risk.
Read carefully this manual and keep it always on hand to clarify any doubts.
Do not try to operate the equipment without knowing all controls and understanding the
operation of the main systems.
Take all precautions of safety indicated next, because they are your protection during
the work.
• Do not change the original features of the engine.
• Do not smoke while filling fuel tank.
• Clean immediately all and any spilled fluid. Put the material used on cleaning in a safe position and
discard according the Local Legislation.
• Do not fill, while engine is running, unless it is absolutely necessary.
• Never clean, lubricate or adjust an engine in operation.
• Do not adjust anything, if you do not know how to do it correctly.
• Do not operate the engine in closed rooms, because the exhaust gases are extremely “prejudicial” to
the health.
• Do not allow people or animals to stay close to the engine, vehicle or equipment while in operation.
• Do not allow people with loose clothes or long and loose hair to stay close to the mobile parts.
• Stay away from the rotary parts. Remember that helices, for example, cannot be well seen while the
engine is running.
• Do not remove radiator cap if the engine is still hot, because cooling water, under pressure, is
extremely dangerous, and may spill and cause serious injuries.
• Do not use salty water or any other substance that can cause corrosion in the cooling system.
• Avoid sparks or fire near batteries, especially while they are charging, because they can cause
explosions. The solution of the batteries could boil and its contact with the skin and eyes is dangerous.
• Disconnect battery terminals before doing any repair in the electric system.
• Seek medical assistance if diesel fuel, under high pressure, penetrates the skin.

environment preservation in Diesel engines production for the worldwide market, through an efficient
administration of its resources, processes and products.
GUIDELINES:
To attend the legislation, applicable environmental rules and other requirements that the Company has
joined.
To develop products and procedures to reduce environmental impact s and to avoid pollution.
To apply an efficient administration system that promotes the continuous improvement to reach
environmental objectives and targets.
To promote, in the Company , the sense of individual responsibility in relation with the environment.
To involve its suppliers and service suppliers in the development of habits which cooperate in the
preservation of the environment.
ENVIRONMENT
The environment preservation is a basic point in the managerial philosophy of INTERNATIONAL
ENGINES SOUTH AMERICA LTDA.
It has been approved a program of actuation that includes activities as natural resources conservation,
elimination and residues recycling, water protection, noise reduction and acoustic isolation, air purity
conservation and contaminants residues elimination.
All these subjects constitute the mark of a wide environment protection program, which is considered
since the beginning of a new product project.
The International HS 2.8L engine was released in the market and accomplishes without problems all
these requirements.
The systematical accomplishment of this philosophy can be appreciated especially in the main aspects,
like disassembly easiness, less number of materials, usage of plastics of easy recycling.
It means, equally , that materials harmful to the environment are not used, like amianthus, cadmium and
hydro-carbide fluor-chlorined.
In the same field, gases and acoustics emissions reduction are considered, as well as the improvement
of the active and passive safety.
This environment protection program is not limited only to the production process, because it is extended
to the complete cycle of useful life of the engine, considering also its wear after a long operation period.
We have assumed a commitment with the planet we live in. A commitment that we take very seriously.

Pollution Control for Auto-Motorized Vehicles - PROCONVE) and attending, in this way , to the resolutions
of CONAMA (National Council of the Environment).
Warning: The engine adjustment values specified in this manual, must be strictly observed,
because, besides to offer a better performance to the vehicle, also reduce noises and
harmful gases emissions to the atmosphere.
Warning: Any change in the fuel injection or air intake system, or even the exhaust system, may
affect directly the homologated values.

