Controlling the
Regeneration Process
Introduction
Your vehicle is equipped with a
two-position Regeneration Start
Switch, located in the roof console.
The DPF system consists of a
Hydrocarbon (HC) Doser (may not
apply to all engines), a Diesel Oxidation
Catalyst (DOC), and a DPF. The DPF
filters soot out of the exhaust. When
activated, the HC Doser sprays a small
amount of diesel fuel (the HC) into
the exhaust. The catalyst in the DOC
reacts with the HC to generate heat.
The heat is used to clean (regenerate)
the DPF by reducing the trapped soot
to ash.

The driver can initiate a Parked
Regeneration when certain
operating conditions are suitable
for regeneration. Refer to Parked
Regeneration on page 3-12.
Y53–1190–1C1
WARNING!
If you operate in environments that
contain explosive vapors or flammable
materials, notice that your vehicle is
equipped with a Regeneration Stop
Switch with a STOP function. The
STOP function must be activated prior
to entering the above environment(s)
to prevent automatic engine regeneration from occurring, which could cause
an explosion or fire. Failing to activate
the STOP function before entering a
combustible environment may cause
an explosion or fire that could lead to
death, personal injury, equipment or
property damage.

Functionality / Notification
Information
to the warning lamps and indicator
symbols of the ATS.
The ATS will regenerate the DPF by
using hot exhaust gases normally
generated by the engine. Typically
occurring during highway operation,
this referred to as a "Passive"
Regeneration and is transparent to the
operation of the vehicle.
The ATS may not be able to regenerate
the DPF when the vehicle is driven at
extended low speeds or with frequent
starts and stops. In such cases,
warning lamps and indicator symbols
will alert the operator to take action.
The operator should be aware of
whether the lamps are on alone or in
combination with others. The following
table will describe each warning
lamp(s) and what actions are needed
from the operator.
Occasionally, the exhaust gases
are not hot enough for passive
regeneration. When this occurs,
the ATS will regenerate the DPF by
increasing the exhaust temperature.
This is referred to as an "Automatic"
Regeneration and is also transparent
to vehicle operation. An Automatic
Regeneration event typically lasts 30
minutes. During and shortly after the
event, the exhaust gases from the DPF
may reach temperatures in excess of
650°C (1200°F). See the information in
the following table on probable causes
and recommended actions related

WARNING!
Temperature of the tail pipe, exhaust pipe, diesel particular filter (DPF), selective catalytic reduction (SCR) device and surrounding components including enclosures and steps, will be elevated during and shortly after a regeneration event or normal
vehicle operation when engine is under high or heavy loading. If the High Exhaust System Temperature (HEST) warning
lamp is on:
•
Do not park in an area of combustible vapors or materials. You must keep combustibles at least 1.5 m (5 ft) away from the exhaust (outlet)
stream (as it exits the tail pipe) while the HEST lamp is illuminated. Always park your vehicle outside. Failure to do so could ignite an
explosion or harm bystanders which could result in serious injury.
•
Do not park in an area where people are close by. You must keep combustibles at least 1.5 m (5 ft) away from the exhaust outlet while the
HEST lamp is illuminated. Failure to do so could result in serious injury.
•
Temperature of the tail pipe, exhaust pipes, diesel particular filter (DPF), selective catalytic reduction (SCR) device and surrounding
components including enclosures and steps becomes elevated during engine operation or any regeneration event and can cause serious
burns to the skin. Allow adequate cooling time before approaching, working on or near any part of the exhaust system or surrounding

DPF Regeneration
Carefully read the following instructions
to regenerate the DPF. If you have any
problems or difficulties contact your
nearest authorized PACCAR dealer for
assistance.
3
The ATS requires conditions typically
found in highway driving to regenerate
the DPF. If the DPF warning lamp is
illuminated, the easiest option is to
assist the ATS by proceeding to the
nearest highway.
•
Make sure the Regeneration
STOP Switch is NOT in the STOP
position.
•
Select a highway that has a posted
legal speed of more than 64 kph
(40 mph).
•
Drive your vehicle until the DPF
lamp goes off. This may take 30 45 minutes of speeds greater than
64 kph (40 mph) for a PACCAR
engine.
If your operation or planned route in
the immediate future limits your ability
to reach highway speeds, proceed
to the next section titled Parked
Regeneration.
3-12
Y53–1190–1C1
Parked Regeneration
In very limited applications or
operations the DPF must be
regenerated by initiating a Parked
Regeneration. Follow these seven
steps to initiate a Parked Regeneration:
1.
Pull the vehicle over to a safe
location.
2.
Ensure no one is in the immediate
vicinity to the tail pipe.
3.
Maintain a minimum of 5 feet
of clearance to any combustible
materials from the edge and top
of the vehicle.
(12/10/2013)
Diesel Particulate Filter (DPF) System
WARNING!
WARNING!
NOTE
Never initiate a regeneration in a
closed building or enclosure. Always
park your vehicle outside and ensure
no one is in the immediate vicinity.
Failure to comply could ignite a fire or
cause an explosion, resulting in death,
personal injury, equipment or property
damage.
Parking the vehicle too close to any
combustible materials or vapors may
start a fire, ignite an explosion or burn
someone standing close by. Before
pushing the Regeneration START
switch on the dash, walk around your
vehicle and ensure you have at least
five (5) feet clearance from the sides
and top of your vehicle to any combustibles. Ensure no one is in the
immediate vicinity to the tail pipe. Failure to comply could ignite a fire or
cause an explosion, resulting in death,
personal injury, equipment or property
damage.
Typical operation areas or materials
that can contain explosive vapors,
flammable materials or people in close
proximity of the vehicle are:
•
Fuel depots
•
Grain elevators
•
Dry grass, leaves or trees
•
Transfer refuse stations/dumps
•
Parking lots
•
Load/unload terminals

