| titleOfInvention | CATALYST DEGRADATION DETERMINATION METHOD AND CATALYST DEGRADATION DETERMINATION SYSTEM |
| abstract | Catalyst degradation determination method in which the degree of degradation of a catalyst (600) is determined, the catalyst (600) being in an exhaust path (500) of an internal combustion engine (1000) and a target gas contained in an exhaust gas (G) from the internal combustion engine ( 1000), oxidized or adsorbed, wherein the target gas comprises at least one of a hydrocarbon gas and carbon monoxide gas, the method comprising: a) determining whether the oxygen concentration of the exhaust gas (G) determined by a predetermined oxygen concentration determining component (120) is in a range of 15% to 20%, or whether the oxygen concentration of the exhaust gas (G) is 10% or more and varies within a range of ±2% or less of a predetermined value in a predetermined period of time; and b) determining whether the catalyst (600) at a time when it is determined in step a) that the oxygen concentration of the exhaust gas (G) is in the range of 15% to 20% or that the oxygen concentration of the exhaust gas (G) is 10% or more and varies in the range of ± 2% or less of the predetermined value in the predetermined period of time, has been degraded beyond an allowable degree, wherein the step b) is reduced by comparing a determination indicator value determined by an output value from a target gas detection component ( 100) is calculated, and a threshold corresponding to the temperature of the catalyst (600) is performed, wherein the target gas detection component (100) is provided at least at a location downstream of the catalyst (600) in the exhaust path (500) and the target gas can capture. |
