Diesel Particulate Filter

A diesel particulate filter (DPF) is located in the exhaust system of your diesel vehicle and is designed to remove soot and diesel exhaust matter from your exhaust. It has a series of small, honeycomb-shaped openings covered in palladium or platinum. These openings trap soot on the channel walls and prevent it from exiting the exhaust tail pipe. A DPF helps with reducing NOx emissions and soot when operating. Short trips often cause excessive soot, which can clog your diesel particulate filter more quickly than highway driving. It is recommended to clean your DPF regularly to avoid blockages in your exhaust system. When your DPF is blocked, it may trigger a dashboard warning light. You can sometimes regenerate your DPF by driving it on the road for 10-15 minutes at 40 miles per hour. The soot in the filter usually burns off after this amount of time. If your dashboard warning light remains on, you might need to replace your DPF. At O'Reilly Auto Parts, we have diesel particulate filters available for select models. Keep your diesel emissions at the proper levels with a replacement diesel particulate filter for your vehicle.
