Engine, description
D4E - tier 3 compliant
The D4E configuration is a four stroke, stra
ight four cylinder, turbocha
rged, direct injected diesel engine with charge air
cooling and wet, replaceable cylinder liners.
The D4E engine uses a Common Rail Fu
el System controlled by the engine el
ectronic control (E-ECU) software.
Mechanically controlled IEGR (Interna
l Exhaust Gas Recirc
ulation) reduces NO
x
formation and lowers emissions without the
need for exhaust after treatment. Volvo's
latest engine management system, E-ECU is
used to control all engine electronic
functions.
The cylinders are numbered consec
utively beginning at the flywhe
el end. Engine rotational direction is counterclockwise as
seen from the flywheel end.

Basic check, Engine
NOTE!
Certain tests and checks are performed wi
th unlocked safety locking lever. Make
sure that the machine cannot operate
unexpectedly when the contro
l lockout lever is unlocked.
Purpose of the basic check
The purpose of the basic check is to provide fast and accu
rate information about the general condition of the engine.
The basic check should be performed and evaluated ac
cording to instructions in the PC-tool VCADS Pro.
Tests included in the basic check
The basic check which is divided into the
following tests should be performed after
reading out error codes and checking
parameters
.
Tests:
1.
2.
3.
Cylinder compression, test
The purpose of the test is to show if any cylinder has
a deviating compression pressure
. The test replaces the old
pressure check method but does
not give any absolute values.
Feed pressure, test
The purpose of the test is to check that
the feed pressure is as per specification.
Sensor, test
The purpose of the test is to check the function of all sensors.

Troubleshooting
General about troubleshooting
When a malfunction is suspected or has
been confirmed, it is important to id
entify the cause as soon as possible.
The starting point for all troubleshooting is that ther
e is some type of trouble symptom or malfunction.
Malfunctions can be indicated by:
generation of error codes
detection of a malfunction symptom.
Troubleshooting work
The first step in troubleshooting is to gather information
from the operator concerning
the malfunction symptoms, see

Cylinder head, description
The cylinder head is made of grey cast iron and is common for all cylinders. The induction air enters vertically (A) and the
exhausts leave horizontally (B). Inlets
and exhaust outlets are locate
d on the same side of the cylinder block. Inlet and
exhaust valve size is increased to optimize the gas exchange
and combustion process. Valve guides are replaceable. Coolant
flow in the cylinder head is modified to accommodate an outlet controlled cooling system.
On order for the engine to fulfill govern
ing emission standards, there are 3 cylinder head gaskets of different thicknesses
between the cy
linder head and the piston.

Cylinder head, description
The cylinder head is made of grey cast iron and is common for all cylinders. The induction air enters vertically (A) and the
exhausts leave horizontally (B). Inlets
and exhaust outlets are locate
d on the same side of the cylinder block. Inlet and
exhaust valve size is increased to optimize the gas exchange
and combustion process. Valve guides are replaceable. Coolant
flow in the cylinder head is modified to accommodate an outlet controlled cooling system.
On order for the engine to fulfill govern
ing emission standards, there are 3 cylinder head gaskets of different thicknesses
between the cy
linder head and the piston.

Cylinder head gasket, description
The cylinder head gasket is a multi layered gasket with 1, 2 or 3 identification holes to indicate three different thicknesses
available. Selection of the proper thickn
ess of gasket is determined by the me
asurement of piston projection above the
cylinder block sealing surface. Recalibration for the correct ga
sket thickness would be required if new pistons or a new
cylinder block were installed.

Cylinder block, description
The cylinder block is cast in one piece and has wet, replaceable cylinder linings. Combustion pressure tensile breaking
strength in cylinder head screws is led through stiffened sections of the cylinder block wall directly to the main bearings.
The cylinder block surface should not be ground as the distance between the pistons and the valve heads may become too
small. There is also a risk that injector tips will be incorrectly placed in relation to the pistons and that exhaust values will
worsen.

Pistons, description
D6E Engine
The pistons are made of special alloy aluminium. The pi
ston's combustion compartment
has a somewhat off-center
(eccentric) position in rela
tion to the piston pin.
The pistons are provided with 3 piston rings. The fi
rst ring has a ring carrier made of cast iron.
The piston is cooled with oil spraye
d up on the inside of the piston top.
The piston cooling nozzles are made of
plastic and are mount
ed in the cylinder
head by the main bearing positions.
The first piston ring has an
asymmetric cross-section area (A). The cr
oss-section area for piston ring number two
(compression ring) is tapere
d. When installing the piston rings, the markin
g TOP by the opening in the rings must face up.
The third ring is an oil ring with bevelled edge.
