Oct 5, 2021 · The DPF system is a honeycomb filter, similar to a traditional catalytic converter, that captures and collects particulate soot. The 6.7 Cummins has had a DPF system since halfway through the 2007 model year. 2007.5-2012 models had a completely separate DPF system that sat behind the DOC system. In 2013+ models the DOC and DPF were integrated ... 7. Start the engine and run a Parked Regen. Monitor DOC inlet pressure and engine speed during the regen. Compare your DOC inlet pressure reading to the screen shots below to identify a possible cause of the fault code. a.

2022年2月16日 ... An engine oil consumption problem will be hard on a DPF. As Otto explained, the additives in engine oil cannot be oxidized away during a regen, ...What temp should doc inlet be during regen? Engine rpm should then become stable around 1275 rpm. 13) Monitor DOC inlet temperature. It MUST be greater than 400°C (750°F). What is doc outlet temperature? The DOC inlet temperature should be greater than 400°C (750°F). Ambient temperature will have a large impact on DOC inlet …Right away I noticed that the DOC inlet temperature reading was at 662 F (default max value as I found out) @ 1.7V, yet the outlet temperature was 419 F @ 1V . These thermo-couples run on 5V and generally have a much larger spread between temperature/voltage correlation. Now it was time to let the data talk. ….

Review the last seven minutes of the parked regeneration log file; was the SCR inlet temperature more than 38°C (68.4°F) lower than SCR outlet temperature? a. Yes; Go to step 23. b. No; replace the ATD. For a One-box system, replace the DOC/SCR module. For a Two-box system, replace the SCR module.The T2 sensor, at the DOC outlet, provides feedbacks for closed loop controls. A fast response control system ensures the DOC outlet temperature stays on target while engine operations vary considerably. To verify the tight DPF inlet temperature control, an active regeneration was enabled during a NRTC test. The results are shown in Figure 8 ...
