1. Check the frame number or engine number on the website: when buying a new car, there will be a frame number or engine number on the car. You can check the information of this car on the Internet, and you can know whether this car belongs to National Five or National Six.
2. Check the car certificate: there will be a column on the car certificate that says the emission standard, and it will clearly indicate whether the car belongs to the fifth or sixth country. The national five emission standard symbol is V, and the national six emission standard symbol is VI.
3. Look at the car environmental protection list: When buying a car, there will be an environmental protection list, which will clearly indicate whether the car belongs to National Five or National Six.
4. Check the vehicle certificate: By reading the information in a series of numbers, you can know whether the vehicle belongs to the fifth country or the sixth country. In the column of 3C certification of exhaust emissions, there will be a series of decimal points, and there will be a number after the decimal point, representing whether the car is national five or national six.
Six Breakthroughs in Technical Content of National Six Standards for Light Vehicles
First, the globally unified light vehicle test procedure was adopted, which tightened the test requirements in an all-round way, effectively narrowed the gap between laboratory certified emissions and actual use emissions, and laid the foundation for coordinated control of fuel consumption and emissions.
Secondly, the introduction of RDE improves the emission control level of vehicles in actual use, which is beneficial to supervision and can effectively prevent cheating in actual emission exceeding the standard.
The third is to adopt the principle of fuel neutrality, and no longer set loose limits for diesel NOx and gasoline particulate matter.
Fourth, strengthen the control of VOCs emission in an all-round way, introduce 48-hour evaporative emission test and VOCs emission test during refueling, and raise the control level of evaporative emission to over 90%.
The fifth is to improve the requirements of vehicle diagnosis system, increase the storage requirements of permanent fault codes and tamper-proof measures, and effectively prevent vehicles from exceeding the standard emission during use.
The sixth is to simplify the rules and judgment methods of the competent department for supervision and inspection of environmental compliance and in-use compliance, so as to make the operation more feasible.
