What does DPF automatic regeneration mean?

[TeaganMarie]

DPF stands for Diesel Particulate Filter, and DPF regeneration means the diesel particulate filter is in operation. The following is an introduction to the knowledge of diesel particulate filters: 1. Function: The diesel particulate filter can effectively reduce the emission of particulate matter. It first captures the particulate matter in the exhaust gas 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 gradual increase of particulate matter in the filter will cause an increase in engine back pressure, leading to a decline in engine performance. 2. Working process: The diesel particulate filter DPF captures particles through a filtration device that combines surface and internal mixing, such as diffusion sedimentation, inertial sedimentation, or linear interception.
