General information
The engine is a four-stroke, water-cooled die-
sel engine with direct injection.
The engine is equipped with a common rail
diesel injection system, cooled and regulated
exhaust gas recirculation and turbocharging
with charge-air pressure control.
Depending on the engine output, engine tur-
bocharging is either by means of single-stage
exhaust turbocharging or two stage exhaust
gas turbocharging with two sequential
exhaust gas turbochargers of differing dimen-
sions.
The valve gear has two camshafts at the top,
which are driven via a gearwheel drive.
The engine features a single-piece cylinder
head. In the cylinder head there are two inlet
valves and two exhaust valves per cylinder.
The valves are arranged symmetrically. The
symmetrical valve arrangement is optimal for
combustion.
The exhaust gas aftertreatment unit is char-
acterised by the following technologies:
R
selective catalytic reduction (SCR) with
ammonia slip catalytic converter
R
the diesel oxidation catalytic converter
(DOC)
The engine brake is a decompression brake. It
has a controlled exhaust valve which gives it
high braking power. The engine brake is con-
trollable in steps or modulated.
