Diesel Particulate Filter (DPF) Regeneration. If you mainly do 30km a day of city driving (avg 30-40 km/h), how often a week do you need to do the DPF Regeneration cycles ? How long does a normal Regeneration cycle take? - i.e. How long on the freeway do you need to drive for 1 cycle? Thanks If the DPF does not get clogged by ash from oil, then why do they require the use of low ash oil? 08 2500 6.7L G56 4x4 QC LB, Edge Juice (w/Att), Firestone Airbags, 2" Level Lift, DPF substrate removed, 4 H&S fooler boxes, EGR blocked, muffler delete, dent in fender from a bison, LT285/75-17 Toyo ATs It’s important to deal with this quickly, or the pressure buildup can crack the DPF. Common indicators of a clogged DPF filter are unusually frequent forced regens and unusually long ones. A standard forced regen is under 40 minutes; if yours typically last for an hour or more, this may indicate an issue. A Blocked DOC (170) The right way to care for your vehicle's DPF Read in this article: Explaining Diesel Particulate Filters and How They Work What is DPF Regeneration and How Does A DPF Cleaner According to Koukal, this form of regeneration typically occurs in vehicles with a high duty cycle, such as long-haul trucks. Active regeneration If the aftertreatment system does not reach 1,112 degrees F, the engine control module (ECM) on the vehicle will activate an active regeneration cycle, Just explains. How Long Do DPFs and DOCs Last? A well-maintained, properly cleaned or new DPF and DOC should remain effective for generally five to 10 years, or 10,000 or more hours of operation. Engine problems with fuel control or oil consumption may quickly deteriorate performance and lead to the need for replacement parts sooner. The 2nd to last regen I had was on a 700+ mile highway run. The regen happened at about 500 miles which I didn't understand at the time because it only read 67 DPF load. As I understand it Ford built in a 500 mile regen maximum, so that is why I saw one start at 67 DPF load. Just kinda wondering if others see about the same or what. I have a 2018 Ford Transit DCiV two-litre. Even 80mph is only about 2000 rpm in 6th gear. Now a DPF requires, as I understand it, a decent flow of gas at a decent temperature to maintain a healthy state. So, given that this engine gets along very nicely at legal highway speeds at such low revs, how does one ensure a trouble free life from the DPF? Diesel particle filters give owners of diesel vehicles lots of problems - often expensive, time-consuming and inconvenient ones. There's a lot of misinformat Duramax Hard Parts. LML.
