    • Disclosed is an internal combustion engine comprising at least one cylinder and an exhaust manifold in which a catalytic converter, a first exhaust gas probe, and a second exhaust gas probe are disposed. The first exhaust probe is located upstream from the catalytic converter while the second exhaust gas probe is arranged downstream therefrom. A lambda Controller is provided which is configured so as to determine a lambda correction factor in accordance with a first test signal that is assigned to the first exhaust gas probe. A trim controller is provided to which a setpoint value and an actual value of a second test signal allocated to the second exhaust gas probe are fed as a control difference. The trim controller is configured so as to determine a proportionate corrective factor. A control signal unit is embodied so as to determine a control signal for apportioning fuel into the cylinder in accordance with the lambda correction factor and additionally determine the control signal for apportioning fuel into the cylinder according to the proportionate corrective factor in a diagnostic mode of a component associated with the exhaust manifold.
    • 公开了一种内燃机,其包括至少一个气缸和排气歧管,其中设置有催化转化器,第一排气探针和第二排气探针。 第一排气探针位于催化转化器的上游,而第二排气探针位于其下游。 提供λ控制器,其被配置为根据分配给第一排气探针的第一测试信号来确定λ校正因子。 提供一个微调控制器,其中分配给第二排气探针的第二测试信号的设定点值和实际值作为控制差进给。 配置调整控制器以确定比例校正因子。 控制信号单元被实现为确定用于根据λ校正因子将燃料分配到气缸中的控制信号,并且另外确定用于根据在诊断模式中的比例校正因子将燃料分配到气缸中的控制信号 与排气歧管相关联的部件。
