·The target is too much execution, the dispersion of new energy vehicles should focus on energy conservation and emission reduction

In recent years, the state's industrial policies supporting the development of new energy vehicles have been intensively introduced, which has led to the development of new energy vehicles carrying multiple missions, such as the realization of self-owned brand cornering overtaking, new economic growth points, energy conservation and emission reduction. However, the author believes that energy conservation and emission reduction are the most urgent tasks for promoting new energy vehicles.
Since 2012, a wide range of haze weather has caused widespread concern in society. According to data from the Ministry of Environmental Protection, in 2012, the total discharge of four pollutants from motor vehicles nationwide was 46.12 million tons. Among them, 39.17 million tons of carbon monoxide, 4.382 million tons of hydrocarbons, 6.4 million tons of nitrogen oxides, and 622,000 tons of particulate matter. Cars are a major contributor to total pollutant emissions, emitting more than 70% of carbon monoxide and hydrocarbons, and more than 90% of nitrogen oxides and particulate matter.
From the above picture, we can see that the PM2.5 value showed a downward trend on October 5 in the same weather, but PM2.5 showed a sharp increase in the peak of the return on the 6th and 7th. After the holiday The 8th and 9th working days are only slightly higher than the previous 2 days. It can be seen that the contribution rate of motor vehicles to PM2.5 pollution is much higher than people think. The massive emissions of motor vehicle exhausts pose a serious threat to human health while causing serious air pollution. The World Health Organization has elevated car exhaust to the “determined carcinogenic” level.
Recently, the "China's New Energy Vehicle Development Forum-2014 China New Energy Vehicle Development Forum" was held in Beijing by the People's Daily, the National Information Center, the State Council Development Research Center, senior industry experts and leaders of well-known car companies. Xu Changming, director of the Information Resource Development Department of the National Information Center, said that the current proportion of China's oil imports has reached 58%, and it is expected to exceed 70% by 2020. The annual increase of 20 million tons to 30 million tons of oil is mainly from imports. In 2020, China’s car ownership will reach 250 million, comparable to the United States. "If China does not get rid of dependence on oil imports as soon as possible, then this will become the biggest problem hindering the development of China's auto industry."
At the same time, in the government work reports of the two associations in recent years, "energy saving and emission reduction" has also been regarded as a breakthrough and an important starting point for transforming the mode of economic growth. On March 12, 2013, under the advice of the representatives and members of the National People's Congress, the State Council made 16 revisions to the government work report. Among them, the promotion of new energy vehicles was proposed in the area of ​​“strengthening and strengthening pollution prevention”. It is enough to see that “energy saving and emission reduction” is highly valued in the national high-level design.
At present, hybrid vehicles and pure electric vehicles have already occupied a certain market share and have received special attention from consumers. Hybrid vehicles are more acceptable to consumers than pure electric vehicles, both in terms of technology maturity and infrastructure. Zuo Shuguang, a professor at the New Energy Automotive Engineering Center of the School of Automotive Engineering, Tongji University, said that the emergence of hybrid engines has reduced pollutant emissions during fuel combustion. He also said that developers use a hybrid approach, which is expected to allow the engine to maintain the best combustion conditions while meeting the best power requirements of the car.
As of the end of December 2013, Toyota's hybrids saved approximately 18 billion liters of gasoline compared to gasoline engine vehicles of the same body size and equivalent performance, while reducing CO2 emissions by approximately 49 million tons. And because it does not require external charging, does not require battery replacement, and does not require additional maintenance and other features, is considered to be the most mature energy-saving technology.
In order to realize the era of true pure electric vehicles, a gradual and gradual process is needed, and it cannot be achieved overnight. Hybrid vehicles are an excessive platform from fuel vehicles to pure electric and fuel cell vehicles, and they are also necessary for China to achieve self-owned brand corners. According to the road, the author believes that if there is no preoccupation on the straight track before the curve to maintain the speed of survival, then the “curve” that is full of opportunities cannot achieve “overtaking”.
From the policy point of view, Xu Changming said that if the country's mission of promoting new energy vehicles is to achieve self-owned brand cornering overtaking, then it cannot support joint venture brands; if it is aimed at energy conservation and emission reduction, then whether it is domestically produced, Joint ventures or imported brands, as long as they can contribute to energy conservation and emission reduction, they should all enjoy corresponding policy support. It is not difficult to find that too many policy objectives will inevitably lead to decentralized execution and no homework. The author believes that the most effective way is to focus on the most urgent issues of the moment, in order to lay the most solid foundation for the further development of new energy vehicles in the future.

Titanium Dioxide(TIO2)

Titanium dioxide is an important inorganic chemical pigment, the main component is titanium dioxide. The production process of titanium dioxide has two process routes: sulfuric acid method and chloride method. It has important applications in coatings, inks, papermaking, plastics and rubber, chemical fiber, ceramics and other industries.
