Reliability MTBF ≥ 4000 hours, CO2 emissions are reduced by 10% to 15%, fuel consumption is reduced by 10% to 15%, matching models cover light, medium, and heavy-duty diesel engines, fully meeting the national IV or above emission standards.
The development of energy-saving and emission-reduction
Xing Min, executive vice president and secretary-general of the China Internal Combustion Engine Industry Association, said that accelerating the research and development of energy-saving new technologies and industrialization, accelerating the diversification of alternative energy sources, and accelerating the development in the manufacturing industry are the development of energy-saving and emission reduction in the internal combustion engine industry. Ideas.
One of the key tasks in the development of the 12th Five-Year Plan for China's internal combustion engine industry is to develop engines for low-energy-consuming, low-emission vehicles and various alternative fuels. He also stated that the development strategy for the internal combustion engine industry is to strive to achieve the grand goal of transforming from a producing country to a producing country around 2020, and making positive contributions to the realization of China's economic transformation and upgrading and improvement of social ecological benefits.
At present, there are still some outstanding problems in the energy conservation and emission reduction of China's internal combustion engine products, such as the low level of comprehensive energy efficiency, the lower proportion of advanced internal combustion engine energy-saving products, the development of alternative fuel internal combustion engine products at the initial stage, and the weak foundation for the green manufacturing and remanufacturing of internal combustion engines. Industrial policies need to be further improved and a series of other.
Xing Min has his own views on these issues. “The internal combustion engine industry is an important basic industry in China, and it is the focus of investment in the global equipment manufacturing industry today. The next major step in China’s efforts to promote energy-saving and emission reduction of internal combustion engines must be based on China’s energy security. , To address climate change and improve the competitiveness of the internal combustion engine industry, to reduce energy consumption, reduce carbon dioxide emissions as the main line, to reduce fuel consumption as the overall goal, play the role of the main body of enterprises, focus on breakthroughs, accelerate the development of energy-saving internal combustion engine technology and industrialization Promote and accelerate the development of the manufacturing industry."
The diversified development of energy-saving and emission-reduction refers to many aspects, such as improving the energy efficiency of internal combustion engines, reducing the energy consumption of production processes, developing alternative energy sources, and improving laws and regulations. While completing energy-saving and emission-reduction, the comprehensive strength of the industry's own scientific research capabilities and technological level will also be raised.
It is understood that in the "12th Five-Year Plan" of the internal combustion engine industry, commercial vehicles, diesel engines for passenger vehicles, and gasoline engines for passenger vehicles that meet the requirements of national emission regulations will be developed to meet the high power density diesel engines for various types of special vehicles. Powered passenger vehicles and extended-range internal-combustion engine electric vehicles, focusing on the development of alternative fuel engines such as natural gas, methanol, and bio-fuels, and the development of components for advanced internal-combustion engines, have been included in key development product areas.
Incentive mechanism to mobilize emission reduction enthusiasm
The "Opinions of the General Office of the State Council on Strengthening the Energy-saving and Emission Reduction of the Internal-combustion Engine Industry" (hereinafter referred to as the "Opinions") drafted by the Ministry of Industry and Information Technology and the China Internal Combustion Engine Industry Association have been officially issued by the General Office of the State Council.
The internal combustion engine is not only the largest body of oil consumption in our country, but also the most important manufacturer of pollutants in China, and it is the industry with the most excavated space for implementing energy-saving and emission reduction. The issuance of the "Opinions" precisely captures the "bull nose" of energy conservation and emission reduction.
Yan Xuguang, chairman of the China Combustion Engine Industry Association and chairman of Weichai Power Co., Ltd., has such suggestions for the publication of the "opinion". "First, it is recommended that relevant government departments establish and improve the policies, regulations and standards system for energy-saving and emission reduction of internal combustion engine products as soon as possible." Accelerate the increase in the proportion of advanced low-energy and low-emission internal combustion engine products and the proportion of social ownership; Second, it is recommended that relevant government departments increase investment in research and development of energy-saving emission reduction technologies and incentives for enterprises, and improve their independent innovation capabilities. The key core technologies of the internal combustion engine improve the international competitiveness of internal combustion engine companies."
Enterprises will inevitably pay for technological upgrades. If the government introduces relevant policies, it will reduce or exempt the financial direct subsidies policy for the purchase of low-energy consumption and low-emission vehicle purchase taxes, adopt policy-based measures to eliminate energy-intensive and high-emission products, and design energy-saving measures. The relevant incentives and penalties for emission reduction must be able to mobilize the enthusiasm of the companies in implementing emission reductions, and at the same time, they can also crack down on frauds such as “Fake Country IVâ€.
Gao Yunhu, Director of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology, said that the Ministry of Industry and Information Technology will join hands with the internal combustion engine industry to promote the development of energy conservation and emission reduction.
He said, “The Ministry of Industry and Information Technology will further accelerate the R&D, innovation and promotion of internal combustion engine energy-saving and emission reduction technologies, promote the scale and standardization of the remanufacturing of internal combustion engines, improve relevant standards systems, and promote the formation of a cyclic production and consumption model for the internal combustion engine industry. Remanufacturing industrial market, comprehensively improving the comprehensive competitiveness of China's internal combustion engine industry." 
Energy-saving and emission reduction can fully improve the strength of the internal combustion engine industry
