Tribological behavior of the boron succinimide on cylinder liner and piston ring surfaces

In this study, tribological performances of two types of anti-wear additive, boron succinimide anti-wear package and ZnDTPs, were investigated in the cylinder liner and piston ring tribological system with a reciprocating tribotest machine. The tribological performances of oils were evaluated in three main contexts including wear rates, surface tribofilm formation and friction. Results showed that NP-3 (boron succinimide containing) lubrication oil which was environment and catalyst friendly, can be an alternative lubrication oil with its tribological performance due to its friction and wear reduction capacity.
