At present, chemical additives are mainly used in the market. Because chemical additives are mixtures with complex components, the components of fuel additives from different manufacturers are completely incomparable. Some components already exist in fuel, and some components have completely different effects on oil products of different fuel manufacturers and different vehicles. Adding them to some oil products really plays a very good role. However, instead of playing a role, the chemical reaction precipitated due to the addition of fuel additives, blocking the oil circuit and causing flameout and flameout. Classification of fuel additives From the production process of additives, fuel additives can be divided into chemical additives, biological additives and physical additives.
1.？ chemical additive
Chemical additives are the earliest additives, which add chemical substances to fuel and achieve certain effects through chemical reactions. Such as antiknock agent, metal passivator, antioxidant, anti-icing agent, anti-sticking agent, antistatic agent, antiwear agent, anti-ablation agent, flow improver, corrosion inhibitor, smoke suppressant, combustion improver, cetane number improver, cleaning dispersant, heat stabilizer, dye, surfactant, bactericide, lubricant, etc. , which is added in the production process of oil production enterprises. At present, the old process chemical additives on the market are mainly the combination of these substances, or have been strengthened in some aspects.
After adding chemical additives to oil products, it is necessary to know through experiments whether precipitation and delamination occur when they interact with other additives. Therefore, chemical additives must be tested to determine their stability before use after adding fuel. Oil production enterprises can add chemical additives with definite effect. For end users, the cost of stability test after adding is too high.
2.？ Biological additive
Biological additives are a kind of additives produced by biosynthesis in recent years. Biological additives have the following advantages: (1) It takes plants as raw materials and meets the requirements of sustainable development; (2) The amount of CO2 absorbed during the growth of plants is equivalent to that released during the use of bio-based additives, which can alleviate the greenhouse effect; (3) Natural substances are easily degraded by microorganisms, which can reduce environmental pollution; (4) Lipid groups in plants are polar, and plant preparations have a moderating effect on hydrocarbons and alcohols and a combustion-supporting effect on fuels. For example, palm oil is used as raw material to prepare a bio-based gasoline abroad, and we use ethanol as bio-based ethanol gasoline in China.
abuse
The bio-based fuel additive can obviously improve the fuel economy of the engine, and the modified bio-additive can increase the octane number of gasoline by 65438 0.5 units. Because the quality control of biological additives in the process of biosynthesis is very difficult, the quality of each batch of products varies greatly, and the function decays quickly, and it will lose its function in a short time. Therefore, the reason why bio-based additives can improve gasoline combustion and are selective to fuel needs further study. Therefore, at present, bio-based fuels such as ethanol fuel in China not only vary greatly from batch to batch, but also deteriorate after being stored for a short time, which affects the working efficiency of mainstream engines such as direct injection engines. In severe cases, it will lead to engine idling jitter, ignition difficulty, early combustion and fire.
3.？ Physical additive
In recent years, the physical additives mainly studied by American super technology have attracted the attention of the industry. According to the characteristics of local fuel, this additive uses some chemicals to improve the characteristics of fuel through physical action. The specific working principle is as follows: the production process of nuclear magnetic vibration transmission agent is to select high-quality naphtha as the matrix for transmitting nuclear magnetic vibration and make it enter a special nuclear magnetic vibration generator. In this device, naphtha can obtain nuclear magnetic resonance characteristics, and make it permanently remember and preserve its vibration characteristics. Naphtha with vibration characteristics is used as "mother liquor" (stock solution). When in use, a part of the dosage is added into additives to melt the additives into liquid fuels (gasoline, diesel, heavy oil, kerosene, light hydrocarbons, alcohols, ethers, etc.). ) and gaseous fuels (liquefied gas, natural gas, etc.). ), so that the vibration characteristics of this "mother liquor" can be transferred to. The fuel with this vibration characteristic explodes synchronously in the engine at high temperature and high pressure, and the combustion is extremely full, thus achieving the effects of reducing exhaust emissions, increasing power, saving fuel and noise, and removing carbon deposits. It's also easier to get started. In addition, vibration waves can crush and expel stones in the human body without causing harm, just like ultrasound in the medical field. With the help of efficient chemicals, Brownian motion principle and flocculent decomposition technology, the old carbon deposits in the internal combustion engine of the engine are strongly discharged. The decomposed carbon deposits are much smaller than the pore size of the three-way catalyst and can be discharged from the exhaust pipe smoothly. And the service life of the engine is prolonged (the effect of removing carbon deposits without disassembling the cylinder is achieved). This "mother liquor" (stock solution) with nuclear magnetic vibration characteristics is called "nuclear magnetic vibration transfer agent" and is now an additive of general stock solution. How to identify good additives
abuse
This kind of nuclear magnetic resonance naphtha has high production cost and high technical threshold, and has not been used on a large scale at present. Only a few fuel additive manufacturers use it, and the technology needs to be authorized to use it, and the authorization period is long.
