摘要： An internal combustion engine includes a particulate filter that is configured to treat exhaust gas. A method for monitoring the particulate filter includes employing a soot sensor to monitor the exhaust gas downstream of the particulate filter. A fault is detected in the particulate filter when accumulated soot mass indicated by the soot sensor exceeds a soot mass threshold over a course of engine operation between a first regeneration event and a second regeneration event of the particulate filter. A control module associated with operation of the internal combustion engine is notified of the fault.

摘要： An exhaust gas aftertreatment system for a diesel engine is provided. The system includes a controller operably coupled to the engine that induces the engine to combust a rich air/fuel mixture in at least one cylinder at a predetermined time interval after startup of the engine to output exhaust gases including elevated levels of CO, and a percentage increase in HC that is less than a minimal threshold percentage relative to combusting a lean air/fuel mixture. The system further includes a diesel oxidation catalyst that receives the exhaust gases and oxidizes the CO to obtain an exothermic reaction that increases a temperature of the exhaust gases flowing through the oxidation catalyst to greater than a threshold temperature level. The system further includes an SCR catalyst which receives the exhaust gases and reduces NOx in the exhaust gases.
