Also, is the DOC and DPF due for cleaning? It sounds like you have access to Insite. When running a regen you need to open up data monitor and watch all the exhaust temps and doser injector state. Once a regen is initiated the DOC inlet and DPF inlet need to reach about 525 -550 degrees.The influence of far post injection in cylinder or downstream injection in the exhaust pipe on the DOC inlet temperature can be negligible (Chen, P. et al. (2014 ... Kim, Y. W., Van Nieuwstadt, M., Stewart, G., & Pekar, J. . Model Predictive Control of DOC Temperature during DPF Regeneration, SAE Technical Paper, No. 2014-01 ...Malfunctioning temperature sensors. 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. Hey Nick, I got a 2014 KW T800 with a paccar mx13.

Nov 13, 2014 · During a parked regen on a DD15, the SCR Inlet NOx sensor should be around 200-300ppm. DD13 SCR Inlet NOx sensor is slightly higher around 400-500ppm. The SCR Outlet NOx should be somewhere in the neighborhood of 5-25ppm for all DD Platforms. The other true method in testing the NOx sensors is to perform a regular parked regen, then perform ... 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 ...13) Monitor DOC inlet temperature. It MUST be greater than 400°C (750°F). If it is not above 400°C (750°F), block off part of the radiator with cardboard. Be careful that coolant temperatures do not go high enough to cause a Check Engine ight.l 14) Continue to monitor the DOC inlet temperature to make sure it is greater than 400°C (750°F).Decided the doc inlet temp sensor should be replaced and the DOC/DPF be sent out for cleaning. They didn't look to bad after I took them out the the cleaning test said they needed to be cleaned. Reassembled everything and did another parked regen. DPF outlet temp stayed about 50F above inlet temp during the entire regen.

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.I have a 2017 Mack/CHU. With an engine light on.

A typical mid-efficiency boiler or water heater operated with water temperatures in the range of 130° to 140° will prevent condensate problems. Note: A water heater must use a thermostatic mixing valve to provide lower-temperature domestic water in order to prevent a risk of scald injury. This has proven to provide reliable temperatures ...Regen Temperature- Out Of Range Low Table 1. SPN 3556 /FMI 1 Description This code sets when the exhaust temperature does not increase above the modeled threshold when a regeneration is enabled. Monitored Parameter DOC outlet temperature sensor Typical Enabling Conditions Regeneration enabled, 1100 to 2050 rpm, 50% to 100% engine load.

During testing, temperature of exhaust gas can become 1500°F (800 °C) and the temperature of exhaust system surface can cross 1300°F (700°C). These temperatures are hot enough for igniting or melting common materials, and can also lead to serious personal injury. Even after the vehicle has stopped moving,May 5, 2021 · Introduction. During the thermal regeneration process of the diesel particulate filter (DPF), the exhaust temperature at the DPF inlet needs to be heated up to above 500 °C to oxidize the accumulated soot particles in an efficient way [1], [2], [3].

Based on the DOC light-off temperature achieved, the in-cylinder post fuel injection along with further modulation of the air system parameters can be used to reach a sufficiently high inlet gas temperature for the DPF ... How to Reduce DPF Regens. Stiction is the sticky friction caused by byproducts of burnt oil. High pressure builds heat in tight-tolerance applications and extreme heat causes the oil to burn, oxidize and create layers of sludge and deposits. Fuel injectors, pistons, rings, and a variety of other engine components are continually susceptible to ...
