Petrol Particle Filter - Volvo V60 2018 Owner's Manual

Petrol particle filter

Petrol cars are fitted with particle filters for more
efficient emission control.
Particles in the exhaust gases are collected in
the petrol particle filter during normal driving. In
normal driving conditions, passive regeneration
takes place, which leads to the particles being
oxidised and burned away. The filter is emptied in
this way.
If the car is driven at low speed or with repeated
cold starts in low outside temperature, active
regeneration may be necessary. Regeneration of
the particulate filter is automatic and normally
takes 10-20 minutes. There may be a smell of
burning during regeneration.
Use the parking heater in cold weather - the
engine then reaches normal operating tempera-
ture more quickly.
When driving short distances at low
speeds in a petrol car
The capacity of the petrol 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 petrol
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.

STARTING AND DRIVING
Diesel
Diesel is a type of engine fuel that is intended for
cars with a diesel engine.
Only use diesel fuel from well-known producers.
Never use fuel of dubious quality. Diesel fuel
must fulfil the EN 590 or SS 155435 standard.
Diesel engines are sensitive to contaminants in
the fuel, such as excessively high volumes of sul-
phur and metals.
At low temperatures (lower than 0 °C (32 °F)) a
paraffin precipitate may form in the diesel fuel,
which may lead to starting problems. The fuel
qualities that are sold must be adapted for sea-
son and climate zone, but for extreme weather
conditions, old fuel or moving between climate
zones, paraffin precipitate may occur.
The risk of condensation in the fuel tank is
reduced if the tank is kept well filled.
When refuelling, check that the area around the
fuel filler pipe is clean. Avoid spilling fuel onto the
paintwork. Wash off any spillage with detergent
and water.
