Title:

EXHAUST TREATMENT DEVICE OF DIESEL ENGINE

Document Type and Number:

Japanese Patent JP2018003624

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide an exhaust treatment device of a diesel engine capable of suppressing problems that DPF cannot be regenerated due to interruption of automatic regeneration processing.SOLUTION: An exhaust treatment device of a diesel engine includes a parking regeneration request notification component and a parking regeneration starting operation component. Regeneration processing S2, S11 of DFP is composed of automatic regeneration processing S2 and parting regeneration processing S11, the automatic regeneration processing S2 is automatically started on the basis that a PM accumulation amount estimation value F of DFP reaches a prescribed automatic regeneration starting determination value SJ, and the parking regeneration processing S11 is executed when following first condition and second condition are satisfied. The first condition is that notification S8 of the parking regeneration request is performed by the parking regeneration request notification component on the basis that the number of times of interruption N of the automatic regeneration processing S2 reaches a prescribed parking regeneration request determination value NS or more, and the second condition is that the parking regeneration starting operation component starts the operation in a state that an engine-mounting machine does not run and work.SELECTED DRAWING: Figure 2
