The lifespan of a diesel particulate filter varies based on the application. Vehicles operating at low speeds on short journeys are unable to meet the requirements for the filter to clean itself.ĭPFs can also fail due to poor servicing.
Oftentimes, blocked diesel particulate filters are caused by short journeys at low speeds. What Are the Symptoms of a Blocked Diesel Particulate Filter? Prevents harmful exhaust emission and the black smoke you commonly see emitted from diesel vehicles when accelerating.Įngine manufacturers use DPFs to trap particulate matter in order to meet the EPA 2007 emission standards. The regeneration process burns off excess soot deposited in the filter, which In order to reduce emissions from diesel vehicles, diesel particulate filters capture and store exhaust soot, which must be periodically burned off to regenerate the filter. A DPF typically uses a substrate made of a ceramic material that is formed into a honeycomb structure. If you’ve been exposed to the world of diesel, you have probably wondered, “What is DPF?”Ī diesel particulate filter, or DPF, is an exhaust aftertreatment device that traps particulate matter such as soot and ash.
Failing to maintain these filters can lead to significant (and costly) consequences for the vehicle.įollow along as we share what diesel particulate filters are, signs of a blocked filter, types of regeneration and more. Whether you own a diesel-powered vehicle or aspire to become a diesel technician, it’s important to understandĭiesel particulate filters and how they work.ĭiesel particulate filters play a critical role in the functioning of diesel-fuel cars and trucks.