superiority
Because the matrix of nuclear magnetic vibration transfer agent is naphtha, the proportion of naphtha to fuel tank is calculated. The naphtha added in a small amount not only has good miscibility with fuel oil, but also has no chemical reaction with existing chemicals in fuel oil, and only has physical vibration transfer effect with fuel oil. The mechanism of action is different and does not affect each other, which completely overcomes many disadvantages of repeatedly adding chemical additives to fuel oil.
Domestic fuel additives can't meet the industry standards.
Internationally, refineries usually provide performance evaluation index data of brand fuels, because it is not enough to pass the component index only. Performance evaluation is an important part of measuring fuel quality. China's fuel performance evaluation standard is still blank. Composition indicators are not strictly enforced. Due to the lack of evaluation standards and methods for fuels in China, the local technical supervision bureau cannot implement monitoring. The international industry has strict requirements on the performance index of fuel oil. For grade 2 unleaded gasoline, there are four points: first, the cleanliness of the fuel nozzle requires that the maximum flow loss should not exceed 5%; Second, the intake valve is stuck and requires to pass; Third, the cleanliness of the intake valve should not exceed100 mg on average; Each valve; Fourthly, the deposit in the combustion chamber should not exceed 140%.
Therefore, we will find that the adaptability of imported cars and joint venture engines to domestic fuel is very poor, which is also related to the lack of specific fuel evaluation standards, because these engine technologies are developed according to foreign fuel standards, but the foreign standards are far higher than the domestic fuel standards, because the idling jitter of direct injection engines has become a long routine at this stage.
Due to the lack of strict standards for domestic composition indicators, the use of a large number of inferior chemical additives has also caused many adverse consequences. The main components in many inferior chemical additives are themselves limiting components in fuel, such as lead, manganese, iron, silicon, benzene, diluted hydrocarbons, sulfur and phosphorus. Excessive addition of these substances. It destroys the quality of crude oil, and many chemical additives are much more toxic than reference oil. Chemical additives react with fuel, which improves the performance in some aspects. However, the addition of benzene-containing substances may also produce many other chemicals, such as phenylpropyl pyrene, which is a highly carcinogenic substance with great toxicity. Another example is tetraethyl lead, which is one of the additives in gasoline and diesel oil and is a highly toxic substance. After use, it caused secondary pollution, and now it is out of the field of fuel additives. The addition of iron-containing substances affects the function of vehicle electromagnetic valve and reduces the performance of the whole vehicle.
At the same time, we should pay enough attention to imported additives. The research and development fuel composition standard of imported additives is completely the fuel of exporting countries, which can't adapt to the domestic fuel field. It can be said that it can't basically meet the domestic fuel composition requirements, but at the same time, consumers have to pay high tariff costs, which is not worth the candle. When choosing additives, it is best to choose the sixth generation additives which have physical properties and are completely suitable for household fuel. If you really can't choose it, the easiest way is to ask if the additive mother liquor is Siyoupu (stock solution) mother liquor.
How to choose a good additive, how to avoid detours, is the fuel additive useful, and how to choose it so as not to be taken into the pit?
