4.12: Diesel Particulate Filter (DPF)
The diesel particulate filter requires high temperature exhaust gases to burn
off any soot that may accumulate there. If the exhaust gas temperatures do
not regularly reach the required level to burn off the soot it may lead to a
blockage. Reduced engine performance and increased fuel consumption may
result from a blockage.
In most cases it is possible to clear a blockage by working the engine hard
(e.g. driving the truck with a full load up an incline) for a period of at least 5
minutes so that the exhaust gases reach the temperature required to burn off
the soot. However in some cases the DPF may need to be removed and
cleaned.
Avoid prolonged periods of idling to prevent any blockages from occurring i.e.
switch off the engine when not in use.
Note
Where Diesel Particulate Filters (DPF) are fitted Diesel Fuels with a maximum
sulphur content of 15ppm (parts per million) MUST be used.
Diesel Fuels specified to EN 590 or ASTM D975 S15 are Strongly Recommended.
Note
If a diesel particulate filter (DPF) is fitted to the truck then API CJ-4 engine oil
MUST be used.
