SECTION II
ENGINE SPECIFICATION

2.1 Engine Description


The 6M19 series diesel engines are direct injection engines. The engines are
controlled with a mechanically actuated fuel injection pump. The engine cylinders
are arranged in-line. The cylinder head assembly has two inlet valve and two
exhaust valve for each cylinder. Each cylinder valve has two valve springs.
Each piston is provided with two compression rings and an oil control ring. It is
important to ensure the correct piston height so that the piston does not contact the
cylinder head. The correct piston height also ensures efficient combustion of fuel
that is necessary in order to conform to requirements for emissions. The crankshaft
for a four cylinder engine has five main bearing journals. End play is controlled by
the thrust washers that are located on the rear main bearing.
The timing gears are stamped with timing marks in order to ensure the correct
assembly of the gears. When the No. 1 piston is at top center compression stroke,
the teeth that are stamped on the crankshaft gear and the camshaft gear will be in
alignment with the idler gear and the fuel injection pump.
The crankshaft gear turns the idler gear which then turns the camshaft gear and the
gear for the engine oil pump.

The fuel injection pump is mounted in the gear case cover. The fuel injection
pump conforms to requirements for latest emissions. If any adjustments to the fuel
injection pump timing and high idle are required you must refer to your Baudouin
authorized service Centre. Some fuel injection pumps have mechanical governors
that control the engine speed. Some fuel injection pumps have a governor that is
electrically controlled.
A gear rotor oil pump is located in the center of the idler gear. The engine oil pump
sends lubricating oil to the main oil gallery through a pressure relief valve and
an engine oil filter. The rocker arms receive pressurized oil through an externally
located oil line that runs from the main oil gallery to the cylinder head.
Coolant from the bottom of the radiator passes through the belt driven centrifugal
water pump. The coolant is cooled by the radiator and the temperature is regulated
by a waxen thermostat valve.
Engine efficiency, emission controls, and engine operation life is directly dependent
on correct operation and maintenance as recommended by the company.
Engine performance and efficiency also depend on the use of recommended fuels,
lubrication oils, and coolants. Read the manual carefully to get familiarized with the
engine and its operation and maintenance procedure.

OPERATING INSTRUCTION

3.1 Safety precautions for operation of diesel engine


Before the engine is started, the operator must understand the operating method;
master the working principle of diesel engine and understand its power limit.
During starting and running of engine, lack of experience and careless operation
may cause fatal accident. However, if the operator has mastered the operating
technique and understood the power limit in advance, and is carefully operating,
then the personal injury caused by accident can be completely avoided.

3.2 General instructions


Proper attention and care of engine will ensure optimum performance, long life and
more economical operations.
• Follow daily maintenance as per the guidelines.
• Ensure all meter and gauges are in operational conditions.
• Running the engine on idle speed must be limited to 3~ 4 minutes. Idling the
engine for longer periods will cause carbon to clog injector spray holes and
piston rings
• Do not operate the engine with low engine body temperature for longer period.
If the engine temperature becomes too low (≤60˚C), raw fuel will dilute the lubricant.
Fuel mixed lubricant could not provide proper lubrication between the moving
components.

3.3 Preparation for first start


When preparing to start a new or overhauled engine, perform all the operations
listed below. Failure to follow these instructions may result in serious engine
damage. The operator must be familiar with all the instruments, gauges, and
controls which are needed to operate the engine. Understand the locations and
function of the following: Oil pressure indicator, low oil pressure warning indicator,
coolant temperature indicator, high coolant temperature warning indicator etc.
Closely monitor the overall engine performance and if any abnormal sign like
excessive blow by, overheat, excessive consumption of fuel or lube oil, abnormal
vibration or noise, change in exhaust gas color etc. is noticed, turn off the engine
immediately and rectify the cause of trouble. Engine damage may be avoided by a
quick response to early indications of problems.

System-wise checks
Carry out a system wise check to avoid any mistakes or points left out before the
first start of engine.

