Fuel quality requirements for diesel engines
General requirements
Volvo Penta diesel engines are certified for compliance with emission legislations with the diesel test fuels
specified by law. These fuels correspond with diesel fuel standards EN 590, ASTM D975 and JIS K2204 and
paraffinic diesel fuel standard EN 15940. Volvo Penta guarantees compliance with emission legislation and
fulfillment of expected lifetime as long as the specified restrictions are followed.
It is the responsibility of the fuel suppliers to always ensure that their fuels meet relevant requirements and are
fit for their intended purpose. Their responsibility includes any use of additives for proper engine performance and
function.
Special requirements are placed on cold-flow properties, that is, temperature limit values of fuel filterability during
operation in winter conditions.
For IWW stage V, only diesel fuels according to EN 590 and EN 15940 is approved for use according to emission
regulations. The engine must be used as intended and serviced according to operators manual to fulfill the exhaust
emissions.
Restrictions for specified diesel fuels
•
Max density for ASTM D975 No 2–D: 860 kg/m
Insufficient density reduces the power and increases the fuel consumption. Excessive density endangers
the durability and function of the fuel injection equipment.
• Max lubricity (wsd 1.4) for JIS K 2204: 460 μm
Sufficient fuel lubricity is essential to protect the fuel injection system against excessive wear.
Restrictions for other diesel fuels
Volvo Penta also approves the use of other diesel fuels as long as the here specified restrictions are followed.
However Volvo Penta does not guarantee compliance with emission legislation or fulfillment of expected lifetime
with these other diesel fuels.
NOTICE! Operators must check permission for usage of these fuels according to regional, national or local
regulations.
