On the first day of work after the Spring Festival, we saw the Notice on Implementing the Management of Fuel Consumption for Heavy Commercial Vehicles (hereinafter referred to as the “Noticeâ€) on the official website of the Ministry of Industry and Information Technology. The “Notice†stipulates that as of February 1, 2012 In the management of "Vehicle Production Enterprises and Products Announcement" (hereinafter referred to as the "Announcement"), the management of fuel consumption for heavy-duty commercial vehicle products (excluding dedicated operations and all-wheel drive products) is implemented. Shortly before this, the "Limited Fuel Consumption Limit for Heavy-duty Commercial Vehicles (Phase 1)" has been officially released and will be formally implemented on July 1 this year. This means that the Ministry of Industry and Information Technology and the Ministry of Transport have officially entered the era of dual management of fuel consumption for heavy commercial vehicles.
Although the “Notice†treats the dual management of heavy-duty trucks that have received much attention and controversy as humane, the undisputed fact is that the dual management of the Ministry of Industry and Information Technology and the Ministry of Transport will bring to the company. Heavy burden.
â– Loose limit criteria are loose
On December 31, 2011, the Ministry of Industry and Information Technology issued the No. 51 document of 2011, approving the automotive industry standard for the “Limit of Fuel Consumption of Heavy Commercial Vehicles (Phase 1)â€, standard number QC/T 924-2011. The standard stipulates the limits for the fuel consumption of heavy commercial vehicles. It is applicable to commercial vehicles burning petrol and diesel with a maximum total design mass of more than 3,500 kg, including trucks, semi-trailer tractors and passenger cars; it specifies fuel consumption. General requirements, limits, and production consistency.
Before the Spring Festival, he interviewed Tan Xiuqing, deputy general manager of Shandong Heavy Industry Group Co., Ltd. He said that the standard of fuel consumption for heavy-duty commercial vehicles is very low, and almost all mainstream domestic models can meet the requirements.
Kim Yoo-fu, the deputy director of the National Automobile Standardization Technical Committee and the chief drafter of the “Limits for Fuel Consumption of Heavy-duty Commercial Vehicles (Phase 1)†told reporters that the Ministry of Industry and Information Technology is not only concerned with the test methods but also on the requirements for variant vehicles. All of them are always regulated by the principle of "relatively loose early industry standards and progressively stricter national standards."
Several domestic heavy-duty truck companies did not worry too much about the standards of the vehicles. “At present, domestic mainstream heavy-duty truck companies are already working on the development of traditional automotive energy-saving technologies, such as light weight. Domestic diesel engine companies are also striving to break through the fuel-efficient engine technology, so our attention is not on 'how many models can achieve compliance' Instead, it was placed on 'how to properly manage the state's relevant departments'," said a person in charge of a heavy truck company.
â– "Notice" is intended to reduce the burden
“Ministry of Industry and Information Technology and Ministry of Transportation and Communications jointly determine the testing organization for fuel consumption inspection of heavy commercial vehicles, and report on their fuel consumption inspections; set up a joint working group to jointly supervise and monitor the fuel consumption inspection of heavy commercial vehicles. When carrying out sample vehicle inspection, fuel consumption of working mode or road comprehensive fuel consumption inspection may be carried out, and the fuel consumption of working mode and road fuel consumption inspection may be jointly tested, and the company shall not be required to repeat sample delivery vehicles. Press a test fee." This passage in the "Notice" makes the company feel the good intentions of the Ministry of Industry and Information as far as possible for the company to reduce the burden. This is also the essence of the "Notice": "One for two" reduces the burden on the company.
Before the Spring Festival of the Year of the Dragon, the Ministry of Industry and Information Technology had organized a "Guangzhou Conference" at the Guangzhou Mansion in Beijing. The meeting was attended by representatives of the Ministry of Transport and Inspection, and representatives of domestic heavy-duty commercial vehicle companies. They conducted a new "how to manage" the meeting. Round negotiations.
“At the meeting, the Ministry of Industry and Information Technology negotiated with the Ministry of Transport that the inspection agency could make two reports to the inspection agency and one to each of the Ministry of Industry and Information Technology and the Ministry of Transport. The management method is still scientific, according to a person in charge of a heavy truck company.
In addition to reducing the burden on enterprises through "one for two," the "Notice" also requires that, starting on July 1, 2012, the above-mentioned products (excluding dump trucks and city buses) that are newly declared in the "Announcement" are subject to the operating mode fuel consumption. The value should meet the requirements of the industry standard QC/T924-2011 Heavy Fuel Consumption Limit for Commercial Vehicles (Phase 1). Products that do not meet this limit must not be included in the "Announcement." “If the road test for fuel consumption of heavy-duty commercial vehicles has to be set, then the source (announcement at the product announcement) is most beneficial to the company. When previously announced on the product, there was no fuel consumption requirement for heavy-duty commercial vehicles. The owner of the vehicle has already announced the vehicle operation certificate." The person in charge said, "But it is inevitable that in the future when the owner of the operation certificate, the procedures will be more troublesome, the cycle will be longer."
Reduction of burden only reduced "fur"
In the face of the dual management of the heavy-duty vehicle fuel consumption by the Ministry of Industry and Information Technology and the Ministry of Transport, although the two sides negotiated a “one-for-two†approach to reducing the burden on the company, relevant persons of the heavy-duty truck companies will certainly “prepare actively,†over and over again. Strictly enforced, the reporter still felt the helplessness, resentment and sadness of the company.
“About the management of fuel consumption for heavy-duty commercial vehicles, we have already said a lot, what continue to say? What is the use of the joint report? We have expected the fuel consumption management of the two ministries to be combined into one and now it seems that this is not. It is possible that if the two fuel-fired fuels are a foregone conclusion, companies must bear the burden of double-checking.The cost of testing a prototype is at least 30,000 yuan higher. It cost 670 million yuan," said a person in charge of a heavy truck company.
The "Notice" stated that it is possible to carry out inspections together with the fuel consumption of working conditions and the fuel consumption test of the road comprehensive method, and it is not allowed to require companies to repeat sample delivery vehicles. If there are many experimental projects that can be cross-recognized by the two ministries and commissions, this "one-for-two" approach can indeed greatly reduce the burden on companies, but this is not the case. “The Ministry of Industry and Information Technology adopts a test method for working conditions, and the Ministry of Transport uses a constant speed fuel consumption test method. Since there are essential differences between the two test methods, only a few test items that meet the conditions of 'one for two', most The pilot project will have to be done twice. Therefore, reducing the burden is only 'fur'," a company official told reporters.
"A lot of testing procedures will inevitably bring pressure on the company. Companies will also share this pressure with users. This year, heavy truck product prices may increase, which will also affect the market. "A person in charge of a heavy truck company reluctantly indicated.
