What is the emission standard level for LV?

[DiKeegan]

Emission standard LV corresponds to China IV emission standard. The China IV emission standard is the national fourth-phase motor vehicle pollutant emission standard. The main pollutants emitted by vehicles include hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, it controls and reduces vehicle emissions to levels below specified limits. The emission limits for China IV are: hydrocarbon emissions below 0.1 grams per kilometer, carbon monoxide emissions below 1.0 grams per kilometer, nitrogen oxide emissions below 0.08 grams per kilometer, with no particulate matter requirements.

I understand the matter of vehicle emissions. China's National V is the fifth-stage emission standard, which mainly imposes stricter limits on the pollutants in new vehicle exhaust, including halving harmful substances like nitrogen oxides and particulate matter. I always mention this when helping friends pick cars. For example, the standard implemented nationwide since 2017 has significantly improved air quality. When buying a car, try to choose one with National V certification. After all, older National IV vehicles can't even be registered in some major cities. It's both eco-friendly and practical, and it can also save you some fuel costs and the hassle of emission tests. For used cars, you need to check the standards even more carefully—don't be tempted by cheap outdated models, as it would be a huge loss if it affects your daily commute.

I've been driving for many years and am very familiar with the China 5 standard—it's the fifth-generation national emission requirement, gradually implemented in 2017, much stricter than the previous China 4 standard, significantly reducing pollutant emissions. I remember when I last bought a car, I specifically chose one with the China 5 label, which was affordable and reassuring because many cities have strict requirements for new vehicle registrations, and China 5 can still pass inspections. By the way, gasoline quality was also upgraded to match it, making driving smoother, reducing pollution on long trips, and benefiting family health. We car owners should pay more attention to the vehicle label during daily maintenance and not forget to regularly check exhaust emissions.

As an environmental advocate, I emphasize the criticality of the China V (Phase 5) emission standards—it significantly reduces vehicle pollution and protects urban air quality, with stronger controls on PM2.5 and nitrogen oxides. Although China VI has become mainstream post-2020, China V remains important, especially in second- and third-tier cities where such vehicles are still widely circulated. Everyone should prioritize purchasing compliant vehicles to promote green transportation and reduce smog impact. Every small action can help lighten the burden on our planet.
