Fuel consumption management of heavy commercial vehicles is beneficial to green tires

the industrial policy department of the Ministry of industry and information technology recently issued the "notice on the implementation of fuel consumption management of heavy commercial vehicles" in the document of the Ministry of industry and information technology Lianye [2012] No. 12. The notice said that on October 24, 2015, in order to further promote energy conservation and emission reduction in the automotive industry and promote the technological upgrading of heavy commercial vehicles, it was decided to implement fuel consumption management for commercial vehicles (hereinafter referred to as heavy commercial vehicles) with a maximum design total mass of more than 3500kg and fuelled with diesel and gasoline from February 1. This measure will help promote the greening process of radial truck tyres

the notice requires that in the management of vehicle production enterprises and products announcement, fuel consumption management should be implemented for heavy commercial vehicle products (excluding special operation products and all wheel drive products). The Ministry of industry and information technology and the Ministry of transport jointly determine the testing organization responsible for the fuel consumption testing of heavy commercial vehicles, and approve its fuel consumption testing report. On the basis of ensuring that the products meet the requirements of standards and regulations such as safety and environmental protection of heavy commercial vehicles, relevant vehicle manufacturers should actively promote the research on energy-saving technology of heavy commercial vehicles, improve the fuel economy level of heavy commercial vehicles, and meet the requirements of relevant fuel consumption standards

the implementation of this measure will make automobile OEMs pay more attention to the green process of supporting tires. It is understood that in the process of driving, it takes 40% of the fuel to overcome the wind resistance, 25% to overcome the internal mechanical resistance, and 35% to overcome the tire rolling resistance. The fuel consumption caused by tyres accounts for about 20% of the fuel consumption per tank of cars, accounting for 1/3 of passenger cars. Therefore, using green tires without changing the vehicle structure can improve the fuel economy of heavy commercial vehicles HB 5287 ⑴ 996 metal material axial loading decadent experimental method

the rolling resistance of the tire comes from the force generated by the friction of various parts inside the tire, which makes the tire generate heat in the process of movement and deformation, and then consumes fuel. Therefore, reducing the rolling resistance is of great significance to tire fuel conservation. By improving the compound formula and replacing carbon black with white carbon black, the tire can consume the least energy, optimize the carcass structure design and pattern design, and reduce the rolling resistance. Relevant test results show that every 5% reduction in rolling resistance can save about 1% of fuel

therefore, tire enterprises should actively develop green fuel-efficient tire products with low rolling resistance. In the current environment of China, fuel saving is a common concern, whether it is government policies, the demand of the automotive industry or the cost control of the transportation fleet. In addition, the EU tire labeling law will be officially implemented on November 1 this year, and South Korea will also implement relevant laws and regulations in the same period. Only if it meets the requirements that its rolling does not have oil leakage and other phenomena, and the company will not slow down, slippery and noisy when going out, can tires be exported to these regions
