What does DPF regeneration mean?

[VanTyler]

DPF stands for Diesel Particulate Filter, which is a device installed in the exhaust system of diesel vehicles to reduce particulate matter in the exhaust through filtration. Here is relevant information: 1. Function: The diesel particulate filter can effectively reduce the emission of particulate matter. It first captures the particulate matter in the exhaust and then oxidizes the captured particles to regenerate the particulate filter. The so-called regeneration of the filter refers to the fact that during long-term operation of the DPF, the accumulation of particulate matter in the filter will gradually increase, causing an increase in engine backpressure and leading to a decline in engine performance. 2. Working process: The diesel particulate filter DPF captures particles through a combination of surface and internal filtration mechanisms, such as diffusion deposition, inertial deposition, or linear interception.
