In which year did China's National V vehicle emission standards come into effect?

China's National V emission standards, officially known as the Fifth Stage National Motor Vehicle Emission Standards, were implemented nationwide starting from January 1, 2017. Below is relevant information about emission standards: National V: The Fifth Stage National Motor Vehicle Pollutant Emission Standards, referred to as "National V standards," feature emission control levels equivalent to Europe's currently implemented Euro 5 standards. The European Union has enforced these since 2009, imposing stricter limits on vehicle emissions such as nitrogen oxides (NOx), hydrocarbons (HC), carbon monoxide (CO), and particulate matter (PM). Each upgrade from National I to National IV reduced single-vehicle pollution by 30% to 50%. Comparison with National IV: The new standards reduce NOx emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles. Taking Shanghai's annual vehicle registration volume of approximately 350,000 units as an example, the annual NOx emissions from new vehicles are expected to decrease by about 1,000 tons. Additionally, China's National V standards match the emission control levels of Europe's currently implemented Euro 5 standards.
As a long-time driving enthusiast, I remember the China V emission standard was implemented nationwide starting from January 2017, especially for light-duty vehicles like sedans and SUVs. Back then, I had just changed my car and specifically researched the update, finding that the new standard aimed to reduce exhaust pollution by requiring lower emissions of nitrogen oxides and particulate matter. In comparison, the previous China IV vehicles had weaker exhaust control, which could easily affect air quality. Nowadays, China V compliant vehicles are common, with convenient maintenance and readily available parts. When buying a car, it's advisable to prioritize this standard—not only is it environmentally friendly, but it also offers benefits in terms of annual inspections and insurance. I believe such policies that drive technological upgrades are beneficial, making our city air cleaner and driving more reassuring. In the long run, supporting higher emission standards means protecting the health of future generations, which is something worth everyone's attention.
Environmental protection has always been a concern of mine. The China V emission standard was fully implemented in 2017 with the goal of reducing the environmental harm caused by vehicle pollutants. I remember when air pollution was severe, especially the heavy smog in big cities. After the standard was introduced, vehicle exhaust emission data showed significant improvement. It set stricter limits for both gasoline and diesel vehicles, mandating the installation of purification devices. Now when I drive, I notice the air quality on the roads has improved. However, this standard was just the beginning, as the China VI standard followed soon after. I recommend everyone choose vehicles that meet at least the China V standard when buying a car. Not only does this contribute to emission reduction, but it also saves fuel and money in daily driving, with more stable maintenance. Such policies benefit everyone, and we should all actively respond to them.
From a technical perspective, the China 5 emission standard was implemented in 2017, primarily targeting improvements in engine and catalytic systems to enhance emission efficiency. The standard requires vehicles to reduce emissions of nitrogen oxides, carbon monoxide, and other pollutants, with gasoline vehicles utilizing three-way catalytic converters to improve purification effectiveness. Daily driving experiences remain largely unchanged, but vehicle repairs benefit from better parts compatibility, eliminating the need for additional adjustments required by older models. Both fuel consumption and performance are indirectly affected by the standard. When purchasing new vehicles, prioritizing China 5 models is advisable, as they tend to maintain more stable residual values in the used car market. Although the China 6 standard is now in effect, China 5 laid a solid foundation. It's recommended that car owners familiarize themselves with these details.
