What policy support does the automobile light weight industry have?


Car enterprises, auto parts enterprises, materials enterprises, are increasingly concerned about lightweight cars. What policy support does the automotive lightweight industry have?

At present, the world oil reserves are decreasing day by day. With the increase of car ownership, the automobile has become the main consuming body of oil. China is the world's second largest energy consuming country, constantly improve the degree of dependence on foreign oil, oil supply pressure increasing, vehicle fuel has accounted for China's annual oil consumption of 1/3, the car as the gas guzzler, its energy level has affected the overall energy consumption of water in China ping. In the face of oil supply and global warming, raging haze and environmental pressures, China's strict passenger car fuel consumption standards and regulations, on the emission of CO2 passenger car fuel consumption and the corresponding put forward strict requirements, 2015-2020 years, China's fuel consumption fell significantly greater than in other countries.

In order to realize energy saving and consumption reduction, the car enterprises can develop new energy vehicles, adjust product structure, develop efficient drive systems, and auto light weight and so on. Among them, lightweight is the most effective way for car enterprises to adopt. In the process of running, the traction force of the automobile needs to overcome three main resistances: the inertia of air resistance, the ground friction force and the change of speed. Inertia and friction force is proportional to the weight and. The reduction of automobile quality can greatly reduce these two resistances, and improve the fuel economy of automobile. It is understood that the body weight will consume more than 40% of the fuel, and the test shows that the quality of each car is reduced by 100 kg per hundred kilometers fuel consumption will be reduced by 0.4-1 L, the quality of its own car every 10% reduction in fuel consumption can be reduced 6%-8% emissions will be significantly reduced, and the safety performance, control performance, environmental performance indicators of lightweight automobile concern to consumers have important significance.

The country for energy consumption have successively formulated a series of industrial policies, mainly from the more standard and the technical route of strict guidance, effectively promote the lightweight car, let us learn more about these policies.

Country five emission standards phased implementation

The state environmental protection department and the Ministry of Industry issued a notice: from April 1, 2016, 11 provinces and cities including the north of Guangzhou, to fully implement the standard five emission vehicles, all the import, sale and registration of light-duty gasoline vehicles (passenger cars), light-duty diesel passenger cars and heavy-duty diesel vehicles are required to meet the national emission standards for five. The national standard five emissions will start from the 11 eastern provinces and cities to the country, starting from the bus, sanitation and post use gradually extended to all trucks, from April 1, 2016 to January 1, 2018, sub regional, sub periods, stages of implementation.

Europe and the United States in the last century in 60s had been aware of the harm of automobile emission in 1970 or so, have enacted relevant emission standards, and with the development of the times and needs, and emission standards are constantly improving and perfecting in. In 80s of last century, our country began to formulate emission standards. By 90s, our standards had been set up on the basis of reference to European emission standards.

The country's five standard, equivalent to the European Union's five European standard, has been implemented since 2009, and its restrictions on emissions of nitrogen oxides, hydrocarbons and other vehicles are even more stringent. From country I to country IV, cycling pollution decreased by 30% to 50% per second.

Fourth stage fuel consumption standard implementation

In 2012, the Ministry of industry and information technology organized the national automobile Standardization Technical Committee to start the formulation of the fourth stage standard (2016-2020 years) for the fuel consumption of passenger cars. On the basis of the research on the implementation of current standards, energy saving potential and economic cost of our country, the fourth stage standard project has been formed through extensive consultation. GB 19578-2014, the fuel consumption limit for passenger cars, was officially launched in December 22, 2014 and implemented on January 1, 2016.

GB 19578-2004, the limit of fuel consumption for passenger cars is the first mandatory national standard in the field of automobile energy conservation in china. From the beginning of the standard, the establishment and implementation of the energy management system of the automobile, will have passenger cars, light commercial vehicles and heavy commercial vehicles into the "vehicle manufacturers and product announcement" management regulations, must meet the corresponding fuel consumption limits in China's production and sales of vehicles.

The newly revised standard of fuel consumption for passenger cars provides the upper limit for fuel consumption in China, and is implemented in two stages. After the implementation of the first phase of standards, China's existing automobile fuel consumption level will be reduced by 5%-10%, after the second phase of implementation, fuel consumption will be reduced by more than 15%. Each year will set fuel consumption standards, by 2020, car prices will limit the fuel from 2015 6.9L/ km down to 5.0L/100 km, an average annual decline of about 6.2%.

The implementation of the new standards will make the automobile manufacturing enterprises pay more attention to the energy saving of automobiles, and spare no effort to develop the lightweight technology to reduce the quality of car bodies. Plastic parts as the most effective means of reducing the quality of the body, will be encouraged by the policy of energy conservation, more models are adopted, so the standard will undoubtedly promote the development of plastic auto parts market.
