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 are provided for controlling a vehicle engine to adjust exhaust warm-up strategy based on a vehicle network information. In one example, in response to an expected decrease in temperature of a catalyst of a vehicle below a threshold and an estimated duration thereof based on communications external from the vehicle, a method may include delaying catalyst heating actions, when the catalyst heating actions are determined to be unable to heat up the catalyst to threshold temperatures. However, the catalyst heating actions may be enabled when the catalyst heating actions are determined to be able to achieve the threshold temperature within the duration.

Abstract: A method for operating a vehicle system is described herein. The method includes indicating a variable geometry turbine degradation based on a comparison of a modeled set of turbine pressure values and a sensed set of turbine pressure values, each set of turbine pressure values including a pressure value upstream of the turbine and a pressure value downstream of the turbine and the variable geometry turbine positioned downstream of an engine cylinder.

Abstract: Methods and systems are provided for providing passive boost pressure monitoring for slow response with higher confidence. A response time of a boost pressure feedback control loop following a boost pressure deviation that is triggered by either system disturbances or operator torque demand is monitored. Slow boost behavior is correlated with boost control degradation affecting drivability and emissions.

Abstract: Methods and systems are described for an engine with a SCR system including NOx sensors upstream and downstream of catalyst. One method includes monitoring SCR performance via calculating SCR conversion efficiency at different catalyst temperatures. Further, feedgas NOx levels are artificially increased when SCR device temperature is above a threshold to obtain more reliable readings from NOx sensors.