With the continuous improvement of engine production technology, fuel quality needs to be improved simultaneously to adapt to the changes of advanced engine technology. If only the improvement of engine technology and the improvement of fuel quality stop, it will lead to the mismatch between engine and fuel, and various phenomena will appear in engine operation, such as premature combustion, idling jitter and weak acceleration. Ma Yun said, "If the bank does not change, I will change the bank." . Then, without the improvement of fuel technology, fuel additives will help to improve fuel quality, improve the use of automobiles and maintain automobiles more scientifically. At present, advanced fuel additive products are also keeping up with the pace of engine technology upgrading, and related technologies are becoming more and more mature.
? Nowadays, fuel additive technology has entered the 6.0 era. However, due to the benefits and new technical barriers, most manufacturers are still using relatively backward old technology to provide oil circuit maintenance products for car owners. According to the statistics of the National Academy of Sciences, among every 10 fuel additive manufacturers, 9.5 are still using the additives with the technology of National Five or below. These "outdated" technologies are really helpful for low-end emission standards. However, since entering the era of direct injection engine and the national six-row low-carbon emission requirements, this technology has been unable to adapt to the new engine and the latest environmental protection technology requirements. Words that once vowed to defend the blue sky have become more and more skinny in the face of reality. In fact, it is very simple to identify whether it is the latest technology additive, and it can be identified simply by whether it is a general stock solution cleaner. Let's see how many misunderstandings there are about the use of fuel additives. Understand and be familiar with the misunderstanding, and you will naturally know the correct and scientific answer.
To sum up, there are the following misunderstandings and status quo in the market. Let's get to know them together.
Misunderstanding and current situation 1:
We only use old-fashioned additives and think that old-fashioned additives are more reliable. In fact, the technology of old-fashioned additives still stays at the old technical level because of market inertia. We should know that Tesla was introduced to learn advanced car-making technology, and also to encourage domestic car companies to work hard for the horsefly effect. The more old-fashioned products, the more comfortable they are in the current technology, and the technology does not pursue innovation, which simply cannot meet the changing requirements of automobile engine technology, let alone the original use.
Misunderstanding and status quo II:
Some car owners are superstitious about pure imported additive stock solution. In fact, there are as many as 12 kinds of automotive fuel additives in the world. So most consumers will be confused. Strictly speaking, as long as it is mixed with fuel, it can be collectively called stock solution. It's not the pea that people often say. Amines, such as PIBA, are reserve liquids, but they only belong to one of more than a dozen reserve liquids.
As the largest country in automobile and petrochemical technology, the United States is also far ahead in fuel additive technology. In the large-scale use of shale oil in the United States, a considerable proportion of fuel additives have been mixed into refined oil before entering the gas station, but they can be seen everywhere on the shelves of large, medium and small supermarkets. The display of various additives suitable for American fuel is very common in the United States. What must be said here is that the imported fuel additives are formulated according to the fuel of the importing country. The fuel in the importing country is very different from the domestic fuel, and the composition and quality of the basic crude oil are very different, so the composition of the distillate oil is naturally huge. In addition, the technology of domestic fuel is different from that of foreign countries, so the matching degree between imported fuel additives and domestic fuel is a big question mark.
In 2008, after China issued the detailed rules for the separate sales of fuel and fuel additives, the fuel after 2008 can be understood as "naked oil" without additives. Therefore, we have seen the emergence of small bottles of additives in gas stations. This is completely different from what many people understand, that is, "the fuel quality is good, why should we sell additives separately?" This phenomenon comes entirely from the introduction of rules, and it is precisely because of such rules that the price of fuel per liter has never exceeded that of 9 yuan.
What are the characteristics of the sixth generation fuel additive? Based on American technology, the additive specially developed for China fuel market is called the sixth generation fuel additive. It is the best additive in China at present. The core component is the additive of Siyoupu stock solution. This additive is multifunctional integration, and the premise of research and development is based on the characteristics of household fuel, so it has such a halo and reputation.
