Jun 5, 2008 路 The exhaust filter is the diesel particulate filter after the cat, it stops diesel soot in itself, when the pressure differential and temperature get to a certain point it's the ecm's job to decide a time to do a regeneration, adding diesel fuel at the exhaust stroke to raise dpf exhaust temps and burn off the soot, sometimes it takes 20 or 30
Such DPF filters are devices that reduce toxic emissions (air pollution) from diesel exhaust. Specifically, these filters prevent solid particles that are harmful to breathe (i.e. soot), which are created by burning fuel, from leaving the truck and getting into the air. They also keep an engine more fuel-efficient by recycling the soot that Feb 23, 2022 路 A diesel particulate filter (or DPF for short) is part of a diesel car 's exhaust system that's designed to filter out harmful soot. Diesel engines produce a lot of soot when they burn fuel. This soot is what's known as particulate matter. It鈥檚 a very fine substance that can cause serious health problems, namely breathing problems.Mar 5, 2019 路 Exhaust filter full ? I am new to the forum. I just got a 2018 Ram 2500 with 6.7, it has 40,000 miles. I was coming home from work and it said 70 percent full starting regen,went to 90 percent and then to full contact dealer ,all within a mile of driving. Also it set the check engine light. It was 25 degrees .
