LifeGaurd SRS System:
DPF (Diesel Particulate Filter) Aftertreatment System:
The Diesel Particulate Filter
(DPF)
system is set up to reduce the amount of pollution
emitted into the air. This is done by maintaining the soot in the catalytic converter and
stores it until the build up reaches a certain amount, which will be burned off during the
regeneration process. The Detroit Diesel Electronic Control
(DDEC)
will determine
when the regeneration process is necessary. It would be highly unlikely that the system
would perform an automatic regeneration due to the fact that we would probably not
keep up a high rate of speed for approximately 30 – 40 minutes on any normal run.
There is no telling when or how often this may occur, it depends solely on the type of
driving the apparatus performs. So that would mean we would probably perform
manual regenerations, when it is called for
Figure 25
. While an apparatus is
performing a regeneration there should be safety precautions taken, such as assign a
firefighter to maintain an area of at least 5-10 feet in all direction of the exhaust pipe
due to extreme exhaust temperatures
Figure 26
. If during a manual regeneration
your apparatus is called for another run, you will stop the regeneration process by
releasing the Maxi-brake and placing the apparatus in the drive position. Place the
transmission selector in drive this will automatically stop the regeneration process. This
would be considered a partial regeneration and it would require you to start a new
manual regeneration when you return to quarters and continue the process until
regeneration is completed.
Note:
The
DPF
system will not activate while the apparatus is in either the
HIGH
IDLE
mode or in
PTO
mode.
The apparatus is equipped with the LifeGaurd SRS
system. This provides side roll protection for the driver,
officer and rear-facing seat behind the driver.
Figure 24.
The system will be activated in any type of rollover
crash.
