What does DPF regeneration mean?

[MacLeah]

When a certain value is reached, it will lead to a decline in engine performance such as power and fuel economy. The following are the methods of DPF regeneration: 1. Regeneration method one: Monitor the exhaust back pressure through a differential pressure sensor. When the back pressure rises to a certain value, the captured particles are burned into CO2 and discharged. 3. Regeneration method three: Use electric heating in the particulate filter to create high temperature, burning the captured particles into CO2 and discharging them. 4. Regeneration method four: Add additives to the fuel to lower the combustion temperature of particles, allowing the captured particles to burn into CO2 and be discharged at a lower temperature.
