Diesel Particulate Filter Regeneration Important: Minimize the amount of time that you idle the engine or operate the engine at low-engine speed to help reduce the accumulation of soot in the soot filter. The diesel particulate filter (DPF) is part of the exhaust system. The diesel-oxidation catalyst of the DPF reduces harmful gasses and the soot filter removes soot from the engine exhaust.
DPF Ash Accumulation • When enough ash accumulates, the engine • The lighter ash is discharged through the exhaust system; the heavier ash collects in the soot filter. • Ash is a residue of the regeneration process. Over • time, the diesel particulate filter accumulates ash that does not discharge with the engine exhaust. • • The computer for the engine calculates the amount of ash accumulated in the DPF.
Types of Diesel Particulate Filter Regeneration Types of diesel particulate filter regeneration that are performed while the machine is operating: Type of Regeneration Conditions for DPF regeneration DPF description of operation Passive Occurs during normal operation of the machine at high-engine speed or high-engine load The InfoCenter does not display an icon indicating passive regeneration.
Types of diesel particulate filter regeneration that require you to park the machine: (cont'd.)
