Abstract
An engine control system that identifies fuel dynamical steady state (FDSS) includes a cylinder and a controller that determines a detection period. The controller monitors a mass of fuel ingested by the cylinder during the detection period. The controller identifies FDSS if the mass of fuel remains within a predetermined range during the detection period.
