What is the national emission standard for LV?
1 Answers
LV corresponds to the National IV emission standard. Below is an introduction to the National IV emission standard: 1. The National IV emission standard is the fourth stage of China's national standards for motor vehicle pollutant emissions. 2. The main pollutants emitted by vehicles include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter). 3. The standard aims to control and reduce vehicle emissions to levels below specified limits. Related information: 1. The National V vehicle emission standard is equivalent to the Euro 5 standard in the EU. The EU began implementing this standard in 2009, imposing stricter limits on vehicle emissions such as hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter. From National I to National V, each upgrade in the standard reduces single-vehicle pollutant emissions by 30% to 50%. 2. Compared to the National V standard, the National VI emission standard is more stringent in terms of testing standards and pollutant emissions. The test cycle has been changed from NEDC to WLTC, with the addition of real-world driving emission tests. The pollutant limits are stricter, with National VI being approximately 40% to 50% more stringent than National V. The limits for CO and HC are about one-third stricter than those of National V.
