The changes of vibration estimators as a result of engine maladjustment, waste, damage or failure are the main idea of vibrodiagnostic investigation. Diagnostic investigations that use of vibration to determine the technical state of combustion engines are very difficult. Only a few proposed methods could have a wider technical use in diagnostics. This paper showes the validation of research results of the use of the Singular Value Decomposition (SVD) method. The research object is combustion engine No. 138C.2.048 with 1.4l. swept capacity, power 55 kW / 75 KM, generally applied to Fiat. It is possible to introduce generated vibration signals as well as the investigation of its adjustment influence on the combustion engine vibration signals change. Thanks to SVD methods, it is possible to decide which symptom given in the observation matrix is the best to recognize the technical state of combustion engines. The results that are introduced in this paper are only the part of realized investigative project and they do not describe wholes of the investigative question, only chosen aspects.
