WARNING!!: ⚠️⚠️⚠️Always use the proper tools and safety equipment to perform this job. Failure to perform the job correctly can result in personal injury or ...In active DPF systems, HCs are introduced into the exhaust gas (via engine post-injection or exhaust injection) and oxidized over the DOC in order to increase the DPF inlet temperature. This functionality is typically combined with NO 2 generation for passive DPF regeneration.You can tell by watching your temperatures during a regen. If your DPF intake is lower then your DPF outlet, and theyre both above 800F, it's called 'inverted temps'which indicate your DOC ...more ...Catalyst (DOC), a chemical reaction occurs, and the exhaust system temperature increases to a level that oxidizes the soot in the filter.

If regen is starting in the software (i mean it showing that regen is started and rpm goes up) and your doc inlet temp is not raising more than 380-480 then dosing will not start. Dosing starts after the doc inlet being heated up to 560+. This initial heating depends from turbocharger and intake throttle valve.AlanJ Discussion starter · Mar 10, 2020. While trying to get my head around OBD Fusion and what all the PID data represents, I was able to capture a regen in process. What I had expected to find was when the 'soot %' reached 100%, the regen would start and that's exactly what happened. What I didn't expect was what happened to the EGT reading.…
