Technical Information Up to and including Euro 4 Diesel Particulate Filters (DPF) Diesel vehicles have become increasingly popular across the world as diesel engine technology continues to advance due to their superior fuel economy over petrol vehicles. The drawback with diesel vehicles however, is that they have high NOx and particulate emissions compared to their petrol counterparts. In response to this, existing Euro Emissions Standards were tightened and greater environmentally friendly initiatives were developed, such as the implementation of "Stop/Start" technology in many modern vehicles. One of the most prominent developments however was the introduction of Diesel Particulate Filters (DPFs). What are they and how do they work? The Diesel Particulate Filter is part of the exhaust system which functions to remove particulate matter (soot) from the exhaust gasses. It does this by capturing, containing and converting these soot particulates into Carbon Dioxide via a process of Regeneration. Exhaust gasses containing soot enter the DPF channels which are closed off at alternating ends. The channel walls are porous, allowing exhaust gasses to pass through whilst retaining and trapping the soot particles in the DPF as the gasses are forced through. Clean exhaust gasses then exit the DPF and trapped soot particles are eliminated during the Regeneration cycles to prevent blockages and therefore, prevent the DPF’s function from being affected. The Engine Management System (ECU) constantly monitors the filter’s performance and will carry out this Regeneration as necessary. What are they made from?
Regeneration As the DPF acts as a “soot trap”, it has to be able to clean itself to prevent it becoming blocked and affecting the running of the vehicle. This is the process of Regeneration. There are 3 different types of Regeneration – Passive, Active and Forced. Regeneration “burns off” (oxidises) the particulates that have accumulated in the DPF.
WARNING! The very high temperatures applied during Active and Forced Regeneration can lead to an accumulation of ash and aging. The build-up of ash is treated by physical intervention such as chemical cleaning, ultrasonic cleaning or replacement of the DPF. Cross references
