Soot
filter
traps
all
soot
particles
and
hydrocarbon.

It
needs
to
burn
off
the
trapped
soot
particles.

A
key
measure
of
its
performance
is
the
balance
point
temperature.

The
balance
point
temperature
varies
from
engine
to
engine.

Balance
point
temperature:
the
engine
operating
condition
and
the
exhaust
temperature
where
soot
burn
off
rate
is
greater
than
or
equal
to
the
engine
soot
output.
