How to distinguish between National Five
As environmental protection standards become increasingly stringent, the National V emission standards have become an important reference indicator for the current vehicle market. For consumers, how to accurately determine whether a vehicle meets the National Five standards is crucial. This article will combine the hot topics and hot content on the Internet in the past 10 days to give you a detailed introduction to the definition, identification methods and related data comparison of the National Five Standards.
1. What are the National Five Standards?
The National V standards refer to the national fifth-stage motor vehicle pollutant emission standards, whose full name is "Light Vehicle Pollutant Emission Limits and Measurement Methods (China's Fifth Stage)". The standard was implemented nationwide in 2017 and aims to reduce environmental pollution caused by motor vehicle exhaust emissions. The National Five standards put forward more stringent requirements for the emission limits of carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx) and particulate matter (PM).
2. How to tell whether a vehicle meets the National Five standards?
The following are several common identification methods:
| method | Specific operations |
|---|---|
| Check the vehicle environmental label | There is an environmental protection sign on the front windshield of the vehicle, and the mark "National V" or "National 5" refers to the National Five standard. |
| Check vehicle certificate of conformity | The emission standard is clearly marked on the certificate, and you can check whether it is "GB18352.5-2013" (National V standard code). |
| Check vehicle VIN number | Check the emission standards on the "Motor Vehicle Environmental Protection Network" or the official website of the car company through the vehicle identification number (VIN code). |
| Check the vehicle’s factory date | Light-duty gasoline vehicles produced after January 1, 2017, and heavy-duty diesel vehicles produced after January 1, 2018, must comply with National V standards. |
3. Comparison between National V and National IV emission standards
The following are the main differences between China V and China IV emission standards:
| pollutants | National IV limit value (g/km) | National V limit value (g/km) | Decrease |
|---|---|---|---|
| Carbon monoxide (CO) | 1.00 | 1.00 | 0% |
| Hydrocarbons (HC) | 0.10 | 0.068 | 32% |
| Nitrogen oxides (NOx) | 0.08 | 0.06 | 25% |
| Particulate matter (PM) | 0.025 | 0.0045 | 82% |
4. Market status of National V vehicles
According to hot data analysis in the past 10 days, National V vehicles still account for a relatively high proportion in the second-hand car market, but some cities have begun to restrict the transfer of National V vehicles. The following is a comparison of policies in some popular cities:
| city | National V vehicle transfer policy | Implementation time |
|---|---|---|
| Beijing | It is prohibited for foreign vehicles from Category V to enter | January 1, 2020 |
| Shanghai | To allow the transfer of National V vehicles, they must meet the Shanghai license conditions | January 1, 2023 |
| Guangzhou | Allowing National V vehicles to transfer in | No restrictions yet |
| Shenzhen | It is prohibited for foreign vehicles from Category V to enter | July 1, 2022 |
5. Things to note when purchasing National V vehicles
1.Check vehicle information: Ensure that the vehicle environmental protection label and certificate of conformity are consistent with the actual vehicle.
2.Pay attention to local policies: Some cities have restricted the registration or transfer of National Five vehicles. You need to check local regulations in advance.
3.Check vehicle condition: Most National V vehicles are produced after 2017, and key components such as engines and exhaust gas treatment systems need to be inspected.
Summary
The key to distinguishing National V vehicles is to check the environmental protection mark, certificate of conformity and VIN code. With the popularization of National VI standards, the market value of National V vehicles may gradually decrease, but their environmental performance is still better than that of National IV and below standards. Consumers should make reasonable choices based on their own needs and local policies when purchasing.
