Recently, the hottest topic in the circle of friends and major forums is the documentary film "Chai Jing smog investigation: under the dome" filmed by former CCTV reporter Chai Jing. As a car engineer who has lived in the devastated area for a long time, I think From the perspective of the car man, talk about cars and smog.
For the passenger car, Baidu Encyclopedia explains the passenger car. The passenger vehicle is mainly used for carrying passengers and their carry-on baggage or temporary items in their design and technical characteristics, including the driver's seat. No more than 9 seats. Passenger cars, including cars, minibuses and light passenger cars of no more than 9 seats, subdivided into basic passenger cars (sedans), multi-purpose vehicles (MPV), sports utility vehicles (SUVs) , dedicated passenger cars and crossover passenger cars. To put it bluntly is the private car we talk about everyday.
The name of the fifth part of Chai Jing’s video is: “Full-scale†fraud in the environmental protection facilities of diesel vehicles, but the author hereby specifically points out: 1. The diesel vehicles here do not include diesel passenger vehicles 2. Environmental protection facilities such as post-discharge treatment. Fraudulent behavior does not exist in passenger car companies.
First of all, let's talk about the number of diesel passenger cars. The market share of diesel passenger cars in China is very small. Taking 2013 as an example, the statistics released by Minghua Youdao Consulting Co., Ltd. show that in 2013, the sales volume of Chinese diesel passenger cars was 56,000, in the overall narrow passenger car. The market accounted for only 0.4%, down 0.2 percentage points from the previous year. According to the data from January to August 2014, the market share of domestic diesel passenger cars is only 0.5%.
In the Beijing market, the government has restricted diesel passenger cars early, so the growth of diesel passenger cars in the Beijing market has been basically zero in recent years. On the contrary, the data shows that the penetration rate of diesel passenger cars in the European market is more than 50%. In France, Belgium and other countries, the proportion is even more than 70%.
Second, we talked about the standard. At present, diesel passenger cars can basically be classified into light vehicles (maximum total mass does not exceed 3,500 kg), and light diesel passenger cars have begun to fully implement the national four standards. The national standard diesel fuel vehicle has greatly reduced the harm to the environment. At the same time, as mentioned above, the environmental protection facilities such as post-discharge treatment do not exist in passenger vehicle enterprises, so we believe that we are one of the few diesel passenger vehicles. Not the main source of smog.
Not to mention the petrol passenger car, North Shangguang has already implemented the national five standards, and the gasoline emissions of petrol cars are very small, but the petrol cars with huge reserves are often limited by major cities, serving as scapegoats for air pollution...
Which vehicles are contributing to the smog?
Chai Jing’s video also mentioned that PM 2.5 was high at night, which led to the “fake country four cars†that had been repeatedly exposed by the media. The author believes that "fake car four cars" (as shown in the video, most of the commercial vehicles transporting goods) is the car that contributes a lot to smog. Why is the "Fake Country Four Cars" rampant?
The state stipulates that a model can be mass-produced. It must first enter three lists: the Ministry of Industry and Information Technology, the “Vehicle Production Enterprise and Product Announcementâ€, the Ministry of Environmental Protection, the “National Motor Vehicle Emission Type Approval Catalogueâ€, and the AQSIQ “3C Certification Product Catalogueâ€. Therefore, before the car manufacturer mass-produces a model, it must first send the sample car to the designated testing organization of the country for testing. After passing the test prescribed by the national standard, it can enter the three lists and then produce.
The problem lies in the “test sample car†and the “production carâ€. There is a huge gap between the sample car sent by the enterprise and the car sold in the market. The sample car can reach the emission level of 'Guo Si' or even higher, but the mass production of the car is very different. Well, the problem is coming again. Why should the enterprise make fraud in production?
This problem is just as painful as overloading a large truck. If the big truck is not overloaded, basically the toll and fuel costs will consume all the hard-earned money of the driver. There is no profit at all, so it depends on the overload. Make money. Similarly, some original car manufacturers are faced with such a problem. If they do not make fakes or do not reduce the allocation, then the cost will not come down. If the cost does not come, they will not be able to compete with the products of other companies that are fraudulent or reduced. After all, car manufacturers also To make money, you have to eat, so you have to...
The right medicine for treating smog is here to talk about a few ideas for car pollution. 1. Oil product upgrade, even if the country's five cars use the oil of the country, then it will not be environmentally friendly, just like giving you a 4G mobile phone. But with 2G mobile phone cards, you still can't experience high-speed Internet access. Of course, oil upgrading will have a lot of resistance, and it will inevitably require reform of certain interest groups.
2. Strengthen supervision, the author proposes to supervise from two aspects. First, for the supervision of automobile manufacturers, the Ministry of Industry and Information Technology and the General Administration of Quality Supervision, Inspection and Quarantine should strengthen the supervision of the consistency of automobile manufacturers and ensure the test samples and production lines of all manufacturers. The production cars can be consistent and provide a platform for fair competition for all car manufacturers. At the same time, the traffic control department and the environmental protection department need to strengthen supervision and inspection in the on-line, annual inspection and on-road driving links to ensure the environmental protection of the vehicles in use.
3. Environmental protection is not just a matter of automobile manufacturers, oil, and petrochemicals. In fact, it requires all walks of life and everyone to support them. Therefore, Chai Jing’s video has played a positive role. After all, the whole society can pay attention to air quality.
