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

Exhaust treatment device for a diesel engine

An object of the present invention is to provide the exhaust treatment device of a diesel engine which is capable of prohibiting the execution of DPF regenerating processing in a situation in which the DPF regenerating processing is inappropriate. In order to achieve the object, DPF regenerating mode switch manipulation means () switches a DPF regenerating mode to a normal and acceleration coexistence regenerating mode () or an acceleration-sole regenerating mode (), and DPF regenerating selection manipulation means () switches a position to a normal regenerating permission position (), a normal regenerating cancel position (), or an acceleration regenerating execution position (). When the DPF regenerating mode is in the acceleration-sole regenerating mode (), the DPF regenerating control means prohibits normal regenerating processing by the DPF regenerating means irrespective of a position selected by the DPF regenerating selection manipulation means ().
