Abstract
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 (7a) switches a DPF regenerating mode to a normal and acceleration coexistence regenerating mode (51) or an acceleration-sole regenerating mode (52), and DPF regenerating selection manipulation means (7b) switches a position to a normal regenerating permission position (53), a normal regenerating cancel position (54), or an acceleration regenerating execution position (55). When the DPF regenerating mode is in the acceleration-sole regenerating mode (52), 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 (7b).
