Subjective feeling of ride comfort is important for today's cars. Random burst shaking while the car engine is running at idle is a phenomenon that is very disturbing for drivers. This phenomenon is a sign for suspicion customers that something is wrong. Engine vibration measurements and consequent assessment of an engine trajectory shape are dealt with. The measurement system was instrumented by the signal analyser PULSE. Time history of vibration was split into time interval corresponding to the engine double revolutions. The time records were improved by filtration in the frequency domain using the Fourier transform. The analysis results in planar orbit plots of the engine point where it is attached to the absorber.
