Jun 20, 2023. #2. The more you're aware of your active regens the longer the DPF, especially, should last. Some here have said ignore the perameters and let the cars ability to work around an incomplete regeneration and just do its thing. Those people no longer seem to exist. During active DPF regeneration, the exhaust temperature elevates to around 500 degrees C. These temperatures allow for the oxidation of soot, which in turn cleans the filter. Unlike automatic regeneration, which is commanded by the control module, manual regeneration, or parked regeneration, is commanded by the operator. Diesel particle filters give owners of diesel vehicles lots of problems - often expensive, time-consuming and inconvenient ones. There's a lot of misinformat Normally the DPF is 'self-generating' in that it does not require any specific maintenance. However, the DPF can become clogged if the vehicle is only driven for short distances all the time - this may result in a costly visit to the workshop. This is from Australia 2013-2 Supplement to the Owner's Manual, p16: 'If the vehicle is mostly driven To manually regenerate your Ram EcoDiesel engine, start by driving at highway speed for at least 15 minutes. This will allow the filter to reach a certain temperature. Then, turn off the engine and wait five minutes before restarting it. Once you have restarted the engine, go back to highway speed and monitor your dashboard for any warning Passive Regeneration Passive regeneration occurs when exhaust gas temperature is elevated above 300°C (575° F). These temperatures may be reached when the engine is under heavy load. Service Regeneration Service regeneration is performed with the Tech 2, and is used to clean a soot loaded filter during a dealership service visit. 16 regeneration minutes /3,600 = .00444 = 4/10s of 1% of engine time is consumed during parked regeneration. Fuel cost for sixteen minute parked regeneration @ 2,200 rpm ~~$1.00. Diesel Particulate Filter supersedes tractor muffler. At some point in time DPF needs to be replaced. FtAI.
