How does a DPF work?

Diesel Particulate Filters are a type of emissions aftertreatment device which trap soot particles from the engine exhaust preventing them from reaching the environment.

Unlike a catalytic converter which is designed to reduce gas-phase emissions flowing through the catalyst, the particulate filter traps and retains the solid particles until the particles can be oxidised or burnt in the DPF itself, through a process called regeneration.
