Beschreibung
Zusammenfassung:	A system and method for monitoring the temperature in a vehicle after-treatment system is provided. The system includes one or more temperature sensors positioned in the vehicle after-treatment system and an electronic control unit (ECU) configured by programming instructions encoded in computer readable media to execute a method. The method includes monitoring the temperature presented by the one or more temperature sensors, executing a lower oxygen combustion strategy for a slower exothermic reaction when the temperature exceeds a first threshold level, and deactivating the lower oxygen combustion strategy when the temperature drops below a second threshold level.
