A few days ago, the State Administration for Market Regulation announced the national supervision and random inspection of vehicle gasoline cleaner, which is commonly known as "fuel treasure": 105 batches of products were randomly inspected in 12 provinces, and 42 batches of products were unqualified, with a failure rate of 40%.
When many car owners go to refuel, they will be sold fuel treasures; In some e-commerce live broadcasts and short **, the effect of automobile fuel treasure has been praised to the sky: a bottle of fuel treasure can easily remove carbon deposits, improve power, and even have the effect of saving gasoline and reducing exhaust emissions while driving.
What kind of "treasure" is fuel treasure?

The survey found that there are two types of fuel treasures currently sold on the market:
A fuel treasure that can increase the octane number of gasoline and improve the thermal efficiency of the engine, also known as Fuel TreasurePower-type fuel treasure
Another type of fuel pro is designed to clean deposits that accumulate in the engine, combustion chamber, fuel injection system, etc., and it contains specific components that can clean or take away the deposits, hence the nameClean Fuel Booster
Zhang Xiang, a researcher at the Automotive Industry Innovation Research Center of North China University of TechnologyIn an interview with China News Service, he said that the core function of Fuel Treasure is to remove sediment in the fuel system of automobiles, that is, carbon deposits. Carbon deposits can lead to increased friction between engine components and affect the efficiency of the engine system, so removing carbon deposits is essential to keep the engine running efficiently.
In Zhang Xiang's view, the core substances of clean fuel treasure are polyetheramine and polyisobutenemine, which do have the effect of removing carbon deposits.
As for the power fuel treasure, Zhang Xiang believes that although it can increase the octane number, the use of this fuel treasure itself may also lead to carbon deposits. The best solution is to buy high-octane gasoline instead of relying on extra fuel. At present, the best solution is to choose to add high-grade gasoline at the gas station. All things considered, this octane-increasing fuel booster is not recommended because it can cause damage to the engine.
However, he also pointed out that the actual use of some fuel treasures is suspected of being exaggerated, and there is a certain difference between the magic effect advertised in advertisements and the mouths of refuelers.
Zhang Xiang explained that since the fuel treasure is mixed in the gasoline, only the location where the gasoline can reach can exert the cleaning effect. Theoretically, it cannot be cleaned where gasoline cannot reach, such as the throttle and the back of the intake valve of a direct-injection engine.
Zuo Jianyao, the founder of Beijing Nuoche Studio and an automotive aftermarket practitioner with 13 years of experienceIn an interview with China News Service, it was introduced that the clean fuel treasure does have the effect of cleaning up carbon deposits. However, it does not increase the vehicle's power limit, and its main function is to optimize the fuel combustion process and improve the efficiency and performance of the engine.
According to expert analysis, most ordinary family cars do not need fuel treasure, and the carbon deposits of the engine can also be removed through daily driving behavior to ensure the normal operation of the engine.
Zuo Jianyao believes that the new car does not need to add fuel treasure, only regular maintenance. Old cars can use fuel treasure moderately, it is recommended to add it every 5000 kilometers, and it should not be too frequent. If the engine of the old car is in good condition and has less carbon deposit, there is also no need to use fuel treasure. With the improvement of the cleanliness of gasoline, gasoline itself has a cleaning effect, and it is enough to clean up the carbon deposits by driving at high speeds.
Zhang Xiang further gave examples, for example, moderately running the engine at high speeds, or driving on the highway for a period of time, which can accelerate the internal circulation of the engine and make the combustion more intense, which will help to burn off the carbon deposits and achieve the effect of removal.
In some special cases, it may be more reasonable to use Fuel Booster. For example, vehicles that drive at low speeds, traffic jams, extreme cold or hot weather for long periods of time are more likely to generate carbon deposits. Therefore, whether you need to use fuel treasure, you should make an appropriate choice according to the vehicle use environment and driving habits.
A few days ago, the State Administration for Market Regulation announced the national supervision and random inspection of the quality of automotive gasoline detergent products in the circulation field. Focus on the pour point, flash point (closed), sulfur content, chlorine content, rust resistance, corrosion degree, demulsification, simulated intake valve sediment quality and other 7 items for inspection, of which the flash point (closed) item is a safety item.
Officials said that among the 105 batches of products sampled in this random inspection, 42 batches of products were unqualified, with a failure rate of 40%. Among the 42 batches of unqualified products, 22 batches of products were unqualified for chlorine content, 19 batches of products were unqualified for simulated inlet valve sediment quality items, and 15 batches of products were unqualified for flash point (closed) items.
In this sampling, according to the requirements of the national standard, the inspectors tested the base gasoline with different fuel treasures under the specified conditions, and the difference in carbon deposition adsorbed on the sediment collector was very obvious.
Liu Cixiang, engineer of the Petrochemical Institute of Shandong Provincial Product Quality Inspection and Research InstituteIt is said that the test results fully show that the unqualified "fuel treasure" of the simulated intake valve sediment quality project not only fails to achieve the effect of removing carbon deposits, but may aggravate the generation of carbon deposits in the automobile fuel system.
According to public information, there are about 500 "fuel treasure" production enterprises in China, of which more than 90% are small and micro enterprises, mainly distributed in Guangdong, Beijing, Tianjin, Hebei, Shandong and other places. There are significant differences between different fuel treasures**.
How to buy Fuel Booster? In Zhang Xiang's view, special attention should be paid to the spot check of fuel treasure products by the State Administration for Market Regulation, so as to avoid buying fuel treasure products that are announced by the State Administration for Market Regulation as unqualified brands. In addition, it is advisable to choose products from large brands, as these brands usually have stricter standards for quality control and provide more reliable products.
In addition, consumers should also pay attention to the composition of Fuel Treasure. "Consumers should pay attention to the concentration of core ingredients in Fuel Treasure, such as in the product ingredient introductionThe concentration of polyetheramine should be maintained above 30%.to ensure that the product has an effective cleaning effect. Zhang Xiang said.
