What should the Doc inlet be for a Regen?
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.
What should exhaust temps be when running Regen?
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. This is actually done by the turbo vanes closing, causing high exhaust back pressure and load on the engine.
What happens if the Regen cycle is not completed?
If the DPF regen cycle is not taking place, or not completing a full cycle, a ‘check engine’ light might illuminate on your dash. In doing so the many sensors in the system will calculate the particulates prior to the DPF and post, recognizing a lack in operation of the DPF.
What should the Doc Inlet and DPF inlet be?
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.
What should the Regen temps be on a Cummins Engine?
Intake manifold pressure – 10-14″ Hg – Low could indicate boost or air to air leaks. Percent load – less than 2% (with the fan off) I’ve seen most regens fail with this at 5% or higher. This is also what is near 0% with a cold engine and 5-7% with a hot engine. Typically a weak metering actuator, the engine heat makes the actuator weak.
What should intake gas pressure be during Regen?
Monitor these parameters during a regen, and you should have these values; EGR valve position – 0% – EGR valve must be closed. Exhaust gas pressure – 120-150″ Hg – Low could indicate a failing turbo. Intake manifold pressure – 10-14″ Hg – Low could indicate boost or air to air leaks.
