The cloud point of a clear distillate fuel is the temperature at which the fuel
becomes cloudy because of the appearance of wax crystals.
||In the ISO Standard 8217 cloud point is only prescribed for DMX grade,
"bright clear" distillate fuels for emergency diesel and lifeboat
Compliance with this parameter ensures that the fuel is suitable for use in
ambient temperatures down to -15oC without heating the fuel.
||If a distillate fuel has a high cloud point and the engine is operating in
cold climates wax crystals will form which can lead to fuel starvation and
failure of the engine.
