| 摘要 |
The arrangement according to the invention permits the optimal control of the air/fuel ratio of an air/fuel mixture supplied to an internal combustion engine while considering the gas storage capability of a catalyzer. The degree of conversion of the catalyzer is dependent upon the oxygen content of the exhaust gas which is available. Since this degree of conversion is partially influenced by the oxygen given off by the catalyzer, a targeted enrichment or leaning of the air/fuel ratio can optimize the degree of conversion of the catalyzer.
