On March 13, 2011, Meng Xiangrui, deputy to the National People's Congress and director of the Science and Technology Industry Department of Anhui University of Science and Technology, said that with the increase in the number of heavy trucks in the extractive industry and urbanization construction, the negative effects are even more pronounced. Noise pollution, road destruction, the greenhouse effect of tail gas emissions, and damage to the ecological environment should be addressed and resolved. The data shows that in 2010, heavy truck sales reached 880,000, of which 75,000 were for overdraft demand; in 2011, the expected sales volume of heavy trucks was 912,000 units, and the average annual growth rate in the next five years is still expected to remain around 15%. As China's urbanization rate is still advancing, fixed assets will maintain a high growth rate, and the demand for commercial vehicles such as heavy trucks will be positively correlated. With the increase in the shift of manufacturing industries to the central and western regions, the demand for heavy-duty long-haul trucks in the central and western regions will increase rapidly.
With the rapid increase in the number of heavy-duty trucks, the destruction of complex geographic landscapes in the west and the deterioration of the fragile ecological environment pose serious challenges. In order to adapt China to become the main market for heavy trucks in the future and reduce the environmental pollution and damage caused by heavy trucks, four suggestions are proposed:
First, to strengthen the research and development of heavy truck engines. The core of heavy trucks is diesel engine technology. In accordance with the requirements of international standards, China has shifted from the country's three emission upgrades to the national four emission standards, but it is required to achieve important breakthroughs in related technologies. In recent years, China has increased the research and development of automobile engines. In terms of the performance of heavy-duty diesel engines, it has reached or approached the international advanced level. However, due to different emission standards (economic impacts and dynamics are affected by the selection of emission indexes), and international advanced There are still some gaps between products, and the product's independent development capability needs to be improved.
Second, improve the quality of oil products and develop a new generation of plasma synergistic catalytic diesel exhaust gas purifiers. The oil problem has a direct impact on the degree of environmental pollution caused by heavy-duty truck exhaust gas. As China has fully implemented the national three emission regulations, most of the oil products remain in the country two or lower except Beijing, Shanghai and other major cities. Level. At the same time, solving the particulate emissions from diesel engines is the key to promoting the use of diesel engines in automobile power. However, traditional catalysts and other traditional technologies are used in China to purify the exhaust gas of diesel engines. The removal efficiency is not high, and secondary pollutants are also generated.
Third, develop van transport, drop-and-hook transport, and automobile trains, and encourage the development of freight models to multi-axis, heavy-duty, and van-type. With the continuous improvement of the status of container transport in road transport and the emergence of benefits. Heavy trucks have broad prospects for economic benefits. The development of van-type transport, dump-and-hang transport, and automobile trains can improve transport efficiency and save energy consumption. Large-capacity container truck transport has become the development direction of road transport.
Fourth, increase the research and development of heavy truck new products and explore new products that use natural gas and electricity as main energy sources. China’s energy status is rich coal, lean oil, and low gas, but it has abundant natural gas recoverable reserves, which is enough to support the development of China from 150 years to 200 years. We have provided clean energy guarantees for the transformation of our country's heavy trucks with natural gas as fuel.
