature detection means that detects the temperature of the downstream corner inside the filter. Based on this, the amount of heating by the filter regeneration device is reduced when the temperature at the center inside the filter exceeds a predetermined value, and the amount of heating by the filter regeneration device is increased when the temperature at the center falls below the predetermined temperature. 1. A particulate trap filter regeneration device, comprising: a control means for stopping the operation of the filter regeneration device when a corner temperature inside the filter reaches a predetermined temperature or higher.
