摘要
A method for predictive maintenance of components of an internal combustion engine by a structure-borne sound sensor includes: recording vibrations of the components of the internal combustion engine by at least one structure-borne sound sensor; and during operation of the internal combustion engine, continuously checking a release for diagnosing a wear condition of the components of the internal combustion engine. The one or more structure-borne sound sensors, which are arranged at one or more positions on the internal combustion engine, record measurement signals and forward them to evaluation electronics. The measurement signals are time-synchronized to a characteristic state of the internal combustion engine or the measurement signal recording is time-triggered. The time-synchronized or triggered measurement signals are decoded into measurement data. The decoded measurement data is subjected to a signal transformation. One or more spectrograms are generated from the signal transformation.
