What is the difference between China VI and China V?
3 Answers
The difference between China VI and China V lies in the fact that China VI vehicles use a more efficient three-way catalytic converter, enabling the engine's exhaust emissions to meet the China VI standard. Below are the relevant details about the China VI and China V automotive emission standards: 1. China VI standard emission limits: China VI A: Carbon monoxide 700mg/km, Non-methane hydrocarbons 68mg/km, Nitrogen oxides 60mg/km, PM fine particles 4.5mg/km, etc.; China VI B: Carbon monoxide 500mg/km, Non-methane hydrocarbons 35mg/km, Nitrogen oxides 35mg/km, PM fine particles 3mg/km, etc. 2. China V standard emission limits: The carbon monoxide emission per kilometer driven must not exceed 1000 milligrams; The non-methane hydrocarbons emission per kilometer driven must not exceed 68 milligrams; The nitrogen oxides emission per kilometer driven must not exceed 60 milligrams; The PM fine particles emission per kilometer driven must not exceed 4.5 milligrams.
As a car enthusiast, I often pay attention to changes in emission standards. The main differences between China 5 and China 6 standards lie in stricter emission limits and testing methods. China 6 imposes much lower limits on nitrogen oxides and particulate matter compared to China 5, with nitrogen oxide emission limits reduced by over 40%. More importantly, China 6 introduces real-world driving tests, requiring vehicles to meet standards under actual driving conditions, unlike China 5 which mainly relied on laboratory testing. This means vehicle control systems need to be more precise, effectively reducing actual pollutant emissions. Additionally, China 6 strengthens control over evaporative emissions, reducing harmful odors. In daily driving, I find China 6-compliant vehicles more helpful in improving urban air quality, though they may lead to slightly higher car prices for buyers. In the long run, choosing China 6 vehicles is more environmentally friendly and helps avoid traffic restriction issues.
I remember being torn between China 5 and China 6 models when buying a car last year. The China 6 vehicles were several thousand yuan more expensive, but in major cities like Beijing and Shanghai, it's easier to get license plates because some local regulations restrict China 5 vehicles. In terms of emission differences, China 6 has more precise exhaust control, reducing pollutants by 30% and significantly decreasing air pollution. Additionally, China 6 requires an upgraded OBD system that can instantly monitor emission faults. If buying a used car, China 5 might be cheaper, but it could affect resale value and vehicle inspections. My suggestion is to opt for China 6 when buying a new car, as it aligns better with current environmental policies and offers more convenience in use. Overall, this relates to urban living quality and the air we all breathe, making it worth the extra investment in eco-friendly technology.
