Recently, the “Coverage Fuel Consumption Limit for Heavy-duty Commercial Vehicles†drafted by the China Automotive Technology and Research Center (third phase, consultation draft) has been completed and is being submitted to the Ministry of Industry and Information for approval.
Although this draft is under review and has not yet been formally announced, the relevant drafting parties are more cautious and do not want to talk about it. However, the reporter has obtained some important information through various efforts.
Reduce fuel consumption trend <br> <br> present, China's automotive gasoline and diesel consumption accounting for the proportion of gasoline and diesel consumption has reached about 55%, 70% or more each year to add new oil consumption of automobile consumption. In 2014, China’s apparent oil consumption exceeded 518 million tons, and net oil imports for the year were approximately 308 million tons, with an external dependence of 59.5%. It is expected that in the coming period of time, China’s car ownership will continue to grow, and the resulting energy shortage will become more prominent. Heavy commercial vehicles account for about 10% of the total automobile production and sales volume. However, due to the high fuel consumption of heavy-duty commercial vehicles and the longer mileage, the total amount of oil consumed by heavy commercial vehicles is much higher than this ratio.
A member of the Standards Drafting Group, who asked not to be named, told reporters that lowering the fuel consumption of commercial vehicles is not only energy-saving and environmental protection, but also the consideration of enhancing national energy security. Anhui Hualing Automobile Co., Ltd. is one of the participating drafting companies. Fang Yi, deputy general manager of the company's marketing division, said: "Energy saving and emission reduction, cost reduction and efficiency increase are not only the needs of transport companies and medium-to-heavy truck manufacturing enterprises in the transformation and upgrading, but also Corporate Social Responsibility: Reducing the fuel consumption limit of commercial vehicles is of great significance for environmental protection and energy conservation. In particular, China is in a phase of rapid economic development. The demand for energy is huge, and commercial vehicles are the main consumers of fossil energy. one."
Xing Min, executive vice president and secretary-general of the China Internal Combustion Engine Industry Association, said that in the near future, the United States and Europe have new requirements on the fuel consumption limit standards, and China should also pay close attention to the promotion of the third phase of the limit, narrowing the standards with developed countries. difference.
The members of the standard drafting group told the reporter that the “Energy Conservation and New Energy Vehicle Industry Development Plan (2012-2020)†issued by the State Council proposed that by 2020, the fuel consumption of new vehicles for commercial vehicles will approach the international advanced level. In 2014, the China Automotive Technology and Research Center formally launched the work on the formulation of the “threshold value of fuel consumption for heavy commercial vehicles†(the third phase).
Considering targeting <br> <br> It is understood that the drafting of standards, many companies involved, their cost and technical analysis based on individual circumstances. SAIC Iveco Hongyan Commercial Vehicle Co., Ltd. is one of the participating drafting companies. Its responsible person stated that truck manufacturers are also striving to continuously reduce fuel consumption because users' demands for fuel consumption are constantly increasing. Based on the needs of users, companies are actively researching and reducing Fuel consumption method.
Fang Yi told reporters that Zhongzhong trucks are relatively complex and require careful consideration of the fuel consumption limit standards for heavy vehicles. They cannot be generalized for all similar vehicles. They need to be close to the actual situation and be classified and refined. Feng Feng, manager of the Commercial Vehicle Working Group at the European Automobile Industry Association Beijing Representative Office, said that different technologies correspond to different working conditions, and the application of energy-saving technologies should be compatible with the actual conditions of the vehicle. Taking into account the actual operating conditions of different types and qualities of vehicles and the potential for energy-saving technologies, there are great differences, so the energy-saving goals should be subdivided according to the type and quality of vehicles.
The members of the standard drafting group told reporters that at present, the test methods, loads, and units for evaluating the fuel consumption of various heavy-duty commercial vehicles vary from country to country, and it is impossible to directly compare the standard technical indicators. It is necessary to compare and convert the measurement methods of different countries and regions. Therefore, the process of standard setting is very complicated and has gone through many stages. He said: "The standard must set a feasible goal. When formulating standards, we must consider the potential of energy-saving technologies for different models, and the affordability of commercial vehicle users to increase their purchasing costs." Ultimately, in this consultation draft In the report, it was determined that the “fuel consumption limit based on 2015 will be tightened by approximately 15% in 2020†as the overall energy saving target.
