Abstract: An engine control module (ECM) may obtain information concerning a speed of an engine, information concerning an exhaust gas temperature, information concerning an engine airflow rate, information concerning a pressure of an intake manifold associated with the engine, and information concerning a requested amount of engine braking power. The ECM may cause one or more components of a variable geometry turbocharger (VGT) to adjust based on the information concerning the speed of the engine, the information concerning the exhaust gas temperature, and the information concerning the engine airflow rate. Additionally, or alternatively, the ECM may cause the one or more components of the VGT to adjust based on the information concerning the pressure of the intake manifold associated with the engine and the information concerning the requested amount of engine braking power.
