Where is the Diesel Particulate Filter Located?

[MacAndrew]

Particulate filters are ceramic filters installed in the exhaust system of diesel engines. Here is relevant information about particulate filters: 1. Particulate filters can reduce soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation; 2. Diesel particulate filters can effectively reduce particulate emissions by first capturing particulate matter in the exhaust gas and then oxidizing the captured particles to regenerate the filter. The 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 the back pressure of the engine, leading to a decline in engine performance. Therefore, it is necessary to periodically remove the deposited particulate matter to restore the filtering performance of the DPF.
