What is the China V Emission Standard?
2 Answers
China V Emission Standard is the fifth stage national standard for motor vehicle pollutant emissions, also known as "China V Standard". The emission control level of China V Standard is equivalent to the European Union's Euro 5 emission standard currently in implementation. It imposes more stringent restrictions on motor vehicle emissions such as nitrogen oxides (NOx), hydrocarbons (HC), carbon monoxide (CO), and particulate matter (PM). From China I to China VI, each upgrade in standard reduces vehicle pollution by 30% to 50%. Compared to China IV Standard, China V Standard can reduce nitrogen oxide emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles.
As a driver who has long been concerned about environmental protection, I am well aware that the China 5 emission standard is the fifth-phase light-duty vehicle pollutant control measure mandatorily implemented by the country in 2017. It strictly limits harmful gases such as carbon monoxide, nitrogen oxides, and particulate matter emitted by vehicles to lower levels, similar to Europe's Euro 5 standard. For example, the nitrogen oxide limit was reduced from 0.08 grams per kilometer under China 4 to 0.06 grams, significantly improving urban air quality and reducing smog and respiratory issues. By improving fuel quality and installing catalytic converters, China 5 vehicles operate more cleanly and efficiently. This standard greatly benefits health, especially making outdoor activities safer for children, while also driving automakers to innovate in energy-saving technologies. When using a China 5 vehicle, I've experienced emissions being halved, easier annual vehicle inspections, and long-term reductions in greenhouse gas emissions, supporting global environmental protection.
