What are the differences between fuels?



What are the differences between fuels? Gasoline and Diesel are fuels made from petroleum, but there are several points between them.

When you refuel at the gas station, you have surely noticed the presence of many different fuels. Today, we can no longer find certain types such as “Super”, which has been banned for sale since 2000 because it contains lead which is harmful to the environment.

A brief overview of the other fuels on sale.

Fuels have different compositions

For gasoline, you should know that there are several types on the market: Lead Free 95 Where 98. This number represents its octane number: the higher the octane rate, the easier the ignition and the less wear on the engine. Certain service stations, in Switzerland or in Germany, even distribute SP100, a fuel more intended for efficient engines.

the Diesel, also called diesel, is produced from the distillation of crude oil. Compared to gasoline, its composition differs because gas oil comes from hydrocarbons heavier than those used to make gasoline. Diesel engines also function differently: ignition is carried out by compressing the air at very high pressure, which causes the fuel to rise in pressure and temperature. The combustion of diesel fuel thus allows the engine to run. On the gasoline side, the hydrocarbons used for its manufacture are lighter than those used for diesel. In gasoline engines, ignition is carried out by a spark plug, which ignites gasoline mixed with air.

L’gasoline E10 (or SP95-E10) contains up to 10% bioethanol, and thus contributes to the use of “cleaner” energy in vehicles. Superethanol E85 is composed of bioethanol up to 65% to 85%, and Lead Free 95 for the rest. This fuel is only compatible with specific engines called Flex Fuel, or cars equipped with an approved E85 converter box.
