Gasoline, also known as gas or petrol is a mixture of volatile, flammable liquid hydrocarbons derived from petroleum and used as fuel for internal-combustion engines. Gasoline hydrocarbons range around 250 °C and consists mainly of three groups: gasoline with a boiling point range of 385 °C or even –C14 to 25C between 20 54 and a maximum drop point of 0°C of paraffinic, naphthenic and aromatic with a minimum ignition point of 820.
Petroleum gas consists mainly of three groups - with a boiling point range of 385 C and even 25 C14-C between 20-54 and a maximum drop point of zero °C of paraffinic, naphthenic and aromatic, and has a minimum ignition point of -820.

 The most important aspect regarding gasoline is it’s number which is 15.6kg/m 860 equals to 3°C. it is worth noting that this product’s cetan number requires to be more than 50 in order for the engine to work smoothly and soundless. A measurement criterion for gasoline’s fuel combustion delay time regarding diesel engines, is the “cetane number”. he higher the number, the better the fuel burns within the engine of a vehicle. ... In other words, it is how minimized the delay is between when the fuel is injected into the chamber and when the combustion begins. Generally, diesel engines operate well with a CN from 48 to 50. Fuels with lower cetane number have longer ignition delays, requiring more time for the fuel combustion process to be completed. Hence, higher speed diesel engines operate more effectively with higher cetane number fuels. The minimum cetane number for gasoline must be 50.

Practical usage of gasoline

Light:

Gasoline is a type of lighting device that uses kerosene as a fuel; such as oil lamps, they are useful for lighting without electricity, such as in regions without rural electrification, in electrified areas during power outages, at campsites, and on boats.

Fuel:

It is widely used as a fuel in aviation as well as households. Kerosene is commonly used to power jet engines of aircraft (jet fuel) and some rocket engines and is also commonly used as a cooking and lighting fuel.

The country's industrial diesel is mainly obtained by mixing gasoline products from atmospheric distillation, vacuum distillation, isomox oil, kerosene distillation in the atmosphere and naphtha mixture with different percentages in the country's refineries to improve the quality of fuel combustion in diesel engines and Reducing environmental pollutants should reduce the amount of sulfur, nitrogenous compounds and aromatics, density, boiling point and residual carbon.
