Estudio comparativo característico de las propiedades técnicas del lubricante utilizado en el transeje de un vehículo híbrido toyota prius

Abstract

The notable increase in hybrid and electric vehicles in Ecuador has addressed the issues of excessive fuel consumption and the pollution associated with traditional vehicles. This transition has positively impacted the country’s automotive industry, effectively meeting mobility and environmental demands. Considering this, the study was carried out to evaluate the conditions of various oil samples. Analysis processes were implemented to understand the behavior of these samples, obtaining values that allowed us to distinguish the oil’s useful life. A total of 12 samples were analyzed, of which 11 corresponded to used lubricant and 1 to virgin lubricant. Inherent properties were obtained through this study, including density, dielectric constant, water content, and oxidation level. Graphs were used to plot the established limits, to carry out the lubricant degradation study calculated by taking the baseline corresponding to the new oil as a reference. This allowed us to observe the behavior of each variable over time. As a result, it was concluded that the deterioration of the lubricant was mainly manifested in the presence of water and the loss of dielectric constant, which was notable after 72,000 kilometers of use. Based on the results, it was recommended to replace the lubricant once 70,000 kilometers of use was reached and to take samples more frequently, as well as to keep a more detailed monitoring of the vehicle. This approach will allow for more effective detection and addressing of lubricant-related issues, consequently optimizing engine performance and useful life. motor.