3.3.3 Checking the oil level


Check the oil level by using the oil dipstick provided in the crank case near to
the charging alternator (figure3.8). Safe oil level range is marked on the dipstick
bottom. If the oil level is in between the high level and low level area, then the oil
is at the proper level for engine operation. (Figure 3.9) If necessary, top up the oil
through the oil filling port. Do not overfill

Immediately clean up any oil spillage to avoid personal injury


CAUTION

3.3.4 After an extended storage


If an engine is non-operational for an extended period of time (for above 6 months
or above), chances for water dilution in lube oil due to air humidity. Water mixed
lube oil cannot provide adequate lubrication and may cause severe damages
to various internal engine components. For this reason, Baudouin recommends
replacing the engine oil with filters after extended storage.
The lubricating oil film on the rotating parts and bearings of an engine (which has
been in storage for six months or more), may be insufficient when the engine is
started for the first time. Hence it is necessary to pre lubricate the engine before
start up.

3.3.5 Pre-lubricating the engine


To ensure instant lubrication of all bearing surfaces at initial engine start up, prepare
the engines as follows: (For long storage)
Manually lubricate the turbocharger bearings and spin the shaft by hand several
times. (Figure 3.10, 3.11 and 3.12)
Keep the fuel shut off lever of the FIP in the “STOP” position. Switch on the panel
display of the controller
Crank the engine with the help of starter motor for 3 to 4 times till the oil pressure
is displayed on the pressure gauge/panel display.
Each cranking duration should not last for more than 10 seconds.

3.3.6 Fuel system

Fuel tank capacity: Refer the Gen-set manual


Ensure that the fuel tank is clean and dry before filling the diesel to the fuel tank.
Fill the tank with the recommended fuel.
Always keep the fuel tank in maximum level to reduce water condensation - which
is necessary to protect the injection system sub-assemblies like FIP & Injectors.
Filling the tank to the maximum level will also reduce the chance for microbe growth
and protecting the fuel tank inner wall from corrosion.
For detailed fuel oil specification, refer section V.
Properly check the fuel system for loose connections and leaky
joints. Loose connection or damaged sealing will cause air to enter
into the system

(FIP) for several times till the low pressure system get pressurized (figure 3.13).
Remove trapped air from the system stage by stage. The fuel filters, FIP and the
high pressure line is filled with fuel when assembled and tested in the factory. In
normal case, no air bleeding is required after the FIP.

Figure3.13

3.3.8 Fuel returning


When installing, prevent the fuel return pipe from contacting with hot parts (e.g.
exhaust manifold, turbocharger, and exhaust gas recirculation pipe) of the diesel
engine. There should be no throttling area in the fuel return pipe. The fuel return
pipe should not touch any sharp edges, should not be folded to form sharp corners
or even twisted. Incorrect installation of fuel return pipe will cause fuel leakage to
the engine.
Fuel return of 6M19 electronic controlled power generating series diesel engine is
internal fuel return through the cylinder head. In this manner, the injector mounting
hole is located in the cylinder head, so it should be ensured that fuel return is
completely free of leakage.

3.3.9 Air intake system
This system is assembled in the factory and taken necessary performance trial.
However make sure the tightness of all clamps in the system. Also make sure there
is no blockage in the air filter inlet mouth.

3.3.10 Exhaust system


This system is also assembled in the factory and taken necessary performance
trial. However make sure the tightness of all fasteners in the system before the first
start. Also make sure there is no blockage in the exhaust outlet mouth.

3.3.11 Electrical system


The engine control and safety is managed through electrical system. This includes,
start, stop, parameter monitoring and safety stop of the engine in case of parameter
goes beyond the set limit. The electrical system is operated by 12V DC supply.

The main electrical sub-assemblies of this engine are:


1. Starter motor
2. Charging alternator
3. Pressure sensor
4. Temperature sensor
5. Speed sensor
6. Actuator
7. Controller
8. Speed Controller
A brief description about each sub assembly is mentioned below:
1. STARTER MOTOR: The starter motor is used to crank the engine at minimum
required speed to start up the engine. It drives the engine through a pinion
gear engaged with the flywheel ring gear. . The pinion disengages soon after
the engine gets started.

2. CHARGING ALTERNATOR: This alternator is designed to generate continuous


DC output voltage in 24-28 Voltage range with 25 Ampere current. This sub
assembly is mounted on the engine and driven by a B type V belt. It is powerful
enough to charge a 12V lead acid battery with a maximum capacity of 180 Ah.

