    • The invention relates to an internal combustion engine with several cylinders. At least one cylinder is configured as a reference cylinder to which an active cylinder pressure sensor is allocated. A passive cylinder pressure sensor is allocated to each of the remaining cylinders. At least one actuating member is assigned to the cylinders. A crankshaft angle sensor is provided. During the quasi-stationary operating mode (BZ STAT) of the internal combustion engine, the cylinder segment durations (T SEG i) which are allocated to the individual cylinders are equated, by means of an actuating member engaging in at least one actuating signal which is allocated to the respective cylinder. Furthermore, during the quasi-stationary operating mode of the internal combustion engine, the measuring signal (MS P CYL REF) of the active cylinder pressure sensor is allocated to the respective measuring signals (MS P CYL k) of the passive cylinder pressure sensors. As a result, an adjustment is made of the signal processing of the measuring signals (MS P CYL k) of the passive cylinder pressure sensors, depending on the respective measuring signals of the passive cylinder pressure sensors captured during the quasi-stationary operating mode (BZ STAT), and of the signal processing of the allocated measuring signal (MS P CYL REF) of the active cylinder pressure sensor.
    • 本发明涉及一种具有多个气缸的内燃机。 至少一个气缸被配置为参考气缸,活动气缸压力传感器被分配到该参考气缸。 无源气缸压力传感器分配给每个剩余气缸。 至少一个致动构件被分配给气缸。 提供曲轴角度传感器。 在内燃机的准静止工作模式(BZ STAT)期间,分配给各个气缸的气缸段持续时间(T SEG i)通过致动构件被等同,致动构件接合至少一个致动信号 被分配给相应的气缸。 此外,在内燃机的准静止工作模式期间,活动气缸压力传感器的测量信号(MS P CYL REF)被分配给无源气缸压力传感器的相应测量信号(MS P CYL k)。 其结果是,根据准静态运行模式期间所捕获的被动缸压力传感器的相应测量信号,对被动缸压力传感器的测量信号(MS P CYL k)的信号处理进行调整( BZ STAT)以及活动气缸压力传感器的分配测量信号(MS P CYL REF)的信号处理。
