Abstract
A method and system for adaptive transient fuel compensation in an engine (300) estimates fuel puddle dynamics for a cylinder in an engine by determining parameters of a wall-wetting model on every engine cycle by measuring a temporal delay (407) between when an identification fuel charge is injected (405) and when a binary-type exhaust gas oxygen sensor (213) switches state. Fuel delivery to the cylinder is adjusted (417) dependent on the estimated fuel puddle dynamics which are a function of the measured temporal delay (407).
