yes, there is no difference between them except the gov. requires kerosene to have a red dye additive which will turn your exhaust reddish in color. a flag for the troops, it is illegal to use it in place of diesel and you will be fined to hell


nonesense

there is a big difference

and red dyed diesel (called derv in the uk) is not kerosene



yes it is. DERV = diesel engined road vehicle. Kerosene is heavier than diesel and has a lower flash point and you won't get as much inginition from compression as you would with diesel.

Diesel is simply a different fractional distillation product of crude oil....the resulting mixture of carbon chains in the hydrocarbons that comprise diesel fuel typically contain between 8 and 21 carbon atoms per molecule.

Kerosene is distilled from crude oil at much lower temperatures, resulting in a mixture of carbon chains that typically contain between 6 and 16 carbon atoms per molecule.

About Diesel Fuel
By Bill King 12/8/2000
With all of the recent talk about using Kerosene (number 1 diesel) as a motor fuel and the differences between grades of Diesel Fuel, I thought I would pass along to the group my short course on refined petroleum.

In the hierarchy of refined petroleum products from highest to lowest (from a gaseous state, then liquid, to solid) are: natural gas; "wet" natural gas; high-octane aviation gasoline; automotive gasoline; finished kerosene; home heating oil; diesel fuel; industrial fuel oil; finished lubricating oils; waxes and paraffin's; gas oil; coke and finally asphalt. Also moving from highest to lowest, the viscosity, or stiffness, of the refined product increases. For example, at room temperature, automotive gasoline flows much more freely than finished lubricating oils.

Diesel fuel lies in the middle of the refined petroleum hierarchy and is considered one of the middle distillates -- slightly heavier than kerosene and slightly lighter than industrial (bunker) fuel oil. Like automotive gasoline, diesel fuel is refined into several sub-categories or grades. From highest to lowest viscosity are Number 1 Diesel Fuel (1-D), Number 2 Diesel
Fuel (2-D) and Number 4 Fuel Diesel (4-D). There used to be a Number 3 Diesel Fuel (3-D), but it is no longer refined.

Number 4 Fuel Diesel Fuel is slightly lighter than industrial fuel oil and is used in low and medium speed engines that operate at a constant or near-constant speed, such as stationary power plants or railroad locomotives. Even though Number 4 Fuel Diesel Fuel has an ignition quality similar to Numbers 1 and 2 Diesel Fuel, it is too thick to work well in a truck engine where the load on the engine is constantly changing and requires varying amounts of fuel to be injected into the cylinders.

Just above Diesel fuel in the middle distillate category is Kerosene. Like Number 4 Fuel Diesel Fuel, Kerosene has an ignition quality similar to Numbers 1 and 2 Diesel Fuel. But unlike Number 4 Fuel Diesel Fuel, which is too thick, Kerosene is too thin to work well as an engine fuel. The thickness of the diesel fuel itself acts as a lubricant to prevent wear of the engine's fuel injectors. This lubricating quality of diesel fuel is why some Old-timers still refer to it as "Diesel Oil." Adding a common lubricant to Kerosene usually decreases its ignition quality.

Numbers 1 and 2 Diesel Fuel are the primary fuel for mobile diesel engine applications. Number 1 Diesel Fuel is commonly labeled at the pump as "Premium Diesel" or with a Cetane number of 44 or 45. It is not as thick as Number 2 Diesel Fuel and for this reason is the choice for motorists during the cold winter months. The disadvantage of Number 1 Diesel Fuel is that it does not have the lubricating qualities associated with Number 2 Diesel Fuel. While Number 2 Diesel Fuel has a higher lubricating quality than Number 1 Diesel, its thickness can cause rough starting in a cold engine and rough-running in cold weather. Number 2 Diesel Fuel is usually labeled at the pump with a Cetane number of 40.

Home Heating Oil is closest to Number 2 Diesel Fuel in ignition quality and lubricating ability. But before anybody rushes to put this non-road taxed fuel in their truck, consider this: refiners don't intend Home Heating Oil to be used in an internal combustion engine and the furnace fuel that is sitting in your basement tank may or may not have the smoke suppressants, ignition accelerators and biocides to kill fungi and bacteria that we generally assume to be present in the Diesel Fuel at the pump
