At present, the automobile on the market is more and more widely used for small-displacement turbocharged engines, and many car manufacturers have deliberately introduced some models equipped with small-displacement turbocharged engines in the domestic market. Why do they do this?

The first is to reduce the cost of car purchases. As small-displacement supercharged engines are the compromise between economy and power, coupled with the state's preferential policies for small-displacement vehicles, more and more buyers are beginning to favor the purchase of small-displacement cars. The horsepower of the car is small, but for a family car, horsepower is sufficient. Another point is that the amount of tax on the use of vehicles and boats is also linked to the vehicle's displacement, and the vehicle's consumption tax levied on the same standard as the vehicle and boat use tax. It is for these reasons that we have seen more and more small-displacement cars appear in our lives.

Followed by environmental protection, because the vehicle exhaust contains hydrocarbons, nitrogen oxides, carbon monoxide, sulfur dioxide, lead compounds, benzopyrene and solid particulate matter. Not only does it cause photochemical smog, it is also one of the sources of haze. The smaller the car's displacement, the less pollutants it emits. Therefore, considering the economical and environmental aspects, small-capacity turbocharged engines are becoming more and more popular.

Finally, because of the increasingly fierce competition in the auto market, the price competition among autos is inevitable, while the small-displacement model has an advantage in price. Whether it is the position of a consumer or the position of a business, the function of a car can be sufficient, and it does not require blind pursuit. Instead of spending money where it isn't necessary, it's better to use the money to improve the car's configuration.

The formation of fluoride crystal mica is a sub-grade, and does not adsorb impurities. It was selected by the Chinese Academy of Sciences Environmental Biology Research Center Peking University, Tsinghua University, Shanghai Fudan University, Nanjing University, and more than 100 national research institutions and universities for Afm Substrate After (microscopy carrier wave), the relevant person said: Compared to natural mica, fluorite mica has better flatness and less adsorption impurities. The images observed in the analysis of the DNA structure, especially in the 1 nm to 100 nm scale, have observed surface interference fringes not found in the natural mica experiment, which are clearly dozens of times better than the natural mica Substrate. Experts involved in the experiment believe that the use of fluoride mica instead of natural mica as a substrate material is expected to catch up with the international level.
