Properties of Diesel Fuel
What are the properties of diesel fuel?
The properties of diesel fuel are at times varied from other fuels such as gasoline, however there are also some similarities such as the fact that they both burn in a fuel cylinder to make the engine work and it goes without saying that they both power vehicles.
But how different are gasoline and diesel fuel really?
There are several differences between the properties of gasoline and diesel fuel, for example:
• Diesel requires less refining
• It is heavier, thicker and oilier
• It has an increased evaporation time
• It can be compressed more
Diesel is used to fuel and power a large range of vehicles, including:
• Farm equipment... the list goes on!
More technical properties of diesel include:
• Centane number: minimum 40 (as of 2000)
• Cloud point: -34 degrees celsius (maximum)
• Water and sediment: 0.02% (maximum volume)
• Microbiological contamination: Bacteria - SRB causes corrosion and sludge development
• Fame content (biopart): approximately 7%
• Density: 0.832 kg/L
• Sulphur content: 500ppm
• CFFP - cold filter plugging point: up to -5 degrees celsius
• Heating (calorific) value: 45.5MJ/kg
• Flash point: 40 degrees celsius (minimum)
• Viscosity: (at 40 degrees celsius) 2.5-3.5mm2/s
• Carbon residue: 0.1% (maximum mass)
• Ash: 0.01% (maximum)
• Oxidation stability: up to 0.025mg/ml
