Abstract: Methods and systems are provided for coordinated operation of electric variable geometry turbocharger (e-VGT), an exhaust gas recirculation (EGR), and electric motor coupled to the e-VGT for expedited catalyst light-off. In one example, a method may include, during a cold-start, decreasing each of an opening of e-VGT vanes and an opening of an EGR valve while operating the electric motor for braking and reducing the e-VGT speed.

Abstract: Methods and systems are provided for electrically-assisted engine braking. In one example, a method may include operating a turbocharger by an electric motor during engine braking to increase air flow to an engine intake. The enhanced air flow into the engine intake increases an exhaust manifold pressure, thus increased a braking force provided by engine braking.

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: Methods and systems are provided for modeling a reductant temperature and storage distribution of a SCR catalyst axially and radially. In one example, a method may include modeling an expected distribution of stored reductant among a plurality of axial zones and a plurality of radial zones of an SCR catalyst arranged in an engine exhaust passage and comparing the expected distribution with a reductant storage setpoint of each zone to adjust radial and axial storage locations.

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: Various systems and method for detecting exhaust NOx sensor degradation are disclosed. In one example, degradation of the NOx sensor is indicated responsive to reductant injection in an exhaust passage under engine off conditions. For example, degradation of the NOx sensor is indicated when an actual NOx sensor output differs from an expected NOx sensor output by more than a threshold amount.

Abstract: Various systems and methods are described for managing ammonia storage in an SCR catalyst. In one example approach, a method comprises, in response to a vehicle-off event, injecting ammonia during a final exhaust blowdown until a predetermined value of ammonia is stored in the SCR catalyst; and in response to a subsequent vehicle-on event when an amount of ammonia stored in the SCR catalyst is less than the predetermined value, injecting ammonia until the predetermined value of ammonia is stored in the SCR catalyst.
