Abstract: Various systems and methods are described for detecting ammonia slip. In one example method, an exhaust system with two NOx sensors uses transient responses of the NOx sensors to allocate tailpipe NOx sensor output to NOx and NH3 levels therein. An ammonia slip detection counter with gains is included that determines a probability of NOx and NH3 based on the measured sensor activities that are further processed by a controller to adjust one or more parameters based on the allocation and changes of sensor output.

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: A method for diagnosing a performance issue in a vehicle system having a diesel engine, a fuel system, and an on-board diagnostic system. The method includes cranking the engine, and, if a pressure sensed in the fuel system during or after the engine cranking differs by a threshold amount from the pressure sensed during a previous operation of the engine, indicating excessive fuel viscosity in the on-board diagnostic system.
