Exhaust pollution is serious, and the development of exhaust detection is broad in the future.

automobile exhaust indeed refers to the exhaust gas emitted by motor vehicles or other equipment at work. In modern civilization, cars have become an indispensable means of transportation for mankind. However, with the rapid development of the automobile industry and the continuous increase of automobile production and ownership, automobiles have also brought air pollution, that is, automobile exhaust pollution

nowadays, with the development of China's economy and the progress of science and technology, people's quality of life has been improved in all aspects. The busy pace of life makes people buy private cars one after another. However, it is not only the increasingly serious traffic congestion and traffic safety problems, but also the problem of vehicle exhaust pollution, which seriously endangers people's physical and mental health

since entering the 21st century, for example, vehicle exhaust pollution has changed from a regional problem to a global problem. With the increase of the number of vehicles and the expansion of the scope of use, the harm of vehicle exhaust to the urban environment has become increasingly prominent. According to relevant data, at the beginning of the 21st century, automobile exhaust accounted for 30% of air pollution? 60%。 By the end of 2012, the total number of cars in the world had exceeded 1billion, which means that about one car for every seven people on the planet. The number of motor vehicles in China has also increased rapidly in recent years. By the end of January 2014, the number of motor vehicles in China had exceeded 2. 5% 500million vehicles, with drivers reaching 200million 900million people. Due to the good protection of our country's machinery, the main problems of the bullet train are large single vehicle pollution emissions, generally low vehicle fuel quality, and the lack of unified supervision by the government, vehicle exhaust seems to have become the main source of air pollution in China's cities

the main pollutants of motor vehicle exhaust are hydrocarbons, nitrogen oxides, carbon monoxide, sulfur dioxide, lead compounds, benzopyrene and solid particles. These pollutants have a great impact on human physical and mental health and the ecological environment. For the ecological environment, nitrogen oxides and other pollutants released by gasoline during the combustion process are the primary culprits of global warming; For human physical and mental health, long-term inhalation of pollutants emitted by motor vehicles will cause damage to human cells, reduce human immunity, and easily lead to breathing. When the dynamometer shows that the load is close to 50kN, the road and cardiovascular system diseases, and under specific conditions, the pollutants emitted by motor vehicles are very easy to be converted into carcinogens

at present, the control and treatment of automobile exhaust has become an important topic in the world. EU environmental protection experts believe that the effective way to reduce the harm of automobile pollution to the urban environment is to adjust the urban traffic policy, greatly reduce the number of private cars, give priority to the development of public transport, and promote bicycle traffic. At the same time, we should also accelerate the development and popularization of environmentally friendly vehicles and reduce our dependence on petrochemical fuels. Developed countries have made important progress and are moving towards ultra-low pollution and zero emission due to their advanced overall vehicle technology and vehicle exhaust control technology. However, China started late in this regard, and many control technologies are in the exploration and trial stage. Using relevant technical means to monitor vehicle exhaust can provide a lot of data and information for environmental pollution management, environmental science research, urban transportation and other fields. Therefore, at present, the country attaches great importance to vehicle exhaust detection

in accordance with the requirements of the law of the people's Republic of China on the prevention and control of air pollution, the standardization law and other policies and regulations, the competent environmental protection departments of the local people's governments at or above the county level can supervise and sample the emission of air pollutants from motor vehicles in use in the centralized parking and maintenance areas, without affecting normal traffic, Through remote sensing monitoring and other technical means, the air pollutant emission of motor vehicles driving on the road can be monitored and sampled, and the traffic management department of the public security organ shall cooperate. In recent years, most provinces and cities in China are actively carrying out sampling activities of vehicle environmental protection supervision

in order to control the problem of automobile exhaust pollution, China will continue to invest a lot of human, material and financial resources to strengthen the work of environmental governance. It can be predicted that the automobile exhaust gas detection market contains great opportunities and challenges, and enterprises in the exhaust gas detection industry will also usher in a better development scene and momentum. For instrument enterprises, continuous innovation and research and development of higher standards and better technology is an efficient way to win the market. Here, we also hope that instrument enterprises can shine brightly and contribute to China's motor vehicle exhaust detection work
