Evaluation of applicability of dielectric constant in monitoring aging processes in engine oils

Abstract

In the era of developing technology, ICE forms the used sources applied to drive vehicles, machines and a variety of equipment. We can assume that despite its numerous drawbacks, ICE will remain to play the role of the dominant source of power for many years [9,12]. The lubrication system forms one of the most important systems in an engine, and a lubricating oil forms its integral part. In order to adequately verify the properties of oils during operation, there is a need to easily and accurately diagnose its quality. This fact leads to the need to adequately select a representative parameter by means of which it is possible to monitor changes occurring during its exploitation. Modern engine oils consist of various components and additives, by which a number of stringent operational requirements can be achieved and realized. Therefore, it is important to adopt and select such research methods and quantities that meet the requirements of a diagnostic parameter, can be applied to analyze the quality of the oil. The assessment of oil wear in an engine currently forms one of the most dynamically developing trends in research and is of interest to many scientific institutions [7]. This subject also forms the focus of interest of private companies operating vehicles due to the practical and economic outcomes that can be valuable to them [5,6]. All mechanisms or components of equipment are subjected to the processes of aging and wear so along with aging, engine oil changes its lubricating properties, which adversely affects the characteristics of the lubrication system.
