Engine, description 200 Service Information 2014/10/30
Profile:
EXC, EC250D NL [GB]
Engine, description
Engine D8H is a straight six-cylinder, four-stroke, turbocharged diesel engine with direct injection and intercooler. The
engine meets governing legislation according to Tier 4 interim for exhaust emissions.
The engine features a Common Rail Fuel System controlled by the Engine Electronic Control Unit (E-ECU). The engine with
ACT (Advanced Combustion Technology) features split injection and turbocharger with mechanical wastegate. The Exhaust
Aftertreatment System (EATS) is equipped with a Diesel Oxidation Catalyst (DOC) and a Diesel Particulate Filter (DPF) to
reduce the particulate content in the exhausts. Cooled Exhaust Gas Recirculation (EGR) reduces NO contents and reduces
emissions. All electronic functions in the engine are controlled by Volvo's Engine Management System, EMS2.2.
For more information, see:

293 Exhaust Gas Recirculation (EGR), description
The cylinders are numbered in sequence, starting at the flywheel. Ignition order: 1-5-3-6-2-4. The engine's rotational
direction is counter-clockwise, seen from the flywheel side.
Engine identification
2. Figure 1
Identification plates
The engine's serial number is stamped on the cylinder block's side. The identification plates on the cylinder block's side and
on the valve cover contain model designation, serial number, manufacturing country, recommended fuels, and so on. The
identification plates also include emission-related supplementary information. The engine's model designation and serial
number must be indicated when ordering spare parts.
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 functions that can be activated are:
High coolant temperature
3.
High inlet manifold air pressure
High inlet manifold air temperature
High oil temperature
Low oil pressure
Low coolant level
High temperature of cooled EGR exhausts after the EGR-cooler
High crankcase pressure
High temperature of EGR actuator
High soot load
High differential pressure across Diesel Particulate Filter (DPF)
High exhaust temperature
High ECU temperature
High DPF temperature
EATS air pump failure
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
shut down 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 may request engine protection, such as:
High Altitude (ensures that high compressor charge-air temperature is never reached)
Low Coolant Temp
Crank Sensor Failure
Gear Ratio
Regeneration
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.
For more information, see .
387 Central warning
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 the 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 machine's speed 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
is 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 fault and/or at 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 a
real compression test.
23017-3 Feed pressure, inspection Used when there is a suspicion of fault and/or at abnormal values/readings.
23712-3 Injectors shut off, manual Used when there is a suspicion of fault and/or at abnormal values/readings.
23777-3 Fuel system, check Check the fuel system on common rail engines.
In this test, it is possible to check the engine at different running condition.
25410-3 Air pump exhaust aftertreatment,
test
Used when there is a suspicion of fault and/or at abnormal values/readings.
Air for combustion and HC injection
25411-3 Burner exhaust aftertreatment, test Used when there is a suspicion of fault and/or at abnormal values/readings.
25433-3 Fuel system exhaust aftertreatment,
bleeding
Used to remove any air in the EATS system.
25438-3, Nox sensor, age compensation,
reset
Used to reset the age compensation value stored in the MID 128, E-ECU.
A reset is needed either when the E-ECU is replaced and there is no
possibility to read out the values from the old E-ECU or when a new Nox
sensor is mounted.
25440-3 Fuel pressure, exhaust
aftertreatment system, test
The test checks;
The fuel supply to the shut off valve, pressure and temperature
The pressure after MV1 to the HC injector
The pressure after MV2 to the burner
25456-3 Exhaust aftertreatment diagnostics Perform a simple check of the included components in the exhaust
aftertreatement system.
25457-3 Diesel Particulate Filter Service
Regeneration
Used when the soot load level becomes higher than what can be removed
by the normal regeneration process.
See 254 Exhaust Aftertreatment System, description
25460-3 Reset soot and ash load When the diesel particulate filter has been changed, the soot load and the
ash load must be reset. The reset is needed to indicate to the system that
the filter has been cleaned.
The soot load and ash load must only be reset if a clean filter has been
installed.
27502-2 Engine speed control, test Used when there is a suspicion of fault and/or at abnormal values/readings.
28407-3 Sensor values, monitoring Used when there is a suspicion of fault and/or at abnormal values/readings.
28420-3 Flywheel and camshaft signal, test Used when there is suspicious of faulty signals or faulty connected sensor.
