Active regeneration system. In an active regeneration system, a burner and air compressor are used to bring the system back to its clean state. The exact period of regeneration can be determined by calculating the backpressure of the exhaust gases. When the backpressure of the exhaust gases reaches 10,000 Pa, regeneration will be …13. Inspect the DOC inlet pressure sensor electrical connector for corrosion and spread pins. a. If corrosion or damaged (or bent) pins are found, repair as necessary. Verify repairs. b. If no corrosion or damage is found, replace the DOC inlet pressure sensor. Refer to section "Removal of the GHG14 Diesel Oxidation Catalyst Inlet Temperature ...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. 28. Using DiagnosticLink, monitor DOC inlet pressure while performing a parked regeneration. Refer to section "Performing a Parked Regeneration - GHG17". Does the DOC inlet pressure start out high and stay high? a.DOC face plugging, or DOC sulfur poisoning due to not using Ultra Low Sulfur Diesel (ULSD) fuel. Therefore, the AFI tip should be cleaned and the DOC inlet should be inspected before replacing the AFI. Follow the procedures in Guided Diagnostics to inspect and clean the DOC. Service Regeneration Once the soot level reaches 170%, the engine is ...Example : SCR Outlet temp (587°C) 1090°F minus SCR Inlet Temp (398°C) 749°F = (116°C) ... (2.32 psi) and dropped to 5kPa (0.72 psi) during a full regen. 13. Is the DOC inlet pressure starting above the pressure specified below and stays high? 2 Symptom Diagnostics: Noisy 1- Box Aftertreatment 6 All information subject to change without notice.Tue 11/28. 90° /76°. 65%. Times of clouds and sun with a couple of showers. RealFeel® 98°. RealFeel Shade™ 95°. Max UV Index 5 Moderate. Wind ENE 2 mph.If the system doesn't reach this then something is wrong with engine, not the DOC or injector. If the temps reach 525 or better and the inlet temp to the DPF stalls around 800 or is very very slow to reach 1000+ then something is wrong with the injector or DOC. Monitor these parameters during a regen, and you should have these values;Soot load was level 5. performed a parked regen. DOC inlet temp was bias. ... Mack MP8 regen issues.

Presuming you are using DDDL? You should see the dpf inlet, the catalyst, the outlet. You want the inlet to show 400, the filter inlet at 450 and above, and the outlet at 450 and above for when the doser will open up and start heating the catalyst up more.Once the DOC is heated up, it can produce high-effic7. Start the engine and run a Parked Regen. M 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. Right away I noticed that the DOC inlet temperature The stage1 is before regeneration phase. The DOC inlet temperature, the DPF inlet temperature, and the DPF outlet temperature are sequentially lowered due to the heat loss. The stage2 is during regeneration phase. The DOC inlet temperature slightly reduces due to the vaporization heat of methanol.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 ... Yellow (Solid or Flashing) to indicate the need to regenera
Ran an onboard filter cleanliness test to get the regen temps. Soot load was at 44%. Doc intake temp is 775 to 800. Dpf inlet is 1150 to 1185. Dpf outlet is 1220 to 1270. TC1TOP IS 1.5. EGR position is 35%. International is telling me its not eligible for the crankcase filter update, last 8 of vin: EL771725.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.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 (750°F). What is doc outlet temperature? The DOC inlet temperature should be greater than 400°C (750°F). Ambient temperature will have a large impact on DOC inlet …temperature sensor). This phase will occur during all of the selected sub tests. AHI dosing will occur whether or not the AHI subtest is selected in order to meet target DOC outlet temperature (measured by the T2 temperature sensor) and SCR average temperatures and bring the NOx sensors online faster. Operation failure during Heating EATS phase: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 …

Based on the dropped to idle (DTI) test, a test method is developed to determine the safe regeneration temperature of the DPF. The results show that when the ... The results showed that engine-out NOₓ emissio Jan 18, 2020 · 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. Ask the driver if a parked REGEN was attempted and what was the r11. After the low temp ATD regeneration has run for 20 minutes, monStart the engine and run a Parked Regen. Monitor Die temperature from inlet temperature to outlet temp erature. The THC from post injection is assumed to be completely combusted inside the DOC (Chen, P . et al. (2014)). Face plugging is an extreme buildup of carbon on the inlet side a. If the DOC inlet pressure starts out above 10 kPa (1.45 psi) and decreases during a parked regen, this indicates that the DPFs were plugged and the parked regen has cleared them. Go to step 8. b. If the DOC inlet pressure starts above the pressure specified below and stays high, the DOC is considered plugged. Go to step 9. Table 1. Emissions ...
