Start looking at it, doc temps run up to 700 degrees within the first 5 minutes but I never see any pressure kick up from the Hydrocarbon doser. By 10 minute mark all temperatures holding steady around the 400-500 mark. Checked intake/exhaust leaks, intake throttle valve, egr valve, ensure all items are were they should be during the regen process.Oct 5, 2021 · The DPF system is a honeycomb filter, similar to a traditional catalytic converter, that captures and collects particulate soot. The 6.7 Cummins has had a DPF system since halfway through the 2007 model year. 2007.5-2012 models had a completely separate DPF system that sat behind the DOC system. In 2013+ models the DOC and DPF were integrated ... 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 …

Once the DOC is heated up, it can produce high-efficiency oxidization of the post-injected fuel for the DPF regeneration. 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 ...Jan 1, 2022 · The SCR temperature would be even lower than the DOC inlet temperature due to heat transfer to the DOC and DPF catalysts, both upstream of the SCR catalyst. During cold-start and other low exhaust temperature conditions such as idle and low load, higher NO x conversion can be achieved if thermal management strategies are implemented to increase ... On just idling, the truck should be at a 160 degree engine temp and the exhaust should be around 520. As it gets warmer, the exhaust will get warmer. 180 degree truck should have a 600 degree exhaust at idle for this engine and the regen should start activating, the air valve opens, and the truck exhaust gets seriously hotter.The T2 sensor, at the DOC outlet, provides feedbacks for closed loop controls. A fast response control system ensures the DOC outlet temperature stays on target while engine operations vary considerably. To verify the tight DPF inlet temperature control, an active regeneration was enabled during a NRTC test. The results are shown in Figure 8 ...

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).

The vehicle must be parked outside. 11. Perform High Idle Regeneration. 12. When regeneration is complete, clear all fault codes. 13. Road test the vehicle. a. If no fault codes appear, testing is complete. Verify ... jonathan cymrotthe basketball tournament 2023 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.

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 cleaning