Misunderstanding and status quo 3:
Many car owners still feel that additives are useless. According to statistics, among the interviewed 100 car owners, 60% think that additives are useless, and among these 60%, 98% car owners use EFI and naturally aspirated engines. In other words, although 58% of car owners have no influence on fuel additives, it is because they all use the old technology engine-EFI naturally aspirated car. The remaining 42% car owners think the additives are useful, and they all use engines with the latest technology of direct injection turbocharging.
Therefore, in today's world where direct injection vehicles become mainstream engines, don't listen to the opinions of EFI naturally aspirated car owners easily, because if the maintenance is not timely, the ultimate loss will be borne by yourself. The EFI naturally aspirated engine does not need fuel additives, but it feels different because of different combustion methods. In fact, just like people getting sick, feeling good now doesn't mean there are no potential lesions. When the lesion broke out, there was nothing to be done. It has become an inevitable way to disassemble the engine for maintenance. Just like a person undergoing surgery, disassembling the engine will inevitably damage the integrity of the engine and the sealing performance of the factory, and other related problems are immeasurable. Therefore, daily use of fuel additives for vehicle maintenance is obviously necessary.
Misunderstanding and Status Quo 4:
Quite a few car owners and many repair shops think that new cars don't need additives. In fact, from the moment the car leaves the factory, it has a lifelong marriage with fuel. Just like us humans, we eat inferior cooking oil seasoning and spoiled rice noodles every day. In the long run, the probability of getting sick will increase, which will seriously affect our life span and quality of life. We need to get all kinds of vaccines when we are young, instead of treating them when we grow up sick. The same is true of cars. When manufacturing a new car or a quasi-new car, it is necessary to prevent various car maintenance problems caused by oil lines. Don't wait until it's really not enough to carry out overhaul. You know, after COVID-19 is cured, his lungs will become fibrous stroma, and his performance will plummet after the car is overhauled. The man-hour fee for vehicle maintenance is enough to use the additive of RMB 100 each time, once every 5,000 kilometers, and drive continuously for 400W kilometers. You know, few drivers can travel more than 100W km in their lifetime. In order to save a little money, I finally lost a lot of cost, which was not worth the loss.
Then the repair shop is professional. Don't you know this truth? You know, most people still have no concept of additives and don't know what fuel additives are. In addition, a large number of low-quality and inefficient additives flooded the market, making bad money drive out good money. People often don't know what a good additive is, let alone buy a good fuel additive for their cars. The repair shop also has interests to consider. It is better to spend some time and want to clean the oil circuit manually. You know, no one wants to clean the oil circuit manually, and the working time is less than 1500 yuan, not counting the material use cost. Consume a lot of time, energy and cost. There is no difference between the results and effects of using efficient fuel additives. Aside from the opportunity cost, the economic cost is only a fraction of the previous one.
Misunderstanding and status quo 5:
Choose cheap additives. We should know that the low price of additives only meets the needs of consumers to reduce the purchase risk, but it also comes with many disadvantages. Any product has a cost, and low-cost additives are easy to cause various sudden symptoms of vehicles. Even if there are no sudden symptoms, if you choose an ineffective additive, the money spent is equal to white flowers. In this way, the cost is actually higher. The import tariff problem leads to the high price of imported additives. Although the price of this kind of additive is high, its use value is hard to say, because the price of this kind of additive abroad is less than one-third of the domestic market price, so we can make our own reasoning on the quality. Therefore, don't be superstitious about imported additives. On the one hand, we should consider whether it is suitable for domestic fuel, on the other hand, we should consider whether consumers should pay tariffs on such additives.
Misunderstanding and status quo 6:
Superstition about original additives. In fact, car companies are industrial manufacturing enterprises and have no chemical technology and foundation. The original additives are all produced by OEM. If some consumers just like the fuel additive of the original automobile brand, then they can ask if it is the additive of the original stock solution. If not, then there is a question mark on performance.
