Oxidation of the particulate matter is the key to filter performance. This requires that the
catalyzing agent (platinum coated passages) are providing optimum enhancement to the
oxidation process. The following requirements must be met; otherwise the warranty may be
comprimised:
NOTE: Do not use kerosene or fuel blended with used lube oil.
1.
Use Ultra - Low Sulfur Fuel (ULSF) with 15 PPM sulfur content or less, based
on ASTM D2622 test procedure.
2.
Lube oil must have a sulfated ash level less than 1.0wt%; currently referred to
as CJ-4 oil.
NOTE: Not following the operating requirements may result in damage to the
ATD or accelerated ash plugging of the diesel particulate filter.
Maintenance
A high amount of black smoke emitting from the vehicle or illumination of the Amber
(Yellow Engine Warning) Warning Light or Red Stop Light are indications of a system problem.
Illumination of the yellow light indicates that a parked regeneration is required. There is a
need to periodically remove accumulated ash, derived from engine lube oil, from the filter.
This ash does not oxidize in the filter during the regeneration process and must be
removed through a cleaning procedure. All Terex Truck Cranes equipped with diesel Tier lll
engines will illuminate a dashboard warning: light indicating the need for ash cleaning.
Parked Regeneration
Regeneration of the ATD is fundamental for the oxidation of soot. This process happens
during the normal operation cycle of the truck crane; it can occur both passively or actively.
Regardless of this, the operator will see no difference in performance or control. If the ATD
is not capable of completing regeneration due to duty cycle constraints or other
restrictions, a parked regeneration may need to occur.
