| titleOfInvention | Catalyst deterioration detection device for internal combustion engine |
| abstract | (57) 【Abstract】 PROBLEM TO BE SOLVED: To prevent the catalyst deterioration due to the catalyst deterioration determination parameter based on the oxygen concentration sensor output, which is caused by the air-fuel ratio of the air-fuel mixture being biased to the rich side due to the influence of the evaporated fuel purged into the intake system. Provided is a catalyst deterioration detection device capable of preventing erroneous detection and making accurate deterioration determination. SOLUTION: When the value of the evaporation correction coefficient KEVAP, which is set to a smaller value as the influence of the evaporated fuel to be purged increases, is 1.0 (non-correction value), deterioration determination is executed and KEVAP <1. When it is 0, the deterioration determination is prohibited (S11). Also, when the learning value KEVAPREF of the evaporation correction coefficient KEVAP is larger than the predetermined value KEVAPCAT, the deterioration determination is prohibited (FIG. 3, S33). |
