MARCH 2004

To obtain the best engine performance, it is essential not to
deviate from the mission profile for which it was produced
and set up.The engine must not be used for purposes other
than those stated by the manufacturer. IVECO MOTORS is
willing to examine any need for par ticular installations
beforehand. Use of an electronically controlled injection sys­tem, in providing the engine with performance benefits,
requires that the installer and maintenance specialist comply
with some fundamental rules, which will become more and
more commonplace as use of such equipment becomes
progressively more widespread. Boat outfitters and mainte­nance specialists are invited to closely follow the instructions
contained herein. No modifications to the engine, its acces­sories and components, are allowed.

Failure to comply with the instructions that follow shall
void the warranty and relieve IVECO MOTORS of all lia­bilities.

For personnel safety

Specialists and installers are cautioned to comply with
workplace safety rules and to adopt prescribed individual
protection devices when working.

❏ Drain the cooling, lubrication and fuel lines only after the

fluids have duly cooled.The pressurized cap of the water
line may be opened only after the engine has duly
cooled.

❏ Batteries contain a highly corrosive sulfuric acid solution:

must never be upset and must be handled with the
utmost caution to prevent spillage. Ensure that the bat­tery compartment is adequately ventilated.

Handling

The engine must be handled by experienced personnel,
using the prescribed tool or a rocker arm that keeps the lift­ing lines parallel and with adequate equipment in terms of
capacity and size. The two eyebolts provided for lifting the
engine alone must always be used simultaneously.

Installation

❏ Knife switches or battery breakers may be used on the

power supply line of the engine electronic unit, provided
they are not used to shut the engine off.

❏ Do not modify the wiring harnesses; their length may

not be modified: use only available extensions.

❏ Do not use electronic device wiring harnesses not com-

pliant with the IVECO MOTORS directive, in terms of
length, type of conductor, location, clamping, connection
of the shielding and earth braids.

❏ To avoid any interference, the wiring harnesses of the

different on-board electronic devices must follow differ­ent paths from those of the engine electronic systems.

❏ Do not connect any extraneous user device to the

engine electrical equipment.

❏ Do not place voltage across the boat’s on-board electri-

cal system without first verifying that there are no short
circuits.

❏ Do not branch pipes off to draw fuel from the engine

supply lines.

❏ Do not make any change to the engine’s hydraulic cir-

cuits and components.

❏ Do not execute arc welding operations before remov-

ing the electronic units from their seating, placing them
at an adequate safety distance.

❏ Do not subject electronic units to temperatures exceed-

ing 80 °C.

❏ Do not paint electrical components and their connec-

tions.

❏ Do not alter the data contained in the engine control

electronic unit.

❏ Comply with prescribed procedures and torque values

when tightening threaded elements.

Start-up

❏ Ready the engine following the procedure set out in

Chapter 17.

❏ When star ting the engine the first time, have suitable

means available to cut off air intake in case of a runaway
condition.

❏ Start the engine after ensuring that it is complete with

every par t specified by the manufacturer and required
by the installation, without attempting to start it with
caps and occlusions to the lubrication, cooling and fuel
feed lines.

❏ Check that the fluid lines are perfectly sealed, especially

lines for fuels and lubricants, which may cause fires and
consequent harm to persons and equipment.

❏ Make sure that the various pipelines are not in contact

with warm surfaces or moving par ts.

❏ The installing yard is required to carr y out tests to veri-

fy the functional compatibility between the electrical­electronic equipment of the engine and the other elec­tronic equipment present on the boat.

Tests and tuning up

❏ Never disconnect the batteries when the engine is

running.

❏ Remove the electrical connections from the batteries

before any operation on the electrical system.

❏ Ensure that the battery terminals comply with the exact

polarity, are properly tightened and protected against
accidental short circuits and corrosion phenomena.

❏ Do not connect or disconnect electrical connections

when electrical power supply is present.

❏ Do not cause sparks in the attempt to verify the pres-

ence of electrical voltage.

❏ Do not draw fuel through unfiltered lines.

❏ Do not clean the engine and its parts with corrosive or

abrasive detergent substances, to avoid compromising
the integrity of electrical connections.

