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 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.
