The paper contains application of operational modal analysis in use of combustion engine chosen technical state identification. The combustion engine No. 138C.2.048 with 1.4l. swept capacity, power 55 kW, generally applied to Fiat was the investigation object. It makes possible to introduce generated vibration signals as well as the investigation of his adjustment influence on the combustion engine vibration signals change. Conducted researches of combustion engine depended on delimitations of vibroacoustics measures for fit engine and comparison of this measures, with measures appointed for damaged engine (e.g. damaged injector) and accomplishment the assessment of received results influence on engine state by operational modal analysis. The present research use vibration methods as Operational Modal Analysis to recognize the technical state of the system.