Truck promote technological progress <br> <br> standard if implementation of the third stage, will undoubtedly promote the truck industry technology upgrades, including new technologies, the application of new materials. Reducing overall vehicle fuel consumption is related to engine, component technology, transmission efficiency and steering system improvements, and the technical level of electronic control systems. The members of the standard drafting group stated that in order to meet the new standards, companies need to apply advanced technologies that reduce energy consumption. The reduction in fuel consumption of vehicles requires the further improvement of exterior design and reduction of wind resistance. The engine itself must also be energy-efficient, thereby promoting the improvement of engine technology. Therefore, the implementation of the new standard will promote the improvement of the entire vehicle and engine technology.
China National Heavy Duty Truck Co., Ltd. is also one of the companies involved in the drafting of standards. Yao Zhangtao, director of the MC11 and MC13 engine design institutes of its Technical Center Power Institute, said: “Currently, the thermal efficiency of the engine can be increased to over 40%, and the thermal efficiency of the engine fuel can be increased to 50%. Under the working conditions, it will be increased to 55%, which is the ultimate for the engine. If you want to further improve the fuel economy of the vehicle in the future, you may need to use advanced engine exhaust gas preheating technology.†Yao Zhang Tao added; Reducing the fuel consumption of the entire vehicle, besides the engine, is related to the driver's resistance, transmission system efficiency, tire resistance, vehicle quality, etc. The new standard may promote the application of aluminum materials, and companies have already studied the use of aluminum for heavy trucks. Alloy frame."
Tan Xiuqing, an expert from the China Association of Automobile Manufacturers, told reporters: “The key to reducing the fuel consumption of commercial vehicles is to match the engine with the vehicle.†Fang Yi said: “The logistics, transportation, and other aspects of the logistics industry are further detailed The subdivision will promote the subdivision of commercial vehicle product configuration. This requires that vehicle manufacturers not only increase R&D investment in the transmission assembly, but also carry out scientific product planning and market segmentation in the vehicle application field. Also cooperate with parts and components companies on technologies to improve transmission efficiency and reduce fuel consumption."
“Initial industry transformation and upgrading †“This is a mandatory technical standard. One of the important properties of the mandatory standard is that not all audiences can achieve it. Instead, it encourages advanced and eliminates backwardness. Some companies can meet standards and some can work harder. Achieving, and some will be eliminated, this is the significance of setting standards.†Feng Feng told reporters, “If this standard is introduced, it will make no sense for all companies to achieve, and vice versa. So by 2020, China will The engine and heavy truck industry will have some adjustments."
“The impact of this standard is relatively wide, and it has a greater impact on the heavy-duty truck industry. After the future implementation, some engine companies that cannot meet the requirements of the technology will gradually be eliminated.†Xing Min told reporters, “On January 1 this year, the internal combustion engine industry The “Code of Practice†has been formally implemented, and this standard has also been formally introduced. The combination of the two standards is very beneficial to the transformation and upgrading of the industry and structural adjustment.â€
Tian Bin, director of China Heavy Truck Chengdu Wangpai Commercial Vehicle Co., Ltd. Technology Center Medium and Heavy Truck Research Institute, said that after the implementation of the third phase of the standard, it will have a huge impact on the engine industry. In the long run, it will eliminate engine companies with backward technology and poor R&D capabilities. It will further promote our heavy truck technology.
Fang Yi told reporters: “The new fuel consumption limit standards are constantly escalating. In the short term, it will promote the technical upgrading of vehicle products. In the long term, with the gradual improvement of national standards and industry regulations, it will also promote the organizational structure of China’s medium and heavy truck companies. , management level, transformation of manufacturing model, the medium and heavy truck manufacturing companies will develop to the development of organizational structure, fine management, intelligent manufacturing and other aspects."
In addition, with the increasingly stringent vehicle fuel consumption limit standards and the country’s increasing emphasis on new energy research, it will promote the development of new energy technologies for medium- and heavy-duty trucks, and may achieve breakthroughs in new energy technologies for medium and heavy trucks in the future.
If implemented, Heavy Fuel Consumption Limits for Commercial Vehicles (Phase 3) will undoubtedly promote technology upgrading in the truck industry. To meet the new standards, companies need to apply advanced technologies that reduce energy consumption. Reducing the fuel consumption of the entire vehicle requires further improvement of the exterior design and reduction of wind resistance. The engine itself must also be energy-efficient, thereby promoting the improvement of engine technology. The implementation of the new standard will promote the improvement of the entire vehicle and engine technology.
