[Boromir]

China VI vehicle emission standard includes: 1. Carbon monoxide content is 500 milligrams per kilometer; 2. Nitrogen oxides content is 35 milligrams; 3. Particulate matter content is 3 milligrams; 4. Non-methane hydrocarbons content is 35 milligrams. Emission standards refer to the levels of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot emitted from vehicle exhaust. The vehicle emission standard is established to prevent pollution from the exhaust of compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. Vehicle emission standards are categorized into: 1. Vehicles with a total mass less than or equal to 3.5 tons equipped with spark-ignition or compression-ignition engines; 2. Vehicles with a total mass greater than 3.5 tons equipped with spark-ignition engines; 3. Vehicles with a total mass greater than 3.5 tons equipped with compression-ignition engines.
