Quantitative Analysis of Spectroscopy's Study for Engine Oil Degradation Monitoring Due to Temperature Effect

This paper presents the quantitative analysis of spectroscopy measurement for engine oil degradation prediction due to the temperature effect. The main objective of this project is to study the behavior of engine oil if the continues high temperature are applied to the engine oil as compared to the effect of running condition. Two types of engine oil were used as samples in this project from grade SAE 10W40 and 20W50. The experiment was done by heating the engine oil with inductance coil at 100oC for 5 minutes and then cool it about half an hour before continue heating for other 5 minute. This process repeat continuously until 100 minutes and samples were taken at every 10 minutes after cooling process. A spectrometer is used to measure the percentage reflectance of the samples. Data was arranged and analyzed in order to predict the degradation of the engine oil. The data will be used to develop an optical sensor for signal processing in monitoring the engine oil degradation.
