ABSTRACT:
A method of controlling an internal combustion engine when the engine is operating in an engine braking mode is provided. The engine operates in the engine braking mode and an exhaust valve for the cylinder is prematurely opened to dissipate power. The method includes controlling airflow to at least one cylinder based on a comparison of a desired mass airflow rate and an actual mass airflow rate such that the actual mass airflow rate tracks the desired mass airflow rate.
