1. Introduction
Fuel Additive
at the time of the late 1970s and early 1980s, China had set off a car using additives climax. Then in ten years, the car industry there is a saying: engine refused to eat grains. The so-called “grains” mainly refers to the various fuel additives, oil prices in 2004, driven by the fuel additive consumption boom is heating up again.
additive selected good, it does not only serve to reduce fuel consumption efficiency, as well as maintenance of the engine, remove carbon deposits, environmental protection and other effects. Famous oil expert, former State Petroleum Product Quality Supervision and Inspection Center Deputy Director Xu Guoliang expressed fuel economy appear to be for the owners to save money, is actually a contribution to environmental protection.
In the fuel quality monitoring in developed countries in Europe, America, Japan and other aspects of emissions compliance and other management is very strict, in addition to follow the “World Fuel specification” standard, also proposed higher fuel standards. In these countries, the use of fuel additives are also very common, requirements are very high, its purpose is to effectively use the unique features of a variety of new fuel additives, so that the fuel does not produce glial become, coke and coke can be cleared at any time real clean fuel.
2. Category
Fuel additive is a very general statement, only one of the chemical additives, it can be divided into antiknock agents, metal deactivators depending on the role of anti- icers, anti-glue, antistatic agents, antiwear agents, flow improvers, smoke suppressants, oxidant, surfactants, bactericides and the like dozen. Wherein the portion of the additive through the carburetor clean or clear the nozzle, to improve the flowability of fuel oil to reduce waste; and wherein the oxidant additives such as a fuel is directly involved in the physical and chemical reactions of the engine cylinder, so that fuel combustion at the same time to complete, can effectively improve the efficiency of the engine. Therefore, the fuel additive or fuel can play a role.
3, four generations of products
famous oil expert, former Sinopec Research Institute of Petroleum Engineering and a professor Bi Chun carrying fuel additive into four generations.
The first generation, the main function for the carburetor deposits;
Second Generation function primarily for nozzle;
Third Generation main fuel injection mouth, the intake valve gumming, coking functions;
in addition to the fourth generation nozzle, a cleaning effect of the intake valve, the biggest improvement is the generation of inhibit coke combustor, decomposition.
four generations, a new generation is in keeping development on the older generation function, so logically speaking, currently available on the market should be the fourth generation of fuel additive fishes, but in fact they fuel additives market is four generations, what stuff there.
4, the brand
Relevant statistics show that China has all kinds of additives four hundred brands, of which pays top academics, good and bad mixed. However, the State Environmental Protection Administration identified and included in the national key environmental protection practical technology be promoted, only two brands, namely “Mega” brand and “state clean.” As a typical fourth generation, the former multi-effect of fuel additive products detergent is concerned, it is acting through the combustion chamber “microburst.”
5, the efficacy
Since the motor oil generally contain trace amounts of water, detergent and the water can be thoroughly dispersed refined form tens of thousands of small oil ( which is water), it rapidly expands boils “microburst” phenomenon at high temperature in the combustion chamber, i.e., the secondary atomization phenomena, so that the fuel mixture more uniform, and more complete combustion of gasoline, it is possible to save fuel, clear product carbon and reduce emissions.
the world’s largest chemical company, BASF had tests showed that the use of certain additives vehicles can reduce hydrocarbon emissions by 20% of the car,24% and 13% carbon monoxide, nitrogen oxides, a car can be made to reduce emissions of 1.1 tons in its life. Therefore, the rational use of fuel additives environmentally friendly.
6, the industry standard
“World Fuel specification” clearly against all metal additives, but many Chinese contain additives such as metal powders, causing damage to car parts.
China is currently no national standards or industry standards of fuel additives, the implementation of various enterprises are their own standards, only a few companies a high standard to the American standards of corporate standards, quality products can only be guaranteed.
7, add
traveling in the car when the 5000-10000 km, you can add a bottle. When adding, to add fuel additives, together with the gasoline, the fuel additive is such that the full roll, to prevent, remove the engine oil system in the gum or sediment.
purchase method
species currently on the market a wide range of fuel additives, nor a price, but it is always in the purchase of fuel additives must pay attention to the following:
1, whether the product has brand names, whether there is the bar code on the package, whether the product has quality certification of the national authorities, and if so whether the product is imported through formal channels.
2, whether the product is safe and reliable, after a lot of use of the product caused by acid corrosion, or metal residues will engine, but the car has caused tremendous damage, so be sure to choose to buy green non-corrosive residue-free brand.