4. GENERAL INSTALLATION CRITERIA

Accessibility

The engine must be located in such a way as to allow filling
and draining engine liquids when doing ser vicing operations.
Moreover, the relay box and the diagnostic push-button pre­sent on it must be accessible, also when underway.

Anchoring

If anchoring is accomplished by interposing shock mounts,
they must be able to support the engine’s mass and the lon­gitudinal thrust exerted by the propeller shaft in motion.
If rigid mounting is adopted, particular care must be given to
support alignment and co-planarity.
Information on dimensions and fastening values are provided
in the “Installation Diagram”.

Combustion and ventilation air

Compliance with prescriptions on the quantity of air
required for combustion and ventilation assures a regular
operation of the engine even in adverse conditions and it
enables to deliver its maximum design power (1).

Sea water line

It must be provided with an intake capable of preventing the
entry of foreign bodies into the suction pipes. Between the
intake and the pump, it is best to interpose a gate to be
closed in emergencies or for extended idle periods and a fil­ter to stop the smaller impurities; it is also recommended to
install a suitably dimensioned and easily replaced zinc anode.
The engine sea water line was provided by the manufactur­er with protection anodes to be replaced periodically.
The rubber hoses positioned along the pipeline shall be suffi­ciently rigid not to create choked areas caused by crushing (1).

Engine pre-heating

If the engine usage profile requires immediate delivery of
power at the highest rpm’s, it is recommended to install an
auxiliary pre-heater on the closed cooling loop.

Exhaust gas discharge

The exhaust gas discharge conduit shall be compliant with
the guidelines contained in the IVECO MOTORS publication
“Guide to the installation of marine engines”; it also provides
indications to compute the dimensions of the exhaust
pipelines, which is the Yard’s responsibility.

Electric - electronic equipment

Provide a suitable arrangement of the engine control elec­tronic unit, of the relay box and of the possible optional elec­tronic units, referring to the dimensions and position of the
wire harnesses and their connectors.
Both units must be anchored in such a way as to dampen the
vibrations and stresses undergone by the hull while under­way and/or induced by the engine’s operation.

(1) The EDC engine electronic control is programmed to

reduce maximum deliverable power if the operating
parameters measured by the sensors show that critical
conditions have been reached, and if exceeded the
engine could be damaged.

N60 ENT M37INSTALLATION DIRECTIVE

13

MARCH 2004

For the installation, the following connections are required:

- from the tank to the pre-filter

- from the pre-filter to the pump inlet

- from the fuel discharge outlet to the tank

Pre-filter

The pre-filter with priming pump, supplied separately from
the engine, must be fastened near the tank, in a relatively low
point of the line to allow for easy replacement of the filter­ing car tridge and/or the operation of the hand pump. Avoid
the use of additional mesh or paper filters along the feed
lines between pre-filter and engine. To avoid introducing
impurities in the feeding lines inside the engine, do not place
filter cartridges pre-filled with fuel in the system.

Materials’ Characteristics

The fuel tank and the suction and return assembly must
withstand the continuous abrasion caused by a flow of fuel
oil of 250 l/h at a temperature of 120 °C without noticeable
deformation or wear or release of material. Use of metal
tanks, preferably made of iron alloys, is allowed,provided they
are connected to the negative terminal of the battery to pre­vent the accumulation of electrostatic charges.

Tanks must be provided with vents to avoid exceeding an
internal pressure of ± 5kPa (± 0.5 m of H

2

O column); their
shape and the suction assembly must be such as to assure a
suction at the maximum longitudinal and transverse inclina­tion allowed for the boat, with a residual quantity of fuel oil
considered “reserve”.
The suction inlet should be positioned in such a way as to
avoid taking in sludge.The return flow must be in such a way
as to facilitate the mixing of the returning fuel with the fuel
in the tank. If the tank is lower than the filter, then the return
pipe must always be submerged.The pipes and union fittings
of the fuel line must withstand a fuel oil flow rate of 250 l/h
at a temperature of 120 °C and a pressure of 3 bar (300
kPa) without noticeable deformation, wear or release of
material. Metal tubes, preferably made of iron alloys, are rec­ommended, taking care to connect each individual segment
to engine ground to avoid the accumulation of electrostatic
charges and inserting a vibration damper elastic joint on each
segment. The pipes used must be certified according to the
relevant Countries’ rules or to the standards issued by clas­sification Bodies.