3.
Go to CON
PRESSURE SENSOR CUM SWITCH: A resistive type pressure sensor cum
switch is used in the lube oil system which is mounted on the main oil gallery.
The controller will monitor and display engine oil pressure according to the
change in resistance of the sensor. The measuring range of the sensor is 0-10
Kg/Cm2

4. TEMPERATURE SENSOR: A resistive type temperature sensor is used in the


coolant system and it is mounted on the thermostat housing assembly. The
controller will monitor and display engine coolant temperature according to the
change in resistance of the sensor. The measuring range of the temperature
sensor is 0-110 °C.

5. SPEED SENSOR: A magnetic pickup is essentially a coil wound around


a permanently magnetized probe. When discrete ferromagnetic objects-such
as gear teeth, turbine rotor blades, slotted discs, or shafts with keyways-are
passed. through the probe’s magnetic field, the flux density is modulated. This
induces AC voltages in the coil. One complete cycle of voltage is generated
for each object passed

Go to CONTENT 14
6. ACTUATOR: The actuator is installed in the engine, its installation location
and method depend on specific circumstance, we recommend installing the
actuator produced by For trust with the pump in an integration installation way,
but under some special circumstances or some specific requirements, you can
also use the way of external installation.
The output shaft of the actuator and the injection pump rack of the engine
joint directly, with output in a straight line and the output displacement of 10-
30mm.After installation, the initial position shall guarantee that the pump can
have fuel cut reliably and the pump rack stroke and the actuator stroke shall
cooperate well. Generally, it is required to ensure the stroke from fuel cut to
fuel full to be about 75% of the actuator’s working stroke. There are several
connecting ways between output connecting rod of the actuator and the pump
rack, which must ensure there is no jam or slippage after installation. The
installation shall realize the purpose of no clearance transmission between the
output connecting rod and pump rack.

7. CONTROLLER: A controller is a safety device that is used for the complete


Genset control and protection. For engine safety, the controller will monitor
the speed; lube oil pressure and coolant temperature. Based on the engine
technical requirement, an alarm and or safety stop value is set in the controller.
In case the measured value exceeds the set value, the controller will generate
an alarm or stop signal and protect the engine before it reaches the unsafe
condition.

3.3.12 Engine starting and stopping


The engine can be started and stopped by manual and auto mode. The customer
can choose the starting option according to the generator application. Please
consult your nearest Baudouin service center to set up the operation mode.
The starting and stopping sequence is a general guideline. Please
refer the respective generator controller manual for more specific
and customized operating procedures.

Manual Mode
Starting: Switch on the power supply to the controller. Ensure that the battery is
healthy and power supply voltage is 12V. Check the warning, fault and timer status
on the controller display. Clear the faults if any, before the starting attempt. (Refer
the controller manual for details)
Press the start button; the signal will pass to starter motor relay and crank the
engine at desired minimum cranking speed. Normally the engine should start at
first attempt. However if the engine is idle (not started) for long period, repeat the
starting procedure 3-4 times. Between every starting attempt, there should be a
time delay of 30 - 60 seconds. If the engine is not started within 3-4 attempts, stop
the attempt, check and rectify the cause of starting trouble.
After starting the engine, pay attention to the operation parameters such as lube
oil pressure and engine speed. The parameters should be stable and achieved
the minimum required value as mentioned in the parameter table. Also check the
engine for any leakages or abnormal sound, vibration, smoke etc. Then increase
the speed from idle to rated speed. Apply the load gradually.
Go to CONTENT 16
Stopping: Before stopping the engine, make sure the load is completely removed
from the engine. Then bring down the engine speed from rated to idle (1500 to
750RPM). Run the engine in the idle speed for 2-3 minutes. Then press the stop

3.3.13 Running in period
The engine components are made of materials with different thermal expansion
and stability. It should gradually bring to the thermal stability during the initial stage
of operation. First 60 hours of operation is considered as running in period. During
this period, engine needs to be run with care at normal load (80 to 85% maximum).
Aggressive operation and over loading during running in will disturb thermal stability
and leads to shortened engine life.

