ANÁLISE DE ÓLEO LUBRIFICANTE UTILIZADO EM MOTOR DIESEL DA MARCA FIAT DUCATO MODELO MULTIJET ECONOMY

Abstract

This work aims to perform the analysis of “used” lubricating oil used in diesel engines of vehicles used in the rescue activity of the Military Fire Department of Minas Gerais, specifically two Fiat Ducato Maxicargo diesel vehicles currently used in the 9th. ° Fire brigade of the city of Varginha. This analysis comprises the predictive maintenance system in internal combustion engines through the analysis of the lubricating oil used, as it is possible to verify the existence or not of solid particles that indicate the conditions of friction and internal wear of the engine. An internal combustion engine has about 200 moving internal components that work together under aggressive conditions under high pressure and temperature. Thus, to obtain maximum performance, it is necessary that the whole mechanical system acts friction free, using for this purpose the lubrication system. However, component wear is inevitable, and measurement of such wear can be accomplished by analyzing the lubricating oil.
