DPF is an abbreviation for Diesel Particulate Filter in English, and its Chinese name is Particle Filter. It is a device specifically used in diesel vehicle after treatment to capture and adsorb carbide particles. It can effectively purify 70% to 90% of the particles in the exhaust. Based on this, some people believe that DPF is a miracle tool for reducing particulate matter, which can be installed on any car once and for all. However, is this miracle tool really that powerful? The answer is negative.
Because diesel vehicle particulate matter comes from incomplete combustion, in order to solve the problem of particulate matter, the combustion strategy of China IV V emissions is oxygen enriched complete combustion. The consequence of this is a significant reduction in particulate matter emissions, but an increase in nitrogen oxides. Therefore, China IV V often adopts SCR selective catalytic reduction as a post-treatment method.
Nevertheless, diesel vehicles still produce particulate matter under certain operating conditions, and DPF can play its role by adsorbing these particles to make the exhaust cleaner.
