There is also an National III car I bought at that time. I don’t drive much, and time goes by. Before I knew it, the vehicle exhaust emission standard has reached National VI . The annual inspection was last year. It is of course not a big problem to meet the National III standard. Recently, it has been reported that the National III vehicle will be included in the elimination scope, so I paid special attention to the actual inspection data. I wonder if this vehicle can meet the latest National VI standard ?
excerpted from the 2021 vehicle annual inspection report, the actual measured value of motor vehicle exhaust emission detection
went online to check the National VI standard, and found a standard on the official website of National Ministry of Ecology and Environment. I am not a professional and do not understand correction coefficient , so I will temporarily serve as a less accurate order of magnitude comparison.
excerpted from the Ministry of Ecology and Environment of the People's Republic of China, light vehicle pollutant emission limit and measurement method (China's sixth phase) https://www.mee.gov.cn
is not sure whether the HC of the detection project corresponds to the THC in the standard. In addition, the other two items can be compared. We transform them into the same units for convenient comparison:
Comparison of the measured value of exhaust emissions of National III vehicles and the limit value of National VI b
From the perspective of existing projects, the conclusion is that the measured value of this National III vehicle meets the strictest National VI b standard. Although there are some other exhaust emission testing projects in the National VI b standard, according to the existing measured data, even if the inspection is tested, the possibility of passing is still very high. What does
mean? As long as the vehicle is maintained regularly and only the specified oil is added, the quality of exhaust emissions is still very stable even after driving for more than ten years. I looked through the inspection data from previous years and found that the inspection value has become better and better with the increase in the service life of the car, especially from 2018 to 2019, the data has undergone a jumping improvement, and it has basically stabilized in the future.
cars are aging. The only obvious improvement in recent years is that our gasoline grade is constantly improving. Of course, this is not a strict scientific experiment. The instruments and equipment of different monitoring stations will also have allowable errors. However, for me, it cannot be ruled out that the doubt that the quality of oil products has a substantial effect on the emission of exhaust pollutants in automobiles is still very likely. What does
mean?
1) The actual measured exhaust emissions of National III vehicles may still meet the National VI b standard;
2) The improvement of oil quality may play an important role in exhaust emissions;
3) According to logical deduction, the actual measured values of National IV and National V vehicles are more likely to meet the National VI b standard;
0 discussing these seems to be a matter of erroneous, but it is not. We recommend the National VI standard for environmental protection. If the actual measured value of the National III vehicle complies with the National VI standard, should we also eliminate and scrap it with one size fits all? Is scrapping and dismantling a kind of pollution? Is it necessary to increase the consumption of resources and energy consumption when building a new car? Should I increase carbon emissions? Should we increase environmental pollution? Can students with primary school students not be able to take the entrance exam for Tsinghua University and Peking University? Even if you pass the grades, you can’t do it? Similarly, the scope of pollution elimination cannot be divided based on the vehicle production level, but the actual vehicle inspection data should be based on the basis of the vehicle; however, individuals purchase vehicles belong to personal property, and no one said that there was such use restrictions when buying them. Vehicles that are qualified from the factory are added with qualified oil and taxes paid according to law. Vehicles that can be used must be eliminated. Is it suspected of infringing on the right to use personal property? Some people may say that if you don’t eliminate old vehicles, how can you promote new car consumption and drive the economy? But I want to say, is such economic growth really meaningful? Is this growth of quality? Our society is so rich? Shouldn’t we save this part of the money and spend it on other more quality and meaningful consumption? If the actual test does not meet the National VI standard for qualified vehicles that meet the vehicle's factory exhaust emission standards, do they have to be eliminated forcibly? Can the cost of use be increased and market-oriented methods can be used to gradually discourage withdrawal, such as increasing the cost of and . This part of the money can be transferred to environmental governance or forced improvement of vehicle exhaust emissions, and try to avoid one-size-fits-all forced elimination?
Let’s talk about the matter and talk about environmental protection.The best use of everything is the greenest way of production and life, saving social wealth, cherishing valuable resources, reducing environmental pollution, and reducing carbon emissions. If a large number of vehicles that are old but meet the National VI standards are eliminated in a one-size-fits-all manner, it will not only damage personal property, but also lead to meaningless increase in unreasonable production capacity and carbon emissions, which is contrary to the goal of a green, low-carbon and intensive society we advocate. We hope that relevant departments will study it and introduce more reasonable plans.
*You may wish to pay attention to your vehicle exhaust test data to see if it complies with the National VI standard, or if this article has a wrong understanding of the standards, please point out and discuss it. *