Misunderstanding and status quo 7:
Superstition about the safety of fuel 100% in big gas stations. In fact, no matter what gas station it is, it is necessary to clean the filter elements of the fuel tank and refueling equipment regularly. There is a filter screen on the refueling gun, which is cleaned once a month. If it's not dirty, then why clean it? Oil storage tanks should be cleaned regularly. If there is no impurity, colloid and moisture, why should it be cleaned? After the vehicle transporting fuel is introduced into the underground oil storage tank, the fuel should be stabilized for 30 minutes, and refueling is not allowed. If there are no oxide impurities in the fuel tank, why should the oil be stabilized for 30 minutes and not allowed to refuel? Its biggest purpose is to prevent too many impurities from being added to the car and causing problems. But now because of the interest problem, the operation of stabilizing oil for 30 minutes is almost rare. So there is no 100% fuel quality, and there is no 100% fuel without quality problems.
Any fuel has a deterioration cycle, and ethanol and Liu Guo fuel deteriorate very quickly. It takes 2-3 days for the fuel company to leave the factory, 2-3 days for the fuel company to reconcile, 2-3 days for the fuel company to transport it to the gas station, and 2-3 days for the gas station to add it to the car. The whole cycle is 9- 12 days. If you run very little after joining the car, for example, you run out in 20 days, and the whole time is one month, then the fuel of ethanol country 6 began to deteriorate in 7- 10, which actually started long ago. It's like we humans have been eating bad food, and high concentration of nitrite will inevitably have a direct impact on the canceration of the body. If vehicles use deteriorated fuel for a long time, it will inevitably cause problems such as engine jitter, weakness, high fuel consumption and serious engine oil overhaul.
All the opinions that there is absolutely no quality problem in the added fuel are based on the premise of not denying self-knowledge, but does not overthrow yourself mean that you have no thinking logic? Like stealing a clock. Therefore, the idle jitter of many new cars can not be detected, and there is no fault code, which is often attributed to the fuel problem in the store. However, the owner of the car still stays in the thinking level of believing that the fuel 100% of the big gas station is fine, and resolutely denies the fuel problem, so many disputes will occur.
Misunderstanding and Status Quo VIII
It is considered that fuel additives can only remove carbon deposits. Removing carbon deposits from fuel additives is indeed one of the functions. However, a good fuel additive can do more. Because the oil circuit was initially filled with colloid and impurities. Water appears gradually, and the design of gasoline filter can help us prove this. Carbon deposition is only the product left after fuel combustion. The fundamental reason for this phenomenon is that the participation of oil, bacteria, colloid impurities and water in the fuel circuit leads to excessive carbon deposition. Therefore, a good fuel additive must be able to remove carbon deposit, remove water and decompose colloid, and corrosion and rust prevention are indispensable.
At present, in the field of fuel additives, in addition to using fuel additives lower than the national standard 6, merchants are also blindly pursuing the effect of promoting clean carbon deposition, but the additives developed in this way can not cure the symptoms. What's more, most additives have no effect on removing carbon deposits. Another misunderstanding to be strengthened here is to blindly emphasize the removal of carbon deposits, that is, to use strong alkaline additives. Long-term use will lead to the aging of the nozzle sealing ring and damage other parts of the engine. Because the neutral additive that does not hurt the car is a safe additive that can be used continuously. At present, the additives of this stock solution on the market are all Sioupu stock solution, which is more protective for automobile maintenance.
Misunderstanding and status quo 9:
Blindly believe in brands that have been made for a long time. In fact, China Post is a brand that can be traced back hundreds of years. However, after the opening of the express delivery industry, which one is better and more efficient than the postal service? Therefore, blindly believing in big brands, it is better to consider whether the brand products are updated in time, whether they meet the current market demand, and whether they can really solve market problems. In this regard, we can see from the sub-field of fuel additives that the products made by Siyoupu fuel additive generate, whose technology originated from the United States, focus on studying the fuel market and demand in China, and are more suitable for China car owners.
