Gas octane is considered a ratio that is mixed with gasoline, and petroleum derivatives to obtain fuel with a certain efficiency. The higher the octane ratio, the higher the efficiency, and the speed of the engine. In addition to the octane number that determines the combustion resistance rate, each engine has a proportion that is proportional to it and does not cause damage Or lack of efficiency, and through today's article, we will learn about octane gasoline, the types of gasoline, and the suitability of each type of engine.
Definition octane number
The octane number, or octane rating, is a measure of the performance of an engine or flying fuel. The higher the number of octanes, the higher the pressure of the fuel that helps to ignite.
It is preferable to use fuels that have a high percentage of octane in high-performance gasoline engines
as they require higher pressure since there are fuels that have a low percentage of octane.
The high percentage is represented in the numbers of Citane, as this type of fuel is proportional to diesel engines, as these engines compress the air, not pressure the fuel, which is called the ignition pressure engines, so we have to use the appropriate fuel for the engine so that the engine is not hit and damaged.
Gasoline octane 100
The octane increases the resistance of gasoline, the higher the percentage inside gasoline, the more resistant the gasoline mixture, the more efficient the engine, and gives it high performance, there are three degrees of octane: octane 87 (normal quality), octane 89 (average quality), and octane 93 (excellent quality) ).
Therefore, octane 100 gasoline is petrol intended for aircraft for its superior quality as the octane works to provide gasoline with the lead that prevents the engine from stalling in the case of aromatic hydrocarbons and alcohol, but the lead at this time was the preferred and appropriate choice as it helps to reduce the cost of production as gasoline was Lead supplied is the type of fuel prevailing in the United States of America in 1921 AD as a suitable type to protect the environment from pollution.
Petrol harm 100 octane
But with the development of time and the passage of time, the health hazards caused by this fuel have been proven, so it started disposing of it, eliminating it, and not using it gradually until it was completely banned, so studies and experiments have proven that lead has toxic damages, chronic diseases in addition to its negative effects on children, causing them to develop poverty Blood, IQ, impaired learning plus nerve damage.
Octane measuring device
There is a set of easy-to-use devices that specialize in measuring the octane ratio, knowing its value, and its suitability for the operation of the car's engine. Also, the octane ratio is displayed with numbers shown on petrol pumps, and it is written in black on a yellow background.
How to raise octane gasoline
There is a specific solution that can be used to raise the octane of gasoline, and its type is chosen according to the type of gasoline used for the engine, and also the engine's compression ratio, the compression ratio is the one through which the type of gasoline appropriate for the car is determined.
If you use the appropriate gasoline for the car, the solution does not affect performance, and there is no point in using it, but if the gasoline is less than what the car engine needs, and it does not fit with it, the use of solutions effectively affects torque and performance.
Ethanol has a huge ability to raise the percentage of octane inside gasoline, and it is mixed with gasoline to increase the rate of octane, as this mixture is made in all countries to obtain a better fuel type, especially for modern cars.
In conclusion, we recommend that you use the appropriate type of fuel to operate your car engine with high efficiency, and distinctive quality. Using the wrong or poor type will damage the engine control systems, low efficiency, and torque over time.
The octane rate measures the ability of the fuel to strike, the resistance during combustion resulting from the fuel mixture, and the air that is blown into the engine. The higher the octane ratio in the fuel, the more you find that your car is running better, and this requires an increase in cost.
Petrol 91 and 95 and its relationship to octane
Some people do not realize the difference between petrol 91 and petrol 95, but each type has a set of features that distinguish it from others, and it is determined according to the specifications of the engine of the car, when you drive the car you can determine the appropriate type for it, by:
- If the torque of the car changes and becomes less than normal, this is evidence of a lack of octane, and the engine needs a higher ratio.
- If the car was parked, then I started it and pressed the gasoline, and the engine made a loud bang sound. This is evidence of a lack of octane.
- Or if you are going slowly, then you increase the speed suddenly, then a cracking engine sound comes out, which means that the octane ratio is low.
- If you want to turn off the car after returning from your drive, and it does not turn off quickly, this is evidence of a lack of octane in the engine.
If one of these situations occurs with you without a specific malfunction occurring in the car that requires it, it is better that you use octane 95 gasoline for the engine, as this is the appropriate quality for it so that it is not damaged or damaged.
Types of gasoline
The types of gasoline are classified according to the percentage of octane, and the number inside it. The octane is the main factor in the ability of gasoline to explode, the higher the percentage, the greater the resistance. Among the types of gasoline:
Gasoline 80
This gasoline is suitable for cars that are powered by old engines, and it is distinguished for its lower price compared to the following types, but it is cautioned to use it for modern cars, this is inconsistent with the instructions specified by the manufacturer, as the engine is subjected to damage in a short time in addition to the car consuming a greater amount of gasoline with no getting Efficiency, speed required.
Gasoline 92
It is one of the petroleum derivatives, and it is the most used in the market. Most modern cars are supplied with this type of gasoline because it has properties that make it maintain the integrity of the engine in addition to providing efficiency and desired speed with low consumption, but also if your car engine is supplied with gasoline 95 You cannot use 92 gasoline with it so as not to damage the engine, and its efficiency will dwindle.
Gasoline 95
It is considered one of the best and purest types of gasoline and petroleum derivatives. It is used to supply supercars, and the most important thing that distinguishes it is its suitability for all types of cars. Owners of old cars for its use, and the use of petrol 80, and 92 for modern cars due to the high price of it is the most expensive of these types.
