- Analysis of lubricant oil contamination and degradation and wear of a biogas-fed otto cycle engine Rovian Bertinatto Leandro Friedrich Reinaldo Aparecido Bariccatti Samuel Nelson Melegari de Souza Flavio Gurgacz Felix Augusto Pazuch Ingeniería biogas corrosion biomethane biodigester Contaminants The increasing deployment of biodigesters for the treatment of waste on farms and the use of the biogas generated in the produc tion of energy have highlighted th e need for knowing the influence of this fuel on internal combustion engines. This study aimed to analyze the influence of filtrated biogas on lubricant oil contamination and degradation, as well as on engine wear and corrosion. Lubricant oil samples were collected every 75 engine operating hours (EOH) and then correlated between each other and with a sample of new oil, determining the elements presen t in the biogas that contribute to lubricant oil contamination and degradation, as well as lubricant oil performance in the course of EOH and engine wear. The results demonstrate that hydrogen sulfide a ffects the performance of the lubricant oil and engine wear. Among the metals, we observed that the copper concentration exceeded the maximum limit recommended in the literature. As for the additive s, the variation in concentrations of magnesium impacted on lubricant performance. By monitoring lubricant oil quality were able to extend the engine oil change interval of this study by 50% , what resulted in a savings of 33.3% in the cost of lubricant per hour worked. 2017 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303252893004 en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
