Benzene (in German: benzene) (Gasoline, gasoline) is a transparent and flammable substance derived from crude oil derivatives that is mostly used as fuel in spark ignition engines and internal combustion engines. Gasoline contains a group of organic substances Such as light hydrocarbons containing 4 to 12 carbon atoms. Hydrocarbons such as paraffins (alkanes), naphthenes (cycloalkanes) and olefins (alkenes) are present in gasoline, but octane (C8H18) can be considered one of the defining compounds in gasoline. Gasoline is a flammable and volatile solution of hydrocarbons derived from petroleum and used as a fuel for the internal combustion of engines.Gasoline is a by-product of petroleum products, and is a popular fuel for automobiles due to its high energy of combustion and the ability to combine with air in the carburetor.It is also used as a solvent for oils and fats. Gasoline is an energy-dense secondary fuel that is produced when crude oil breaks down into various petroleum products through the distillation process. In addition, some impurities are usually present in gasoline. Other substances, such as dyes, are also added Or oxygenated compounds such as ethanol, to gasoline for several reasons. Methods for detecting gasoline: Pale white When distinguishing between ordinary gasoline and supercars, you must first pay attention to its color, because The easiest solution. Regular car gasoline is pink and slightly reddish in color, but supercar gasoline is white and may even be green in some cases. Greasy and stinky Supercar gasoline is usually more volatile than regular gasoline, while conventional gasoline is not . The next solution, which is more familiar to drivers, and of course more difficult for novice drivers to determine; Pay attention to the difference between the gases emitted from the car's tank when refueling the car. At this point, you should notice that the gas coming out is dry, greasy, or smelly? If the exhaust gas is dry, then the gasoline used for the car is Super gasoline, but if the exhaust gas is greasy, the gasoline used is regular gasoline, and the fuel used is diesel. Mixed gasoline Also, if you think that mixing regular gasoline with super is wrong, you should It is said that this is very common and will not cause any problem, because if you do not have a suitable octane gasoline for your car, you can mix regular gasoline with super and you can reach the desired octane number. Gasoline octane number: What is Octane? Octane is a long-chain carbohydrate, the formula of octane is C₈H₁₈ and it has a very high crushing strength. ON evaluation is performed by two laboratory methods that require a standard engine. The standard engine required for testing may not always be available, especially in off-road sites or small or mobile laboratories. These and other considerations led to the search for a quick way to evaluate the impact of gasoline quality. These methods include FTIR (infrared spectrophotometry) and other methods. Extracting an equation that can be used to calculate octane quality has the same purpose with additional benefits. The octane index is often used to indicate the quality of octane. The octane index can be very useful in the composition of gasoline. Motor gasoline is usually a mixture of different types of refinery grades obtained from different processes. These grades are combined to determine the characteristics of the final product. Most refineries produce and market more than one grade of gasoline, the main difference being their shock-resistant quality. The ability to predict octane quality before blending is essential, and calculating the octane index can be important. Measure the octane number To evaluate this number, iso-octane and regular heptane are added to the fuel mixture and tested In the engine. In fact, the volume percentage of iso-octane in the mixture relative to heptane is the same as the octane number. For example, if gasoline contains 10% heptane and 90% iso-octane, its octane number is 90. High ONs will increase the fuel's resistance to compression and self-ignition. The methods for measuring ON are as follows: Research Octane Number The Research Octane Number (RON) is the most common method for estimating ON worldwide. This test is performed at an engine speed of 600 rpm with a variable compression ratio during the test to determine the anti-knock characteristic of the fuel. Higher ratios indicate more strokes. Motor Engine Octane Number The engine octane number (MON) is measured at 900 rpm. In this test, the fuel is first heated slightly to better determine the impact resistance of the fuel. Depending on the fuel composition used, this number is usually 8 to 12 units lower than ON. Anti-knock index (AKI) is the average between MON and RON is usually a number used at gas stations. Of course, European countries mostly use ON research to show gasoline octane. Road Octane Number The Road Octane Number (RdON) is estimated under real conditions. In this test, an engine with more than one cylinder in maximum throttle position is used. This method has been used since 1920. What is the octane number of Iranian gasoline? There are two types of gasoline, regular and super, in Iran. The octane number of regular gasoline is 87 and that of super gasoline is 95. Octane number of gasoline