The electrical equipment of the engine comprises a series of
components provided separately from the engine to enable
an easy and diversified installation, according to the Yard’s
design choices.The need to make accessible, at sea or under­way, the controls to the electrical components and to the
connector for diagnostics contained in the relay box may be
met through different installation arrangements.
Along with the coupling of all connectors provided in the
wire harnesses, completing the installation also requires the
connecting wire harness (12) for the sensor for the presence
of water in the fuel (13), to complete the power line and to
connect the accumulator to the engine wire harness.

Engine wire harness.

The connection of the +B terminal of the alternator to the
positive +30 terminal of the electric starter motor must be
achieved with a conductor having a cross section of at least
10 mm2.The connection of the positive +30 terminal of the
electric starter motor to the positive pole of the battery,
achieved with a conductor having a cross section of at least
70 mm2, allows to obtain, as shown in the figure, the simulta­neous connection of the alternator to the battery. The con­nection between the engine ground and the negative pole of
the battery must be achieved according to the guidelines
provided in the Engine electrical ground paragraph.

CAUTION

If magneto-thermal protecting breakers are inserted, they
must not be used to stop the engine and in any case they
must be activated only a few seconds after shut-down.

Supplementary services battery

To assure that the engine can be star ted with a sufficient
quantity of energy, it is advisable to provide for the installa­tion of a supplementar y batter y, dedicated to supplying
power to the on-board electrical services.The power line to
recharge it may be constructed according to the indications
provided in Chapter 24.

If one engine is installed

The batter y used for ser vices may be recharged interpos­ing on the power supply line a relay actuated by the
recharge signal of the alternator’s electronic regulator
(D+).

If two engines are installed

The presence of two generators allows to keep the recharg­ing functions separated: the generator (G1) recharges the
battery (AC1) dedicated to starting both engines and pow­ering both electrical/electronic control circuits, whilst the gen­erator (G2) recharges the battery (AC2) used to power the

services. In two-engine applications, it is essential to connect
the engine grounds to a common potential; the solution pro­posed in Chapter 24 fully complies with this need, assuring
the full functionality and independence of the two circuits.

Engine electrical ground

The connection of the engine electrical ground is achieved
by connecting with a cable of at least 70 mm2cross section
to the negative pole of the battery to the tightening point of
the electric starter motor as shown in Figure 14.

1. Point of connection of the engine electrical ground.

To anchor the grounding terminal to the engine, proceed as
follows:
Completely remove the conducting paint from both parts
constituting the connection, using mechanical means or suit­able chemical product; if the anchoring operation is to take
place on superficially treated par ts, completely remove the
anaphoretic paint with mechanical means, obtaining a
smooth support surface.
Apply a uniform layer of BH44D paint (IVECO standard 18-

1705) with a brush or spray gun.
Join the parts constituting the grounding note within 5 min­utes from the time the paint was applied.

This is accomplished through the power supply line of the
electric starter motor and connection to the +B of the alter­nator. The electronic regulator of the alternator that equips
the engine allows an effective control over the batter y
recharging operation.
If, due to installation requirements, the batteries need to be
positioned at a distance from the engine, we recommend
increasing the cross section of the power line conductors
and verifying recharging effectiveness by measuring voltage
across the batter y poles.

The connection of the central electronic unit, ECU, to the
components of the EDC system is achieved by means of
three connectors to subdivide the wiring harnesses, thereby
favoring a quicker identification of the lines during testing
operations.
The different connectors are polarized and provided with
levers to favor the connection and disconnection operations
and assure proper coupling.
They are dedicated to the following functions:

❏ Connector A for engine mounted components

❏ Connector A1 reserved for electro-injector connection

❏ Connector A2 for boat side connections

Relay box

This shall be installed and anchored in such a way as to
dampen the vibrations and stresses occurring when under­way, and they shall be accessible during servicing operations
and when underway.The electrical commands positioned on
the panel allow to control engine star ting and stopping (2)
directly from the engine room, while excluding any possibili­ty that anyone may involuntarily start the engine from the
bridge (1), during servicing operations. Among the controls
present on the panel are also the push-button (3) and the
“blink code” light indicator (4), useful to obtain, also while
underway, indications that will lead to identify failures or
improper engine operating conditions (see Chapter 20).

