The principle of fuel additives to save fuel is mainly cleaning. For details, please see the analysis below
In the 1980s and early 1990s. Our country has once set off an upsurge in the use of automotive additives. As oil prices rose in 2004, fuel additive consumption heated up again. Many car owners have encountered this question when refueling at a gas station: Do you need some additives for your car to help you save fuel...Can fuel additives really save fuel?
City On the central arterial road, Zhang Xu drove his Mitsubishi Pajero slowly along with the traffic during rush hour. Suddenly, a Honda drove past dragging black smoke. "Honda is just like that." Zhang Xu was laughing in his heart. His girlfriend sitting in the passenger seat sighed: "It can't be a mechanical failure, it's a new model." "...Maybe it's the same as you did last time, there's something wrong with the oil!" His girlfriend's words reminded Zhang Xu of the time he used fuel additives a year ago. The Pajero SUV he bought consumed a lot of fuel, so he listened to his friend's advice and bought a certain brand of fuel additive in order to reduce gasoline expenses. Unexpectedly, it backfired - not only did he lose fuel, but his power dropped, and he was almost fined because the exhaust was black smoke. After he stopped using the fuel additive, all the adverse reactions disappeared - and he never mentioned it again. It’s about using additives.
When oil prices were high last year, some car owners achieved fuel saving by using fuel additives, and also maintained their engines and oil lines. Car owners who have benefited from additives will definitely not agree with Zhang Xu. They will say that all shortcomings are not the fault of the additives, but that you did not use them correctly. Can fuel additives really save fuel? Fuel additives are a very general term. Just looking at the chemical additives, they can be divided into anti-knock agents, metal passivators, anti-icing agents, anti-gluing agents, and anti-knock agents according to different functions. There are more than a dozen types of electrostatic agents, anti-wear agents, flow improvers, smoke suppressants, combustion accelerants, surfactants, bactericides, etc. Some of these additives reduce the waste of fuel by cleaning the carburetor or unclogging the fuel injector and improving the fluidity of the fuel; while additives such as combustion accelerants directly participate in the physical and chemical reactions of the fuel in the engine cylinder, making the fuel burn. Completed at the same time, the efficiency of the engine can be effectively improved. Therefore, fuel additives can still play a role in saving fuel. A market authoritative department once issued a test report stating that qualified additives produced by regular manufacturers on the market can generally save 10% to 15% of fuel. If you choose it well, it can not only reduce fuel consumption, but also increase power, maintain the engine, and remove carbon deposits. In addition, analysis of environmental monitoring data showed that after using the correct fuel additives, hydrocarbons in vehicle exhaust dropped by 26.6% and carbon monoxide dropped by 197%. Because the quality of fuel is crucial to fuel consumption, exhaust emissions, and power performance.
The quality of the fuel produced in China is still very different from that in the world. Therefore, adding some additives to the fuel can better meet the requirements of fuel economy, emissions, and power, and achieve environmental protection and energy saving. role. How to use additives With the development of the petrochemical industry, some additives that can clean carburetors and fuel injectors have been added in the production of some refined oils, and usually do not require car owners to purchase additional additives for use.
Most of the chemical additives currently on the market are combinations of several functional substances, which only strengthen the effects of certain aspects. In terms of fuel additive products, my country has only one non-mandatory standard formulated in 1999 and lacks unified industry standards. Fuel additives themselves are a good industry that benefits the country and the people, but the problem of "scattered and poor quality" in the market is quite prominent. As far as our reporter has learned, there are more than 400 brands of additives in my country, of which there is a mix of good and bad. The main ingredients in some chemical additives are themselves restricted ingredients in fuel, such as lead, manganese, iron, silicon, olefins, sulfur, phosphorus, etc.
Excessive addition of these substances will destroy the quality of the original fuel, and additives containing sulfur and phosphorus substances may simultaneously generate strong carcinogens and be emitted with the exhaust, forming highly toxic emissions.
Chen Chaoming, director of the workshop department of Audi Automobile Company, is an expert in the field of automobile maintenance. According to his understanding, most of the genuine additives currently sold on the market do no damage to the car itself. The key is the effect. . The use of chemical additives requires extra care. Due to the wide variety and complex composition of chemical additives, chemical reactions between some additives can produce adverse effects. Therefore, do not use more than two additives at the same time before knowing the composition and chemical properties of the additives used.
