Fuel specification
To get the correct power and performance from your engine, use good quality fuel. The recommended fuel
specification for Perkins engines is indicated below:
Cetane number
indicates ignition performance. A fuel with a low cetane number can cause cold start problems
and affect combustion.
Viscosity
is the resistance to flow and engine performance can be affected if it is outside the limits.
Density:
A lower density reduces engine power, a higher density increases engine power and exhaust smoke.
Sulphur:
A high sulphur content (not normally found in Europe, North America or Australasia) can cause
engine wear. Where only high sulphur fuels are available, it is necessary to use a highly alkaline lubricating oil
in the engine or to renew the lubricating oil more frequently, see "How to renew the lubricating oil" on page 25.
Distillation:
This is an indication of the mixture of different hydrocarbons in the fuel. A high ratio of light-weight
hydrocarbons can affect the combustion characteristics.
Low temperature fuels
Special winter fuels may be available for engine operation at temperatures below 0 °C. These fuels have a
lower viscosity and also limit the wax formation in the fuel at low temperatures. If wax formation occurs, this
could stop the fuel flow through the filter.
If you need advice on adjustments to an engine setting or to the lubricating oil change periods which may be
necessary because of the standard of the available fuel, consult the Technical Service Department of Perkins
International Limited at Peterborough or your nearest Perkins Distributor.
Aviation kerosene fuels
Caution: Do not use aviation kerosene fuel JP4.
JP5 and JP8 can be used, but they can affect engine performance and wear in the fuel injector units could
increase. It is recommended that you consult the Technical Service Department of Perkins International
Limited at Peterborough if aviation kerosene fuel is to be used.
Aviation kerosene fuels are more flammable than diesel fuel and need careful storage and careful
management.
