Fuel Handling, Storage And Specification - MASSEY FERGUSON MF 300 Series Workshop Service Manual

Tractor Specification
Fuel Handling, Storage and
Specification
Diesel Fuel
Before handling fuel, filling tanks etc. , observe the
following:
Under no circumstance should gasoline, alcohol, gasohol
or dieselhol (a mixture of diesel fuel and alcohol) be added
to diesel fuel because of increased fire or explosion risks.
In a closed container such as a fuel tank they are more
explosive than pure gasoline. DO NOT use these blends.
Additionally, dieselhol is not approved due to possible
inadequate lubrication of the fuel injection system.
• Clean the filler cap area. Fill the tank at the end of each
day to reduce overnight condensation.
• Never take the cap off or refuel with the engine running
or hot.
• When filling the tank, keep control of the nozzle.
DO NOT smoke.
•
Don't fill the tank to capacity. Allow room for expansion
and wipe up spilt fuel immediately.
•
If the original cap is lost, replace it with a Massey
Ferguson cap and tighten securely. A non Massey
Ferguson cap may not be suitable.
• Keep equipment properly maintained.
Recommended 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 No . . 4 5 minimum.
Viscosity . 2/4.5 centistokes at 40
Density .... 0,820/860 kg/litre at 15
Sulphur .... 0.20% of mass, maximum.
Distillation .. 85% at 350
Cetane Number
Cetane number indicates ignition performance. A fuel with
a low cetane number can cause cold start problems and
affect combustion.
Viscosity
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 amount of sulphur can cause engine wear.
Distillation
Distillation 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
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 your nearest Massey Ferguson Dealer.
