Diesel fuel is any liquid fuel used in diesel engines , which use fuel ignition without a spark, thanks to the compression in the inlet air mixture and the injection of the diesel fuel. Named after Rudolf Diesel, who experimented with these engines in the late s to early s, diesel fuel is a widely used source of petroleum fuels throughout the world. The most common type of diesel fuel is called petrodiesel, which is diesel fuel derived from petroleum.
There are also a few non-petroleum diesel alternatives like biodiesel, synthetic diesel, and biomass to liquid. Diesel fuel starts its cycle as crude oil that needs to be harvested.
The first process is called separation. This heat causes the crude oil to separate into liquid and gas. The top of the tower is a different temperature than the bottom, which is how the separation is made possible.
In the top of the tower will be propane gas, the middle of the tower is where diesel is found, then the bottom of the tower is all the lubricants. The next step in the process is called conversion, which has a catalyst used on the heavier oils.
This step is able to create additional propane, diesel, and gasoline. Last edited by mclaren : 2nd May at Proudly powered by E2E Networks. User Name. Remember Me? New Topics. Mark Forums Read.

What are the differences between these two propellants? Conventional diesel and petrol are both produced from mineral oil, but the precise refining methods vary.
Diesel is in principle easier to refine than gasoline, however it contains more pollutants that must be extracted before it can reach the same levels of emissions as petrol. The calorific value of diesel fuel is roughly Crude oil contains hundreds of different types of hydrocarbons all mixed together and, depending on the source of the crude oil, different impurities.
In order to produce petrol, diesel or any other oil-based products, the hydrocarbons have to be separated, by refining of one type or another:. Different hydrocarbon chain lengths all have progressively higher boiling points the longer the chain, so they can all be separated by a process known as fractional distillation.
During the process, crude oil is heated in a distillation column, and the different hydrocarbon chains are extracted as a vapour according to their vaporisation temperatures and then recondensed. After distillation, there are various techniques that are used to convert some fractions to others:. For example, this allows a refinery to turn diesel fuel into petrol fuel, depending on the demand for petrol.
Refineries will also combine various fractions processed, unprocessed into mixtures to make desired products. For example, different mixtures of hydrocarbon chains can create petrols with different octane ratings.
Distillated and chemically processed fractions are treated to remove impurities, such as organic compounds containing sulphur, nitrogen, oxygen, water, dissolved metals and inorganic salts.

Emissions and the Catalytic Converter A catalytic converter is a housing that contains porous metal filler located between the engine and muffler in the exhaust system.
Viscosity Viscosity is the single most important property of a lubricant. Additive Levels Diesel engine oil has more additives per volume. About the Author. Jeremy Wright. Related Articles.
