1.1.2 Exhaust Gas Treatment System (ATS)

Note
The following texts are excerpts from the operating instruc-
tions of the engine manufacturer.
(VM engine Euro 6)
The ATS system consists of a catalytic converter "Diesel
Oxidation Catalyst (DOC) ", a particle filter"Diesel Particu-
late Filter (DPF) "and a catalytic converter"Selective Cata-
lyst Reduction (SCR) ". These components burn the
collected particles as part of a "regeneration process" and
reduce the nitrogen oxides (NOx). Effective regeneration
requires that the exhaust gases escape at a high temper-
ature over a period of time. The exhaust gases must have
a suitable temperature for regeneration, otherwise the
DPF will continuously filter and thereby incurs a risk of be-
coming clogged. An actively regenerated post-treatment
system is used to avoid clogging of the filter.
The exhaust gases of a diesel engine contain nitrogen ox-
ides (NOx), which must be reduced. In accordance with
pollutant emission standards, the current post-treatment
system has been integrated with an "SCR" system.
The system for reducing the NOx gases consists of a dos-
ing control unit (DCU Box), a tank for the reaction fluid DEF
(Diesel Exhaust Fluid), a DEF injector and a catalytic con-
verter SCR.
The liquid "Diesel Exhaust Fluid "(DEF) or known as Ad-
Blue® as a trade name is pumped through the dosing con-
trol unit (DCU box) into the injector. The injector atomizes
the liquid in front of the SCR catalytic converter, causing a
chemical reaction. This chemical reaction converts the ni-
trogen oxides (NOx) contained in the exhaust gases into
water vapour and nitrogen.
AdBlue® or DEF is a non-toxic, colourless, odourless and
non-flammable liquid. It is poured into a special container
in the vehicle and injected into the exhaust system to clean
the exhaust gases.