In addition, since different fuel brands have different oil compositions and have different interactions with fuel additives, even if an additive is added to a certain brand of oil, it does play a very good role. However, switching to another gas station to use fuel produced by another company may also cause negative effects such as sedimentation, oil line blockage, increased stalling times, reduced power, and increased fuel consumption. Therefore, before using chemical additives, you must not only consult experienced car owners about the additive itself, but also know the fuel brands and types that "cooperate well" with it. In addition to chemical additives, a new generation of physical fuel additives is also emerging on the market.
For example, Siyoupu fuel additives that use nuclear magnetic resonance technology to produce naphtha stock solution are a new generation of multi-purpose additives produced with the latest sixth-generation technology. According to the manufacturer's bench test data for this additive, the power performance is improved by 28%, the average fuel saving is 20%, and the vehicle exhaust emissions can be reduced by 80%. Price is another important issue that car owners are concerned about. Due to the wide variety of brands and varieties, the prices also vary greatly - taking the imported gasoline additive with a specification of 354 ml as an example, the price ranges from 100 yuan to 300 yuan, and the usage ratio also varies from 40 liters to 100 liters of gasoline. From the perspective of saving fuel and money, assuming that additives achieve a fuel-saving effect of 10% and 98 No. gasoline is 7.3 yuan per liter, the "profit and loss point" of the additives spread equally to each liter of gasoline is 0.65 yuan, which is equivalent to 0.65 yuan. A bottle of additives has a usage ratio of 70 liters of gasoline; if No. 92 gasoline (6.5 yuan per liter) is used, the "profit and loss point" for additives to save fuel and money is 0.59 yuan per liter of gasoline. Of course, if the additive is a combination of physical liquid and chemical additives, and has the effect of cleaning the fuel injector and carburetor, removing water from the oil line, and removing colloid, anti-corrosion and anti-rust effects, the price will be higher because The cost of this type of technology is relatively high and the technical barriers to mixing and matching of medicinal solutions are relatively high. There are more fillers used in the process, which is naturally much more expensive than ordinary chemical additives. Fuel expert's purchasing reference
1. Generally, additives with physical properties do not change the composition of the fuel, so they will not be corrosive to the car engine.
2. Read the additive instructions carefully. Do not use additives containing metal particles. Because additives containing metal particles may have adverse reactions when added to cars using three-way catalytic converters, and in severe cases may cause the three-way catalytic converter to fail.
3. Check whether the product has passed through formal channels and whether there is a test report from a national authority. Pay special attention to imported products. According to the current laws and regulations in my country, all imported products must have a national statutory test report, and the trademark description on the bottle must be on a self-adhesive sticker showing the Chinese description, otherwise it shall not be sold to prevent someone from fishing in troubled waters and using fake and inferior products. Imported products harm consumers.
4. Beware of price traps. Since the additive market is not yet mature, consumers do not know much about prices. Some merchants deliberately set ultra-low prices, giving consumers the illusion that they are not worried about being cheated because they are cheap.
5. It is recommended that consumers choose domestic brands with advanced technology. Because the current additive technology gap between domestic and foreign products is not obvious, just like the color TV industry, the actual effects of some domestic products have surpassed similar foreign products, and the prices are much more affordable.
The choice of fuel additives does not necessarily mean higher prices or foreign products.
The most important thing is that foreign fuel additives are developed based on foreign fuels, and most of them are not suitable for the characteristics of Chinese fuels. If you want to choose fuel additives under the current fuel emission standards, it is best to choose Siyoupu raw liquid additives that meet the National VI standards. The additives of this kind of stock solution not only comply with the National VI standards but are also applicable to the National IV and V standards. The most important thing is that the imported American technology is specially developed according to Chinese fuel. Moreover, it uses nuclear magnetic resonance naphtha stock solution, which is a physical additive and is neutral and will not damage the car. It is equipped with water removal, carbon deposit removal, glue removal and anti-corrosion and anti-rust properties. If you see this type of additive in the stock solution, you can use it with confidence.
In addition, we need to remind everyone that excellent fuel additives can at most restore the fuel consumption and power of the car. It is impossible to exceed the original factory's fuel consumption and power, otherwise automotive engineers will be laid off.
