摘要： A control apparatus and method for an internal combustion engine are provided for ensuring a stable combustion state and improving the fuel efficiency when an air-fuel mixture is burnt with self ignition while auxiliarily using a spark ignition. The control apparatus for an internal combustion engine which is operated in a plurality of modes including a torch self ignition combustion mode comprises an ECU. In the torch self ignition combustion mode, the ECU controls an internal EGR amount, calculates an actual exhaust closing angle, calculates a target exhaust closing angle, calculates a closing angle deviation, calculates a fuel injection amount for forming a homogeneous air-fuel mixture, calculates a correction coefficient in accordance with the closing angle deviation, and corrects a basic value by the correction coefficient to calculate a fuel injection amount for forming a stratified air-fuel mixture.

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： The air-fuel ratio of an air-fuel mixture to be combusted in an internal combustion engine 1 is manipulated to converge an output VO2/out of an O2 sensor 6 which is disposed downstream of a catalytic converter 3 to a target value VO2/TARGET depending on an operating state of the internal combustion engine 1, while at the same time a deterioration evaluating parameter is determined from time-series data of the output VO2/out of the O2 sensor 6. The value of the deterioration evaluating parameter is corrected depending on an average value of the output VO2/out of the O2 sensor 6 or the target value VO2/TARGET, and the deteriorated state of the catalytic converter 3 is evaluated based on the corrected value of the deterioration evaluating parameter.

摘要： A control system for an internal combustion engine is disclosed. The engine is provided with at least one fuel injection valve for injecting fuel supplied from a fuel tank into an intake pipe of the engine. The fuel injection amount is controlled by controlling the valve opening period of the at least one fuel injection valve. A pressure difference between the pressure of fuel to be supplied to the at least one fuel injection valve and the pressure in the fuel tank is controlled such that the difference is at a constant value. The pressure in the fuel tank and the pressure in the intake pipe are detected. A correction amount is calculated according to the pressure in the fuel tank and the pressure in the intake pipe, and the valve opening period of the at least one fuel injection valve is corrected using the calculated correction amount. A required amount of fuel to be supplied to the engine is calculated according to an operating condition of the engine. The change rate of the correction amount is corrected according to the required fuel amount.

摘要： An air-fuel ratio control system for an internal combustion engine has a sensor which detects the air-fuel ratio of exhaust gases in an exhaust passage of the engine emitted from a plurality of cylinders. An air-fuel ratio of a mixture supplied to each of a plurality of cylinders is estimated, based on the detected air-fuel ratio and a model representative of a behavior of the exhaust passage. A cylinder-by-cylinder air-fuel ratio control amount is calculated for use in controlling the air-fuel ratio of the mixture supplied to the each of the cylinders in a feedback manner responsive to the estimated air-fuel ratio of the mixture such that the estimated air-fuel ratio of the mixture supplied to the each of the cylinders is converged to a desired air-fuel ratio. A learned value of the cylinder-by-cylinder air-fuel ratio control amount is calculated. When the difference between the detected air-fuel ratio and the estimated air-fuel ratio of the mixture supplied to the each of the cylinder is larger than a predetermined value, the calculation of the learned value of the cylinder-by-cylinder air-fuel ratio control amount is inhibited.
