Document Type and Number:
Japanese Patent JP6943808
Kind Code:
B2
Abstract:
There is provided an exhaust treatment device for a diesel engine that can prevent unnecessary alarm for ash deposition from being issued.In the exhaust treatment device, a timer measures integrated time IT of a state of non-regenerative operation which ranges from an end of DPF regeneration to a next time point where the differential pressure reaches a regeneration request value; a counter acquires the short interval count IC, if the integrated time IT is a short interval shorter than a predetermined decision time; and an alarm device issues an alarm, if the consecutive short interval count IC reached a predetermined plural necessary count for alarm. A short interval count IC having been already acquired is preferably reset to 0, if the integrated time IT of the state of non-regenerative operation is a long interval not shorter than a predetermined decision time, before the short interval count IC reaches a predetermined necessary count for alarm.
