    Análisis estadístico comparativo de propiedades de aceites lubricantes usados en motores de combustión interna de una planta de generación eléctrica
    (Instituto de Tecnologia, 2022) MARTÍNEZ OLIVARES, Adriana Cecilia; LORENZO ZÁRRAGA, Marcos Daniel; SALAZAR MARTÍNEZ, José Enrique
    This work presents a comparative statistical study of the physicochemical properties of used lubricating oil samples from internal combustion engines in an electric power generation plant. The analysis is based on laboratory tests performed on 44 samples to determine the statistical significance of differences between oil brands and their relation to usage time. Normality tests, analysis of variance (ANOVA), and Tukey tests are used, revealing significant variations in properties such as viscosity, acid number, and metal content. The results support the hypothesis that lubricant performance depends on both the brand and the operating conditions.

    Analysis of lubricating oil in internal combustion engines of electrical power generation plant. Subtítulo: Análisis de aceite en motores de combustión interna estacionarios de planta de generación de energía eléctrica.
    (Instituto de Tecnologia, 2014) POZO-MOREJÓN, Juan A.; MARTINEZ-JIMENEZ, Boris L.; RODRÍGUEZ-RICO, Iván L.; MARTINEZ-MARTINEZ, Reinaldo; HERRERA-ARTILES, Arnaldo M.; LEITE, Jandecy Cabral.; BATISTA, Clauderino da Silva
    This study implements an integrated analysis procedure for lubricating oil in stationary diesel engines of an electric power generation plant, using the SACODE methodology with modifications to variable limits and evaluation of kinematic viscosity and TBN through Fuzzy logic. The method was automated by the SOFTLUB software, developed in MATLAB, enabling the monitoring of historical parameters, predicting future behaviors, and supporting maintenance decision-making.

    Aspectos Importantes na Utilização de Bombas Centrífugas em Velocidade Variável para a Redução do Consumo de Energia
    (Instituto de Tecnologia, 2006) MESQUITA, André L. Amarante; SILVA, Lázaro J. S. da; ABRAHAM JÚNIOR, Otávio; PEREIRA, José Almir; R. SILVA, Aldo Cezar P.; BATISTA, Clauderino da Silva
    The study examines the use of variable speed centrifugal pumps as a solution to reduce energy consumption in water supply systems. It covers theoretical principles, technological aspects, and economic feasibility, employing frequency inverters to adjust flow according to demand. Two case studies illustrate the method's effectiveness: parallel pump operation and tank level control. Results show significant energy savings with short financial payback, emphasizing the need for technical and economic analysis for implementation.
