摘要： A system includes a cylinder equivalence ratio (EQR) module, a location estimation module, a sensor module, and a fuel control module. The cylinder EQR module determines a first EQR corresponding to a first exhaust gas expelled from a first cylinder and determines a second EQR corresponding to a second exhaust gas expelled from a second cylinder. The location estimation module determines when the first and second exhaust gases mix in an exhaust manifold to form a third exhaust gas having a third EQR. The sensor module estimates an EQR of a fourth exhaust gas based on the third EQR. The fourth exhaust gas is located at an oxygen sensor in the exhaust manifold. The fuel control module controls an amount of fuel supplied to an engine based on a difference between the estimated EQR and an EQR corresponding to measurements from the oxygen sensor.

摘要： An engine control system includes a saturation determination module, an adjustment factor generation module, and a fuel control module. The saturation determination module determines when a first exhaust gas oxygen (EGO) sensor is saturated, wherein the first EGO sensor is located upstream from a catalyst. The adjustment factor generation module generates an adjustment factor for an integral gain of a fuel control module when the first EGO sensor is saturated. The fuel control module adjusts a fuel command for an engine based on differences between expected and measured amounts of oxygen in exhaust gas produced by the engine, a proportional gain, the integral gain, and the integral gain adjustment factor.

摘要： An engine control system includes a proportional correction module and a variable proportional gain determination module. The proportional correction module generates a proportional correction for a fuel command to an engine based on a variable proportional gain and a difference between expected and measured amounts of oxygen in exhaust gas produced by the engine. The variable proportional gain determination module determines the variable proportional gain based on a nominal gain and an amount of time since a polarity of the difference has changed, wherein the nominal gain is based on engine operating parameters.

摘要： A steady-state (SS) delay module determines a SS delay period for SS operating conditions based on an air per cylinder. A dynamic compensation module 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. 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 the fuel and air is expelled from the cylinder. 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 sensor located upstream of a catalyst. A final equivalence ratio module adjusts fuel provided to the cylinder after the third time based on the predicted delay period.