3.4 Regular operation


Practice the daily inspection and maintenance for trouble free, safe and reliable
engine performance (refer below table 3.1)

DAILY INSPECTION AND MAINTENANCE


BEFORE START UP
• Ensure oil level is correct.
• Ensure coolant level is correct.
• Ensure sufficient fuel level in the fuel tank.
• Drain out water and impurities from fuel water separator and filter respectively
• Ensure the belt tightness is sufficient, and that there is no crack, peel off etc
• Ensure no leakage from any of the fluid systems - coolant, oil, fuel, etc.
• Ensure all electrical control system is in order and ensures the battery is
healthy
• Ensure all the hoses are free from leakage, not developed any cracks
• Ensure sufficient greasing wherever required (water pump, belt tensioner Pul-
ley etc.).
AFTER STARTING
Keep the engine on rated speed for 2 -3 minutes and let it warm up.
• Ensure no leakage in the fluid system - Coolant, oil etc.
• Observe the oil pressure, oil temperature, coolant temperature are normal.
• Observe the engine operation and ensure no abnormal noise, vibration, etc.
Observe the exhaust smoke is normal.
• Ensure no variation in engine speed (hunting etc.)
Table 3.1

19 Go to CONTENT
Record basic engine parameter during early life of the engine.
Monitor every parameter during routine inspection and maintenance.

Go to CON
Gradual drop in oil pressure is the indicator of progressive wear
in internal parts. If any abnormal change in parameter is noticed,
shutdown the engine immediately. Find out and rectify the cause of
trouble before restart.

3.4.1 Engine starting and warm up


The engine idle speed, rated speed and time to accelerate the speed from idle to
rated speed is pre-set by the OEA. Do not touch the throttle lever while starting the
engine. Engines should start and stabilize in the specified idle speed without any
aid.
After the engine is started, it takes a while for the lubricating oil to re-establish
the required oil film in between moving parts. The most appropriate clearance
conditions between moving parts are obtained only when the engine parts reach
the normal operating temperature.
In case of emergency Genset application, the customer should choose “AUTO”
mode on the controller. In this mode the engines get started automatically and go
for loading in case of main power supply failure. The auto operation parameter will
be set by the ASC/OEA representative during the installation and commissioning
of the Genset.
3.4.2 Monitoring the engine oil
Always maintain the correct oil level in the sump. Too high and very low level will
be a threat to engine safety. During warm-up period, engine should be loaded
gradually, until it reaches the temperature of 60°C. Required oil pressure will ensure
enough oil flow to various engine sub-assemblies and parts. Oil pressure will vary
depending on viscosity and oil viscosity depends on temperature.

Never operate the engine with very low or very high oil level (Refer
CAUTION dipstick mark)

3.4.3 Monitoring the engine coolant


Maintain the correct coolant level in the radiator. Coolant is the media to maintain
the engine body temperature within the specified range (75°C to 95°C). Maintaining
engine body temperature in the required range will ensure proper fit and clearance
between the moving parts.
If there is no coolant in emergencies, slowly add coolant with temperature not too
lower from the coolant filler, until the coolant becomes over-flown. Finally cover the
filler cap.

Do not check oil or coolant level while engine is running

OK OK

CAUTION

3.4.4 Monitoring the exhaust gas


Healthy engine operation and performance can be properly pointed out by the
engine exhaust gas. A chocked air cleaner, poor grade fuel or over-fueling, wrong
mechanical adjustments may cause a smoky exhaust. Action should be taken
immediately to find out the route cause and rectify the fault. If any serious color
change is noticed, stop the engine and carry out the inspection procedure. Refer
below table 3.2 for monitor and analyzing the exhaust gas.

Caution for operation

Go to CON
After starting the engine, let it run at idle speed for a few minutes (2-3 minutes),
then run at rated speed and apply a partial load.
Apply full load only when the fresh water outlet temperature is higher than 60°C,
and oil temperature is higher than 50°C. Increase the load gradually. Avoid sudden
application or removal of load.
In normal operation of the engine, it is allowed to operate continuously at described
rated power. However, the permissible over-load is 110% of the rated power.
Duration for permissible overload is strictly limited to 1 hour within every 12 hours.
Mixture of different grade or brands of engine oil is strictly prohibited. During
operation, always pay attention to the parameter values displayed on the panel
and observe the performance of various systems. . Even though proper and regular
inspection and maintenance practices will eliminate the chances of breakdown,
carefully check the engine for water leakage, air leakage, oil or fuel leakage during
the operation. Stop the engine if any leakage is found, and rectify the trouble.
Engine economy balancing tips

• It is most economical to operate the engine at rated power


• Carry out the inspection and maintenance according to schedule (Refer
section IV of this manual).

