摘　　要：在内燃机油中分别加入不同比例的生物柴油和矿物柴油,采用四球摩擦磨损试验机考察了生物柴油和矿物柴油对内燃机油抗磨性能的影响。结果表明,内燃机油中加入生物柴油和矿物柴油后,抗磨性能变差,不同原料制备的生物柴油对内燃机油抗磨性能的影响无明显差异;此外,加有生物柴油和矿物柴油的内燃机油在高温氧化后抗磨性能进一步降低,其中加有生物柴油的内燃机油氧化后抗磨性能降低更为明显。The effect of biodiesel on antiwear property of engine oil was discussed. Different percentages of biodiesel and petrodiesel were incorporated into diesel oil, and antiwear performance was evaluated on a four-ball wear tester. The results indicate that the antiwear ability of diesel oil decreases when blended with biodiesel and petrodiesel. The influence of biodiesel of different origin on antiwear property of diesel oil is not significant. The antiwear ability of diesel oil with biodiesel and petrodiesel becomes poorer after oxidation than that before oxidation.
