When was China V discontinued?
1 Answers
China V vehicles stopped being registered in June 2019. Below are specific details about China V vehicles: 1. China V standards: The National Fifth Stage Motor Vehicle Pollutant Emission Standard, known as "China V Standard," has emission control levels equivalent to Europe's fifth-stage emission standard currently in effect. The European Union began implementing this standard in 2009, imposing stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. Each upgrade from China I to China IV reduced single-vehicle pollution by 30% to 50%. 2. Changes in China V gasoline standards: To further enhance vehicle exhaust purification systems and reduce vehicle pollutant emissions, the sulfur content limit was reduced from 50ppm in the fourth stage to 10ppm, an 80% reduction; considering the potential health risks of manganese and its adverse effects on vehicle emission control systems, the manganese content limit was reduced from 8mg/L in the fourth stage to 2mg/L, prohibiting the artificial addition of manganese-containing additives; to address the reduction in octane number caused by sulfur reduction and manganese prohibition in China V gasoline, and the shortage of high-octane resources in China, the gasoline grades were adjusted from 90, 93, and 97 to 89, 92, and 95, respectively, with the addition of 98-grade gasoline requirements in the standard appendix.