Misunderstanding and current situation 10:
Blindly believe that the additives of big companies are the best. In fact, product research and development pays attention to concentration and singleness. Apple used to have hundreds of single items, but later it was compressed into several single items, which created the monopoly position of Apple's mobile phone. Nokia produces more than a dozen mobile phones every year, and the result is defeated by Apple. Therefore, a company specializing in one category is a unique good company in this industry, and its products naturally represent the most advanced technology and quality.
Misunderstanding and the present situation eleven:
Direct injection and EFI engines use different additives. No matter what type of engine uses the same fuel, fuel additives, as the name implies, are to manage the fuel circuit. Therefore, there is no fuel additive for direct injection engine and EFI engine alone, and there is no special fuel for direct injection engine in the market. Naturally, there is no fuel additive specially used for direct injection engines.
To sum up, our China car owners should have basic recognition ability when choosing fuel additives. The above eleven o'clock is just the tip of the iceberg, and it will continue to be added in the future. I hope that the majority of car owners will take fewer detours and choose high-quality car maintenance products that can really solve vehicle problems. CCTV tests are easy to add.
? Can fuel additives save fuel? From 1980s to early 1990s, there was an upsurge in the use of automobile additives in China. With the rise of oil price in 2004, the consumption of fuel additives rose again. Many car owners have encountered such a problem when refueling at gas stations: Do you want to add some additives to your car to help you save fuel? ......
Last year, the oil price was high, and some car owners achieved the goal of saving fuel by making fuel additives, and also maintained the engine and oil circuit. Car owners who benefit from additives will definitely not agree with Zhang Xu. They will say that all the shortcomings are not the fault of additives, but that you have not used additives correctly. Can fuel additives really save fuel? Fuel additive is a very general term. As far as chemical additives are concerned, they can be divided into more than ten kinds according to different functions, such as antiknock agent, metal passivator, anti-icing agent, anti-sticking agent, antistatic agent, antiwear agent, flow improver, smoke suppressant, combustion improver, surfactant, bactericide and so on. Some of these additives can improve fuel fluidity and reduce fuel waste by cleaning carburetor or dredging fuel nozzle. Among them, additives such as combustion improver directly participate in the physical and chemical reaction of fuel in the engine cylinder, so that the combustion of fuel can be completed at the same time, which can effectively improve the efficiency of the engine. Therefore, fuel additives can still save fuel. A test report issued by market authorities once pointed out that the qualified additives produced by regular manufacturers in the market can generally save oil by 10% to 15%. If the choice is good, it can not only reduce fuel consumption, but also increase power, maintain the engine and remove carbon deposits. In addition, the analysis of environmental monitoring data shows that hydrocarbons in automobile exhaust decreased by 26.6% and carbon monoxide decreased by 65,438 0.97% after using correct fuel additives. Because the quality of fuel is very important to fuel consumption, exhaust emission and power performance.
At present, there is still a big gap between the quality of fuel produced in China and that in the world, so adding some additives to fuel can better meet the requirements of fuel economy, emission and power, and achieve the role of environmental protection and energy saving. How to use additives With the development of petrochemical industry, some additives with the function of cleaning carburetor and nozzle have been added in the production of some refined oil products, and the owners usually do not need to buy and use them.
At present, most of the chemical additives on the market are the combination of several functional substances, which only strengthen some functions. In terms of fuel additive products in China, there is only a non-mandatory standard formulated by 1999, and there is no unified industry standard. Fuel additive itself is a good industry that benefits the country and the people, but the problem of "poor dispersion" in the market is more prominent. According to our reporter's knowledge, there are more than 400 brands of additives in China, including mud and sand. The main components in some chemical additives are themselves limiting components in fuel, such as lead, manganese, iron, silicon, olefins, sulfur and phosphorus. Excessive addition of these substances will destroy the quality of raw fuel, while additives containing sulfur and phosphating substances may produce strong carcinogens at the same time, which will be discharged with tail gas to form highly toxic emissions. Chen Chaoming, head of the workshop department of Audi Automobile Company, is an expert in the field of automobile maintenance. According to him, most of the genuine additives currently on the market are harmless to the car itself, and the key is the effect. The use of chemical additives needs special attention. Due to the variety and complexity of chemical additives, some chemical reactions between additives will have adverse effects, so don't use more than two additives at the same time before you know the composition and chemical characteristics of the additives used.
