Diesel
Particulate

Regeneration
The
404F-E22
and
403F-E17T
families
of
engines
do
not
have
a
Diesel
Particulate
Filter
(DPF)
installed
within
the
aftertreatment
system.
The
404F-E22
and
403F-E17T
families
of
engines
use
a
different
technology
called,
the
Diesel
Oxidation
Catalyst
(DOC).
This
DOC
system
does
not
require
any
scheduled
maintenance,
and
will
not
be
included
in
the
Maintenance
Interval
Schedule.
In
order
for
the
404F-E22
and
403F-E17T
family
of
engines
to
meet
emissions
regulations
the
exhaust
gases
are
passed
through
the
DOC.
There
the
gases
react
with
the
catalyst.
The
aftertreatment
system
can
be
expected
to
function
properly
for
the
lifetime
of
the
engine
(emissions
durability
period).
However
for
the
aftertreatment
system
to
function
properly,
prescribed
maintenance
requirements
and
schedules
must
be
followed.
