Abstract
A method for determining airflow to a cylinder of an internal combustion engine, such airflow passing to the cylinder through an intake manifold. The method includes providing a model of the intake manifold, such model providing a relationship between expected output airflow from the intake manifold in response to airflow into the intake manifold; determining from the model the expected output airflow from the intake manifold from a previous commanded airflow into the intake manifold; determining a compensation airflow required for the input airflow to the intake manifold to drive the expected output from the intake manifold towards the desired cylinder airflow; and providing such compensation airflow to the intake manifold.
