    • The invention relates to a method for regulating the lambda value of an internal combustion engine with a catalytic converter for subsequently treating the exhaust gases of the internal combustion engine, with a binary lambda probe, which is mounted upstream from the catalytic converter and which senses the composition of the exhaust gases. According to the invention, the lambda set value is superimposed with a lean/rich amplitude. This lean/rich amplitude has an integral component and a discontinuous component leading back to the lambda set value. When a change that differs from the change in the exhaust gas composition caused by the lean/rich amplitude is detected, the coefficient of the integral component is modified and/or a discontinuous component is added to the integral component or subtracted therefrom.

    • An internal combustion engine has at least one cylinder and an exhaust gas tract, in which an exhaust gas sensor, that can be heated in a controlled manner, is arranged. An exhaust gas temperature of an exhaust gas flowing in the exhaust gas tract is determined as a function of the heating power (P_HEAT) supplied to the exhaust gas sensor. An estimated value of the exhaust gas temperature is determined as a function of a physical model of the combustion of the air/fuel mixture and of the exhaust gas tract as a function of at least one operating variable of the internal combustion engine, but independent of the heating power supplied to the exhaust gas sensor. Model parameters of the physical model are adapted as a function of a deviation of the estimated value and of the exhaust gas temperature determined by the supplied heating power.
    • 一种内燃机具有至少一个气缸和排气道,排气传感器可以被控制地加热。 根据供给到废气传感器的加热功率(P_HEAT),确定排气管道中排出的废气的废气温度。 废气温度的估计值根据作为内燃机的至少一个操作变量的函数的空气/燃料混合物和废气道的燃烧的物理模型的函数来确定,但是与 提供给排气传感器的加热功率。 物理模型的模型参数被调整为由所提供的加热功率确定的估计值和排气温度的偏差的函数。

    • In order to average the continuously sampled individual values of the measuring signal through totaling over a summation period (TP1, TP2), said period corresponding to the period, dependent on engine speed, of pressure pulsations of the exhaust, while at the same time sparing the memory resources, it is proposed for totaling to be carried out across the N1 individual values block-by-block and already to start before signal updating so that the block values already formed continuously block-by-block up to the update time (tn) and buffered instead of the respective individual values are used for calculating an average.
    • 为了通过在总和周期(TP 1,TP 2)上的总计来平均测量信号的连续采样的各个值,所述周期对应于取决于发动机转速的周期的排气的压力脉动,同时 节省了存储资源的时间,提出了在逐个块的N 1个别值之间进行总计执行,并且已经在信号更新之前开始,使得块值已经连续地逐块形成直到更新 时间(t N n N)和缓冲代替各自的个别值用于计算平均值。
