Abstract:
A system according to the present disclosure includes a fuel control module and at least one of a desired air per cylinder (APC) module and a predicted manifold absolute pressure (MAP) module. The desired APC module determines a desired amount of airflow to each cylinder of an engine. The predicted MAP module predicts a pressure within an intake manifold of the engine at a future time. The fuel control module selectively adjusts a fuel injection parameter of the engine based on at least one of: a change in the desired air per cylinder from a first time to a second time; and a change in the predicted manifold pressure from the first time to the second time.
