Diesel Particulate Filter Regeneration - Toro Reelmaster 7000-D Operator's Manual

Diesel Particulate Filter Regeneration

DPF Soot Accumulation
• Over time, the diesel particulate filter accumulates soot in the soot filter. The computer for
the engine monitors the soot level in the DPF.
• When enough soot accumulates, the computer informs you that it is time to regenerate
the DPF.
• DPF regeneration is a process that heats the DPF to convert the soot to ash.
• In addition to the warning messages, the computer reduces the power produced by the
engine at different soot-accumulation levels.

DPF Ash Accumulation
• 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.
• When enough ash accumulates, the engine computer sends information to the
InfoCenter in the form of an engine fault to indicate the accumulation of ash in the DPF.
• The fault messages indicate that it is time to service the DPF.
• In addition to the warnings, the computer reduces the power produced by the engine at
different ash-accumulation levels.
