Diesel Particulate Filter - Volvo XC90 Owner's Manual

Points to remember when filling with a
fuel can
When filling diesel with a fuel can, use the funnel
located under the floor hatch in the cargo area.
Make sure you insert the funnel's pipe firmly into
the filler pipe. The filler pipe has two opening
caps. The funnel's pipe must be pushed past
both caps before filling can be started.

Diesel particulate filter

Diesel cars are fitted with particle filters for more
efficient emission control.
Particles in the exhaust gases are collected in
the diesel particle filter during normal driving.
When these conditions have been met, regenera-
tion starts to burn off the particles and empty the
filter. To start regeneration, the engine must have
reached normal operating temperature. Regener-
ation of the particulate filter is automatic and nor-
mally takes 10-20 minutes.
NOTE
The following may arise during regeneration:
•
a smaller reduction of engine power may
be noticed temporarily
•
fuel consumption may increase temporar-
ily
•
a smell of burning may arise.
Use the parking heater* in cold weather - the
engine then reaches normal operating tempera-
ture more quickly.
IMPORTANT
If the filter is completely filled with particles, it
may be difficult to start the engine and the fil-
ter is non-functional. Then there is a risk that
the filter will need to be replaced.
STARTING AND DRIVING
When driving short distances at low
speeds in a diesel car
The capacity of the diesel emission control sys-
tem is affected by how the car is driven. It is
important to drive varying distances at different
speeds to achieve optimal performance.
Driving short distances at low speeds (or in cold
climates) frequently, where the engine does not
reach normal operating temperature, can lead to
problems that can eventually cause a malfunction
and trigger a warning message. If the vehicle is
mostly driven in city traffic, it is important to regu-
larly drive at higher speeds to allow the diesel
emission control system to regenerate.
•
The car should be driven on A-roads at
speeds in excess of 60 km/h (38 mph) for at
least 20 minutes between each refuelling.
