Análisis tribológico en un motor de gasolina con dos marcas de lubricantes y la misma especificación

At present, the lubricant of a motor car is not taken with the importance of the case, causing consumers to give greater importance to the price of the same rather than quality, and components. Research conducted an analysis of oils through a tribological test in a gasoline engine, with the aim of knowing the wear on internal engine components, based on the damning limits and their established ranges. Two brands of SAE 20W50 API SN lubricant, was used to perform a comparative table between them and under the same conditions. Among the results, it was observed that the oil A has a higher percentage of soot generated 0.02% higher than B, for reasons of lower viscosity at high temperature. A substantial difference in amount of oxidation by a value greater than 27% in oil B, found what specifically affects the life of the lubricant and jeopardizes the protection of engine components. The amounts of Cu, Si and Al were within the limits damning both the lubricant and lubricant B was no substantial difference is these products. Instead Na values were outside the range (23 and 24 ppm) for coolant leaks. It is disclosed then that despite having the same specification between different brands, you can generate different wears due to internal components and characteristics of each oil type.