On the relay box is located the multipolar connector, pro­tected by a screw-on lid (5), for connection with the com­puterized diagnostic tools prescribed by IVECO MOTORS
(see Chapter 20).

Inside the box, anchored to a printed circuit board, are pre­sent the power management relays of some components
and the elements that protect the electrical lines against
short circuits or excessive current absorption.These compo­nents perform a similar function to that of fuses, almost total­ly avoiding the need to restore the electrical continuity of cir­cuits subjected to an anomaly condition. These components
are able to limit and eliminate shor t circuit currents without
melting, restoring their own and the circuit’s electrical conti­nuity, once the cause of the anomaly is removed.

Throttle lever position sensor

After testing the working condition of the linkage, adjust the
run of the ser vo components (see Chapter 18).

❏ With the throttle at idle setting, the potentiometer rod

has to be in the resting position.

❏ With the throttle at the stop, the potentiometer rod has

to be in the position of maximum run out.

Installation

In order to drill holes on the area where the panel is to be
mounted, refer to the dimensions indicated in Chapter 11.

Operation of the panel

After completing the electrical connections and engine
preparation, perform the tests required for the first start, as
described in Chapter 18.
Verify the proper operation of the panel, proceeding as
follows:

❏ Make sure that the “ENGINE ROOM / BRIDGE” switch

of the Relay Box is in the “BRIDGE” position, then turn
the key switch to the first position and verify that the
instruments are powered and the indications and alarms
module runs the alarm test for about 5 seconds accord­ing to the procedures set out below.

❏ Once the test is complete, only the indications pre-

scribed for the engine not running must remain lighted:
e.g.“alternator charge” and “low oil pressure”; the analog
instruments must provide values consistent with the rel­evant physical parameters.

Testing the engine start function

Turn the key switch to the second position and keep it in it
until the engine has started, then release the switch, which
will stably return to the first position; after releasing the key,
the switch may be brought back to the starting position only
after the switch is returned to the resting or zero position.

Checking indications

After starting the engine, verify whether the operating
modes of the indications and alarms module are similar to
those set out below.
Using appropriate measuring instruments, verify the consis­tency of the indications provided by the analog instruments.
Verify the indication of the panel revolution counter, com­paring it with the one measured by a reference instrument;
if the indication is different, proceed as described below.

Testing the engine stop function

The engine is stopped and the panel is disabled by returning
the key switch to the resting or zero position.
The panel has an engine stop push-button whose function is
only enabled in versions where the engine stops as a result
of the excitation of an actuator, i.e. engine versions requiring
certification by Certification Bodies.

Indications and alarms module

1. Runaway engine (SSV) - 2. Presence of water in fuel pre­filter (SAC) - 3. Low coolant level (SBLA) - 4. Alternator

fault (SS) - 5. Clogged oil filter (SIFO) - 6. Clogged oil vapor

filter (SIFB) - 7. Pre-lubrication (SP) - 8. Clogged air filter

(SIFA) - 9. Clogged fuel filter (SIFC) - 10. High coolant
temperature (SATA) - 11. Low oil pressure (SBPO) -

12. Pre-post heating (SCP) - 13. EDC malfunction (EDC).

The indications and alarms module comprises the indicator
lights and the electronic alarm interface, timing and storage
circuit. It is programmed in such a way that when it is pow­ered, all indicator lights are lighted, with the exception of
those for “pre-lubrication”,“pre-post heating” and “EDC” fail­ure and a sound signal is emitted by the buzzer.
The sound alarm may be silenced before the end of the test,
acting on the appropriate control.
During the starting phase and for the subsequent 15 sec­onds, needed to stabilize the low oil pressure signal, all the
module’s functions are inhibited; once this time interval has
elapsed, every alarm state detected by the sensors will cause
the associated indicator to be lighted and the buzzer to be
powered; the exceptions are the “pre-lubrication” and “pre­post heating” indicators, given only visually.
When a new alarm state is detected, the indicator light will
flash to highlight the occurrence with respect to any others
which may be ongoing at the time.When the sound alarm is
shut off, the light indicator will remain lighted and the alarm
will be stored until the engine is stopped.

