Abstract This paper is to evaluate and compare the tribological properties of lubricating oil blends added with nano graphene and lubricating oil blends added with cerium oxide (CeO2) on the key friction pairs of the diesel engines. The dispersion stability is the premise of studying the tribological properties. In this paper, nano-CeO2 particles were self-made and high-quality nano-graphene was purchased. The dispersion stability of the two nanomaterials in lubricating oil was studied after the same modification respectively. According to the working conditions of the cylinder liner and the piston ring, the friction and wear tests of the lubricating oil blends added with the modified nanomaterials were carried out at the different temperatures. The results showed that the oleic acid and the stearic acid modified the two nanomaterials successfully. The dispersion stability of the modified nanomaterials in lubricating oil was improved. The dispersion stability of the lubricating oil blends added with graphene before and after modification was slightly higher than that of lubricating oil blends added with CeO2 before and after modification, respectively. At the high temperature, the anti-friction property of the two nano lubricating oil blends was similar. At the ambient temperature, lubricating oil blends added with modified CeO2 did not play a role in reducing friction, while lubricating oil blends added with modified graphene had the effect of reducing friction. Whether at ambient temperature or at the high temperature, the anti-wear property lubricated with lubricating oil blends added with modified CeO2 within the right concentration range was better than that lubricated with lubricating oil blends added with modified graphene.