Operation of diesel engine in winter


1. Fuel: Select and use the diesel of different brands according to the outdoor
temperature in winter.
2. Oil: Select the oil with different viscosities according to different seasons.
3. Coolant: Select and use different brands of anti-freeze additive and add
additive in different quantity into the cooling system according to the outdoor
temperature.
4. Starting: In winter, use the auxiliary starter if required. It is allowed to run the
engine at higher speed and apply load after attaining the normal oil pressure
and water temperature.
Battery: Check the electrolyte level, specific gravity and cell voltage. If the diesel
engine is not used for a long time and ambient temperature is very low, then remove
the battery and store it in a warm room.
Shutdown: When stopping the engine in cold weather, first remove the load, then
keep the engine at idle speed for 3~4 minutes, stop the engine only after all tem-
peratures drop down. Do not drain off coolant with anti-freeze additive after the
engine is stopped. If the coolant is not added with the anti-freeze additive, then it is
necessary to open water drain valve and completely drain off all coolant. This will
prevent damages caused to the engine due to freezing.

4.7.1 Check air filter

Go to CON
Cleaned air is playing a major role for the optimum engine performance and life of
internal components. Periodically check, clean and replace the air filter to ensure
optimum performance and maximum life.

It is not allowed to use the engine without air filter, otherwise the
dust and impurities will cause aggressive wear of the internal parts.

4.7.2 Cleaning air filter


Always use clean and dry air to clean the air filter element. To make cleaning
process more efficient, always direct the compressed air from inside to outside the
element. Don’t clean air filter with diesel or water. (Refer figure 4.1).
Check the condition of the sealing rings every time the air filter is removed for
cleaning. Replace it if the same is deformed or at least once in a year.

Figure 4.1

4.7.3 Replacement of engine oil and filters


Precautions
• Never run an engine without oil.
• Do not run an engine with oil filler port open or oil dipstick taken out
Engine oil must be replaced when the additives are active. As per our standard, the
first time oil should be replaced at 50 hours. Later, it should be replaced every 300
hours or 6 months from the date of last oil change.
The oil should be as per the recommendation of the company (grade and brand).
The oil and oil filter are required to be replaced at the same time. The oil should
be drained when the engine is warm. (About 45 to 55°C).Locate the engine oil
drain plug provided on the oil sump bottom. Position a suitable bin below the drain
plug. Remove the drain plug with the help of a suitable spanner. Drain out the oil
completely.

Go to CONTENT 28
After the engine oil is drained off completely, carefully inspect the
magnetic part of the drain plug for accumulation of metal particles.
Accumulation of various metal particles is the indication of abnormal
wear of internal components. If metal particle accumulation is
noticed, Carry out necessary inspection before proceeding to the
next step.
Remove the oil filter with the help of special filter wrench. Let the oil drain out
completely from the filter housing. Take new oil filter and confirm the seal ring is
positioned on the filter mating face. Fill up sufficient quantity of fresh oil in the filter
and lubricate the sealing ring face. Position the filter and tight it on the housing by
hand. Use the filter wrench and gently tight the filter on its housing with the help of
filter wrench.
Recap the drain plug and properly tighten it with the help of suitable spanner. Fill
up the recommended engine oil up to specified level through the filling port. Check
and confirm the sump oil level with the help of dipstick provided on the crank case.
Start the engine and run it for a short period (3-4 minutes).during running check
and ensure no leakage from the filter sealing and sump drain plug. Stop the engine
and check the oil level after 5 to 10 minutes; top up if required.

4.7.5 Air bleeding from fuel system


After every filter change and maintenance of engine fuel system, or air entered into
the system, check the whole fuel system and bleed out the air from the system.

4.7.6 Adjustment of Poly V-belt Tension


6M19 series diesel engine is provided with a cog Poly V belt, which drives the water
pump and charging alternator. To ensure efficient operation of the engine, wit is
important to maintain correct belt tension. Hence it is recommended to check and
adjust the belt tension periodically.
Check the belt tension only when the engine is stopped. Press on the middle of
a straight section of the belt with a force of 30~40 N (see fig 4.8). The bending of
Poly V-belt should be within the range of 10~15 mm. If not qualified, loosen the
adjusting bolt on the adjusting bracket to move the generator to adjust the belt to a
proper tension. Excessive tension will shorten the service life of the belt and lead
to premature failure of bearings in the alternator and water pump due to the heavy
load resulted from excessive belt tension. Insufficient belt tension, however will
lead to belt creep and fracture, resulting in engine overheating.