INTERNATIONAL ENGINES
TURBOCHARGER
The turbocharger is compound of a rotary turbine
and a air compressor, located in opposite sides
of a same shaft. The compressor and turbine
rotors are covered by housing denominated
compressor and turbine, which function is to
direct the gases flow through the rotors shovels.
These gases having energy in pressure,
temperature and speed form, cause the rotation
of the turbine rotor and consequently of the
compressor rotor.
With the rotation, the atmospheric air (that must
be properly filtrate) is aspired, and later on,
compressed to the compressor rotor from where
goes to turbocharging (in turbocharged
International HS 2.8L engines) and later on to the
engine cylinders. Having a higher pressure in the
intake, the work done by the cylinders is positive,
in other words, the cylinders spent a smaller
amount of energy in the intake.
In turbocharged International HS 2.8L engine, the
turbocharger is also composed by a Wastegate
valve or VNT, which controls the maximum
pressure to be provided by the compressor, to
avoid damages in the engine.
Other advantage:
Existing a larger mass of air, we can fire a larger
amount of fuel, besides we get a better
combustion of the mixture.
The operation of an engine equipped with
turbocharger does not require any special
procedure.
Anyway , to assure the maximum durability of the
turbocharger, take care of these items:
To accelerate the engine immediately after
starting damages the turbocharger, because it
gets a high speed without the oil flow need on its
shaft.
To accelerate the engine before stop it, also
damages the turbocharger, because it stops the
lubrication but, on the other hand, the turbo shaft
still has a high speed.

The intake of strange objects, even smalls, will
damage the rotor of the compressor, damaging
the operation of the turbocharger, this way,
between the recommended periods check the air
filtering system.
By working at high speeds and temperatures, the
turbo requires a lubricant oil that accomplish to
these requirements, and never should be used a
lubricant oil that does not attend to API / ACEA
specification (5th class - multi-viscous).
ACCESSORIES BEL TS
If the panel of the equipment accuses high
temperature and / or battery low charge, check if
the belt is loose or ruptured.
Two belts equip the turbocharged International HS
2.8L engine. It is very important that the belts be
installed exactly as shown in the illustration.
Two tensors adjust automatically the belts
tension, eliminating this way the necessity of
individual adjustment.
The belts must be checked at each service and
replaced when necessary.
Off-road use
Belts regular checks are essential if the vehicle is
used off-road. When executing service in the
vehicle, the owner must be contacted to identify
the way in that the vehicle’s mileage has been
get.
After each off-road use, the owner must check
the belts for cuts and damages caused by
stones. If one of the belts gets loose, it must be
repositioned correctly , replacing in the next
service or before, depending on the damage
level.
Belts conditions check
Check belts conditions, replacing them if they
present waste, cracks or contamination with oil.

will be satisfactory if it opens between
86 and 90 °C (187 and 194 °F).
Reinstallation
1. Put the thermostat with the breathe guide /
hole pin totally upwards (12 o-clock position).
2. Install the outlet elbow and a new sealing
washer. Tighten bolts within 22 to 28 Nm.
3. Invert the removal operations.

FUEL SYSTEM
PREVENTIVE MAINTENANCE
Fuel is an important factor to ensure the good
operation of the engine for a long time and without
failures.
The fuel must be clean, free of water and
impurities.
If the fuel used in the engine has to be stored, see
FUEL STORAGE.
During the engine operation, be aware to the fuel
indicator.
Fill the tank before the volume reaches the
minimum, because sedimented impurities in the
bottom of the tank can be suctioned, damaging
the filter.
Filling
1. Clean filling inlet duct cover whenever
necessary.
2. Every end of working day, fill the tank in order
to avoid the condensation of the air humidity .
Warning: After tank filling, keep it very well
closed. Never improvise. If the
cap presents any problem,
replace it to a genuine spare
part.
Warning: Bleed the system every time
the engine stops due of a fuel
lack.
Warning: Do not smoke or get close any
type of exposed blame or
sparks while filling the tank,
because diesel fuel is very
inflammable.

3. In periods of intense cold (under 0 ºC)
(32 °F), 20% of aviation kerosene can be
added to the diesel fuel. This procedure will
avoid that the existence of paraffin in the
diesel fuel obstruct the fuel piping. In the
filling, first put the kerosene and then the fuel.
Note: Only use aviation kerosene in situations when the ambient temperature is under zero.
(0 °C) (32 °F).
Fuel Filter
The filter has the function to retain the impurities
to make that the system receives a clean fuel,
avoiding this way damages in the engine fuel
injection pump and the nozzles.
Note: Use only genuine filter element.
Filter drainage
Daily , in order to avoid the premature obstruction
of the filter and to guarantee the fuel injection
pump and nozzles durability, it is necessary drain
it before the initial start, according to the Periodic
Maintenance table.
1. Open filter drainage lateral plug.
2. Open filter upper plug.
3. As soon as the fuel flows clean, through the
side plug, close the drain plug.
4. Close upper plug.
5. Check for leakages.
