What does it mean when the vehicle's particulate filter is regenerating?

[Luis]

If the driving conditions are not met and the vehicle cannot automatically initiate the regeneration process for an extended period, the dashboard will display a "Particulate Filter Requires Regeneration" warning. Here is the relevant information: 1. Function of the Particulate Filter: To meet stringent emission standards, most China VI-compliant vehicles are equipped with a particulate filter. The particulate filter effectively captures fine particles from exhaust emissions, benefiting both the environment and the vehicle. Diesel vehicles require periodic cleaning of the particulate filter, whereas gasoline vehicles do not. 2. Working Principle of the Particulate Filter: After capturing soot particles, the particulate filter burns these particles when the exhaust temperature is high. By controlling the intake air and fuel injection within the engine cylinders, the temperature inside the particulate filter is increased, allowing the carbon particles to react with oxygen and combust. This process regenerates the filter by completely burning the soot particles at high temperatures. Without a particulate filter, these particles would be directly emitted into the atmosphere, causing air pollution.
