Necessary conditions for regeneration
When the following conditions are all satisfied,
regeneration will start. However, if even one
condition is deviated from the following conditions
during regeneration process, the regeneration will
be interrupted.
Engine coolant temperature
DPF temperature
Engine speed is 1200 rpm or higher
Usually it takes 15 minutes to 20 minutes to
complete the regeneration cycle.
Actual regeneration time may depend on ambient
temperature, exhaust temperature, and engine
speed.
It is recommended to perform the regenerating
while the engine is warm.
Do not unnecessarily start and interrupt the
regeneration process. Otherwise, a small amount of
fuel becomes mixed with the engine oil, which
degrades the oil quality.
While the DPF is being regenerated, the air-flow
rate of engine is automatically limited to keep up
the exhaust temperature. Because of limit of the air-
flow rate of engine, the engine may sound
differently, but this sound is normal for this engine.
Just after the regeneration has ended, the DPF
muffler remains hot. It is advisable to keep the
engine operating for about 5 minutes to allow
cooling of the exhaust components.
