Diagnosis control method for internal combustion engine |
| abstract |
An opportunity for determining an abnormality of a catalyst or an air-fuel ratio sensor downstream of the catalyst is secured. The output from the air-fuel ratio sensor 12 provided downstream of the catalyst 3 is referred to until the air-fuel ratio of the gas flowing into the catalyst 3 is forcibly manipulated until the air-fuel ratio downstream of the catalyst fluctuates. In the diagnosis method of estimating the amount of oxygen occluded in the catalyst 3 by measuring the elapsed time, if a fuel shift occurs due to a shift change of the transmission during the diagnosis, the fuel is being cut Gradually increased the oxygen storage amount, and after the fuel cut was completed, the diagnosis was continued starting from the oxygen storage amount at the end of the fuel cut. As a result, even if a shift change is made during diagnosis, it can be completed without stopping the diagnosis. [Selection] Figure 4 |
