Do they have a DPF like the '11 and newer do that will do a regen ... Doc inlet and dpf inlet/outlet temps. An actual code would help, but ...- Observe exhaust gas temperatures from DOC Outlet Temp, DOC Inlet Temp and DPF Outlet Temp. - Refer to Aftertreatment Diagnostic Manual Supplement for information regarding OBFCT. 4. If OBFCT runs successfully, go to Step 7. 5. If OBFCT aborts, replay OBFCT using Service Maxx and observe Aftertreatment temperatures and diagnostic trouble codes.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.An increased pressure drop was also recorded across the DOC during active regeneration (ΔP C), which could be attributed to fouling of the catalyst inlet face by soot and/or coke species. No increased DOC pressure drop was seen during filter loading. Figure 16. Pressure drop and temperature during active regeneration (600°C)

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,Yes; Go to step 14. b. No; Refer to section "Unable to Start a Parked Regeneration". 14. Using DiagnosticLink, monitor DOC inlet temperature. Does the ...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. If the DOC inlet pressure starts out high above 10 kPa (1.45 psi) and decreases during the parked regen, thisStationary Regeneration Test that is performed using JPRO® or OEM Service Tool once either or both of the. components are exposed to coolant. During regeneration, the coolant evaporate out of both components due to the high temperatures that are attained, and thus the components return to normal operating specications.Monitor smoke control status during regen. Smoke control status should be 0. DOC Inlet Temperature Sensor non-responsive Monitor DOC inlet temperature. No temperature change after engine startup indicates sensor problem.

The current version works for 2011-2013 trucks. The one for 2014+ trucks is still under development and should be released by next month.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 …After it stopped my truck requested another park regen. If you’re needing that many regens, you may need a new filter or perhaps a sensor. You should go see your truck manufacturer. I should add that 200° is normal temp for your dash to show. Mine goes up to about 225° before the fan kicks in and brings it back down to 200°. ….

Remove EGR and cleaned, no exhaust leaks. Engine temp 200 drg. Fan cycles.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 regen i did was successful and most of the time DPF differential pressure would be zero after the regen.If your psi sensor is cleared and your temps still don’t come up, you’ll need to pull the DPF’s back out and Blow or out the DOC’s. Remove the 1-box inlet and rig a good vacuum cleaner to or all that soot will settle in front of the DOC and plug at least part of them again!

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 ...The catalyst should also exhibit low light-off temperature, to enable active regeneration during periods of operation with lower engine load. Figure 4 illustrates the light-off performance with post injection of fuel and exhaust injection of fuel for a fresh and aged DOC. The x-axis represents the inlet temperature of the DOC.
