Implication

Randomized trial evaluates the effectiveness of aluminum oxide nano-lubricants on engine cylinder liners, indicating improved wear resistance.

Key Points

This research aims to assess how aluminum oxide nanoparticles in engine oils affect wear and preservation of diesel engine cylinder liners.
Conducted wear testing with four lubrication conditions: original material, base oil, and base oil with 1 g or 2 g Al₂O₃ nanoparticles.
Employed multi-modal characterization techniques including X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and optical microscopy.
Analyzed the impact of nanoparticle addition on surface damage and crystal structure retention under operating conditions.
XRD analysis showed that the base oil led to crystal structure degradation, whereas oils with Al₂O₃ nanoparticles maintained crystal integrity, especially at 2 g concentration.
FESEM findings indicated that surface damage decreased with higher Al₂O₃ content, confirming improved durability.
EDS mapping revealed a protective Al₂O₃ tribofilm formation, especially in the 2 g/L formulation, minimizing iron exposure and oxidation.