In addition, due to the different oil components of different fuel brands, the interaction with fuel additives is also different. Even if additives are added to a brand's oil products, it may cause negative effects such as precipitation, oil blockage, increased flameout times, decreased power and increased fuel consumption. Therefore, before using chemical additives, we should not only consult the experienced car owners about the additives themselves, but also understand the brands and types of fuels that are "tacit" with them. In addition to chemical additives, a new generation of physical fuel additives also appeared in the market. For example, Siyoupu fuel additive, which uses nuclear magnetic resonance technology for naphtha stock solution, is a new generation of multi-purpose additive produced by the latest technology of the sixth generation. According to the bench test data of the manufacturer, the dynamic performance of the additive is improved by 28%, the average fuel consumption is as high as 2O%, and the automobile exhaust emission can be reduced by 80%. Price is another important issue that car owners care about. Because there are many brands and varieties, the prices are also quite different-take the imported gasoline additive with specifications of 354 ml as an example, the price ranges from 100 yuan to 300 yuan, and the usage ratio also ranges from 40 liters to 100 liters of gasoline. From the point of view of saving fuel and money, if the fuel-saving effect of additives is 10%, the average "break-even point" of additives spread on each liter of gasoline is 0.65 yuan, which is equivalent to the ratio of a bottle of additives to 70 liters of gasoline. If 92 # gasoline (6.5 yuan per liter) is used, then the "break-even point" for saving fuel and money with additives is 0.59 yuan per liter of gasoline. Of course, if the additive is a combination of physical stock solution and chemical additive, and it has the functions of cleaning fuel injectors and carburetors, removing water in oil circuits, and removing corroded and rusted colloid, its price will be higher, because the technical cost of this additive is high, the technical barrier of mixing and matching liquid medicines is high, and a lot of fillers are used in the middle, which is naturally much higher than that of ordinary chemical additives.
Fuel expert's purchase reference
1.？ Usually, additives with physical properties will not change the composition of fuel, so they will not be corrosive to automobile engines. 2. Read the description of additives carefully. Do not use additives containing metal particles. Because the additive containing metal particles is added to the automobile using the three-way catalytic converter, it may produce adverse reactions, which may lead to the failure of the three-way catalytic converter in serious cases. 3. See if the product has gone through formal channels and whether there is a qualified test report from a national authority. In particular, pay more attention to imported products. According to China's current laws and regulations, all imported products must have a national statutory inspection report, and the bottle body trademark description must be displayed in Chinese with self-adhesive stickers, otherwise it may not be sold, in case someone fishes in troubled waters, fakes imported products with fake and inferior products, and harms consumers. Beware of the price trap. Because the additive market is not yet mature, consumers don't know much about the price, and some businesses deliberately set ultra-low prices. Anyway, consumers will not be heartbroken if they use it cheaply, and they are not afraid of being cheated. 5. Advise consumers to choose brands with advanced domestic technology. Because the gap between domestic and foreign products in additive technology is not obvious at present, just like the color TV industry, the actual effect of some domestic products has surpassed that of similar foreign products, and the prices are much more affordable.
Choosing fuel additives is not necessarily good for high prices, nor for foreign products. Most importantly, the research and development path of foreign fuel additives is foreign fuel, and most of them are not suitable for the characteristics of China fuel. If you want to choose the fuel additive under the current fuel emission standard, it is best to choose the additive of National Standard 6, Sipu stock solution. The additive of this stock solution not only meets the national standard 6, but also meets the national standard 45. The most important thing is that the imported American technology is specially developed based on China fuel. Moreover, it uses nuclear magnetic vibration naphtha stock solution, which is a physical additive, neutral and does not hurt the car. Dehydration, carbon deposition, glue removal, corrosion protection and rust prevention are all available. If you see this additive, you can use it with confidence.
