EN The actual tendency to develop methods end techniques to diagnostic vehicles is making grow the interes f and the demand of the technical state analysis in exploration conditions, besides to systems, machines and devices more and more complex. The problem whit design and exploitation of modern machines and technical devices is to recognize the technical state in operational conditions [1-4]. To define the correct dynamic model and choose the best research method is the question of industry field, and the present paper has an approach about this topic. The coherence function which is the local measure of the similarity processes has, so the essential diagnostic properties in the reference to the objects which carry I will name linear and stationary in the field of the dynamic time. Yet the larger possibilities of uses of the diagnostic coherence functions can to find in mechanical arrangements non-stationaty or non-linear. The present methods of the diagnosing the condition of the folded objects combustion engines are which, are based on the measurements of the value steering currents. The vibrodiagnostic of combustion engines is the using analysis vibration processes generated in combustion engines the alternative method. Vibrodiagnostic enabling the opinion of the engine condition using the sensibility estimate the vibration process [l, 7-10]. The estimation of the combustion engine condition with sparkle ignition for the help of the research of vibration measures is possible thanks to utilization to the property of the coherence function [5, 6J. The implementation of software for needs: the acquisition of vibration processes, their processing, statistical inference and visualization - facilitates the leadership of investigations and the study of results.
