Abstract: Systems and methods are described for operating a turbocharger. A current exhaust manifold pressure is determined based on an engine operating condition. A current operating condition of the turbocharger is determined. A surge correction factor is determined based on the current operating condition of the turbocharger. The current exhaust manifold pressure is adjusted based on the surge correction factor.

Abstract: A turbocharger control method and related systems are provided. An operational command to control a level of boost provided by the turbocharger is received. In response to receiving the operational command, an exhaust gas recirculation (EGR) valve is instructed to move from a current position to a desired position. A time taken for the EGR valve to move from the current position to the desired position is determined. A maximum rise rate of exhaust manifold pressure corresponding to a predicted EGR valve position is determined. A permitted exhaust manifold pressure limit for the turbocharger is determined based on a current exhaust manifold pressure, the maximum rise rate of exhaust manifold pressure and the time taken. An operation of the turbocharger is controlled such that the permitted exhaust manifold pressure limit is not exceeded.

Abstract: Methods and systems are provided for coordinating operation of a high pressure EGR control loop with a boost pressure control loop. In one example, following a tip-in, turbine vane position may be adjusted as a function of a maximum permissible exhaust pressure upstream of a turbocharger turbine. The maximum permissible exhaust pressure may be determined as a function of a HP EGR valve position at the time of the tip-in.

Abstract: Methods and systems are provided for adjusting an EGR valve operation based on results from an EGR valve diagnostic. In one example, a method may include executing the EGR valve diagnostic during an engine deactivation, wherein the EGR valve diagnostic estimates an EGR valve stickiness used to adjust the EGR valve operation.

Abstract: Methods and systems are provided for an EGR valve diagnostic. In one example, a method may include actuating an EGR valve between first and second positions. The method may further includes determining one or more characteristics of the EGR valve during the diagnostic to determine if an EGR valve cleaning is desired.

Abstract: A method of operating an engine assembly is provided. The engine assembly comprises an engine and a turbocharger assembly, wherein a control parameter of the turbocharger assembly is controllable in order to control a level of boost provided by the turbocharger assembly. The method comprises determining a desirable pressure limit of exhaust gases upstream of a turbine of the turbocharger assembly, predicting a desirable limit value of the control parameter to be applied to the turbocharger assembly in order to achieve the desirable pressure limit, determining an error in the desirable limit value of the control parameter, adjusting the desirable limit value of the control parameter based on the error, and controlling the operation of the turbocharger assembly such that the adjusted limit value is not exceeded.
