Can I reassign or relocate a piece of equipment with a passive DPF installed without doing another temperature trace?
No. If a piece of equipment is successfully using a passive regenerating DPF in one operational scenario, and is moved to a different location where the pitch of the ramps may be different, or the tasks being performed are different, exhaust temperature traces should be obtained for the new deployment. If the exhaust temperatures are not sufficient to support passive regeneration, the DPF will continue to load with soot. Excessive loading creates excessive exhaust back pressure (the back pressure alarm should come on) and the DPF system must be removed from the equipment and regenerated manually. An attempt to use the engine at excessive back pressures may result in damage to the engine, increased soot and CO emissions, increased exhaust temperatures, and possibly the uncontrolled regeneration of the DPF, resulting in the possible destruction of the DPF.
