What are the exhaust emission standards for diesel vehicles?

[GeorgeLynn]

Carbon monoxide must not exceed 2.2g/km; hydrocarbons must not exceed 1.13g/km; particulate matter standards for diesel vehicles must not exceed 0.18g/km; durability requirements are set at 50,000 km. The main pollutants emitted by vehicles include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter). Below are the requirements of the China VI emission standards: 1. China VI standards: The China VI standards are extremely high, ranking among the strictest vehicle emission standards globally. Compared to the China V emission regulations, China VI adds limits for nitrous oxide and particulate matter particle numbers, and requires a 50% reduction in carbon monoxide content during cold start conditions, a 30% reduction in hydrocarbon content, and a 30% reduction in carbon monoxide content. 2. Post-implementation of China VI standards, China V vehicles can still be driven: Even after the implementation of China VI standards, China V vehicles can still be driven on the road, though registration and licensing may become more difficult. For those China V vehicles in stock, they will definitely be sold at discounted prices, and the closer the implementation date of China VI, the cheaper they will become.
