摘要: 使用场发射扫描电子显微镜、X射线衍射、原子力显微镜、傅里叶变换红外光谱等手段,对采用电弧法生产的石墨烯A和采用氧化还原法生产的石墨烯B的微观结构和形貌进行表征,考察两种石墨烯作为添加剂对重负荷柴油机油CK-4 15W-40减摩抗磨性能的影响。采用四冲程柴油机台架试验评价添加石墨烯对油品燃油经济性的提升效果。四球机摩擦试验结果表明:两种石墨烯的引入均能起到减摩抗磨效果,加入石墨烯A后,钢球磨斑直径下降20.89%,油品摩擦因数下降35.58%;加入石墨烯B后,钢球磨斑直径下降13.08%,油品摩擦因数下降19.23%。燃油经济性评价结果表明,在高转速工况下,添加石墨烯A的重负荷柴油机油的有效燃油消耗率降低1.0%~2.5%。

Abstract: The microstructure and morphology of graphene A produced by arc method andgraphene B produced by redox methodwere characterized using field emission scanning electron microscopy, X-ray diffraction, atomic force microscopy, Fourier transform infrared spectroscopy, and other methods to investigate the effect of two graphene as additives on the anti friction and anti-wear properties of heavy-duty diesel engine oil CK-4 15W-40. Using a four stroke diesel engine bench test to evaluate the improvement effect of adding graphene on fuel economy of oil products. The results of the four ball machine friction test showed that the introduction of both graphene can achieve anti friction and anti-wear effects. After adding graphene A, the wear spot diameter decreased by 20.89% and the friction coefficient decreased by 35.58%; After adding graphene B, the wear spot diameter decreased by 13.08% and the friction coefficient decreased by 19.23%. The fuel economy evaluation results showed that adding graphene A to heavy-duty diesel engine oil under high-speed conditions can reduce the effective fuel consumption rate by 1.0% to 2.5%.
