What is the emission standard for LV?

[StDerek]

LV refers to the China IV emission standard, which is the fourth stage of national motor vehicle pollutant emission standards. The main pollutants emitted by vehicles include hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, the standard aims to control and reduce vehicle emissions to below specified levels. The China III and China IV standards are based on the Euro 3 and Euro 4 vehicle emission standards. Compared to China II, China III further reduces pollutant emission limits. The exhaust pollutant emission limits under China III are 30% lower than those under China II, while China IV will further reduce them by 60%. To ensure that vehicles stably meet emission limit requirements during use and maintain the durability of emission control performance, additional requirements for on-board diagnostic systems and in-use vehicle compliance have been introduced.