3, whether the product has the effect of many additives on the market has exaggerated the effect of publicity, only a few cleaning function, the power aspect is not helpful, truly effective additive in the first box after use oil usually obvious sense, and not feel a little psychological change.
4, whether the product has a complete useTechnical support, whether with a strong after-sales force. Really tailored for your product is the best car, rest assured that there is a strong after-sales support to use.
8, buying advice
First of all there is to see whether the product quality certification authority of the State Department;
followed depends on the Enterprise whether through quality management system certification;
again to look for formal channels;
Finally, listen to the views of experts, and riders should also pay attention to more exchanges.
9, fuel-saving effect
gasoline prices, the owners appear before the power shortage in the car, after knocking problems before they buy additives to solve the problem, now it is mainly based on purchase saving considerations. But most consumers use after a few times, have gradually abandoned the use.
Although some owners do not value the effect of the additives, would not be spent in this area, but there is still a part of the owners’ bored. ” There are owners believe that long-term use of additives still have a role, help maintain the cleanliness of the fuel injectors, valves and so on.
Once the oil is not good, it is easy to cause the engine to produce coke, thereby affecting engine life. Regular use of additives, at least, is an early prevention, for car maintenance is concerned, there are still necessary.
choosing the right brand products, additives or useful, or else how would there be so many companies in the development, so many businesses in the sales. General knowledge and skills to add, rather than to listen to a gas station employees or dealers who are “recommendations”, is also necessary.
Experts suggest
Fuel additives can actually save much oil, how much power increase, is difficult to measure, consumers can not be blind to the manufacturer’s product data. In fact, and fuel consumption are closely related, is the condition, vehicle performance, driving skills. He believes that by additive fuel-efficient, save moneyUnrealistic, car owners usually pay attention to maintenance and repair, to develop good driving habits is the fuel-efficient fundamental way.
fuel tips
a low block start slow acceleration: a low-speed car start, gradually accelerated. Avoid large throttle, hard acceleration.
Second, light and slow foot stepped on the accelerator, the shift to fast grasp the opportunity: step on the accelerator pedal, it will result in “extra” oil, increase fuel consumption. Suddenly lift the throttle, the engine speed will suddenly decrease due to offset a portion of the traveling inertia, so that fuel consumption increases.
Third, the economic speed reducing fuel consumption: the city is often less than the economic speed, when road conditions were good and the speed is much higher than the economic speed, this is a multi-factor fuel. Economic speed vehicles are usually designed in the 70-90 km range, high-speed car with the most fuel stop at this rate, exceeds or falls below this speed driving, will bring varying degrees of increased fuel consumption.
Fourth, the more fuel-efficient driving straight: the car is more costly than straight oil when turning. Because of the increased resistance when turning, it will consume energy; subtraction block to pass through the curve, and each shift will be more consumption of fuel. So, if a straight line or curve will reach the destination, you should try to choose straight. If you must turn, we should relax before turning the throttle, the speed gradually reduced to a suitable and stable. In the corners to avoid foot brake, if the deceleration is also preferable to use engine braking.
Fifth, the gear speed to be correct: low-speed high-speed certainly fuel consumption, high-speed small oil is fuel-efficient. Now the car has provisions for shifting, engine speed reaches a predetermined speed block before they can add, exceeds a predetermined number of revolutions plus a lot of gear, it will cause fuel waste.
10, using the method
How to correctly use fuel additives?
for a long time to run the car must use, if reluctant continuous use can also be a month or every two weeks in a row with three or more, if the interval is too long with a slightly larger dose is recommended, really effective removal of the product carbon, improve fuel environment. The most economical way to use is the first time a continuous increase three times, which means that the new car in the first three plus tank of fuel when each addition ratio in accordance with the instructions on the purchase of additives.After the addition of three, run approximately 3000 km -5000 km (different road conditions and vary according oily), and then add three consecutive, repeated cycles of such suitable.
For cars, in the initial period, the engine oil additive system will gums or wash down deposits, will cause clogging of the filter hole and, at this time respond to a clean oil system maintenance, and continue to be used to add new vehicles manner, so that the purification effect is more ideal.
1:1000,1 addition ratio is generally additive may 50ml bottle with 50 liters of fuel; Furthermore, depending on condition should be added, depending on vehicle, the first vehicle good condition continuously for three bottles; condition decreased power
of the vehicle is less than the required continuously for more than 5 bottles until condition improves. Then add the selected compartment 1000 km or added once every one. If the engine is running well, as appropriate, may be used to reduce the ratio.
