Nanotechnology will become the core technology of automobile development in the new century. Reviewing the history of industrial revolution, it is not difficult to find that each industrial revolution is closely related to the development of basic disciplines. As early as 150 years ago, the first industrial revolution was triggered by the invention of the steam engine due to the fact that human beings accurately measured the size to millimeters; When human beings accurate the size to micrometers, it triggered the second industrial revolution represented by electrical equipment such as generators and motors. At the same time, it also led to the rapid development of chemical, automotive and other industries. When human beings make the size accurate to nanometer, it is possible to trigger a new industrial revolution again, especially in the automotive industry. When nanotechnology is widely used in automobile engine, materials, electronics, technology and other aspects, nano automobile is born

the concept of nanotechnology

"nano" is not only a unit of measurement of space and time, but also a unit of measurement of length, which is often popular in the latter. The conversion method is: 1 meter =109 nm, or 1 nanometer is 1 billionth of 1 meter. A human hair is about 70000 nm long in diameter. The term "nanotechnology" was originally extended from the word "nano", which refers to the technology for research and treatment of substances and materials with micro structures below 100 nm

at present, the application of nanotechnology is mainly reflected in two aspects: nano materials and nano devices. Nano materials such as nano carbon, nano copper, nano fiber, nano glass and other materials; Nano devices such as nano washing machine, nano tie, probe for scanning tunneling microscope, etc

nanotechnology is widely used in automotive materials

automotive parts are mainly composed of steel, iron, alloy, copper, glass, plastic and other materials. These materials can basically be made into nano materials by using nanotechnology. For example, China has recently successfully synthesized the world's longest "super fiber" carbon nanotube. Compared with steel, this kind of carbon nanotube is 1/6 the volume of steel with the same volume, but its strength is 10 times that of steel with the same volume. The birth of nano copper has added another "strange" property to the metal - superplasticity at room temperature. Its ductility is more than 50 times higher than that of ordinary copper. If these nano materials are widely used in automobiles, the future automobiles will be far superior to modern automobiles in terms of quality, strength, deflection and safety performance. Therefore, the traditional manufacturing process of "steel" automobiles will be changed

nanotechnology will make a qualitative leap in the engine

before that, ceramic engines were once favored by experts. In theory, the engine made of ceramic materials has many advantages, such as low friction, low heat loss, light weight, strong economy, etc. but so far, the ceramic engine has not entered the practical stage. If the engine produced by nanotechnology is adopted, it can not only overcome the weakness of traditional ceramics such as poor toughness and impact resistance, but also be widely used in key parts such as high temperature and vulnerable parts of the engine. Its structure and performance are far superior to those of ceramic engines, and it can also solve the contradiction of small engines and high power that manufacturers can not solve for a long time

application of nanotechnology in lubricants

not long ago, Qingdao tried a car care agent synthesized by nanotechnology on five large buses. After a series of strict tests, it was found that the fuel consumption of the five buses decreased from 15 L/100 km to 12.14 L/100 km, with a 19% decrease in fuel consumption. The average fuel savings of the five buses reached 16.2%, and the operating conditions were significantly improved, with a 50% oil savings. The biggest feature of this "nano lubricant" is that it is aimed at the metal surface, not the lubricant itself. Due to the mutual adsorption of these extremely small hydrocarbon molecules on the metal surface, these nanoparticles can completely fill the tiny pores on the metal surface, so that these thousands of small liquid balls can minimize the friction and wear between the metal and the metal pores. This new concept of single molecule nano lubrication technology will bring profound changes to the design of wear parts

