What are China III and China IV Vehicles?

[JamesonAnn]

China III and China IV vehicles refer to the automobile exhaust emission standards, corresponding to the policy standard named 'Limits and Measurement Methods for Emissions from Light-Duty Vehicles (China Phase II, III, IV)'. Below is an introduction to the emission standards: 1. Introduction to Emission Standards: Emission standards regulate the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot emitted from vehicle exhaust. These standards are established to prevent environmental pollution caused by exhaust from compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. 2. Technical Measures: To stably meet the vehicle emission standards, vehicles must be equipped with technical measures that ensure pollutant emissions comply with the national standards, and they must use fuel that meets the standards.
