    摘要： The invention relates to a protective system for a supercharged internal combustion engine. In normal operation, supercharging is set and/or regulated at a predeterminable reference value (P reference). There are various protective neasures in case of overcharging of the engine which act depending on the excess supercharging. In a first protective measure, the setting or regulation of the supercharging is cut out and an adjuster which affects the supercharging is set to a predetermined position. In a second protective measure, the fuel feed to individual cylinders is interrupted according to a predetermined cut-out programme. If this cannot adequately reduce the supercharging, other cut-out programmes with greater cut-out frequencies are introduced in succession.

    摘要： The description relates to a device for fault recognition in connection with a knock-detecting device in an internal combustion engine in which the sensor output signal is compared with a standard reference level depending on the rotation speed for knock detection. Depending on the result of comparison, knocking is detected and, when it is, knock-preventing steps are initiated. To prevent the internal combustion engine from running improperly in unacceptable operating conditions in the event of the failure of a knock sensor or its evaluation circuit, there is a continuous error detection process which checks whether the standard reference level lies within a permissible range depending on the rotation speed, where this range is either the permissible standard reference level band or a range between an upper limit (UGO) and a lower limit (UGU), both depending on the revolution speed. If the standard reference signal level leaves this range for a predeterminable time, a fault is detected and safety measures are initiated which remain operative until the refence level lies once more within the permissible range.

    摘要： The proposal is for a process for the adaptive knock control of an internal combustion engine designed to adjust the angular ignition spacing of an engine in the "delay" direction when knocking occurs and then in the "advance" direction. At the same time the engine is to have sub-divided operating ranges in which a delay value found during operation in a range is always stored when that range is left. Especially an average of all the angular ignition spacings issued in a range or a delay value added by a digital low-pass is to be stored hereby.