The standard set-up of the N60 ENT M37 provides for use
of the indicators SAC, SS, SIFA, SATA, SBPO, EDC.

17. PREPARING THE ENGINE
FOR FIRST START-UP

18. TESTS BEFORE
THE FIRST START-UP

1. Drain the residual 30/M protective oil from the sump.

2. Pour into the lubricating loop only lubricating oil of the
type and in the quantities set out in the Refilling Table.

3. Drain the CFB protective liquid from the fuel loop, com­pleting the operations as indicated under item 3. of
Chapter 23.

4. Remove the caps and/or seals from the engine intake,
exhaust, aeration and venting por ts, restoring normal
conditions of use. Connect the inlet of the turbocharger
to the air filter.

5. Connect the fuel loops to the boat tank, completing the
operations set out in item 4. of Chapter 23. During fill­ing operations, connect the pipe returning fuel to the
tank to a collecting container, to prevent residues of CFB
protective liquid from ending up into the boat tank.

6. Verify and refill engine coolant as prescribed.

7. Remove from the engine the labels with the inscription
“ENGINE WITHOUT OIL”.

Although they are extremely impor tant, “common sense”
checks such as the exposure of sensitive parts (plastics, wire
harness, electronic units, etc...) to heat, and those that for
years have characterized the quality of the work performed
in the yard, are not mentioned herein.
Tests of the proper operation of the engine and the com­ponents of the electronic control system may be performed
rapidly and with the utmost reliability using specific diagnos­tic tools, available from IVECO MOTORS Technical Assis­tance Centers.

Fuel tank suction

Verify the fuel suction at the maximum allowed longitudinal
and transverse inclination, with the residual quantity of fuel
considered “RESERVE”, such as to cause the reserve indica­tor light to be permanently lighted.

Throttle lever position sensor

In the positions of minimum and maximum travel, verify the
correlation between the position of the throttle control
valve on the bridge and the position of the sensor rod,
checking:

❏ That in the resting position the safety switch inside it

is electrically open. Carr y out the test with an ohm­meter between the points D and E of the poten­tiometer connector.

- Value read ∞Ω= optimal adjustment;

- Value read 1 kΩ = a better mechanical adjustment of

the resting position is required, to bring the value back
to ∞Ω.

❏ In the position of maximum acceleration, the rod of the

sensor has reached the mechanical end stop.

Instrument panel

Verify the efficiency of all light indicators, as described in the
related Chapters.

19. FIRST ENGINE START

Before starting the engine, check the levels of the lubricating
oil and of the engine coolant, and complete venting the air
from the fuel feed loop, acting on the hand pump of the pre­filter or with the aid of a dedicated electrical pump.
Loosen the vent fitting on the pre-filter and operate the
pump until only fuel without air flows out.
Tighten the vent fitting and continue pumping during the ini­tial start-up phases.
Make sure that the fuel that flows out of the fitting is not dis­persed in the environment.

CAUTION

Never attempt to vent the high pressure system, as this is
useless and extremely dangerous.

Start-up procedures

The electrical equipment of this engine allows to start it from
the “engine room” and from the “bridge”.

Starting the engine from the bridge

This is allowed only if the Relay box switch (1) is in the
“BRIDGE” position.
Start the engine and let it run until the idling rpm has fully
stabilized (see also the Chapters on the instrument panels).

Starting the engine from the “engine room”

Moving the Relay box switch (1) to the “ENGINE ROOM”
position (which must absolutely not be done when the
engine is running), regardless of the position of the key
switch on the indicator and control panel, enables the use of
the adjacent STOP - START push-button (2).
It will thereby be possible to start and stop the engine with
complete independence from the bridge controls.
Moving the switch (1) back to the “BRIDGE” position,
inhibits use of the “START-STOP” push-button positioned
on the Box, allowing the engine to be star ted only from
bridge controls.

RPM control

To allow easily to control engine RPM from the “engine
room”, a simultaneous acceleration/deceleration function
(SET+/SET-), active only when the switch (1) is in the
“ENGINE ROOM” position, has been implemented in the
“start” function.

