Abstract
The state of internal combustion engine inlet air dynamics is characterized in a substantially noise immune albeit rapid manner according to the degree by which a first set of criteria indicate a steady state condition in which engine inlet air rate substantially corresponds to cylinder inlet air rate or to the degree by which a second set of criteria indicate a transient condition in which engine inlet air rate does not substantially correspond to cylinder air rate. Cylinder inlet air rate may then be predicted in accord with the characterization.
