2. DPF REGENERATION AND DPF CLEANING

As mentioned above, the filter is a device to capture fine particles.
The filter is clogged with the increase of the engine operating time.
When this occurs, the filter is "regenerated" by burning and removing soot.
However, since ash cannot be removed by the regeneration of the filter, there is a need for "cleaning" of the filter
by removing ash at regular intervals by a cleaning contractor using specialized equipment.
1. DPF Regeneration
Said engine has the DPF regeneration mode described below (function to burn and remove deposited soot).
(a) Automatic regeneration
(b) Parked regeneration
Manual regeneration with a diagnosis
(c)
tool (Diagmaster)
2. Cleaning of ash based on maintenance intervals
Since ash deposited in the filter cannot be removed by regeneration, periodical cleaning is required.
There is a need to clean the filter at the pre-determined maintenance intervals (3,000 hours) by a cleaning
contractor using the specialized equipment by removing the DPF filter comp from the DPF muffler full assy.
3. Cleaning of heavy soot and ash accumulation on filter
a) In the case of cleaning request due to heavy soot accumulation
b) In the case of cleaning request due to increase the frequency of regeneration
In this case, there is a need to clean the filter by a cleaning contractor using the specialized equipment by
removing the DPF filter comp from the DPF muffler full assy.
Regeneration by automatic control is performed using post injection.
The operation of the product can be continued.
If regeneration cannot be carried out depending on the situation of the work, the operation of
the installed product is stopped to carry out regeneration.
Such regeneration is performed as urgent measures in the event of abnormal soot deposition.
