What is the China National Emission Standard for VI?

[Ariel]

VI refers to the China National VI Emission Standard. The key specifications of the China National VI Emission Standard include: 1. Carbon monoxide content limited to 500 milligrams per kilometer; 2. Particulate matter (PM) content capped at 3 milligrams; 3. Nitrogen oxides (NOx) restricted to 35 milligrams; 4. Non-methane hydrocarbons (NMHC) limited to 35 milligrams. The full name of China National VI is 'China's Sixth Stage Emission Standards for Light-Duty Vehicles', which regulates the emission limits of harmful gases such as carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), particulate matter (PM), and soot from vehicle exhaust. This standard is established to prevent environmental pollution caused by exhaust emissions from compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health.
