Impact of diagnostics state model to the reliability of motor vehicles

Abstract

This paper presents the model of diagnosis of the condition in order to maximise the reliability of motor vehicles and their availability to work. The studied model of the reliability condition diagnosis of motor vehicles included the most important parameters of the theoretical and experimental analyses. Analysis of its formation is based on the recordings of total failures of integral components which are in the function of the parameters observed in the condition diagnostics of motor vehicles components. The research included failures that occurred under the influence of increased operating temperatures and worn-out of bearings (stable, flying and sliding) on the crank and camshaft, all in order to provide better insight into the problem. By reliability analysis, we conclude that it is in parallel collusion with authoritative reliability of motor vehicle which is determined and depends on the observed increase in diagnostic parameters: temperature and worn-out of bearings.