Acceleration (SET +)

If, when the engine is running, the “start - stop” push-button
is held down in the “start” position, then engine rpm are pro­gressively increased; the increase ends when the push-button
is released, allowing the engine to run at the desired rpm.

Deceleration (SET –)

Moving the “start - stop” push-button back to the “start”
position, after releasing it during the rpm increase phase, a
progressive reduction in rpm is obtained; when the push-but­ton is release, the function is inhibited and the rpm reached
at that point is maintained.

NOTE: Further action on the push-button will alternatively
increase - decrease engine rpm.
The “stop” function takes priority and always stops the
engine.

CAUTION

Never operate the “BRIDGE - ENGINE ROOM” switch
when the engine is running.

Once the first star t-up phase is complete, verify that:

❏ There are no liquid leaks from the coolant loop pipeline

junction hoses.

❏ There are no exhaust gas leaks into the hull.

❏ Complete the instrument panel operation tests as

described in the related Chapters.

❏ Verify that the power supply voltage across the battery,

after about 15 minutes with the engine running, is no
less than about 13 V.

❏ Stop the engine and delete any “errors” which may have

been stored in the injection system ECU during the sta­bilization phases. For the deletion procedure, refer to
Chapter 20.

20. EDC ANOMALIES INDICATION

Anomalies indicator light

The ECU continuously monitors, with complex self-testing
routines, its own operating conditions as well as those of the
components connected to it and of the engine.
When anomalies are detected, the alarm indicator light on
the indicator and control panel is lighted in manners that
provide a first indication on the severity of the problem.

Light off: no anomaly detected or slight anomaly

that does not compromise operating
safety

Light on: significant anomaly, allowing to proceed to

a service center

Blinking light: severe anomaly requiring immediate

repairs. If possible, shut the engine down.

Blink code

The emission of the anomaly codes detected during self­testing and stored in the ECU starts after pressing and
releasing the “CHECK” push-button on the relay box panel,
when the “BRIDGE - ENGINE ROOM” switch is in the
“ENGINE ROOM” position
The LED located at the side of the push-button and the
EDC indicator light on the indicator and control panel will
simultaneously signal, with two series of emissions at differ­ent frequencies, the blink codes that indicate the anomaly
with decimal numbering.

Slow blinks identify the area of the anomaly (engine, injec­tors, ...), fast blinks identify a specific anomaly.

Every time the push-button is pressed and released, only one
of the stored codes is emitted; therefore, the procedure
must be repeated until an error indication identical to the
first one is obtained, which means the entire error memory
has been analyzed.

If no anomalies are stored, the light comes on when the
push-button is pressed and comes off about 1 second after
its release, without any subsequent blinking.

Recovery

The recognition of significant or severe anomalies causes the
adoption of strategies that allow to use the engine with com­plete safety, guaranteed by limiting performance within pre­set thresholds according to the severity of the case.

These strategies cause the reduction of the maximum values
of torque and power delivered by the engine.
In the case of intermittent anomalies, i.e. recognized by the
ECU and subsequently no longer present, performance
reduction will continue until the engine is shut down.
Normal operation will be restored only the next time the
engine is started, while the anomaly data will be “saved” in
the failure memor y.

Error deletion procedure

A. Shut the engine down and keep the key switch in the

“OFF” position.

B. Approach the relay box. Keeping the “CHECK” diagnos-

tic push-button (3) pressed, move the adjacent “BRIDGE

- ENGINE ROOM”switch (1) to the “ENGINE ROOM”
position, while keeping the diagnostic push-button
pressed for 8 more seconds.

C. Release the push-button and move the “ENGINE

ROOM” switch to the “BRIDGE” position

At the end of this procedure, the codes of any anomalies
detected during the engine installation and first start-up
operations will be deleted in the ECU.To make sure that no
anomaly data remain stored in it, or that there are no other
errors in the system, set the “BRIDGE - ENGINE ROOM”
switch to the “ENGINE ROOM” position and verify that,
when the diagnostic push-button is pressed, the blink code
light (4) does not emit any code.

At the end of these operations, return the switch to the
“BRIDGE” position

If the ECU signals the presence of errors or operating anom­alies, the installation will have to be reviewed to remove the
cause of the error or anomaly.
Indications for decoding the codes are provided in Chapter 21.