Idling in Freezing
Temperatures
3
Idling the engine for 3 or more hours
in freezing temperatures causes the
buildup of soot and moisture in the
DPF. Extra heat is required to oxidize
the soot and moisture by using the
following methods:
•
DPF Regeneration:
If the DPF Lamp turns on follow
the instructions described under
DPF Regeneration on page 3-12.
NOTE
•
PACCAR PX-7 Engine:
Regardless if the DPF lamp is
on or off, the engine speed will
automatically increase to 1000
to 1100 RPM and remain at this
speed for 10 minutes to perform
an automated DPF cleaning.
If necessary, the RPMs can
be lowered by depressing the
throttle, clutch, or brake pedal.
If the engine continues to idle,
the aftertreatment system will try
again to raise the idle speed until
the aftertreatment temperatures
are suitable.
If you ignore the warning lamp and do
not initiate regeneration at the soonest, safest possible time, the DPF will
become increasingly clogged with soot
and can lead to engine shutdown.

During normal operation of the truck,
the DEF tank straps may relax. Inspect
the spring on top of the strap. If more
than ½ in. (12.7 mm) of the spring
is exposed, the bolt will need to be
re-torqued between 70 – 80 in-lbs. (7.9
– 9 Nm). This distance is measured
from the washer at the end of the
spring to the edge of the tube at the
top of the straps.

Tampering with
Aftertreatment System
The aftertreatment system for your
vehicle as installed from the factory
was specifically designed to meet the
emissions requirements of the US
Environmental Protection Agency and
California Air Resources Board. Any
changes of component locations or
modifications of any aftertreatment
system components may reduce the
emission effectiveness and you may
be subject to fines under the United
States Clean Air Act.

Diesel Particulate Filter (DPF) System
Diesel Particulate Filter
(DPF) System
•
Overview
The DPF system consists of a
Hydrocarbon (HC) Doser (may
not apply to all engines), a Diesel
Oxidation Catalyst (DOC), and a DPF.
•
Soot is composed of the partially
burned particles of fuel that occur
during normal engine operation
(black smoke).
•
Over time, both soot and ash
accumulate in the DPF and must
be removed. Soot is removed by
a process called regeneration.
Ash is removed by removing the
DPF and cleaning it at specified
intervals.
The components of the DPF system
perform the following functions:
•
•
•
The ATS inlet and outlet adapt
the vehicle exhaust piping to the
ATS, and also provide a mounting
location for the aftertreatment gas
temperature sensors.
The DPF differential pressure
sensor measures the restriction
across the DPF.
The DPF filters soot out of the
exhaust.
(12/10/2013)
When activated, the HC Doser
sprays a small amount of diesel
fuel (the HC) into the exhaust. The
catalyst in the DOC reacts with
the HC to generate heat. The heat
is used to clean (regenerate) the
DPF by reducing the trapped soot
to ash.
•
A vehicle with a DPF has up to
two additional indicator lamps on
the dashboard. The two additional
lamps, along with the check
Y53–1190–1C1
engine lamp, alert the operator of
the status of the DPF.
CAUTION
Do not submerge or allow water to enter the DPF assembly. Components of
the assembly can be damaged and affect the performance of the aftertreatment system. Failure to comply may
result in equipment or property damage.
NOTE
Refer to your engine manufacturer’s
Operator’s Manual for diesel particulate filter (DPF) maintenance information.
NOTE
Refer to your vehicle or engine manufacturer’s Operator’s Manual for additional information on the engine indicator lamps.

Diesel Particulate Filter (DPF) System
NOTE
Ultra low sulfur diesel (ULSD) fuel is
required for engines equipped with an
aftertreatment diesel particulate filter.
If ULSD is not used, the engine may
not meet emissions regulations, and
the DPF or aftertreatment diesel oxidation catalyst (DOC) can be damaged.

Selective Catalytic Reduction (SCR) System
Selective Catalytic
Reduction (SCR) System
Overview
The SCR system is composed of
several main components:
1.
Diesel Emissions Fluid (DEF)
Controller
2.
DEF Dosing Unit (DEF Module)
3.
DEF Dosing Valve
4.
SCR Catalyst
is sprayed into the exhaust gas prior to
the SCR catalyst. The DEF vaporizes
and decomposes to form carbon
dioxide and ammonia. The ammonia
reacts with the NOx emissions over the
aftertreatment SCR catalyst to form
nitrogen and water.
DEF:
•
may have a slight ammonia smell
•
is colorless
•
is non-toxic and non-polluting
•
is non-flammable
NOTE
It is unlawful to tamper with, modify, or remove any component of the
SCR system. It is also unlawful to
use DEF that does not meet the specifications provided or to operate the
vehicle/equipment with no DEF.
