Vehicle fails to regen. During High idle regen, DOC outlet max 479 F , Command boost pressure 0%, fuel doser inject ... DOC inlet temp doesn't go past 495 degrees. DOC stops around 515 and DPF temp is at 495. Checked for exhaust leaks = none f ...CM871 High DOC temp during regen. 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 regen i …NOTE: Normal DOC pressure is less than 10 kPa (1.5 psi) for a 1-Box™ emissions package and 13 kPa (1.9 psi) for a Two-Box option. 38. Using DiagnosticLink, monitor DOC inlet pressure while performing a parked regeneration. Refer to section "Performing a Parked Regeneration Using DiagnosticLink® Standard". Does the DOC inlet pressure start ...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 ...

After cleaning the doc it was reinstalled on the truck, reset doc/dpf counters. Performed manual stationary regen, the truck kicks up to 1200-1300 to start regen, the turbo speed starts at around 42k and turbo actuator 92%, egr valve position consistently stays at 0%, exhaust gas pressure about 140, intake manifold pressure about 12.5.Here are some of the data I wrote down during the parked regen: DPF DIFFERENTIAL PRESSURE: 0.1hg AFTERTREATMENT FUEL PRESSURE: 14.4psi …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,If the DOC inlet pressure starts out high above 10 kPa (1.45 psi) and decreases during the parked regen., this indicates the DPFs were plugged and the parked regen cleared them. If the DOC inlet pressure starts above 6 kPa (GHG14, 0.8 psi), and stays high, the DOC is considered plugged.1 NUMBER: 2 ATS 07 S.M.

PARAMETER, VALUE. Coolant Temperature, Above 140*F. DOC Inlet Temperature, 600-725*F. DOC Outlet Temperature, 1050-1150*F. DPF Outlet Temperature ...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. ….

The functionality of aftertreatment DOC and aftertreatment DPF can be regained using the Aftertreatment DPF. Stationary 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 DOC inlet 500-600F DPF inlet starts to increase once regen starts. DPF outlet will increase after DPF inlet starts building temp and heat transfers through DPF. DPF outlet may peak slightly above inlet temp but should down below the inlet temp. …

a. If the DOC inlet pressure starts out high above 10 kPa (1.45 psi) and decreases during the parked regen, this indicates the DPFs were plugged and the parked regen cleared them. Go to step 10. b. If the DOC inlet pressure starts above 6 kPa (0.8psi), and stays high, the DOC is considered plugged. Go to step 11. 3 09-15 All information subject ... Save. ClickClick5 · #9 · Aug 7, 2015. EGT3 is the one you will want to watch for the regen. This is the post DPF temp probe. EGT2 is post DOC, and EGT1 is pre DOC. Normal driving, EGT3 will reach around 500-800F. You will know …Was given log file from last completed regen on the truck 10 days earlier. Comparing the 2, boost pressure and doc inlet pressure is slightly lower throughout regen. dpf out temp reaches above 1200 but doc out temp is above 1000 as well. Will upload if someone wants to compare

lviv program Start the engine and run a Parked Regen. Monitor Diesel Oxidation Catalyst (DOC) inlet pressure and engine speed during the regen. NOTICE: If DOC inlet pressure is 19.9 kPa (2.9 psi) or higher at any time during the parked regen, immediately stop the regen because turbocharger damage may occur and Go to step 18. osrs mystic fire stafftypes of business dress codes Oct 26, 2018 · Engine Speed 1100 rpm (1275 rpm during first 12 minutes of regen then 1100 rpm for fuelmap ending in ZGS 999) Turbo Speed 45,000 – 60,000 (turbo is used to create pressure in the DD13 and DD15AT only) Fuel Cut Off Valve 100% (once DOC inlet temp reaches 536° F) Engine Torque Around 5% Actual Torque Load 15 – 18% (greater than 20% may ... During a proper regen, DOC inlet temp, or temp #1, should be about 550-600. DOC outlet temp, or temp #2, should be 1000-1200 degrees. DPF outlet temp should be 950 to 1200. In a healthy system, the engine injects fuel into the exhaust during a regen that the DOC burns to create the heat. The heat is used to BAKE down the collected soot in the DPF. reagan cooper volleyball Aug 23, 2011 · During a proper regen, DOC inlet temp, or temp #1, should be about 550-600.
