GPF: THE PARTICULATE FILTER FOR PETROLS

In the GPF the material used for the filtering system is cordierite (AIMg), while the DPF is made of silicon carbide (Sic). This difference is due to the fact that cordierite better resists to high temperatures, which direct injection petrols reach much faster than diesels (this is also the reason why they pollute more, as also highlighted in the Transport & Environment study).
