    摘要： 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.

    摘要： An oxygen storage capacity (OSC) monitoring system for a vehicle having a catalytic converter includes a control module that determines a measured OSC based on an inlet sensor signal (ISS) that is responsive to an oxygen content of exhaust flowing into the catalytic converter. The control module determines a normalization ratio based the measured OSC and determines a PASS/FAIL status of the catalytic converter based on the normalization ratio.

    摘要： An intake air temperature (IAT) sensor diagnostic module comprises a measured noise module, an expected noise module, an excess noise module, and an IAT fault detection module. The measured noise module measures noise in an IAT signal from an IAT sensor in a vehicle. The expected noise module determines expected noise based upon the IAT signal. The excess noise module determines an excess noise value based upon the measured noise and the expected noise. The IAT fault detection module diagnoses faults in the IAT sensor based upon a comparison of the excess noise value and a first predetermined value.

    摘要： A diagnostic cold start emissions control system for an internal combustion engine includes a control module having a calculated engine-out energy module, an engine-out energy residual module, and a diagnostic system evaluation module. The calculated engine-out energy module is in communication with the engine-out energy residual module and is configured to determine an operating engine-out energy flow based on an operating engine torque. The engine-out energy residual module is in communication with the diagnostic system evaluation module and is configured to determine an engine-out energy residual based on the determined engine-out energy flow and an expected engine-out energy flow. The diagnostic system evaluation module is configured to determine whether the determined engine-out energy residual meets a predetermined value indicative of proper cold start emissions control.
