monoxide. The system consists of a catalyst and AdBlue®/DEF-
injection.
The system is monitored and controlled by the aftertreatment
control module (ACM).
The exhaust system is certified as spark arrester according to
Directive 97/68/EC and EN 1834.
D11E
The engine is only valid for Brazil, LAM, and China markets.
D11F
The engine applies to other markets where the M-engine and E-
engine markets mentioned do not apply.
AdBlue®/DEF information
AdBlue®/DEF is needed to reduce nitrogen oxides (NOx).
AdBlue®/DEF is filled in a separate tank on the machine which is
completely separated from the fuel tank. AdBlue®/DEF may not
be mixed in the fuel tank, and fuel may not be mixed in the
AdBlue®/DEF-tank.

market):

For information on ordering AdBlue®/DEF (other markets),
contact an authorized dealer.

Exhaust aftertreatment system
Engines without diesel particulate filter (DPF)
The engine features an exhaust aftertreatment system (EATS)
that consists of a muffler that contains a selective catalytic
reduction system (SCR) which reduces the emissions content of
nitrogen oxide (NO
x
) from the exhaust gases.
EATS uses fluid for diesel exhaust gases, known as AdBlue® or
DEF, to reduce NO
x
emissions. AdBlue®/DEF is injected into the
exhaust muffler, where it reacts in the SCR.
The AdBlue®/DEF tank is fitted with sensors for quality, level and
temperature. The quality sensor is used to assess the correct
quality and concentration of AdBlue®/DEF. It registers whether
anything other than AdBlue®/DEF is added to the tank.
In order to ensure reduction of NO
x
emissions, EATS is monitored
by the aftertreatment control module (ACM).
