Inventor: UCHIKAWA AKIRA
IPC: F02D41/14
Filed: 1988-12-23
Abstract: PURPOSE:To suppress the concentrations of CO/HC in a long term by correcting feedback control of an air-fuel ratio while detecting the deteriorated condition of an O2 sensor. CONSTITUTION:Deterioration of an O2 sensor particularly accelerates the change from a rich side to a lean side, and increase the response speed totally. When the operation condition for stabilizing increase/decrease frequency of a fuel supply amount is detected by an operation detection means during practicing feedback control of an air-fuel ratio, the deteriorated condition of the O2 sensor is detected by a deterioration judgement means according to the increase/ decrease frequency of fuel supply amount. When the deterioration of the O2 sensor is judged, the starting time of increase amount control of the fuel supply amount is delayed by a specified time from the detection of inversion of the air-fuel ratio to a lean side from a target value through an output value of the O2 sensor by means of an increase amount control delay means. As a result, ratios of rich and lean periods are equal to each other to suppress the CO and HC in a long term.
