Method and system for transient airflow compensation in an internal combustion engine
First Claim
1. A method for determining airflow to a cylinder of an internal combustion engine, such airflow passing to the cylinder through an intake manifold, comprising:
- 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 airflow from the intake manifold towards the desired cylinder airflow; and
providing such compensation airflow to the intake manifold.
