Abstract: A method for operating a turbocharged engine is disclosed. In one example, during a first condition an engine operation is adjusted in response to a turbocharger expansion ratio exceeding a first limit and during a second condition an engine operation is adjusted in response to the turbocharger expansion ratio exceeding a second limit that differs from the first limit. Degradation of the engine may be reduced under some engine operating conditions by adjusting engine operation in response to the turbocharger expansion ratio.

Abstract: Methods and systems for operating an engine that includes a controller and a NOx sensor are described. In one example, output of the NOx sensor is selectively made available to software modules within the controller when an offset in NOx sensor output is not expected. If the offset in NOx sensor output is expected, the NOx sensor output may not be made available to the software modules.

Abstract: Systems and methods for detecting ammonia slip in an exhaust system based upon transient NOx sensor responses are described. In one example method, an exhaust system allocates tailpipe NOx sensor output to NOx and NH3 levels responsive to the transient sensors using a segment length method that processes the transient signals based on the total segment lengths calculated within a window. A ratio of segment lengths relative to a threshold is determined for a measured and expected NOx rate of change downstream of an SCR that is further used to determine a probability of NOx and NH3 based on the measured sensor activities, and a controller is included to adjust one or more parameters based on the allocation and changes of sensor output.
