Here's the "normal" values for all of the Aftertreatment Parameters during a Parked Regen. *Note* On a DD13, there are 3 important parameters that will have higher values than the DD15 or DD16. -Turbo Speed 38,000-42,000 rpm. -SCR Inlet NOx Sensor 400-500 ppm. -Actual DEF Dosing Quantity 900-1100 g/h.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 ...a Diesel Oxidation Catalyst (DOC). Together, those products are effective at removing 99 percent of PM soot from the exhaust system using wall-flow substrates. As soot accumulates in the filter, a regeneration event will provide sufficient heat to oxidize the captured soot. The remaining ash is removed during regularly scheduled cleaningDuring regen the temp doesn't get over 305. I thought it had to hit over 500 to kick on injector 7. ...

Fan cycles.CM871 High DOC temp during regen - tariqzai - 04-12-2020. Hi everyone, I have regen issue with my 2009 Volvo with CM871. During Regen instead of DOC temp staying steady and DFP temps going up, this engine shows DPF outlet temp staying steady while DPF intake and DOC temps keep going up (1000+). I have this truck for 3 years and every forced ... Since these high temperatures generally fo not occur during normal engine operation, a number of strategies are used to actively increase the exhaust temperature [4]. Active regeneration systems may include the use of a diesel burner to directly heat the exhaust entering the DPF or the use of a diesel oxidation catalyst (DOC) to oxidize diesel ...This fault sets when the DOC inlet temperature does not reach a minimum of 270°C (518°F) during a regeneration. Monitored Parameter: DOC Inlet Temperature Typical Enabling: Conditions Engine running, regeneration active: Monitor Sequence None: Execution Frequency Always: Typical Duration None: Dash Lamps MIL, CEL: Engine Reaction None

I have a Detroit dd13 that when I put it through a Regen, the temp spikes to over 1500 degrees and sets a code 3246/0. It also has EGR slow response code 3058/9. The temps would climb normally until the system got to about 700 degrees and that's the when dpf outlet temps would just speed past the dog inlet temps.My unit starts the regen but the DOC inlet temp is only getting to 420 degrees and is not allowing to burn off for the regen. I’m getting codes 4752, (intake manifold pressure sensor) 3719, 3711. Will the intake manifold …Symptoms of a clogged DPF filter are excessive regens and long regens, last ing 60 minutes or longer. You can monitor temperatures/pressures when doing a forced regen to make sure everything is in range and working properly. Faulty … ….

Excessive idling does cause the DPF to need a regen more often. The Pete I was in, it was recommended that if we had to idle due to temps, that we raise the idle to 1500 to help keep the DPF hot enough to regen itself. However, with the other issues you said it has, sounds like it needs to see Mr. Peterbilt.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. haiti colonialism Had a forced Regen done and off I went. 150 miles later the same code came back again. so I ignored it for another 250 miles and then second alert saying Air Intake system problem. Had a second Regen done and noticed Inlet manifold pressure was very high but as the regen was going on this issue reduced to normal levels. ralley housemikeywilliamswhat is the paleozoic era Jun 19, 2016 · Fengjun Yan.
