摘要： The internal combustion engine controller includes an oxygen concentration sensor outputting an electric signal having a value depending on an oxygen concentration in an exhaust gas flowing through an exhaust passage of an internal combustion engine, and a control unit controlling fuel injection amount depending on at least the electric signal, the control unit being capable of performing atmospheric learning to calibrate the oxygen concentration sensor. The control unit is configured to perform the atmospheric learning when a changing rate of the value of the electric signal is lowered from above a predetermined threshold rate to below the predetermined threshold rate after a time of start of cutoff of fuel supply to the engine.

摘要： An EGR control system that is capable of controlling the amount of recirculation of high-temperature and low-temperature recirculated gases, with high accuracy, to thereby improve the control accuracy of in-cylinder temperature. An ECU of an ERG control system calculates a fresh intake air ratio, and sets a target value of the fresh intake air ratio. The ECU calculates a feedback correction coefficient for converging the fresh intake air ratio to the target value, with an I-PD control algorithm, and sets an external EGR ratio and an internal EGR ratio. The ECU controls the EGR amount whose ratio is the larger, according to the larger one of the two ratios and the feedback correction coefficient, and controls the EGR amount whose ratio is the smaller, according to the smaller of the ratios and the learned value thereof.

摘要： A method of controlling ignition timing of an engine. In the control method, final ignition timing for performing ignition is calculated by adding a variation component to a set ignition timing. According to the final ignition timing, an indicated average effective pressure of an in-cylinder pressure detected when ignition is performed is calculated. An ignition timing characteristic curve indicating the correlation between the indicated average effective pressure and the variation component is estimated and optimal ignition timing is calculated from the characteristic curve. Feedback control for converging the set ignition timing to the optimal ignition timing is then performed. Consequently, the ignition timing is controlled to an optimal ignition timing corresponding to a current operational state of the engine.
