dgiturbo. No guys, it works. If you watch it carefully, it goes up to about 15% but then does a regen and cleans back to zero. It does this very often, so most times you check the gauge it is at zero, but you may occasionally catch it during regen. For some reason, RAM/Cummins isn't playing when it comes to the DPF. Diesel Particulate Filter The diesel particulate filter traps soot from the exhaust to lower particulate emissions. During certain driving conditions the engine will perform a regeneration cycle, which will use additional fuel injections and the catalyst to heat up the exhaust temperatures to the point where the soot will be burnt out and form ash. damage you cannot see inside the diesel particulate filter (DPF) core. Please inspect the core using the visual inspection process outlined below. 1. Core must be like-for-like, and in as removed condition 2. Core that has been attempted to be cleaned in-field since removal from vehicle will not be accepted 3. Visually inspect the core housing. Detroit ® will not cover damages resulting from use of a non-authorized DPF cleaning process. DPF Maintenance Intervals for EPA 07. DPF cleaning intervals are established for each engine platform.

Because of these sensors, if you delete the DPF or do a DPF bypass without a rewrite of the engine management computer, it will set the check engine light and the car may not run correctly. In one case, a DPF delete before the replacement ECU flash melted the reflector because of the excess fuel during an attempted regen cycle. Abstract: The accumulation of ash in diesel particulate filters is an important factor limiting the filter’s service life, increasing its pressure drop and having an adverse effect on fuel economy. The main sources of ash are engine lube oil additives, as well as fuels and engine wear and corrosion. A number of studies have been conducted and Two part mix, don't recall if it was the same product but it came in regular cans not for use with sprayer. Spray the first part, let it sit, spray the second part, let it sit. Then I used a pressure washer to clean it out. Could not believe the crap that came out. Welded it back up and it seems to be working like new. The DOC and DPF are filters that work together. First, the exhaust is sent to the DOC, where it is chemically altered. Then, the exhaust gases move through the DPF, which is able to trap and hold any soot and ash that remain. As you can see, this system is designed to catch ash and particulates before they’re released, thereby helping to make quires an occasional Diesel Particulate Filter (DPF) cleaning. Under normal driving conditions, the DPF cleaning occurs without any driving involvement. However, there may be circumstances that require a service regeneration to be performed. DPF SOOT LEVEL Beginning with 2017 Silverado and Sierra models, the DPF Soot Accumulation is measured in Also the OCR only shows up when it is in park. It won't show up at 100% if you are driving. I use the OCR if the filter is at 100% and i don't have a highway trip planned that will complete a full regen. That way I don't drive it just to complete a regen and put the extra miles on it.
