Emissions Technology
Reliable
and
transparent
integrated
solutions
Cat NOx Reduction System
The
Cat
NOx
Reduction
System
captures
and
cools
a
small
quantity
of
exhaust
gas,
then
routes
it
into
the
combustion
chamber
where
it
drives
down
combustion
temperatures
and reduces
NOx
emissions.
Aftertreatment Technologies
Cat
aftertreatment
components
have
been
designed
to
match application
needs.
System
components
include
a
Diesel Oxidation
Catalyst
(DOC),
which
uses
a
chemical
process
to
convert
regulated
emissions
in
the
exhaust
system,
and
a
Diesel
Particulate
Filter
(DPF)
that
traps
and
removes
soot
until
burnt
off
through
regeneration.
The
DOC
and
DPF are
contained
in
the
Clean
Emissions
Module
(CEM)
that protects
the
components
and
simplifi
es
maintenance.
The CEM
will
control
if
regeneration
needs
to
occur
and soot level
is
monitored
through
the
display.
The aftertreatment
is
designed
to
remove
particulate
matter from
the
exhaust
without
the
need
for
operator
intervention
or
work
cycle
interruption.
Cat Low Temperature Regeneration System
The
low
temperature
Passive
Regeneration
system
works
transparently,
without
any
interaction
needed
from
the
operator.
Under
most
conditions,
engine
exhaust
will
remove
soot
through
passive
regeneration.
If
supplemental
regeneration
is
needed,
the
system
will
automatically
activate
the
exhaust
back
pressure
valve
to
supplement
regeneration.
This
will
result
in
burning
off
soot
in
the
DPF.
The
Cat
Low
Temperature
Passive
Regeneration
System
allows
fast
and
accurate
control
of
regeneration
independent
of
engine
exhaust
temperatures,
even
in
case
of
low
load
application
or
cold
ambient
temperatures.
Engine Idle Shutdown Timer
–
This
option
(when
activated
by the
operator)
shuts
down
the
engine
after
the
machine
has been
idling
for
a
pre-set
period
of
time.
Automatic Engine Speed Control (AESC)
–
It
reduces
engine
speed
when
the
machine
is
not
under
load
for
more
than
five seconds,
which
can
help
reduce
fuel
consumption
significantly
depending
on
the
application.