NOTE:The blink code diagnostic procedure provides indica­tions about current anomalies as well as past anomalies that
are no longer present when the diagnosis is carried out;
therefore, it is absolutely mandatory, at the end of every
repair operation, to erase the error memory to prevent
anomalies whose cause has already been removed from
being signaled in the future.

22. UNDERWAY CHECKS

ECU Temperature

Verify that the temperature of the surface of the electronic
engine control unit, after 30 minutes underway at full engine
power, is less than +70 °C.

Engine compartment vacuum

Verify that value of ambient air pressure in the engine room
with the engine(s) at full load and maximum power output
complies with the value specified herein.

Combustion air temperature

Verify that the temperature in the engine room, after 30 min­utes underway at full engine power, does not exceed 50 °C
and, in any case, does not exceed the value of external tem­perature by more than 15°C.

Exhaust back-pressure

Verify that the value of back-pressure present at the inlet of
the exhaust gas conduit, with the engine(s) at full load and
maximum power output, complies with the value specified
herein.

Exhaust temperature

Verify that the temperature of the exhaust gases under
maximum engine power output conditions is close to the
prescribed value.To determine the propeller power absorp­tion curve, it will also be possible to obtain the fuel injection
values from the ECU parameters by using the IVECO
MOTORS tool.

Fuel temperature

Verify that the temperature of the fuel in the low pressure
line, while underway at full power and with a stable quantity
of fuel in reserve, does not exceed 70 °C. A higher value
would entail a reduction in engine performance. If the ten­dency to reach the maximum allowed temperature is noted,
install a heat exchanger for the fuel.

Pressure in the fuel supply line

To assure the regular operation of the engine and the relia­bility of the components of the fuel supply and injection sys­tem, you need to verify that:

❏ vacuum in the fuel oil supply line to the low pressure

pump is less than 0.5 bar relative (5000 mm H

2

O);

❏ pressure in the fuel oil return line to the tank is less than

0.2 bar relative (2000 mm H

2

O).

Measures are carried out inserting a “T” junction near the
fuel inlet and outlet, taking care to avoid any air suction.Val­ues are read at variable rpm, from idle to maximum, at 200
rpm inter vals.
If there are any symptoms indicating the possible presence of
air in the fuel supply line, a check may be made by inserting
a clear tube, arranged as an inverted U, before the engine
inlet junction.

23. PREPARING THE ENGINE FOR LONG IDLE PERIODS

To prevent oxidation to the internal par ts of the engine and
to some components of the injection system, if idle periods
exceeding two months are expected, the engine needs to be
prepared with six-months periodicity,proceeding as follows:

1. Drain the lubricating oil from the sump, after heating the
engine.

2. Pour 30/M protective oil (alternatively, oil conforming
with MIL 2160B Type 2 specifications) into the engine to
the “minimum” level marked on the dipstick.
Start the engine and let it run for about 5 minutes.

3. Drain the fuel from the injection line and from the filter,
taking care to avoid letting the fuel come in contact with
the auxiliaries belt.

4. Connect the fuel line to a tank containing CFB protec­tive liquid (ISO 4113) and assist the inflow of the liquid
by pressurizing the line and turning the engine over for
about 2 minutes, after excluding the operation of the
injection system.The required operation may be carried
out by directly polarizing the terminal 50 of the electric
starter motor with positive voltage 12 V, using a con­ductor prepared for the occasion.

5. Nebulize 30/M protective oil at the rate of about 60 g
(10 g per liter of displacement) into the turbocharger
intake, while the engine is turning over as described
above.

6. Close with suitable stoppers or seal with adhesive tape
all engine intake, exhaust, aeration and venting ports.

7. Drain the residual 30/M protective oil from the sump;
it may be re-used for 2 more engine preparation oper­ations.

8. Apply tags with the inscription “ENGINE WITHOUT
OIL” on the engine and onboard panel.

9. Drain the coolant, if it has not been mixed with anti­freeze and corrosion inhibiting agents, affixing tags to
indicate that the operation has been carried out.

If external parts of the engine are to be protected, spray pro­tective liquid OVER 19 AR onto unpainted metal parts, such
as flywheel, pulleys and others; avoid spraying belts, connec­tor cables and electrical equipment.
