During the National "two sessions," the deputies of the National People's Congress and the chairman of Yuchai Group's board of directors Yu Ping brought with them thoughtful and thoughtful proposals. Luan Ping believes that: "Medium- and heavy-duty commercial vehicles with a capacity of over 3.5 tons should be used as a vehicle exhaust emission control and de-emphasis. It is recommended that the state subsidizes medium and heavy-duty vehicles that meet the national IV emission standards."
Junping proposed that the plan contains two layers of meaning: the maintenance of medium- and heavy-duty vehicles is not large, but the highest proportion of pollutant emissions is in automobiles; the existing related policies lack balance. The current government's relevant policies are mainly to encourage new energy vehicles. Development, but for the commercial vehicles that should be the focus of emission control, guidance policies and implementation measures have just been introduced. The relevant state departments should not only encourage the development of new energy vehicles, but also parallel heavy and medium-duty vehicles should be the focus of energy conservation and emission reduction.
Most commercial vehicle emissions
In recent days, haze has continuously harassed most of our country and brought great threats to people's physical and mental health. Some experts pointed out that automobile exhaust emissions are one of the causes of haze. According to data from the environmental protection department, in 2011, the country’s motor vehicle emissions were 46.079 million tons, 3.5% more than in 2010, of which, the total national nitrogen oxide emissions The amount is 240.43 million tons.
China's traditional cars are generally divided into passenger cars and commercial vehicles. In the emission of pollutants, emissions from various models are not the same. According to the results of a study conducted by the State Environmental Protection Agency's Motor Vehicle Pollution Control Center in 2007 (Figure 1), the share of motor vehicle emissions for commercial vehicles with 3.5 tons or more is relatively high. Taking nitrogen oxides (NOx) as an example, heavy trucks account for 34.6% of medium-sized vehicles. 15.8% of trucks, 25.4% of big passengers, and 5.1% of Zhongke, together accounted for 80.9% of the total, and particulate matter emissions (including PM10, PM2.5, etc.) accounted for a higher percentage. It can be seen that although the number of commercial vehicles is about three times less than that of passenger vehicles, the displacement and annual mileage of bicycles are much larger than those of passenger vehicles, and the proportion of exhaust emissions is high. Emissions regulations and policies for commercial vehicles should be the focus of motor vehicle emissions control.
There are also significant differences in environmental pollution caused by different emission standards. The research conducted by the National Environmental Protection Agency also showed that the total number of cars in front of the National I Standard accounted for 9.5%, and that the four main pollutants discharged accounted for more than 40.0% of the total emissions, and they were in line with the National III and above standards. The car accounted for 53.7% of the total. Its emissions are less than 25.0% of the total emissions. This shows that emission upgrades are the most effective means of controlling and reducing vehicle exhaust emissions. Each upgrade of vehicle emission standards has achieved significant effects of significant reductions in emissions. It is no exception for the forthcoming implementation of the National IV emission standards.
Both autonomy and environmental protection should be grasped
In the face of tremendous pressure from environmental protection, improving engine technology has become a priority. It is widely believed that electronically controlled diesel injection systems and diesel engine post-processing devices are key to energy conservation and emission reduction. However, in these two areas, there is a certain gap between China and the strong state-owned automobile companies. Some companies have sought to establish joint ventures in order to rapidly improve their own technological level. However, the 30 year history of China's automobile industry joint venture shows that technology cannot be purchased. . In the face of environmental pressure, can only take the joint venture road?
Luan Ping thinks: “The development of independent industries is not in contradiction with environmental protection. High-level engine technologies in Europe and the United States and other automotive-powered countries have low levels of pollutant emissions, making them better than us, but their engine technology is also the result of independent research and development. ."
Luan Ping emphasized: “If we say that there is a large gap between our engine technology and foreign countries several years ago, that is a fact, but after more than 20 years of continuous efforts, the gap has been greatly reduced.†Guangxi Yuchai Machinery Co., Ltd. The R&D “Key Technology and Industrialization of Energy-saving and Environment-friendly Diesel Engines†project was ranked in the National Science and Technology Progress Award and won the second prize of the National Science and Technology Progress Award, which clearly demonstrated Yuchai’s technological progress as an autonomous engine company.