application of nanotechnology in fuel oil

gasoline and diesel oil are widely used in vehicles at present. As two low-density sprayed foam thermal insulation products released by anjianeng company - anjianeng classic extreme series and anjianeng classic preferred series contain a small amount of sulfur, sulfur dioxide (SO2) gas will be generated during combustion when the engine is working. If an appropriate amount of nano additive is added to gasoline or diesel, it can form a very good catalyst in the process of developing a safe engine that does not cherish the machine. The sulfur content of the Fuel Catalyzed by the catalyst is far lower than the international standard (lower than 0.01%), and the combustion efficiency of the fuel is greatly improved. For example, Professor lizhengxiao from the Department of Technical Physics of Peking University has successfully developed a nano fuel additive by combining nanotechnology with advanced production technology. During the test, he added this additive to an appropriate amount of fuel, and found that this fuel additive can quickly diffuse into small spherical particles with a length of 6 nm in the fuel. Under the thermal motion energy, these small particles can obtain a thermal motion speed of more than 10 meters per second, so that the fuel can form a stable microemulsion under the action of Brownian motion. During combustion, the fuel can split into nano scale oil and gas particles, So as to achieve the effect of complete vaporization and full combustion

nanotechnology will make automobile tires colorful

at present, automobile tires are almost pure black. For people living in the vast world, a color seems somewhat monotonous. In the production of rubber, in order to improve the strength, aging resistance and wear resistance of tires, a certain proportion of carbon black is often added in the production process. If nanotechnology is used in the production of rubber tires, it can not only produce a variety of colored tires, but also improve the bending resistance of tire side rubber from 100000 times to 500000 times, and greatly improve the wear resistance and strength

nanotechnology improves automobile exhaust

nowadays, the increasingly serious problem of urban air pollution has attracted more and more attention, because it will directly threaten human survival. We know that there are two main sources of air pollution: factory chimney emissions (commonly known as fixed sources) and automobile exhaust (commonly known as mobile sources). In particular, automobile exhaust contains a large number of harmful gases such as sulfur dioxide, carbon monoxide and nitrogen oxides, and also belongs to "near ground emissions", which seriously pollutes human living space and respiratory layer. At the same time, it is easy to form an ozone layer, which has a great impact on human health, and it has to be treated. At present, EFI technology and three-way catalytic converter are commonly used to control automobile exhaust at home and abroad. If nanotechnology is used to control automobile exhaust, its oxidation-reduction capacity will far exceed the current technology. According to an automobile exhaust emission test report provided by the Chinese Academy of Environmental Sciences, after the three-way catalytic converter of the test vehicle was removed and the nano gasoline additive was added for 3500 km of operation, it was found that the pollution emission test results of the test vehicle under double idle operation were as follows: hydrocarbon emission decreased by 43.2%, nitrogen oxide emission decreased by 7.8%, and the pollution rate decreased significantly

outline sketch of future nano cars

future nano cars not only have bright colors in appearance, but also have superior performance and extensive design space, which are specifically reflected in the following aspects:

they are durable, safe and reliable with peeling off. Due to the extensive use of nano materials in cars, the hardness, deflection and seismic performance of future nano cars will be greatly improved, Its safety performance also increases, which makes it more durable, safe and reliable

the application of nanotechnology with small engine room and large riding space will easily reduce the size of the engine and related parts, make the engine, chassis and other devices more compact, and effectively increase the cab or riding space

the wide application of high-power and low emission nanotechnology in fuel and lubricating oil will greatly improve the energy-saving degree of future vehicles, which will make them more economical and popular, so that future vehicles can meet the requirements of high-power and low emission

in a word, nanotechnology can be applied from automobile body to wheel, covering almost all automobiles, making future nano automobiles more economical, comfortable, safe, reliable, powerful and colorful. If we say that our country's automobile industry has paid a huge price because it is in the millimeter and micron era and lags behind others, then today, when we stand on the same starting line of the nanometer era, people in the science and technology industry engaged in all fronts of the automobile industry point out that in recent years, the authors, engineers and entrepreneurs of waste plastic treatment and recycling should firmly grasp the opportunity of a thousand years, Join hands to seize the core technology of automobile industry development in the 21st century - nanotechnology
