| titleOfInvention | Internal combustion engine catalyst deterioration judgment system |
| abstract | The present invention relates to a method for accurately determining the degree of deterioration of an exhaust purification catalyst and suppressing deterioration of drivability due to an influence on an operating state of an internal combustion engine when the degree of deterioration is determined. When the three-way catalyst is in a rich atmosphere and the fuel cut F / C is executed, the occlusion reaction heat THca is changed after the inflow exhaust air-fuel ratio AFin shifts from the rich air-fuel ratio AFrich to the lean air-fuel ratio AFlean. The reaction heat detection period Δt until it is detected is measured (S104 to S106). Then, the maximum oxygen storage amount Comax is calculated based on the reaction heat detection period Δt, and the degree of deterioration of the three-way catalyst 4 is determined (S107, S108).
