Abstract

Nowadays, the growing worldwide concern over a depleting mineral resources has made waste oil recycling a worthwhile research project to be invested in for the next decades. There are multiple researches involving the field of tribology on recycling waste engine oil that have been conducted. The standard process prior to each test is to filter the waste engine oil into a raw oil suitable for testing and study. ASTM D7317 is a standard process for filtering of waste engine oil that demonstrates good performance where the predicted filtered waste engine oil is free of contaminants and metals and serves as a benchmark for the development of portable oil filters. This thesis is to show the design, fabrication and analysis of this portable oil filtration unit designed to combat wastage of used oil. This thesis begins with the design development of a portable oil filtration unit by selecting the appropriate material and designing using various design modelling methods. This thesis then discussed solutions to technical problems encountered throughout the development of this concept of the portable oil filtration unit. The methods used to design, develop and fabricate the portable oil filter as well as analysing its performance was discussed in chapter 3 along with the computer aided analysis methods and usage of the software CATIA. This portable oil filtration unit was primarily designed to meet a vehicle's engine oil needs (about 5L) whilst allowing all types of oil to be filtered depending on the user’s needs. It was constructed out of nylon, following the method of the standard process of filtration. The filter was made of cellulose paper due to its resistance to pressure and high retention rate. The probable analysis of this product was made using CATIA before fabrication and subsequent experimental testing was carried out. Experimental results with low volume of oil showed that the filter initially was able to slightly reduce time taken for filtration process. However, subsequent testing with higher volume of oil showed that the filter did not keep up with the filtration time of laboratory unit. Based on this finding, the design did not meet the required criteria to compete with the laboratory filtration unit.
