First of all, the condition of the new car is the best, and the fuel consumption and power performance are also the best in theory. Most of my friends are also maintained according to the normal process, and generally there will be no major problems. However, there are olefins, aromatics and so on in the gasoline of gasoline-burning cars. All gas stations have whatever gas they add. This thing can't be completely decomposed at high temperature, which is called "unclean combustion" in vernacular.
These "dirty" parts will form colloidal substances, which will accumulate thicker and thicker on the internal parts of the engine and gradually form carbon deposits. After driving for a long time, the carbon deposit will gradually increase, which will affect the working efficiency of the engine, make the fuel consumption of the car higher and higher, and the power will become worse and worse.
At this time, clean fuel can be used to remove carbon deposits. The main component of clean type is polymer surface active gasoline detergent. These compounds have the functions of peptizing, solubilizing and cleaning up carbon deposits, which can decompose stubborn carbon deposits and then be discharged after burning with gasoline at high temperature. So as to reduce the running burden of the engine and restore the fuel consumption and power of the car to the same working condition as that of a new car as much as possible.
In the journal of Equipment Manufacturing Technology, a paper "Discussion on new technologies and methods for carbon deposition treatment of automobile engines" was published. A comparative experiment of 1 vehicle 40 thousand kilometers before and after carbon deposition cleaning was carried out. The results show that after removing the carbon deposit, not only the components such as carbon monoxide, hydrocarbons and nitrogen oxides emitted by the engine are obviously reduced, but also the ignition of the automobile is smoother, the idling operation is more stable and the fuel combustion is more sufficient.
It can make the owner feel that the throttle seems to be lighter, or the power of stepping on the throttle is stronger. In addition, there are professional fuel-saving experiments and data, and a paper "Analysis of Cleaning Performance and Fuel-saving Effect of Gasoline Additives" was published in Automobile and Accessories. Among them, he used 1 car to carry out low-speed, medium-speed, high-speed and acceleration tests on high-speed and urban roads. The results show that the fuel consumption is reduced by 2%~4.5% after using fuel additives.
However, the actual use depends on the environment and driving style of the car. It doesn't mean that adding 1 bottle to fuel treasure will reduce the fuel consumption by 2%. Does adding 50 bottles directly reduce fuel consumption to zero? There is no such thing. This thing can make the car as young as possible, improve and restore its working condition, preferably not better than the new car, and it is a long-lasting process.
