Abstract
The disclosed exhaust treatment device for a diesel engine can prevent heat damage to a DPF when regenerating said DPF. If a selection device (7), which selects whether to allow or prohibit an automatic DPF regeneration process, is set to prohibit the automatic DPF regeneration process, a DPF regeneration control device (4) is made able to start a process to cancel execution of the automatic DPF regeneration process. If the selection device (7) is set to allow the automatic DPF regeneration process, the DPF regeneration control device (4) retracts the cancellation of the automatic DPF regeneration process, allowing execution of the previously-cancelled automatic DPF regeneration process to begin.
