Abstract

Owing to its low friction coefficient, nanosized MoS2 is as an excellent lubricant additive that can enhance the durability and efficiency of internal combustion engines. Herein, we investigate the application of MoS2-based materials as additives for a 10W-40 engine under different working conditions. To improve rheological and tribological properties, the heterogeneous nucleation was used to deposit MoS2 nanoparticles on surface of different carbon nanomaterials, such as graphene oxide, reduced graphene oxide, and carbon nanotubes, using an impinging jet reactor. Adding MoS2-based nanomaterials enhanced the rheological and tribological properties of the engine oil. At temperatures above 0 °C, adding hybrid materials decreased the friction factor between the engine oil and nanosuspension by up to 55%.
