    • During the measurement of the oxygen storage capacity of an oxygen storage system, which is assigned to a catalytic converter, a switchover operation from lean to rich exhaust gas or vice versa is effected. The measurement signals of a lambda probe are recorded; and an integral calculation is carried out over a time interval on the basis of the measurement values. Whereas in the past the start of the time interval was the point in time of the switchover operation, the present invention provides that the start of the second time interval is determined on the basis of the measurement signals of the second lambda probe i.e., the point in time is preferably fixed at the time at which these measurement values reach an extreme value. This design allows the oxygen storage capacity to be measured even if the lambda probe is not fully functioning totally correctly.
    • 在分配给催化转化器的氧气存储系统的储氧能力的测量期间,实现从贫燃料到富排气的反转操作,反之亦然。 记录λ探测器的测量信号; 并且基于测量值在时间间隔上执行积分计算。 而在过去,时间间隔的开始是切换操作的时间点,本发明提供了第二时间间隔的开始是基于第​​二个λ探测器的测量信号来确定的,即该点 优选地在这些测量值达到极限值的时刻固定。 该设计允许测量氧气存储容量,即使λ探针的功能完全不正确。
