1.1 Engine nomenclature

The engine specification class

Ú

 The engine specification class (CL or VM) is described in the specifications table.

1.2 Specifications

NOTE:

1)The information described in the engine specifications tables (the next page and after) is for "standard"

engine. To obtain the information for the engine installed in each machine unit, refer to the manual pro-
vided by the equipment manufacturer.

2)Engine rating conditions are as follows (SAE J1349, ISO 3046/1)

• Atmospheric condition: Room temp. 25 °C, Atmospheric press. 100 kPa (750 mm Hg), Relative humidity

30 %

• Fuel temp: 25 °C (Fuel injection pump inlet)
• With cooling fan, air cleaner, exhaust silencer (Yanmar standard parts)
• After running-in hours. Output allowable deviation: ± 3 %

1.3 Fuel oil, lubricating oil and cooling water

1.3.1 Fuel oil

IMPORTANT:

Only use the recommended fuel to obtain the best engine performance and to keep the durability of the
engine, also to comply with the emission regulations.

(1) Selection of fuel oil

Diesel fuel oil should comply with the following specifications.
• The fuel specifications need to comply with each national standard or international standards.

•  ASTM D975  No.1-D, No.2-D ------------- for USA
• EN590:96-------------------------------------- for EU
• ISO 8217 DMX -------------------------------------- International
• BS 2869-A1 or A2 ---------------------------------- for UK
• JIS K2204    ---------------------------------------- for JAPAN

The following requirements also need to be fulfilled.

• Cetane number should be equal to 45 or higher.
• Sulphur content of the fuel 

It should not exceed 0.5%by volume. (Preferably it should be below 0.05 %)

• For alternative fuel (Bio fuel such as FAME, JP-8), please contact YANMAR.
• Water and sediment in the fuel oil should not exceed 0.05% by volume.
• Ash should not exceed 0.01%by mass.
• 10% Carbon residue content of the fuel 

It should not exceed 0.35%by volume. (Preferably it should be below 0.1 %)

• Aromatics(total) content of the fuel 

It should not exceed 35% by volume. (Preferably it should be below 30%
and aromatics(PAH*) content of the fuel preferably it should be below 10%)
PAH*:polycyclic aromatic hydrocarbons

• DO NOT use Biocide.
• DO NOT use Kerosene, residual fuels.
• DO NOT mix winter fuel and summer fuel.

Note : Engine breakdown can be attributed to insufficient quality of fuel oil.

(2) Fuel handling

• Water and dust in the fuel oil can cause operation

failure. Use containers which are clean inside to store
fuel oil. Store the containers away from rain water
and dust.

• Before supplying fuel, let the fuel container rest for

several hours so that water and dust in the fuel are
deposited on the bottom. Pump up only the clean
fuel.

(3) Fuel tank

Fuel tank inside should be always clean enough and dry
it inside for the first use.

Drain the water according to the maintenance (section 5)
with a drain valve.

(R.1))

Pump up only the fuel
in the upper half to
leave dregs near the bottom

1.3.2 Lubricating oil

IMPORTANT:

Only use the recommended engine oil to keep the durability of the engine.

(1) Selection of lube oil

Engine oil shoud comply with the following specifications.

1)Classification
• API classification 



 CD, CF, CF-4, CI-4

TBN value : 

º

9(CD), 

º

9(CF), 

º

7(CF-4), 

º

7(CI-4)

• ACEA classification 



 E-3, E-4, E-5

TBN value : 

º

10(E-3), 

º

10(E-4), 

º

10(E-5)

• JASO classification 



 DH-1

TBN value : 

º

10(DH-1)

The oil must be changed when the Total Base Number (TBN) has been reduced to 2.0.

*TBN(mgKOH/g) test method; JIS K-2501-5.2-2(HCI), ASTM D4739(HCI)

DO NOT use The following engine oils.
• API : CG-4 , CH-4
• ACEA : E-1, E-2 , B grade
• JASO : DH-2 , DL-1

Reason

API CG-4, CH-4
In case CG-4, CH-4 is to be used for YANMAR TNV diesel engine series, there is a possibility that
excessive wears occur on the valve train system due to the content of oil.

ACEA E-1,E-2, B 
These fuels are developed for the different type of diesel engines.

JASO DH-2, DL-1
These fuels are developed for the different type of diesel engines.

2)Viscosity

Selection of viscosity will be determined depending
on the ambient temperature.
(Refer to the chart on the right.)

The following requirements are also need to be
fulfilled.
• Standard engine oil service interval is 250 hrs or

every 12 months.

• DO NOT add any additives to the engine oil.
• DO NOT mix the different types (brand) of engine

oil.

• DO NOT use synthetic oil.
