A motor vehicle refers to a wheeled vehicle driven or towed by a power plant and running on the road for people to ride or transport articles and carry out special engineering operations.
The invention of motor vehicle is an important milestone in the history of human science and technology, which greatly promoted the progress of human civilization. According to statistics, at present, the number of all kinds of motor vehicles in the world exceeds 10 billion. As far as China is concerned.
With the development of China's socialist economy and the enhancement of national purchasing power, it has directly promoted the development of the automobile industry. Practically speaking, the emergence of motor vehicles directly expanded the scope of national activities, changed people's lives and improved people's quality of life.
However, it is undeniable that there are hundreds of millions of motor vehicles in China at present, and their total exhaust emissions have brought great pressure to the ecological environment. As we all know, the tail gas emitted by motor vehicles mainly contains solid suspended particles, carbon monoxide, nitrogen oxides, hydrocarbons, lead, black smoke and other harmful components.
These harmful substances not only seriously endanger people's physical and mental health, but also cause great damage to the environment. For example, the smog in big cities is a very serious example. As a responsible developing country, how to achieve environmental protection and emission reduction, and then control automobile exhaust emissions, is a very difficult problem.
There are many problems in the policy of vehicle exhaust treatment and control itself. The policies for the control and control of motor vehicle exhaust are gradually improving, and the relevant departments have unified regulations on different levels of exhaust control measures from an incomprehensible point of view, and have also issued certain policies, which have achieved certain results.
But on the whole, there are still obvious problems that can't keep up with the times, and there are also many problems in the policy of vehicle exhaust control and control itself.
For example, the existing legal policies are basically general, resulting in more abstract rights and responsibilities. Therefore, the responsibilities of various departments have not been clearly confirmed, and law enforcement departments are constrained by various principled provisions when implementing them, and law enforcement efforts are often not in place.
In addition, although the current laws and policies have made corresponding provisions on motor vehicle exhaust emissions, it can be said that the laws and regulations are still not perfect, because the treatment and control of motor vehicle exhaust needs a systematic treatment, and many elements are not really involved, such as public participation and exhaust pollution liability insurance.
