Engine Diesel Particulate Filter (DPF)
General information about DPF
The loader is equipped with a Diesel Particulate
Filter (DPF). This filter removes fine particles that are
produced during burning of Diesel fuel. The filter is
not visible, it is located inside the exhaust system of
the loader.
As the DPF collects the particles, they will remain in
the filter and slowly they will disturb the flow of
exhaust gas. To overcome this the soot collected in
the DPF is cleaned by burning the soot. This burn
process (regeneration) is automatic and does not
normally require action from the operator of the
loader.
In normal use of the loader the control systems of the
loader automatically take care of the DPF and there
is no need to use manual controls of the DPF.
To ensure that the automatic DPF regeneration is
possible, operate the loader so that the engine
reaches its normal operating temperature, and
ensure the engine is loaded. Avoid idling with the
loader as it promotes accumulation of soot and ash.
WARNING
Risk of fire and burns - Hot
exhaust gas.
Pay attention to the
hot exhaust gas symbol on the
display. When it is lit, the exhaust
gas is especially hot. Wait until
DPF regeneration is completed. Do
not drive or park near combustible
materials. The automatic and
manually activated DPF
regeneration process produce hot
exhaust gas.
.
DPF Regeneration
Regeneration method of the DPF depends on
accumulated soot load. In normal use the
regeneration process starts automatically. Some
users may never need to do any of the manual
processes.
Do not drive near combustible materials or dust, and
do not park the rear of the loader near any structure
or other vehicle. The exhaust temperature is hot
during active regeneration.
Inside the DPF there is a coating that makes it
possible to burn the soot during normal use, when
the exhaust temperature is hot enough.
Ash load
After each regeneration process a small amount of
ash accumulates in the filter. Eventually the ash load
becomes too high and the DPF must be serviced.
This will typically require thousands of operating
hours. However, frequent idling of the engine, poor
or wrong quality of engine oil, or operating the loader
so that the engine will rarely reach its operating
temperature, can cause ash to accumulate into the
DPF. Ash load can be seen from the display. If ash
load is high, contact Avant service.
