[LaBrynlee]

VI is the China VI emission standard, fully known as the National Sixth Stage Emission Standard for Motor Vehicle Pollutants. It specifies the limits for harmful gases emitted from vehicle exhaust, including carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot. This standard is established to prevent environmental pollution from the exhaust of compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. The China VI emission standard includes the following requirements: 1. Carbon monoxide content is limited to 500 milligrams per kilometer; 2. Particulate matter content is limited to 3 milligrams; 3. Nitrogen oxides content is limited to 35 milligrams; 4. Non-methane hydrocarbons content is limited to 35 milligrams.
