【Basic Knowledge Activity】Professional “Basic Knowledge” in the petrochemical industry: What is the anti-knock property of gasoline?
Thread Content
What is the knock resistance of gasoline? When engine fuel burns in the cylinders, violent vibrations, knocking sounds, and a decrease in power output occur; this phenomenon is known as knocking. The property that measures whether a fuel is prone to detonation is called knock resistance. If detonation does not occur easily, the fuel is considered to have good anti-knock properties. Explosion resistance is one of the important indicators for engine fuel. ============================================= 【Petrochemical Section】Compilation of professional “basic knowledge” posts (Supported by the main forum; surprises await, and great prizes are up for grabs) http://bbs.hcbbs.com/thread-1557057-1-1.html (Source: Haichuan Petrochemical Forum). This initiative encourages various sections to organize the publication of basic knowledge posts, or for individuals to do so on their own (the content can be gathered from the Internet or created originally; participation can take place through multiple topics, with no restrictions on the approach used – it could be an explanation of a noun or an introduction to a series of principles). What are some suggestions and methods for getting in touch with cleaners? The regular administrator will reward the content that performs well. You will also be rewarded for regions where the activities are more intensive. (Regions should also conduct summarization and optimization based on the amount of such content available in their area.) ———————————————— The second phase of the event runs from February 20, 2016, to the end of June 2016; at least 50 award vouchers are available for you to claim (mugs, power banks, USB drives, and other prizes or event benefits). Awards can be given at any time based on performance, and additional rewards can also be granted at any time depending on performance. (12,000 activity points and rewards await the regions that perform well)
Explosion resistance refers to the ability of gasoline to resist knocking during combustion in an engine; it is a key indicator of gasoline’s combustion performance
The anti-knock property of gasoline refers to its ability to resist knocking during combustion in the engine cylinders, and it is evaluated using the octane number. The Xinwan value is a conventional figure used to indicate the anti-knock property of fuels for spark-ignition engines; it is the ratio of the actual anti-knock property of gasoline to that of standard gasoline.
The anti-knock property of gasoline refers to its ability to prevent detonation during combustion in an engine, and it is a key performance indicator of gasoline. A high blast resistance allows the use of engines with a higher compression ratio, which in turn increases the engine’s power, reduces fuel consumption, and improves its efficiency. The anti-knock property is indicated by the octane rating; the higher the octane rating, the better the anti-knock performance of the gasoline. The octane rating of gasoline is indicated by its number, such as 70, 80, 85. Currently, domestic cars should use fuel with an octane rating of 85 or higher (MON), while many imported luxury cars require lead-free gasoline with an octane rating of 93 or 97 (RON). To improve the anti-knock properties of gasoline, tetraethyl lead is generally added to it. Since tetraethyl lead is toxic, gasoline containing it is often dyed red as a marker to prevent misuse and poisoning by users.
