BLUEHDI AND ADBLUE®
SCR technology
AdBlue® is the brand name of the
solution needed for operation of the
SCR system. BlueHDi vehicles have a specific
AdBlue
® additive tank with a capacity
of 17 litres.
It has an exterior filler with a blue filler
cap, located to the left of the Diesel
fuel filler cap.
Filling of the AdBlue
® tank can be
done using 5 or 10 litre containers,
1.89 litre bottles, or when at a fuel
filling station equipped with a special
AdBlue
® delivery pump for light
vehicles.
The aim of BlueHDi is to reduce the
emissions of NOx (nitrous oxides) in
the air by up to 90%, using a system
that converts NOx into water vapour
and nitrogen in a dedicated catalytic
converter: SCR (Selective Catalytic
Reduction).
This objective meets the "Euro 6"
emissions standard adopted by the
European Union aimed at limiting the
emissions of pollutants from internal
combustion engines.
The SCR technology used on BlueHDi
engines involves the injection of
AdBlue
® into the exhaust system.
This operation can also be carried
out by a CITROËN dealer or a
qualified workshop.
Please note that the high delivery
pumps at some filling stations,
intended only for lorries and coaches,
are not suitable for cars or light
commercial vehicles.
Never use these pumps.
