What is China VL?
3 Answers
China VL refers to the China VI emission standard, which mainly pertains to vehicle exhaust emission standards. Here is a detailed introduction to the China VI emission standard: Classification: The China VI emission standard is divided into China VIa and China VIb. According to relevant national regulations, starting from July 1, 2020, all light-duty vehicles sold and registered must comply with the China VIa emission limits. From July 1, 2023, all light-duty vehicles sold and registered must meet the China VIb emission limits. Reasons for implementing the China VI emission standard: The China VI emission standard is more aligned with China's actual national conditions. The China VIb standard reduces carbon monoxide emissions by half compared to the China V standard, and the emission limits for carbon oxides have been reduced by approximately half. The early implementation of the China VI standard also significantly contributes to environmental improvement.
China V is the fifth-stage emission standard in China. As someone who has been driving for many years, I pay close attention to these regulations. Introduced in 2013, it imposes stricter requirements on vehicle pollutant emissions, such as significantly lower limits for carbon monoxide and nitrogen oxides compared to China IV. When buying a used car, I always check this standard because vehicles below China V may face restrictions like driving bans or license plate limitations in cities like Beijing, Shanghai, and Guangzhou, which can affect daily commutes. Many gas stations now promote China V fuel to help reduce vehicle pollution. Since the implementation of China V, air quality has indeed improved, especially in big cities, making it quite practical for environmental protection. However, with the promotion of China VI, China V vehicles may soon become outdated, so it's important to stay updated on policy changes. Remember, China I is the oldest standard, starting in 2000, and China V is considered an intermediate transitional phase. It's advisable for car owners to check their vehicle's nameplate to confirm the emission level.
As maintenance professionals, we often encounter vehicles that need to be upgraded to China V standards. China V represents the fifth generation of Chinese emission regulations, requiring new vehicles to reduce hydrocarbon and particulate emissions upon leaving the factory. In actual repair work, vehicles are fitted with new three-way catalytic converters or OBD systems to meet the standards, otherwise, they won’t pass the annual inspection. After China V became mandatory in 2017, many older vehicles were phased out, increasing workload and service charges. I recall during the transition from China IV to China V, vehicle owners complained about rising costs, but the technological improvements made engines more environmentally friendly. Now, with China VI in place, a similar pattern continues. The evolution of emission standards has progressed step by step from China I, and understanding this helps in better diagnosing and maintaining vehicles.
