| abstract | (57) [Summary] [PROBLEMS] To enable early activation of a catalyst, reduce emission of harmful substances in a low temperature range, and suppress grain growth of a noble metal when oxygen is supplied. An engine is stopped and oxygen is supplied from an air pump to the catalyst in a state where the temperature of the catalyst is equal to or lower than a predetermined temperature to make the oxygen storage amount of the catalyst substantially saturated. By pre-storing oxygen in the catalyst and setting it in a substantially saturated state, the purification activity in a low-temperature region at the time of starting or the like is improved. By supplying oxygen in a state where the temperature of the catalyst is equal to or lower than the predetermined temperature, grain growth of the noble metal is suppressed. |
