Section 5Engine Fluids700 SeriesFuel specificationTo get the correct power and performance from yourengine, use good quality fuel. The recommended fuelspecification for Perkins engines is indicated below:Cetane number . 45 minimumViscosity . . . . . . 2.0/4.5 centistokes at 40˚CDensity . . . . . . . 0,835/0,855 kg/litreSulphur . . . . . . . 0.2% of mass, maximumDistillation . . . . . 85% at 350˚CCetane number indicates ignition performance. Afuel with a low cetane number can cause cold startproblems and affect combustion.Viscosity is the resistance to flow and engineperformance can be affected if it is outside the limits.Density: A lower density reduces engine power, ahigher density increases engine power and exhaustsmoke.Sulphur: A high sulphur content (not normally foundin Europe, North America or Australasia) can causeengine wear. Where only high sulphur fuels areavailable, it is necessary to use a highly alkalinelubricating oil in the engine or to renew the lubricatingoil more frequently, see table below:Aviation kerosene fuelsIf there is a requirement to operate with these fuels,contact Perkins Service Department before the fuel isused.Fuel sulphur content (%)Distillation: This is an indication of the mixture ofdifferent hydrocarbons in the fuel. A high ratio of lightweighthydrocarbons can affect the combustioncharacteristics.Low temperature fuelsOil change interval1.0 50% of normalSpecial winter fuels may be available for engineoperation at temperatures below 0˚C. These fuelshave a lower viscosity and also limit the wax formationin the fuel at low temperatures. If wax formationoccurs, this could stop the fuel flow through the filter.If you need advice on adjustments to an enginesetting or to the lubricating oil change periods whichmay be necessary because of the standard of theavailable fuel, consult your nearest PerkinsDistributor or one of the companies listed on page 8.05/99Printed in England© Propriety information of Perkins Engines Company Limited, all rights reserved33364 51-19M-1-SM 01-29-02 57.4400.0100
