Optical behavior of transmission oil lubricant for degradation monitoring

Abstract

The demand of on-line monitoring for lubricant oils are increasing in recent few years cause of the awareness of used engine oil pollution and economic factors. Therefore, many studies have been done to support the demand of the monitoring system and the current trend was focusing on the optical behavior of the lubricant by using spectrometer. In our research work, UV/VIS Spectrometer was employed to analyze the optical behavior of lubricant and the relation with real parameter of lubricant such as oxidation, Total Acid Number (TAN) and contamination. The sample of used transmission oil was taken in real time and based on different mileage. With the combination of spectroscopy method and statistical analysis, the main parameters in lubricant monitoring properties including TAN and contamination can be determined quantitatively. The result in this article shows that the lubricant degradation can be monitored by using spectroscopy approaches by determining the correct wavelength.

“…They proposed a model that permits to reduce the total pump operation cost by forecasting the reliability index (RI) of its maintainability [10]. In their research, Idros et al (2011) found that UV/VIS Spectrometer was employed to analyze the optical behavior of lubricant and its relationship with real parameter of lubricant such as oxidation, Total Acid Number (TAN) and contamination. They stated that, with the combination of spectroscopy method and statistical analysis, the main parameters in lubricant monitoring properties including TAN and contamination can be determined quantitatively and the lubricant degradation can be monitored by using spectroscopy approaches through determining the correct wavelength [11].…”

Jiang et al's (2015) study aimed at developing a comprehensive simulation tool to model the lubricating gap flow between the piston and cylinder, which consists of a main flow model according to a lumped parameter approach and a numerical model for piston/cylinder interface.…”

Nanotechnology in Lubricants: A Systematic Review of the Use of Nanoparticles to Reduce the Friction Coefficient

“…Lubricating oil is a fundamental component for the correct functioning of vehicle engines today; therefore, it is one of the areas with the greatest research and innovation within the automotive industry [1][2][3][4]. This is mainly due to the functions that it performs, among which the following stand out: reduces friction [5], improves sealing [6], protects against wear and reduces corrosion [7], eliminates contaminants [8] and dissipates heat [9]. It is estimated that 80% of mechanical failures are caused by a wear defect due to friction and lubrication [10].…”
