CNG engine: replace traditional fuel and international trade researchlead the future power selection in traditional fuelWhile the machine is widely used, the exhaust emissions of vehicles also put great pressure on people's lives. In this regard, in order to reduce exhaust emissions, a new power option - CNG (compressed natural gas) has appeared on the market. It can not only reduce exhaust emissions, but also has the advantages of low cost and high efficiency, and has become one of the alternatives to traditional fuel engines. Compared with traditional fuel engines, the most prominent advantage of CNG engines is that they have a significant emission reduction effect. CNG engine fuel comes from compressed natural gas. Compared with traditional fuel, its sulfur content and particulate matter are very low, and it contains almost no flammable gases. Therefore, the content of harmful substances such as hydrocarbons, carbon monoxide, nitrogen oxides and particulate matter in the exhaust gas emitted is greatly reduced. According to international statistics, the CNG engine'sCompared with the emissible substances of traditional fuel engines, CNG engines may contain less than 1% of harmful substances, while traditional fuel engines are 100 times higher. Therefore, in terms of air quality and environmental protection, the CNG engine is a very important and powerful alternative. From the perspective of energy saving and emission reduction, CNG engines also have higher efficiency and cost advantages than traditional fuel. Compared with traditional fuels such as gasoline and diesel, the cost of CNG is obviously lower. CNG is a kind of elastic fuel. Its basic component is natural gas, which is cheaper than petroleum fuel. According to the global market price, the price of CNG is only about 1/3 to 1/4 of that of petroleum fuel. At the same time, CNG also has a good energy-saving effect, because it uses advanced combustion technology, which can make the energy utilization rate of the fuel as high as more than 40%.For car owners, the cost of using CNG is low, and the preferential government tax policy has also greatly reduced operating costs, and correspondingly, the transportation cost of enterprises will also be reduced. In addition, in large and medium-sized cities, traffic congestion is increasing, and electric vehicles and new energy vehicles have a long charging time and low efficiency, which cannot meet the needs of high-intensity use. However, CNG cars are not only easy to use and operate, but also support quick filling, which fully meets the characteristics of multiple uses in a short time. If the use of compressed natural gas vehicles is popularized, it will greatly reduce traffic congestion and improve environmental quality. In summary, the CNG engine has a very important application prospect. In order to accelerate the promotion and application of CNG, governments have taken positive measures to include CNG in the national development plan, continuously improve relevant regulations and standards, and support the promotion and application of CNG vehicles.In addition, preferential tax policies and the government's investment in new energy vehicles have supported the promotion and application of CNG cars. In the future, CNG engines will definitely become an important driving force form for small cars, commercial vehicles, public transportation and other markets, playing a positive role in environmental protection and solving traffic congestion. And in the development of CNG automobiles, more efficient and advanced technologies will continue to emerge, bringing greater improvements to future transportation.
