The automotive industries were dated back to the early 19th centuries, and it has prospered until right now in our communities. Most cars in the 19th century uses simple types of a combustion engine that laid the foundation for the development of the engine we see today. However, the fuel sources of both engines that are used to propel the cars remain the same (as long as they are used to powered an internal combustion engine). In today’s society, we mainly see cars that have a combustion engine uses pure gasoline. However, they are many types of gasoline from leaded to unleaded fuel and from octane ratings rated at 87, 89, and 91.
The invention of pure gasoline (not to be confused with Diesel) dated back to the Gilded age with the distillation of oil to kerosene. At first, there was no used for gasoline because cars were not invented and most transportation uses steam as its sources of energy. Therefore, it was discarded. Gasoline finally became a valuable commodity, with the introduction of Henry Ford’s affordable car in the 1920s known as the “Model T.” As time progresses, we saw an improvement in refining gasoline and creating a purer fuel that would make cars go faster. Increasing the purity of gasoline meant that the octane level must be increased, so lead was added to improve engine performance. The Octane rating tells us how much air and fuel mixture can be compressed before being ignited. The higher the octane, the more compression the fuel can withstand before detonating. However, leaded fuel was bad for the environment, so there was another development that leads to unleaded fuel.
Unleaded gasoline was introduced in the 1970s when health problems from lead increased. Unleaded gasoline also guaranteed the conditions of important engine parts like the intake valves and fuel injectors; that would help improve fuel economy and performance. In today’s gas filling stations, we will see that the stations are required to carry Unleaded benzene gas. The octane rating of the gas we commonly see is 87, 89, and 91. The most standard unleaded fuel are rated at 87 octanes. It was designed for most normal cars that doesn’t require much power, but it is still powerful for small cars on the road today. 89 octane stands in a higher tier than 87, but still could not compete with 91. It has a faster ignition capability that is suited for some small sports cars, like those made in Japan and America.
The King of the Hill that beats all consumer-grade fuel is 91. Octane 91 is the premium grade unleaded fuel that meet the demands of some of the today’s most advanced engines. It has an octane level of 93, but it is blended with an octane level of 91. We can see that the most demanding European cars and supercars are required to refuel with this type of fuel, in order to achieve full performance.
In conclusion, the automotive industry could not live without the use of gasoline that is distilled from crude oil. Even though the innovations of electric power have progressed far, it is still expensive for most people. Gasoline is still considered the primary fuel source for the automobile.
