Rußpartikelfilter
Rußpartikelfilter, often abbreviated as DPF, is a device installed in the exhaust system of diesel engines to reduce particulate matter emissions. These filters are designed to capture soot and other fine particles that are a byproduct of diesel combustion. The DPF works by physically trapping these particles as they pass through a ceramic or metallic filter structure.
Over time, the trapped soot accumulates and can block the filter, leading to increased exhaust backpressure.
The introduction of DPFs has been a significant factor in meeting increasingly stringent emissions regulations for