4.7.7 Adjustment of Valve Clearances


Proper valve clearance is important for the engine efficiency and long life. Hence
it is necessary to check and adjust the clearance periodically. The checking and
adjustments are necessary due to wearing of related internal parts.

Preparation:
Adjust the clearance only when the engine is stopped and cold. (≤ 50°C)
Required Valve clearance Inlet valve: 0.30 mm Exhaust valve: 0.40 mm

Method:
Remove the cylinder head cover. Turn the crankshaft until the mark of the top dead
center of the first cylinder on the crankshaft pulley aligns with the pointer of the
timing indicator (see fig 4.11).

31 Go to CONTENT
Go to CON Figure 4.11 Figure 4.12
When the piston of the first cylinder is at its top dead center on the compression
stroke, both intake and exhaust valves of the first cylinder will be in the closed
position. In this position, check the valve clearances as per the sequence mentioned
in below table, step-1. After completing the first step rotate the crank shaft for 360°
and follow step -2 from the 6th cylinder.
If the valve clearance is found incorrect, follow the adjusting sequence as mentioned
here. Loosen the lock nut of the clearance adjusting screw with the help of spanner
and hold it. Loosen the adjusting screw with the help of a screw driver and insert
the correct feeler gauge. Screw in or out the adjusting screw until the feeler gauge
inserted between the rocker arm and the top surface of the valve stem feels neither
too loose nor too tight. Then tighten the lock nut and check the clearance again.
Readjust if necessary till it is properly set. Repeat the operation if required of other
cylinders. Once the checking and adjustment is completed, relocate the cylinder
head cover with a new gasket.

LUBRICANT AND COOLANT SPECIFICATIONS

5.1 Lubricant
5.1.1 The functioning of lubricating oil in a diesel engine

The lubricating oil used in the engine must be multifunctional. It must perform the
primary functions of:
1. Lubrication: Basic function is to reduce friction and minimize the wear and tear.
The engine oil forms a film between the moving parts (such as bearings, pistons,
piston rings, cylinder liners and the valve train) and ensures sufficient lubrication
between the moving parts

2. Cooling: Acts as a media for high heat transfer (from combustion chamber) and
protecting the moving parts from overheating.
3. Detergency: Cleaning pistons and preventing sludge build-up on internal surfaces
4. Prevention from corrosion: Corrosion prevention by neutralizing the acid and
protecting the components from atmospheric humidity by creating a layer.

5. Sealing: By filling in the uneven surfaces in the cylinder wall, valve stems and
Turbocharger oil seals.
5.1.2 Engine oil consist of
Engine oil consists of base oil and additives. Base oil is the most basic raw mate-
rials of engine oil and additives are added for enhancing the oil properties which
is suited for diesel engine applications. Basic additives are viscosity modifiers, an-
ti-wear additives, detergents, dispersant and antioxidant etc.
5.1.3 Why oil should be drained
Engine lubricating oil must be drained when it can no longer perform its functions
in an engine. Oil doesn’t wear out, but it becomes contaminated/ degraded to the
point that it can no longer satisfactorily protect the engine. The engine oil degra-
dation is a normal result of engine operation, where oil properties changed mainly
because of reaction to the combustion by products.
5.1.4 How engine oil performance is getting deteriorated

1. By-products of Engine Combustion: Soot from partially burned fuel will


contaminate the fresh oil and over a period of time, viscosity of the oil will increase.
2. Base (BN) additives become neutral due to reaction with acid, produced during
combustion process.
3. Varnish and sludge which are formed as a result of the oxidation of the oil as it
breaks down or decomposes which leads to oil thickening.thickening

4. Contamination due to dirt entering the engine through the atmospheric air and
bad fuel.
47 Go to CONTENT
5. Other additive depletion due to reaction which will affect the performance of oil.
Hence the engine oil becomes inefficient after the recommend hours.

