lv represents the China IV emission standard. Below is relevant information about the China IV emission standard: 1. Introduction to China IV emission standard: lv represents the China IV emission standard. The main pollutants emitted by vehicles include hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter. By applying technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, the emission of these pollutants is controlled and reduced to below specified levels. 2. Methods to distinguish vehicle emission standards: (1) Check the vehicle's environmental protection label. (2) Query on the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center. (3) Check the vehicle's factory certificate. (4) Make a rough judgment based on the year the vehicle was registered. (5) Take the vehicle registration certificate to the vehicle management office for inquiry.
My friend often asks me about car emission standards, such as what 'National Emission Standard' means. Generally, in China, car emission standards are classified into National I, National II, up to National VI, with different years of vehicles corresponding to different standards. For example, most new cars after 2017 are National V or National VI. To find out the specific emission level of a car model, you can check the vehicle registration certificate or the environmental label, or enter the VIN code in an online query system. The emission level affects the car's price and environmental performance, with lower-standard cars facing more restrictions in cities. In recent years, the trend has been towards stricter standards, with National VI becoming the mainstream. This helps reduce pollution but also increases costs for car manufacturers. When buying a car, it's advisable to pay more attention to emission data, not just focusing on saving fuel costs, but also considering the long-term impact.
