What is the comparison between Euro 5 and China 6 standards?
2 Answers
Euro 5 and China 6 standards are compared as follows: 1. In terms of exhaust emissions: The Euro 5 emission standard is equivalent to the China 5 emission standard, which is less stringent than the China 6 emission standard. The China 6 emission standard is more stringent and will become one of the strictest standards globally. 2. In terms of emission limits: Compared to the China 5 emission standard, the China 6a phase emission standard for gasoline vehicles tightens the carbon monoxide limit by 30%; the China 6b phase emission standard for gasoline vehicles tightens the carbon monoxide and nitrogen oxide limits by 50% and 42%, respectively. Compared to China 5, the China 6 emission limits will be tightened by approximately 40% to 50%.
I've just researched vehicle emissions and found significant differences between Euro 5 and China 6 standards. Euro 5, being a European standard, has relatively lenient limits on nitrogen oxides and particulate matter - for instance, allowing emissions up to 0.18 grams per kilometer. It's more suitable for older engine designs, but pollution issues remain noticeable, especially during traffic congestion when exhaust fumes are heavy. China 6, developed by China, imposes much stricter requirements - reducing nitrogen oxides to below 0.06 grams per kilometer and adding real-world driving tests to ensure cleaner emissions during actual road use. I always say this represents an environmental upgrade that can reduce urban smog and respiratory diseases. Driving newer vehicles noticeably improves air quality, lowering health risks for everyone. While it might seem like a small matter, the cumulative effect makes a substantial contribution to society.
