What is the national emission standard for LV?
3 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.
I remember the salesperson mentioning China V emission standards when I changed my car last year. It's China's fifth-stage vehicle emission standard, implemented nationwide since 2017 mainly to reduce pollutant emissions like nitrogen oxides and PM2.5, which is much stricter than the older China IV standard. As an ordinary car owner, I find this policy quite practical – cleaner exhaust makes vehicles more environmentally friendly and helps avoid urban driving restrictions. When buying a car, check the vehicle certificate or the environmental label on the door to confirm it meets China V standards. By the way, China VI standards are already out now, so always ask about policy updates when purchasing to prevent emission issues from affecting resale value. Also pay attention to exhaust system maintenance, and regular annual inspections ensure compliance.
After years in auto repair, I've encountered many car owners asking about the classification of China V emission standards. It represents the fifth-generation national emission standard, with significantly higher technical requirements than the previous China IV. New components like DPF particulate filters were added to exhaust systems. Post China V implementation, if abnormal fault codes appear in new vehicles, it may indicate non-compliance. I advise owners against cutting corners with substandard parts—always use professionals for oil or filter changes to avoid emission issues affecting annual inspections. Ultimately, this standard drives technological progress, reduces air pollution, improves urban air quality, and delivers substantial public health benefits.
