Engine, description
Engines D11F, D13F, and D16F are straight six-cylinder, four-stroke, direct-injected diesel engines. Engines D13F and D16F
are equipped with a single turbocharger with wastegate and engine D11F has a turbocharger without wastegate. They have
charge-air cooling with mechanically actuated electronically controlled unit injectors, controlled by the EMS-system.
The engines have a one-piece cylinder head with four valves per cylinder and a single overhead camshaft. Rear-mounted
timing gear results in a shorter engine and lighter drivetrain installation. Engine brake for Articulated Hauler; VEB+ (EPG,
Exhaust Pressure Governor, and VCB, Volvo Compression Brake).

Identification plate 1
A label located on the valve cover showing the engine's component ID-number, serial number, manufacturing site, engine
part number, and engine build date, as well as their bar codes. Manufacturing sites:
A = Skövde, Sweden
E = Curitiba, Brazil
F = Flen, Sweden
L = Lyon, France
The engine's serial number, part number, and manufacturing site are stamped into the engine's cylinder block.
The hardware component number of the Engine Control Unit (ECU) is located on a label on the back of the ECU.
The certification label is located on the valve cover as well as the machine's frame.
Automatic Engine Shutdown
This is a function used to automatically shut down the engine after idling for a certain time. The operator is informed and
has the opportunity to cancel the function within one minute, either by increasing the engine speed, shifting gear, or by
activating the hand throttle.
Engine protection
The ECU contains functionality designed to protect the engine from damage during extreme operating conditions or from
further damage when an essential engine component fails. There are several proactive functions, and different applications
have different functions activated. The ones that can be activated are:








High coolant temperature
High intake manifold air pressure
High intake manifold air temperature
High oil temperature
Low oil pressure
Low coolant level
High crankcase pressure
High ECU temperature
Various protective actions such as warning lights, engine torque reduction, engine speed limitation, and vehicle speed
limitation may be taken when the above functions reach dangerous levels that may damage the engine. In order to always
allow the operator to move a machine away from an unsafe situation, there is a delay of at least 30 seconds before the
protective actions (such as forced idle and forced shutdown) are activated after a Key-ON. If the engine has been forced to
shutdown or forced to idle due to an active engine protection function, the operator can obtain a 30 second delay by
powering down the EMS with a Key-OFF for 7 seconds and then a Key-ON (the EMS is powered down by the Vehicle-ECU
(V-ECU) after the ignition key has been in its OFF position for approx. 7 seconds). In addition to the above protective
functions, other software functions could request engine protection, such as:





High Altitude (ensures that high compressor discharge temperature is never reached)
Turbo OverSpeed
Low Coolant Temp
Crank Sensor Failure
Gear Ratio
Warning lights
There are two levels for warning lights, an amber caution light and a red stop light.


The amber light indicates a warning situation
The red light indicates that the vehicle must be stopped.
Engine torque limitation
The engine torque can be limited by the engine protection function. Engine torque limitation is active until the parameter

has reached a safe level or until the EMS is powered down.
Forced Idle
The engine can be forced to idle speed by the engine protection function. Forced idle is active until conditions triggering the
problem are back within normal working range or the EMS is powered down.
Engine Shutdown
The engine can be forced to shut down after conditions have reached levels that may cause engine failure and the machine
speed is below a specified value.
Machine Speed and Engine Speed Limits
The engine protection function can limit the speed of the vehicle and/or the engine's rpm.
Levels of engine protection
Available proactive functions depend not only on the application but also on what level of protection has been activated for
the specific machine. Two levels of engine protection are offered, the standard level is Basic protection and the optional level
Extended protection. The general difference between basic and extended engine protection is that no active actions such as
forced idle and forced shutdown will be taken in basic engine protection (with the exception of crankcase pressure that can
cause shutdown in either setup). Warnings will be given to the operator regardless of engine protection level.

VCADS Pro, Operations
The following VCADS Pro operations are available for function group 2. Operations used when changing or working on
components are mandatory.
Tests
Operation Application
20046-3 Read out engine information The operation is used to read out the engine emission and engine certificate
information when requested by the customer or other interested parties.
21006-3 Cylinder compression, test Used when there is a suspicion of malfunction and/or in case of abnormal
values/readings.
This test indicates if there is any deviation in compression in any cylinder in
relation to the other cylinders.
As a first check this operation is both easy and fast to perform instead of an
actual compression test.
23016-3 Cylinder balancing, test Used when there is a suspicion of malfunction and/or in case of abnormal
values/readings
This test indicates if any of the injectors deviates too much in fuel injection
so that the engine's characteristics deteriorate.
23017-3 Feed pressure, inspection Used when there is a suspicion of malfunction and/or in case of abnormal
values/readings.
23712-3 Injectors shut off, manual Used when there is a suspicion of malfunction and/or in case of abnormal
values/readings.
25410-3 Air pump exhaust aftertreatment,

Used when there is a suspicion of malfunction and/or in case of abnormal
values/readings.
25411-3 Burner exhaust aftertreatment, test Used when there is a suspicion of malfunction and/or in case of abnormal
values/readings.
25412-3 Components ASU, test This sub-test is used to check the functions of the atomizer air valve, the
main air valve, the fuel shut-off valve, and the fuel pump.
25457-3 Diesel Particulate Filter Service
Regeneration
Used when the soot load is above 1.7.
See 254 Exhaust Aftertreatment System, description
Before starting service regeneration, check the differential pressure across
the diesel particle filter so that it is within stated value according to the
service information. This is to make sure that the DPF will not be damaged
by the service regeneration.
After the service regeneration and when the exhaust temperature has
stabilized to a normal level, check the differential pressure across the DPF
again so that it is within stated value according to the service information.
This is to determine that the filter has been regenerated correctly and that it
is not clogged with ash.
25537-3 Variable geometry turbo function
test
When there is a suspicion of malfunction and/or in case of abnormal values/
readings.
26385-3 Reversible cooling fan, test When there is a suspicion of malfunction and/or in case of abnormal values/
readings.
27102-3 Accelerator pedal, test In case of abnormal values/readings.
28407-3 Sensor values, monitoring When there is a suspicion of malfunction and/or in case of abnormal values/
readings.

sensor.
