SHB WL34 * 2.0 1-73
Maintenance 1
Exhaust gas treatment
Regeneration of diesel particulate filter
Description
The soot resulting from the combustion of the diesel fuel is collected and
burned in the diesel particulate filter DPF at regular intervals. The exhaust
gas reaches a temperature of up to 600°C (1112°F) at the exhaust outlet
during this process. This process is called regeneration.
The soot load is the contamination level in the diesel particulate filter.
Among other things, this contamination level depends on the load on the
diesel engine:
- High engine load = less deposits.
- Low engine load = more deposits.
Damage to the diesel particulate filter!
If the soot load of the diesel particulate filter reaches a critical value, the
diesel particulate filter/engine can be damaged.
Engine output is reduced if the soot load reaches a critical value.
► If engine output is reduced, immediately start manual regeneration in a
safe environment – see "Manual regeneration" on page 1-77.
► Wait until manual regeneration is finished.
A running regeneration stops if the engine runs at idling speed and electric
consumers are switched on.
► During regeneration at idling speed, switch off all electric consumers
on the machine.
