Patent ID: 8113187

Claim:
A system for a vehicle, comprising: a steady-state (SS) delay module that determines a SS delay period for SS operating conditions based on an air per cylinder (APC); a dynamic compensation module that determines a predicted delay period based on first and second dynamic compensation variables for dynamic operating conditions, the SS delay period, a previous predicted delay period, wherein the first dynamic compensation variable corresponds to a period between a first time when fuel is provided for a cylinder of an engine and a second time when exhaust gas resulting from combustion of a mixture of the fuel and air is expelled from the cylinder, and wherein the SS and predicted delay periods correspond to a period between the first time and a third time when the exhaust gas reaches an exhaust gas oxygen (EGO) sensor that is located upstream of a catalyst; and a final equivalence ratio (EQR) module that adjusts an amount of fuel provided to the cylinder after the third time based on the predicted delay period.
