Study of Tribological and Thermal Properties of Engine Lubricant by Dispersion of Aluminium Nano Additives

Abstract

This study is experimental investigation of the tribological and thermal properties of aluminium and aluminium oxide nano particles immersed in engine lubricating oil. SAE20W40SL oil was used as base oil in which aluminium and aluminium oxide nano particles in size of 50 nm at the concentration of 0.2% and 0.1% were disseminated. Ultrasonic bath was used for the dispersal of the nano particles in the base oil. Pin-On-Disk apparatus was used for the measurement of the frictional force and wear rate of the lubricant. The results indicated a reduction in frictional force by 52% and 28% by aluminium and aluminium oxide nano lubricants at 0.2% concentration. The thermal conductivity test result showed an increase in thermal conductivity by 4.8% and 2.3% while using aluminium and aluminium oxide lubricants at 0.2% concentration. A reduction in the wear rate and viscosity of the lubricants was also seen while using nano particles.

Influence of the Viscosity of Nanofluids on Surface Roughness in End Milling of Nickel Alloys with Minimum Quantity Lubrication

“…The viscometer gave results whenever the applied torque fell within the 10 % and 100 % range with different spindles and speed combinations [10]. Using the KD2 Pro Thermal Properties Analyzer, the thermal conductivity of the lubricants was evaluated at a room temperature of 30 °C [11].…”

Comparative Analysis of Soft Computing Models for Predicting Viscosity in Diesel Engine Lubricants: An Alternative Approach to Condition Monitoring

“…Lowviscosity lubricants can result in an increase in the friction coefficient and wear, 12,13 while the utilization of certain additives or nanoparticles can lead to a reduction in frictional force and wear rate. 14 The investigation aims to explore alternative fuels derived from bioresources, specifically by blending palm oil with aluminum oxide nanoparticles. In this study, palm oil biodiesel is combined with Al 2 O 3 nanoparticles using ultrasonic techniques to evaluate their influence on the performance and exhaust parameters.…”
