Abstract
An inlet air dynamics (IAD) characterization control system for an internal combustion engine includes a first module that estimates a future firing event manifold absolute pressure (MAP) and a second module that determines a MAP cycle difference based on the future firing event MAP and a previous cycle MAP. A third module characterizes an IAD state based on the MAP cycle difference.
