Diesel Particulate Filter (DPF) – The diesel particulate filter is installed in the exhaust systems of diesel engines (empyema, diesel). The DPF filter cleans the exhaust gases from soot and ash particles. The DPF filter allows you to eliminate the emission of black smoke, characteristic of diesel engines.

We assemble, regenerate and remove the DPF

The filter has the form of a spatial structure with a very large total surface area of the walls. Soot particles settle on porous walls or fibres made of metal, ceramics or special paper (disposable filters only). The efficiency of a properly functioning filter ranges from 85% to 100%, which means that no more than 15% of the original solid-phase pollutant content is released into the atmosphere.

DPF Solutions and Regeneration

Soot particles accumulating in the filter cause gradual clogging and loss of efficiency. Some vehicles use disposable filters that require replacement when the filter is full. A more advanced solution is the self-cleaning filter consisting of the catalytic combustion of soot after the filter reaches a sufficiently high temperature (soot burns at a temperature higher than 600 degrees Celsius). This system is called passive regeneration.

Active systems are also used to burn off the soot accumulated in the filter – for example, periodic change of the engine’s operating mode, as a result of which it emits increased amounts of nitrogen dioxide, which, flowing through the filter, causes oxidation of the accumulated soot. Another way to actively regenerate the filter is to periodically heat it with an additional flame of the mixture injected into the filter, as a result of which the soot is burned.

Among the solid particles, there is also ash coming from, among others, oil, fuel additives, or products of wear and corrosion of engines. Ash, unlike soot, is not burned to gaseous form in the regeneration process, thus accumulating in the diesel particulate filter. For this reason, over time, the degree of filling the filter irreversibly increases and the periods between regeneration processes decrease. When the filter reaches a critical level of ash filling, which does not allow its reduction by the regeneration process, the onboard computer signals an error in the exhaust gas treatment system and it is necessary to replace or mechanically regenerate the filter outside the vehicle.
