Kukurudziak Y. Development and realisation of a vehicle engine ignition system automated diagnostics method on the basis of comparison of signal

Object of Investigation. working processes of the ignition systems, which are changed during maintenance and determine the technical state of the automobile engine. Purpose of Investigation. is the working out and scientific basing of the method of automatized determination of the technical state of the engine ignition system in the conditions of maintenance of transport means. Methods of Investigation. method of physical and mathematical modelling, method of spectral analysis and synthesis of figure filters, method of engineless and motor tests, method of mathematical statistics. Apparatus: the devise for checking and apparatus processing of analogue signals of voltage, computer technique. Theoretical and practical results: carried out the modelling of the technical state of the ignition system, worked out algorithm and ensuring of diagnosing of systems in the conditions of maintenance, worked out the algorithm of creation and replenishment of the base of the given parameters which describe the technical states of the ignition system. Novelty: Suggested a new scientific approach to the determination of disrepairs of the ignition system by means of the analysis of the influence of these repairs upon some diapasons of the primary circle, suggested the model of the process of diagnosing of the ignition system. by means of comparing the parameters of spectral density of power of investigated and standard signals. Degree of Inculcation: inculcated at the joint-stock company (Ltd) "Vinnitsa Fleet of Taxis" and in the educational process of the automobiles and transport management chair of the Vinnitsa National Technical University. Sphere of the use: automobile transport.
