Analysis of the Influence of Contamination in Lubricant by Biodiesel in a Pin-On-Disk Equipment

The introduction of biodiesel to commercial diesel is being increased every year. need check this addition the engine and lubricant important for automakers internal combustion manufacturers. oil analysis technique a type predictive maintenance, done by collecting from equipment analyzing it later in laboratory, or directly continuously on-line systems. In engines, all parts have pre-established service life, longer shorter, according specific function assigned it. By oil, condition these can be monitored. oils reveals first signs wear component. identification made based on study number particles, size, shape composition thereof, present samples, which provide accurate information about conditions moving surfaces without disassemble assembly belongs. work contamination biodiesels were simulate possible scenarios within an engine.The recommended manufacturer was “contaminated” with different percentages types biodiesel. After “contamination” they placed pin disk device under certain conditions.Through analyzes lubricants extracted Pin Equipment after tests, some carried out order effects using engine.These consisted Flash point, analytical ferrography, monitoring ferrous particles generated, viscosity, viscosity index, basicity index X-ray spectrometry.Among results obtained observed that 5% animal there increase index. Conversely, + vegetable decreased relation Diesel B5. We also found additions not detrimental at mix ratios test used.
