4.10.3 SCR technology and AdBlue product

In Hyundai vehicles, a gas reduction system based in SCR technology (Selective Cat-
alytic Reduction) is usedin order to comply with legislation on exhaust. This tech-
nology requires the use of a product called AUS 32 (also known as AdBlue), which
contains a 32.5 % urea solution.
This system consists of the following main components:
-
-
-
-
-
The AdBlue product contained in the tank, (usually heated), is injected through a
dosing module in the exhaust pipe at the height of the collector, through a pipe driv-
ing. Once the AdBlue product is injected into the SCR system, this triggers a chemical
reaction in the catalytic converter, which converts the NO
gen and water vapour, both natural substances to the environment.
The product AdBlue has a limited life. When the product has to be changed
because it no longer has the appropriate properties, and it is replaced by a new
product, the AdBlue tank should be filled properly, and the old product disposed
of in compliance with laws and regulations of each country.
