In January 2015, the Ministry of Industry and Information Technology officially issued a research project on new energy vehicles in China. In two years, 41 cities across the country were selected as typical cities for data collection, collecting a large amount of data and gradually building Chinese automobile conditions. At present, the project has entered the verification phase of the working condition, and it is planned to end at the end of the year, and will be transferred to the application of the results next year. In the past two years, a major event in the auto industry seems to be being ignored. That is the China New Energy Vehicle Product Testing Research Project (hereinafter referred to as China's working conditions). CNC bending service is a process where Sheet Metal is bent to an angle using by a Sheet Metal Bender, typically a V shaped punch and die. It belongs to Sheet Metal Forming. The sheet is placed between the punch and die which presses down on the sheet. Cnc Bending process provides a low cost method to product 3D shapes from 2D sheets. CNC bending is a suitable for processing most ductile metals and primarily for sheet metal designs with one or more bends. Just a few examples of are brackets, Sheet Metal Cabinet,etc. There is generally no special tooling required, with the exception of intricate designs and special bends.

In fact, China's working conditions not only have a positive effect on the progress of the traditional automobile industry, but also have a greater role in promoting the development of the new energy automobile industry. At present, the new energy automobile industry does not have a complete set of international standards including the working condition detection method. In this case, the Chinese working condition law will enable us to more fully intervene in the international new energy vehicle standard. In the formulation.
The project started in 2015, and the Ministry of Industry and Information Technology, the Ministry of Environmental Protection, the National Standards Committee, and the Chinese Academy of Engineering jointly formed a project steering committee. The China Automotive Technology and Research Center took the lead in specific work. This is currently the world's largest vehicle testing project, involving the largest number of cities, and collecting the most data. At present, it has entered the verification phase of the working condition, and it is scheduled to be completed by the end of the year, and will be transferred to the application of results next year.
Working conditions are the basic standards of the automotive industry, directly affecting the fuel consumption, emissions and product announcements of automobiles, and their impact involves all vehicles produced in China.
If we started from the foundation of the first automobile manufacturing plant in 1953, China's automobile industry has gone through 64 years from small to large, from weak to strong. Today's output has been ranked as the "one brother" in the world for many years. However, it is embarrassing that the "one brother" who is flying all the way is wearing boots borrowed from the younger brother, and the more he runs, the more uncomfortable he feels.
The working condition method is an experimental method for evaluating the emission status of a vehicle (or engine). At present, there are three working conditions in the world: NEDC in the European Union, FTP75 in the United States, and JC08 in Japan. China's automobile pollutant emission limits and measurement methods from the first phase to the fifth phase, from the country I to the country V, are basically "equivalent to" the EU's NEDC working conditions law.
The EU's NEDC working conditions method has greatly promoted the development of China's automobile industry. Especially when China's automobile production and sales volume has increased explosively and suddenly faced serious environmental problems, the introduction of the EU's NEDC working conditions law, Improving the overall technical level of China's automobile industry and rapidly reducing vehicle emissions have played an immediate positive role. However, when China's automobile industry progressed from the primary school level to the high school level and the university level, and when the sleeves were prepared to fight with the world's top players, we found that we used the opponent's routines. This is a bit embarrassing and difficult to find. A win.
More importantly, the EU's NEDC method is based on the European car environment and vehicle characteristics, with typical European characteristics. The author has heard an unconfirmed claim: because European crude oil cannot be self-sufficient, Europeans first extract some useful chemical raw materials from crude oil refining before they go to refining gasoline and diesel. Since such oil performance does not meet the requirements of automobiles, the European automotive industry has invented many remedies, such as increasing the compression ratio of the engine cylinders, resulting in the addition of anti-explosive high-grade gasoline; for example, the promotion of exhaust gas recirculation turbines Pressure technology to make the oil burn more fully. In our country's refinery, the crude oil is directly cracked into gasoline, diesel, and kerosene. There is no procedure for extracting other components.
Compared with the FPT75 working condition method in the United States, the EU NEDC working condition method has a major feature, that is, its idle speed test has less time and short time, and the steady state, especially the high-speed state, has a long period of time and long time. As a result, the emission data is better, and the fuel consumption of the user when driving actually is significantly different from the NEDC working condition data. After applying to China, the deviation between test fuel consumption and actual fuel consumption is greater. This is one of the reasons why many consumers have reflected the difference between the fuel consumption of the mark and the actual fuel consumption after the implementation of the light vehicle sticker "Automobile Fuel Consumption Mark" in 2010. On February 10 this year, a set of data released by the China Working Conditions Project Team at the “China Working Conditions†2016 Annual Progress Report held in Tianjin was very amazing. The actual data collected by many cities in China and the announced fuel consumption (can be regarded as NEDC). Working conditions fuel consumption) difference of up to 34%. This shows that the EU NEDC working conditions law is inconsistent with China's national conditions.
As the basic standard of the automotive industry, the test conditions and test methods directly affect the fuel consumption and emissions of automobiles, which in turn affects the orientation of automotive technology and affects the development of independent brands. For decades, European automotive technology has dominated the Chinese automotive market, and repeated rounds of re-introduction have been mostly for European technology. The development of independent brands has also been benchmarked against European technology, and even foreign auto companies that have merged and reorganized Chinese companies have also European-based. We can't help but admit that the European standard represented by the NEDC working condition method has set a corridor for the development of China's automobile industry technology. Whether it is a Sino-foreign joint venture or a self-owned brand enterprise, it can only go smoothly along this corridor. Perhaps this is one of the reasons why the original intention of the market-changing technology has not been realized, and the independent brand enterprises have struggled to break through for many years and have not achieved much.
In the past two years, the Beijing VI emission standards dispute has been raging. Although Beijing finally gave up Beijing VI and waited for the implementation of the national VI standard, it can be seen that Beijing, the most stringent vehicle emission standard in China, has already considered European emissions. The standard does not meet the demand.
An interesting phenomenon is that the EU is also preparing to change. It is reported that starting from 2017, the EU will absorb the WLTP vehicle emission test standards. The full name of WLTC is "World Light Vehicle Test Cycle". The EU's transformation just shows that the EU also recognizes that the NEDC's working conditions law needs to be eliminated, and it seems to be telling us that China should also change.
China's working conditions project has been carried out for two years, with investment of more than 100 million yuan, dozens of team efforts, 41 cities, more than 4,600 vehicles, 32 million kilometers, including data collection of 3.3 million kilometers of new energy vehicles. In addition, there is a total capacity of 300GB, including 40 cities, 300,000 road GIS traffic low-frequency dynamic big data. The construction of light passenger cars, light commercial vehicles, and the operating conditions of five major commercial vehicles. At present, the "Chinese working conditions" have been submitted to the National Standards Committee, and the conversion between the old and new experimental methods has also been put on the agenda.
China's working conditions have a positive effect on the progress of the traditional automobile industry and have a greater role in promoting the development of the new energy automobile industry. In recent years, China has introduced many new energy vehicle policies, but most of them are fiscal and phased policies, and they are more than 2020. Policy adjustments after 2020 should be based on China's working conditions standards, and coordinate vehicle technology progress, life cycle emissions, energy consumption, fiscal and taxation policies, and administrative support measures to find the best point of convergence and establish science. A sound policy system.
All in all, the formulation and implementation of China's working conditions will play a leading role in leading China's auto industry to break through foreign technology corridors and promote independent development of independent brands. For the new energy automobile industry, under the current world without a complete set of international standards including the working condition detection method, the Chinese Working Conditions Law will enable us to more fully intervene in the formulation of international new energy vehicle standards. .
