AFTERTREATMENT SYSTEM Operating Requirements Engine) or RSL (Stop Engine) are indications of a system problem. Should this occur, refer to the Aftertreatment System Technician's Guide (7SE63), or contact the Detroit Diesel Customer Support Center at 313–592–5800. 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 ATD warranty may be compromised: Illumination of the Diesel Particulate Filter (DPF) lamp indicates that a parked regeneration is required. NOTICE:
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 Detroit Diesel ATD equipped engines will illuminate a dashboard warning lamp indicating the need for ash cleaning. For information on this cleaning procedure, refer to the Aftertreatment System Technician's Guide (7SE63), or contact the Detroit Diesel Customer Support Center at 313–592–5800. Do not use kerosene or fuel blended with used lube oil.
Use Ultra-Low Sulfur Diesel (ULSD) fuel with (15 ppm sulfur content maximum), based on ASTM D2622 test procedure Lube oil must have a sulfated ash level less than 1.0 wt %; currently referred to as CJ-4 oil. NOTICE: Not following the operating requirements may result in damage to the ATD or accelerated ash plugging of the diesel particulate filter.
