Although noise and vibration measurements are widespread in the machine diagnostics, they are not usedin the diagnostics of the powertrain of motor vehicles. Our research aims to investigate the possibilities, advan-tages, and drawbacks of using noise and vibration diagnostics performed for motor vehicles. In this paper, weattempt to use vibroacoustic signals from a motor vehicle for diagnostic purposes. Ordinary audible malfunc-tions, for example, misfiring in a passenger car, were artificially created. The differences between the normaland faulty operating conditions were examined to identify evidence of failure in the vibration signal. Primarily,evaluation through Fourier transformation was performed to provide a visual correlation between the fault andthe vibration behavior of the car. Detailed conclusions from the measurements and future research plans arediscussed.
