Abstract

The main purpose of this research is to study the oil based condition monitoring and its implementation on maintenance of automobiles engine, in this case, UTeM student bus. Oil based condition monitoring is conducted to determine the condition of the lubricant and evaluate whether or not the oil is suitable for further use. The current maintenance procedures applied on UTeM student buses are time based maintenance and maintenance based on mileage. However, both procedures can jeopardize the overall efficiency of the maintenance. In this study, oil based condition monitoring is performed to the lubricant of UTeM student bus and proves if it is the effective maintenance procedure to be applied. Viscosity, flash point and wear debris are selected as the parameters to be analyzed. Experimental method is used to analyze the lubricant of UTeM buses. Both fresh (new) oil and used oil of the UTeM student bus is examined for each parameter. This study uses three types of test methods; ASTM D93, ASTM D6595 and by using heated kinematic viscometer. The result of the analysis indicates that there are only two samples that exceeded the limit of ±15% of kinematic viscosity. Also it can be observed that the flash point decreases which indicates fuel dilution. It is suggested that oil change is carried out if the flash point is depressed to less than 170°C. The result on wear debris and analysis on the five elements shows a normal wear and depletion of additives characteristic. It can be concluded that there is definite significant in the comparison of mileage based maintenance and condition based maintenance by oil analysis. Condition based monitoring is proven to be more effective as maintenance system due to its accurate
