What does DPF overload mean?

[DelManuel]

DPF overload refers to the situation where the emission of pollutants exceeds the standard. DPF, or Diesel Particulate Filter, is a device installed in the exhaust system of diesel vehicles to reduce particulate matter in the exhaust through filtration. The Diesel Particulate Filter (DPF) captures particles using a combination of surface and internal filtration mechanisms, such as diffusion deposition, inertial deposition, or linear interception. There are two scenarios when the DPF light comes on in a vehicle: 1. Automatic Regeneration: The DPF light appears green, and the vehicle maintains normal driving conditions at 80 km/h. Once the particulate matter is processed, the DPF indicator light will automatically turn off. 2. Manual Regeneration: The DPF yellow indicator light will flash, typically when the vehicle is driven at speeds below 80 km/h. Press the DPF control button, and the yellow indicator light will remain steadily lit. The process takes approximately 15 to 30 minutes, and once the particulate matter is processed, the indicator light will automatically turn off.
