Start the engine; using DiagnosticLink start the NOx Sensor ...gmmerlin · #2 · Jun 23, 2007. NO, during the regen process, extra fuel is sent to the DOC (converter) which causes it to heat up. The hot exhaust gases from the DOC are sent to the DPF for the regen. So all the heat is going to be from the DOC back. There are EGT sensors pre and post DPF to monitor the temp.Passive regeneration typically occurs when the temperature of the aftertreatment DPF is above 3160C [601 OF]. This occurs during highway driving or driving with heavy loads. Since passive regeneration occurs naturally, it is considered to be normal engine operation. No fuel is added to the exhaust stream during passive regeneration.Volvo D13 regeneration. we have couple of trucks on our fleet with the same problem.

Didn't set any faults and it brought the soot level down however the NOX readings were never displayed. DPF temps however were not good as the outlet temp remained higher than the inlet temp during the entire regen. Good indication that the DOC is face plugged and I'll recommend the DOC/DPF be sent out for cleaning.After cleaning the doc it was reinstalled on the truck, reset doc/dpf counters.

During cold-start and other low exhaust temperature conditions such as idle and low load, higher NO x conversion can be achieved if thermal management strategies are implemented to increase ...Mack MP8 regen issues. 2012 CXU613 with 2012 fault codes so it's not a 2013. Truck arrived at the shop at the beginning of the week. Soot load was level 5. performed a parked regen. DOC inlet temp was bias. DPF outlet temp stayed above inlet temp during regen.To create the thermal conditions necessary for soot regeneration in the CSF, fuel was injected into the exhaust pipe up-stream of the DOC (Fig.2). In this study the conditions for fuel injection were fixed to 25ml/min, 300°C inlet temperature and 49,000/hr space velocity for the DOC to generate a CSF inlet temperature of 600C.Results show that at high DOC inlet temperatures (>190 °C), the DMDF mode combined with DOC achieves the high DPF inlet temperatures and the high NO 2 /PM ratio, which is benefit for passive regeneration.

The temperature sensors, spread through the aftertreatment system, measure the exhaust going into and out of each filter. The first sensor is in the DOC and the last is after the SCR. The sensor’s readings measure how well the system is working, and a faulty sensor can interfere with the regen process. Hi Mike.
