Document Type and Number:
Japanese Patent JP3331650
Kind Code:
B2
Abstract:
An air-fuel ratio control system for an internal combustion engine in which an exhaust sensor is located in an exhaust path of the internal combustion engine. A control means provides feedback control to match an air-fuel ratio with a target value in accordance with a detection signal from the exhaust sensor. The control means is provided with a correction section which, upon fulfillment of predetermined implementation conditions of correction determination, detects a response time that elapses from the occurrence of a change in an operating state of the internal combustion engine until the detection signal from the exhaust sensor issues a determination signal value. The correction section governing the feedback control of the air-fuel ratio corrects the feedback control in accordance with the detected response time.
