Lubrication has become essential in enhancing engine efficiency in the era of rapid globalising. The tribological, oxidation and thermal conductivity properties of an engine oil play a vital role in improving the quality of a vehicle's engine life. In this research, molybdenum disulfide (MoS) nanoparticle was synthesised via a microwave hydrothermal reactor. Later, the nanoparticles were dispersed in SAE 20W50 diesel engine oil to formulate the nanolubricant. The results show that nanolubricant with 0.01 wt% MoS concentration showed the coefficient of friction, average wear scar diameter decreased by 19.24% and 19.52%, respectively, compared to the base oil. Furthermore, the nanolubricant with 0.01 wt% concentration of MoS nanoparticle showed an enhancement of 61.15% in oxidation induction time in comparison to the base oil. Furthermore, MoS addition within the base oil demonstrates a ~ 10% improvement in thermal conductivity compared to the base oil.
在全球快速全球化的时代，润滑对于提高发动机效率已变得至关重要。发动机油的摩擦学、氧化和热传导性能在提高车辆发动机寿命质量方面起着至关重要的作用。在本研究中，通过微波水热反应器合成了二硫化钼（MoS）纳米颗粒。随后，将纳米颗粒分散在SAE 20W50柴油发动机油中以配制纳米润滑剂。结果表明，与基础油相比，MoS浓度为0.01 wt%的纳米润滑剂的摩擦系数、平均磨斑直径分别降低了19.24%和19.52%。此外，与基础油相比，MoS纳米颗粒浓度为0.01 wt%的纳米润滑剂的氧化诱导时间提高了61.15%。此外，与基础油相比，在基础油中添加MoS后热导率提高了约10%。
