What is the difference between Gasoline and Diesel?

Gasoline Vs Diesel

Many times, the terms gasoline and diesel are confused, both being petroleum products used as fuel in engines using different combustion cycles. diesel and gasoline

Most vehicles today use gasoline or diesel as fuel. Both are burned in the car’s engine to give it power to run. In this sense, many people are unaware of the differences between these two fuels. Therefore, in this article we will present the differences between the two based on their definitions. diesel and gasoline

What is Gasoline?

what's the difference between diesel and gasolineIt is a mixture of hydrocarbons obtained from petroleum through fractional distillation. It is used as a fuel in internal combustion engines, as well as in stoves, lamps, and solvent cleaning. In some countries gasoline is known as naphtha, in Chile as benzine. This term comes from the Greek and Latin benzene. It has a density of 680 g/L.

This word is born from the American English Gasoline, this word was never defined as a Registered Trademark, however, it seems to come from old oil lamp brands diesel and gasoline

Gasoline is obtained from direct distillation, which is the lightest liquid fraction of oil, except for gases. It is then a mixture of hundreds of individual carbides from the so-called C4 to C11.

What is Diesel?

what's the difference between diesel and gasolineDiesel fuel or gas oil is a product obtained from the distillation and purification of crude oil. This fuel is used in diesel engines, which are named after the fuel they use.

The word diesel is derived from the name of the German inventor Rudolf Diesel who in 1892 invented the diesel engine. This petroleum-derived compound contains approximately 75% saturated hydrocarbons including isoparaffins and cycloparaffins and 25% aromatic hydrocarbons including naphthalenes and alkaloidbenzenes. diesel and gasoline

On the other hand, because diesel is relatively easier to refine, since it is obtained from the fractional distillation of petroleum, its price is usually lower than gasoline. There are different types of diesel or diesel, among them are mentioned:

  • Premium Diesel or Diesel A (normally used for automobiles).
  • Subsidized diesel or diesel B (used for agricultural and industrial uses)
  • Usual diesel or diesel C (used for domestic heating).

Diesel is a liquid density hydrocarbon. It is basically made up of paraffins and is used as fuel in heating and motors.

 Its lower calorific value is 43.1 MJ/kg and tends to change with its composition. Type A diesel oil has a density of 845 g/L and is yellow and is used for passenger vehicles, class B diesel oil has a density of 855 g/L and is reddish in color and is used in agricultural machinery. Class C diesel is bluish in color, it is for domestic use

Difference Between Gasoline and DieselDifference Between Gasoline and Diesel

  • The types of gasoline are characterized by their octane rating, this is nothing more than the measure of anti-knock agents that gasoline has. Detonations and ensure the maximum release of energy in internal combustion engines.
  • Diesel oil, on the other hand, is differentiated according to its quality, type A is of higher quality, while type that is of lower quality.
  • Diesel oil releases up to 10% more energy than gasoline.
  • Diesel oil is made up of paraffin while gasoline is made up of a mixture of various hydrocarbons.

Diesel vs. gasoline: differences in its creation

Cars with a combustion engine today bear the greatest weight in the market, despite the change in trend that is opening more and more room for alternative technologies. Thus, there are many users who continue to weigh gasoline vs. diesel when buying a new utility vehicle. But what are the differences between gasoline and diesel? Is it the same fuel or do they have a different composition? diesel and gasoline

Oil and its derivatives

Pure oil contains different hydrocarbons, organic sulphides, nitrogen and oxygen compounds and small traces of metals such as iron, lead, sodium or nickel. Once extracted, refineries subject the crude oil to high temperatures (a process called fractional distillation) to separate the different components or raw materials.

The first fraction that evaporates is known as naphtha , made up of molecules that have five, six and seven carbons, and is used to make solvents . Next , the molecules that have between seven and eleven carbons are separated, which are the ones used to obtain gasoline . Subsequently , the components of kerosene and diesel are extracted , which have between twelve and fifteen carbons. Finally , lubricating oils are produced , for which a much higher boiling point must be reached.
