China Development Portal News The Ministry of Environmental Protection and the General Administration of Quality Supervision,Inspection and Quarantine of the People's Republic of China recently released the"Light Vehicle Pollutant Emission Limits and Measurement Methods(China's Sixth Phase)"(hereinafter referred to as the"National Sixth Standard for Light Vehicles"),which announced the sixth Emission requirements and implementation time for light vehicles.
In recent years,China’s motor vehicle pollutant emission standards have gradually increased.In 2001,the national first-phase motor vehicle emission standards began to be implemented.After 15 years of development,the national fourth-phase emission standards are currently implemented nationwide,and the key regions are implemented in the fifth phase.Standards,reducing emissions of bicycles by more than 90%,effectively promoting technological upgrading in the automotive industry.In order to further strengthen the prevention and control of motor vehicle pollution,reduce emissions from the source,and implement the requirements of the"13th Five-Year Plan for National Economic and Social Development"related to"implementing national VI emission standards and corresponding oil standards",the Ministry of Environmental Protection,The General Administration of Quality Supervision,Inspection and Quarantine of the People's Republic of China has issued the National Sixth Standard for Light Vehicles.
国The national six emission standards for light vehicles have changed the previous method of equivalently transforming European emission standards.The automotive industry is invited to participate in the preparation of the entire process,and fully absorb the opinions and suggestions of experts,scholars and the business community.The compilation team carried out a large number of investigations and studies,analyzed and aggregated emission data of 8,600 national five vehicle models,investigated the mileage of 500,000 light vehicles,and designed and conducted verification tests.The significance of the National Sixth Standard for Light Vehicles is reflected in the following:first,it has changed from following European and American motor vehicle emission standards to bold innovations,and for the first time achieved the establishment of world-leading standards;Second,in the context of China's excess automotive production capacity,it can play a role in eliminating backward production capacity and leading industrial upgrading;third,it can meet the requirements of key regions to tighten automotive emission standards in order to accelerate the improvement of ambient air quality.
The six national standards for light-duty vehicles have six breakthroughs in technical content.The first is to adopt a unified global light-duty vehicle testing procedure,which has comprehensively tightened testing requirements,effectively reducing the gap between laboratory-certified emissions and actual-use emissions,and reducing fuel consumption and emissions.The second is the introduction of actual driving emission test(RDE),which improves the vehicle's emission control level under actual use,facilitates supervision,and can effectively prevent cheating behaviors in which actual emissions exceed the standard.The third is the use of fuel neutrality.,No more loose limits are set for nitrogen oxides of diesel cars and particulates of gasoline cars;the fourth is to comprehensively strengthen the control of VOCs emissions,introduce 48-hour evaporative emission test and VOCs emission test during the refueling process to improve the level of evaporative emission control More than 90%.The fifth is to improve the requirements of vehicle diagnostic systems,increase the storage requirements of permanent fault codes,and prevent tampering measures to effectively prevent vehicles from exceeding the standards during use.Sixth,simplify the rules and determination methods of environmental protection consistency and compliance monitoring and inspection in use by competent authorities to make operations more implementable.
In order to ensure that the automotive industry has sufficient preparation cycles for relevant vehicle model and power system changes and upgrades,as well as model opening and production preparations,the country’s sixth national standard for light vehicles adopts a step-by-step implementation method,with two national emissions a and six national emissions The limit plan will be implemented in 2020 and 2023,respectively.At the same time,key areas with special needs for atmospheric environmental management can implement National Six emission limits in advance.At present,the industry's production and oil conditions for the implementation of the standard have also been initially met.A number of light-duty automobile manufacturers have basically completed the development of prototypes that meet the national standards for light-duty vehicles.The General Administration of Quality Supervision,Inspection and Quarantine and Standardization of the People's Republic of China has also approved the issuance of national standards for automobile gasoline and diesel oil for the sixth phase.
In the next step,the Ministry of Environmental Protection will actively coordinate relevant departments to effectively guarantee the implementation of the National Sixth Standard for Light Vehicles,further increase the supervision and inspection of environmental protection standards for motor vehicles,promote the upgrading of vehicle oil products,and effectively improve the air quality of cities.
