摘要： A method of controlling the air-fuel ratio of a mixture being supplied to an internal combustion engine, in a feedback manner responsive to output from an O.sub.2 sensor arranged in the engine exhaust system for sensing the concentration of a component in exhaust gases from the engine to produce as the output a normally fluctuating output signal indicative of the concentration. The air-fuel ratio is controlled to a desired value by means of at least one of proportional control applying a first correction value to correct the air-fuel ratio when the output signal changes from a rich side to a lean side or vice versa with respect to a predetermined reference value, and integral control applying a second correction value to correct the air-fuel ratio whenever a predetermined period of time elapses so long as the output signal remains on the lean side or on the rich side with respect to the predetermined reference value. At least one of the first and second correction values is set to a smaller first value as load on the engine is higher, and the set at least one correction value is applied to correction of the air-fuel ratio in a direction of enriching the mixture.

摘要： A method of controlling an operation of an internal combustion engine. A memory has stored therein a plurality of basic values of a control amount by which the operation of the engine is to be controlled, and which conform to at least one operating parameter of the engine, as well as at least one correction value for correcting the basic values. When each of first and second conditions is detected under which the operation of the engine is required to be controlled by respective different amounts, ones of the basic values are read from the memory, which corresponds to the value of the at least one operating parameter. When a predetermined one of the first and second conditions is detected, the at least one correction value is read from the memory, by which the read basic values are corrected by the read correction value. The operation of the engine is controlled by control amounts based upon the corrected basic values. The operation of the engine includes control of fuel supply to the engine and exhaust gas recirculation control.

摘要： An air-fuel ratio control system for an internal combustion engine has an exhaust gas component concentration sensor having a sensor element and arranged in the exhaust system of the engine, for detecting concentration of a predetermined component present in exhaust gases emitted from the engine. An ECU controls the air-fuel ratio of an air-fuel mixture supplied to the engine, based on results of comparison between an output value from the sensor and a predetermined reference value, and detects deterioration of the exhaust gas component concentration sensor, based on the output value from the sensor. Engine operating condition sensors detect operating conditions of the engine. It is determined whether or not the engine is in a predetermined engine operating condition in which the sensor element temperature of the exhaust gas component concentration sensor lowers, based on outputs from the engine operating condition sensors. Detection of deterioration of the sensor is inhibited over a predetermined time period after the engine leaves the predetermined operating condition.

摘要： A failure-detecting device detects failure of an air-fuel ratio sensor arranged downstream of a three-way catalyst in an exhaust passage of an internal combustion engine. The air-fuel ratio of an air-fuel mixture supplied to the engine is perturbed with a predetermined repetition period and by a predetermined amplitude. There is detected an amount of change in an output from the air-fuel ratio sensor responsive to the perturbed air-fuel ratio. Failure of the air-fuel ratio sensor is detected based on the amount of change in the output from the air-fuel ratio sensor.

摘要： An ignition timing control system of the vehicle internal combustion engines which conducts ignition timing control retard adjustment during vehicle acceleration so as to eliminate vibration of the vehicle body caused by the sudden change in the engine output. When the vehicle acceleration is detected, the ignition timing is immediately retarded for a period and after the expiration of the period, the retard adjustment is continued so long as the engine speed increases and discontinued when the engine speed turns to decreases. As a result of the repeated ignition timing control, the overall ignition timing characteristics take on a zigzag pattern. The ignition timing is thus controlled to reduce the output torque when the torque tends to rise because the engine speed is rising, while the retard correction is discontinued so as to prevent a decrease in output torque when the engine output torque tends to decline. As such, by deliberately imparting a phase difference to the output, the change in the engine speed is averaged to result smooth rising during acceleration without causing the vibration to the vehicle body.
摘要翻译： 车辆内燃机的点火正时控制系统，其进行点火正时控制，在车辆加速期间进行延迟调整，以消除由于发动机输出突然变化引起的车身振动。 当检测到车辆加速度时，点火正时立即延迟一段时间，并且在该期间结束之后，只要发动机转速变低，发动机转速增加并停止，继续调节。 作为反复点火正时控制的结果，总点火正时特性呈锯齿状。 因此，由于发动机转速上升，当转矩趋于上升时停止点火正时，同时延迟校正停止，以防止发动机输出转矩下降时输出转矩的降低。 因此，通过故意地向输出赋予相位差，发动机转速的变化被平均，从而在加速期间平滑地上升而不会对车身产生振动。

摘要： A system for controlling ignition timing of an internal combustion engine which is capable of securing adequate ignition energy in all engine operation regions including acceleration or high speed engine operation. The retard limit for ignition timing is determined with respect to engine speed. A ratio of dwell angle on an ignition coil to a prescribed angle is calculated and compared with reference value. When the ratio is found to exceed the reference value, the retard limit is changed in advance direction so that ignition timing is caused to be advanced. Misfirings are thus avoided.

摘要： An air-fuel ratio feedback control method for an internal combustion engine in which when the engine is operating in a feedback control region, the concentration of an ingredient in exhaust gases from the engine is detected by an exhaust gas ingredient concentration sensor arranged in the exhaust system of the engine and compared with a reference value, and the air-fuel ratio of an air-fuel mixture to be supplied to the engine is controlled to a desired value in a feedback manner responsive to the result of the comparison. Atmospheric pressure is detected, and the reference value is set to a value depending on the detected value of atmospheric pressure. The reference value is set to a higher value as the detected value of atmospheric pressure is lower. The reference value is set to a lower value when the engine is operating in an idling region than when the engine is operating in a region other than the idling region.
