Commercial vehicle companies paid attention. Recently, the drafting of mandatory national standards for "the fuel consumption limits for heavy commercial vehicles" was completed. From September 24, the official website of the Ministry of Industry and Information Technology began a one-month consultation. The standard is applicable to commercial vehicles burning petrol and diesel with a total design mass greater than 3500kg, including trucks, semi-trailer tractors, passenger cars, dump trucks, and city buses. Fuel consumption limits for various types of models with different masses have been made. Detailed regulations.
However, industry insiders pointed out that the Ministry of Communications had previously supervised the fuel consumption value of commercial vehicles, and the long-term management of national ministries and commissions will increase the detection burden for commercial vehicle manufacturers, and increase the cost of enterprises while reducing energy consumption.
The purpose of this national standard for the huge energy consumption of commercial vehicles is obvious, and it constrains the huge energy consumption of heavy commercial vehicles. Relevant data show that Chinaâ€™s commercial vehicle population accounts for nearly 20% of domestic vehicles, but the overall fuel consumption accounts for nearly 50%; and the International Energy Agencyâ€™s report shows that the current energy consumption in the transport sector accounts for the total global energy consumption. 20% is enough to see the huge energy consumption of commercial vehicles that mainly undertake transportation tasks.
According to the content of the consultation draft, the standard specifies the limits for fuel consumption of heavy commercial vehicles and is applicable to commercial vehicles burning petrol and diesel with a total design mass greater than 3500 kg, including trucks, tractor-trailers, passenger cars, and dump trucks. And city buses. According to the difference of the maximum design total mass, the fuel consumption limit of trucks ranges from 13 to 45.5 litres per hundred kilometers; the fuel consumption limit of semitrailer tractors ranges from 33 to 48 liters per hundred kilometers; the fuel consumption of passenger cars varies. Limits ranged from 12.5 to 100 kilograms to 29.5 liters; fuel consumption limits for dump trucks ranged from 15 to 49 liters per vehicle; passenger car fuel consumption limits rose from 14 to 49 liters per 100 kilometers.
Rising testing costs Although the original intentions of the relevant departments are good, some people in the industry questioned that compared with the relevant standards issued earlier by the Ministry of Communications, the standards set by the Ministry of Industry and Information Technology have nothing new in the regulation of fuel consumption, but only added a large number of new vehicles. The cost of entering the car companies added more trouble.
It turned out that as early as 2009, the Ministry of Communications announced the "Measures for the Inspection and Supervision of Fuel Consumption of Road Transportation Vehicles." At the beginning of 2011, with the full implementation of this management approach and the tightening of the â€œlimit valueâ€ standard set up by the Ministry of Industry and Information Technology, the overlapping of departmental responsibilities and cross-management issues began to appear.
According to industry sources, the Ministry of Industry and Information Technology is in charge of new vehicle access certification. Before each new car is listed, it must meet the standards set by the Ministry of Industry and Information Technology before entering the new car catalog; and the Ministry of Communications in charge of road operations, commercial vehicles cannot report fuel oil to the inspection standard, and it will be difficult to obtain operations. Certificate.
Informed sources revealed that after the implementation of the national standard, the inspection cost of a large-scale commercial vehicle company may rise in a straight line. Now, the cost of a commercial vehicle exhaust emission test is approximately 1.5 million to 1.8 million. The cost of fuel consumption inspection is certainly not Will be lower than this number. In addition, the refinancing of vehicles has to be re-listed. The cost of fuel consumption testing for a year is not small.
Technological innovation and policy implementation go hand in hand In the IEA's view, if governments around the world can actively implement policies to promote advanced technologies, new car energy consumption will be halved from the current 20 years later, and the global dependence on oil will be greatly reduced.
Now, there are many car companies that are embarking on the promotion of energy-saving technologies for commercial vehicles. Recently, Foton Motor Co., Ltd. (600166) launched a heavy machinery project. At the same time, it also cooperated with a number of central enterprises on strategic cooperation in clean energy equipment and vigorously developed technologies such as diesel engine energy-saving emission reduction and hybrid power.
In addition to Futian, Yutong, BYD and other car companies are also actively developing hybrid buses. In the same field, German experts have developed buses that run on hybrid engines. The bus, which is 31 meters in length, has become the longest bus in the world.
