  • Patent number: 8443589
    Abstract: A diesel oxidation catalyst (DOC) testing system includes a DOC that is located in an exhaust system of a vehicle. A control module verifies proper operation of the DOC during a post-fuel injection process in an engine of the vehicle. The control module computes a predicted temperature of exhaust gases at an output of the DOC that corresponds with proper operation of the DOC during the post-fuel injection process, determines an actual temperature of the exhaust gases during the post-fuel injection process, and activates an alarm indicator when a difference between the predicted temperature and the actual temperature is greater than a first predetermined value. A first temperature sensor is located downstream from the DOC in the exhaust system. The first temperature sensor communicates with the control module, generates the actual temperature, and transmits the actual temperature to the control module.
