Cetane number (minimum 51): indicates the ignition quality. A fuel with a low cetane number may cause problems when starting from cold and have a negative effect on combustion.

Viscosity (2.0/4.5 centistokes at 40°C): this is the resistance to flow and performance may decline if not within the limits.

Density (0.835/0.855 Kg/litre): a low density reduces the power of the engine, and density that is too high increases performance and opacity of the exhaust

Distillation (85% at 350°): this is an indication of the mixture of different hydrocarbons in the fuel. A high ratio of light hydrocarbons may have a negative effect on combustion.

Sulphur (maximum 0.2% of the weight): high sulphur content may cause engine wear. In those countries where diesel has a high sulphur content, it is advisable to lubricate the engine with

The countries in which diesel normally has a low sulphur content are: Europe, North America and Australia.

FUELS FOR LOW TEMPERATURES

It is possible to run the engine at temperatures below 0°C using special winter fuels. These fuels reduce the formation of paraffin in diesel at low temperatures. If paraffin forms in the

diesel, the fuel filter becomes blocked interrupting the flow of fuel.

Fuel can be:

For all fuel types, the cetane number cannot be lower than 51.

AVIATION KEROSENE AND RME FUELS (BIOFUELS)

The use of these fuels is allowed. However they may condition the performance of the engine. The only Aviation fuels that may be used in this engine are: JP5, JP4, JP8 and JET-A if

5% oil is added. For more information on Aviation fuels and Biofuels (RME, RSME) please contact the Lombardini applications department.
