An automobile benchmark
Peugeot's particle filter (PF), launched in 2000 as a world first on the 607, reduces soot particle emissions from diesel engines by 99%.
Today this technology that is incorporated into most of Peugeot's engines complements the advantages of HDI technology and helps protect the environment.
A self-cleaning filter
During the first phase soot particles are retained in a porous-structured, silicon carbide filter.
Then during the regeneration phase these particles are burnt off at very high temperatures, after the vehicle has run for several hundred kilometres.
This process is automatic and perfectly imperceptible.
