How does a Diesel Particulate Filter work?

24/08/2022 0 Comments

A Diesel Particulate Filter collects particulate matter in the exhaust stream by means of physical filtration.

Soot particles from diesel exhausts are trapped by a porous ceramic substrate inside the filter and collected on the walls.

When the maximum ‘fill level’ is reached one of several methods is employed to clear the filter of the collected particulates.

It is only necessary to replace the DPF when this process breaks down and the filter becomes irreversibly clogged.
