Are diesel particulate filters required?
Beginning with the 2007 model year, 100 percent of the on-road diesel HDEs required the use of a diesel particulate filter and 50 percent of the engines require NOx exhaust control technology; beginning with the 2010 model year, 100 percent of the on-road heavy-duty diesel engines require NOx exhaust control technology …
When were diesel particulate filters required?
2007
In 2007, particulate filters were introduced on all medium- and heavy-duty engines in the North American market (USA & Canada), on applications ranging from diesel pick-up trucks to Class 8 tractors. An estimated 2,000,000 DPF-equipped engines were manufactured over the 2007-2010 period [2247] .
When did DPF filters become mandatory?
2009
Since 2009 diesel particulate filters (DPFs) have been compulsory in new diesel cars. But, particularly for cars driven in cities, the DPFs can become clogged and cause breakdowns.
Is it illegal to remove DPF?
While it’s not illegal to remove a car’s DPF, it is illegal to drive without it if one should be fitted. The process for removing a DPF is a relatively simple one that requires cutting a hole in a vehicle’s exhaust, removing the filter and welding the resultant hole shut.
When do I need to clean my diesel particulate filter?
Diesel cars and trucks manufactured after 2009 must have a DPF. The drawback to all of this is that the DPF needs to be cleaned regularly. The soot particles attach themselves to the lining of the DPF while the engine is running.
How does the Diesel Particulate Filter ( DPF ) work?
Think of it as a catalytic converter that traps and oxidizes particulates in the exhaust. But, the DPF regenerates in intervals rather than all the time like those found on gasoline vehicles. The Diesel Particulate Filter (DPF) is a ceramic brick with tiny passages that do two things. First, they trap the particulates or soot in the exhaust.
When did Ford start using the diesel particulate filter?
Starting in 2008, Ford began using Diesel Particulate Filters (DPF) on their diesel trucks. The DPF, is responsible for eliminating particulate matter from the exhaust system, specifically the soot that is emitted by diesel engines.
How does the particulate filter clean the exhaust?
At the same time, the filter is slowly clogging with the very particulates that it’s designed to remove from the exhaust. This process of cleaning the DPF is done through a process called regeneration. There are several different methods used by various manufacturers to clean the DPF.
