Abstract
In an externally ignited internal combustion engine with a knocking sensor which comprises a membrane to absorb the vibrations of the engine housing during knocking of the internal combustion engine, cooperating with a vibration absorber, whereby the membrane is formed by a thin walled location of the engine housing or by an opening in the wall of the engine housing which is closed by a membrane plate. The knocking sensor can be mounted at an easily accessible location and it is also assured that the resonance characteristic of all internal combustion engines of a series are the same at the location scanned by the knocking sensor.
