Dispositivo pino-disco para análise de desgaste na presença de diesel e biodiesel

Abstract

Since the biodiesel national programs began, many research groups have been studied this fuel efficiency, such as economical aspects, environments effects and engine performance and durability. The research objective was project and build a pin-on-disk device test per ASTM G99 95a (Standard Test Method for Wear Testing with a Pin-on-Disk Apparatus) to test material wear under diesel (B5) biodiesel (B100). The project validation was realized by performing aluminum-silicon wear test under two conditions: in presence of diesel (B5) and in presence of biodiesel (B100), with fix speed of 220 rpm, pin load of 5 N and 8 N during 150,000 cycles. The test analysis desired to compare the wear of an alloy used in diesel engines under different solutions. After the wear test, the disc weight loss, the topography and the microstructure were analyzed. The qualitative preliminary result shows better lubricates of biodiesel (B100) to test conditions adopted.
