| Abstract:In order to solve the problems of injector wear failure caused by poor diesel tribological properties caused by deep desulfurization process， as well as large particle size and poor dispersion of nano additives， ultra-small particle size （1~2 nm） cerium oxide nanoparticles which have excellent dispersion in diesel were prepared. As a 0# diesel additive， its tribological and combustion properties were tested by a four-ball testing machine and an automatic calorimeter. The results show that the addition of cerium oxide nanoparticles to diesel fuel can enhance its anti-friction and anti-wear properties， reduce the wear scar diameter by about 13%， reduce the coefficient friction by about 27%， and increase the heat value of combustion by about 16% compared with 0# diesel. |
