In a method for operating an internal combustion engine, a crankcase of the internal combustion engine has a vent into the intake section of the internal combustion engine, and upon outgassing of fuel out of engine oil present in the crankcase, the operating point of the internal combustion engine is modified so that the air-fuel ratio does not fall below a definable value.

Method for operating an internal combustion engine

A signal processing device and a control unit for cooperating with a signal processing device are described, the signal processing device being designed for processing knocking signals of an internal combustion engine which are provided by knocking sensors. A comprehensive check for errors is performed. The filter coefficients provided for a filter in the signal processing device are checked for consistency. Furthermore, messages between control unit and signal processing device are checked for transmission errors. If errors occur, alternate measures are initiated.

A method and a device for knock control of an internal combustion engine, in which an adjustment of the ignition angle takes place. When knocking occurs, the ignition angle is retarded and then advanced again. An increasing advance adjustment of the ignition angle reduces the rate of the advance adjustment.