5.1.5 Oil performance classification system

Following are the organizations designing and approving oil classification and
specification standards.
API (American Petroleum Institute)
ACEA (Association des Constructers Europeans automobiles - European) ASTM
(American Society for Testing Materials)
JASO (Japanese Automobile Standards Organization)

5.1.6 SAE viscosity recommendations


The viscosity of oil is a measure of its resistance to flow. The Society of Auto-motive
Engineers have classified engine oils in viscosity grades:
• Oils that meet the low temperature [0°F (-18°C)] requirement, carry a grade
designation with a “W” suffix.
• Oils that meet both the low and high temperature requirements are referred to
as multi grade or multi viscosity grade oils.

Multi graded oils are generally produced by adding viscosity index improver
additives to retard the thinning effects that the low viscosity base oil will experience
at engine operating temperatures. Multi graded oils that meet there requirements
of the API classifications, are recommended for use in engines.
It is recommended to use the multi graded lubricating oil with the viscosity grade
as table 5.1

5.2 Engine oil recommendations for Baudouin engines


Quality of lubricating oil is one of the key drive factors to decide the performance,
durability and total cost of operating of diesel engine. Hence, we have always been
recommending the best available/suitable engine oil to be used in our engine.
Lubricating oil has also undergone various improvements to meet the requirements
of these changes in diesel engine technology. With this, SAE 15W40grade
lubricating oil with API CI4+ classification is now available in India from most of oil
companies. This is the best engine oil currently available in India.
This provides several advantages such as,
1. Reduced wear and tear of internal moving parts like piston rings, liner, bearing,
shaft etc.
2. Better oxidation stability at high temperature
3. Stabilized engine temperature on higher loads

Go to CONTENT 48
4. Optimum lube oil consumption
5. Better emission control
6. Improved detergency for better cleanliness of internal passages and
components
7. Less sludge formation due to improved dispersancy
8. Improved capability on acid neutralization formed during combustion process,
resulting in less corrosion damage in internal engine components.

Hence, we strongly recommend the use of SAE 15W40 lube oil with API CI4+
classification
for all engines to get the various advantages and optimum performance from the
engine.
This oil should have a minimum TBN (Total Base Number) of 10.5 to counteract the
higher Sulphur content of high speed diesel available in India.

Beware of spurious oils in the market. Bad oil quality is detrimental


to engine performance. Hence oil should always be procured from
CAUTION
the original manufacturer or the authorized distributor
Lubricating oil to be used in the engine must meet all qualities as per manufacturer’s
specifications. We recommend audit checks of fresh engine oil to ensure the
quality of oil. Facility to check suitability of oil for using it in the engine is available
with the service centers. If in doubt about the quality of lube oil, contact lube oil
manufacturing company and get oil analyzed in their laboratories.
Do not intermix different brands of oil as two different brands of oils may not be
compatible with each other. It is therefore recommended that the brand which is
used for initial fill/oil change should only be used for top-up. Different brand of oil
may be used after draining all the existing oil i.e., at the oil drain interval and after
flushing the lube oil system with new brand of oil.

The responsibility of meeting oil quality lies with the oil manufacturer
and Baudouin will not be responsible for problems occurring on
CAUTION
engines due to poor quality of oil.

5.3 Grease Recommendations


We recommend the use of grease meeting the specifications of ML-G-3545,
excluding those of sodium or soda soap thickeners. Contact lubricant supplier for
grease meeting these specifications.

49 Go to CONTENT
Do not mix brands of grease can cause damage to bearings
Excessive lubrication is as harmful as Inadequate lubrication.

Go to CON
CAUTION After replacing fan hub replace both the pipe plugs. Use of fittings
will allow lubricant to be thrown out, due to relative speed.

The responsibility of meeting oil quality lies with the oil manufacturer
and Baudouin will not be responsible for problems occurring on
engines due to poor quality of oil.

5.4 Coolant
An engine coolant is a heat transfer fluid which flows through or around an engine
to prevent it’s overheating, transferring the heat produced by the engine to radiator/
heat exchanger that dissipates it. An operating engine typically converts only one
third of the energy derived through the combustion of fuel into work. The other
two thirds is converted into heat, of which one third goes out with the exhaust and
remaining one third is removed by engine coolant. The coolant absorbs this heat,
transport it to the radiator/heat exchanger and dissipate it into the environment/
atmosphere.
Research has shown that 40% of all engine problems in high speed diesel engines
are related, directly or indirectly, to improper cooling system maintenance.
