A nd AdB L u E® AddItIVE
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 15 litres.
It has an exterior filler located behind the
fuel filler flap below the fuel filler cap and
closed with a blue filler cap.
The objective of BlueHDi is to reduce by
up to 90% the emissions of NOx (nitrous
oxides) in the air, 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
®
fluid into the exhaust system. This operation can also be carried out
by a CITROËN dealer or a qualified
workshop.
Scr technology
Filling of the AdBlue® tank can be done
using:
-

5 or 10 litres containers equipped with a

10 centimetre filler tube or the filling kit
available from CITROËN dealers,
-

1.89 litre botles that are screwed onto

the filler neck, available from CITROËN
dealers,
-

or when at a fuel filling station equipped

with a special AdBlue
® delivery pump for
heavy or light vehicles.
