摘要： A method for reusing a vehicular catalyst that ensures effective reuse of a catalyst discarded when a vehicle is discarded is provided. A catalyst deterioration level of a catalytic converter is diagnosed, a catalyst that has a value of the deterioration level diagnosed to be smaller than a predetermined value is determined as a reusable catalyst, and the catalytic converter that includes the catalyst determined as the reusable catalyst is removed from a discarded vehicle. The removed catalytic converter is stored in association with a vehicle type and a manufacturing time of the discarded vehicle. When an abnormality occurs in a catalyst of a drivable vehicle corresponding to the vehicle type and the manufacturing time, a catalytic converter that includes the abnormal catalyst is replaced with the stored catalytic converter.

摘要： A reuse evaluation system is a system that performs an evaluation to reuse a catalyst in a state where the catalyst that purifies an exhaust gas of an engine of a vehicle 1 is mounted on the vehicle. The reuse evaluation system includes a deterioration estimator that estimates a degree of deterioration of the catalyst based on an operating state of the vehicle, a reuse setting unit that sets a range of the degree of deterioration of the catalyst as a reuse range of the catalyst according to a usage of reuse of the catalyst, and a reuse determining unit that determines that the catalyst is reusable in the reuse usages when the degree of deterioration of the catalyst estimated by the deterioration estimator is within the reuse range set by the reuse setting unit.
