The technology provides a reliable and modern way to investigate the quality of oils without having to be separated by long and expensive separation methods of oil components earlier to analysis or measurement.\u00a0In this study, a number of different samples of new and used engine oils available in the Iraqi commercial market (foreign and Iraqi-made) were analyzed. This method can also be used to identify the counterfeit brands of motor oils and to recognize the quality of these oils.\u00a0The above claims and characteristics have been achieved to design this new model by working with high scientific accuracy and great patience in making the new lubricants inside the internal combustion engines to give the highest 100% fluorescence intensity without loss of this intensity by the quenching factors, then the intensity will progressively decreases with the increase of oil consumption as a result of the operation of engines and consumption of new oil, and accordingly the appropriate applicable model was designed for this idea.\u00a0To prove this in practice and laboratory, the optimal conditions for many variables those may affect the design negatively or positively of this model have been established for the purpose of applying it efficiently and under different circumstances.<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" Inventor: Assist.
