What is a Diesel Particulate Filter?
The diesel particulate filter (DPF) is a component developed to meet emissions standards.November 30, 2022
DPF has started to be applied in newly produced cars. In diesel vehicles, this filter is intended to be designed and used to cause less harm to nature and humanity. Since the only exit point of the vehicles is the exhaust, the DPF combines with the exhaust to provide an exit from the same point and minimizes bad gas emissions.
This filter, which is similar in structure to a honeycomb, traps solid particles harmful to the environment in the exhaust. However, the level of these particles trapped in the** filter** after it increases over time and can lead to reasons such as clogging. Pressure sensors measure the level of soot residue in the diesel particulate filter and when the critical soot level is detected in the filter and the appropriate conditions are met, the regeneration process begins.
What is the Function of a Diesel Particulate Filter?
There are numerous honeycomb-like pores inside the particle filter. Since the release of this fuel, which is not fully burned in the vehicle, is harmful, the particulate filter takes this unburned fuel into it.
All the exhaust gases pass through these pores. While the burned gases from the exhaust are filtered, the same cannot be said for non-combustible fuels. Excess fuels stick to this filter. Thus, the natural balance is preserved.
In some cases, the vehicle cannot perform the regeneration process and the soot level will prevent the engine from operating efficiently. In this case, the DPF mark may appear on the display. When this warning is seen, the vehicle should be used at a constant speed and high speed for a certain time. In automatic vehicles, this can be done by moving the gear lever to the manual position. As the vehicle starts to be used at high revs, the engine management system sends more fuel and increases the exhaust temperature. When the exhaust temperature reaches approximately 600 °C, the regeneration process begins, and the solid particles are burned and turned into soot. In some cases, this process may not work either. In such a case, the vehicle should be taken to the service, and the regeneration process should be performed with the help of a fault detection device.
Generally, the DPF clogs for the following reasons:
- Low-quality fuel,
- Long-term use of vehicles at low speed and in stop-and-go traffic,
- Running the vehicle at idle for a long time,
- Use of oil of the wrong specification.
The DPF, which is present in all newly released diesel vehicles, may become unable to be cleaned even with the regeneration process and may need to be replaced if the necessary precautions are not taken.
