Effect of addition of MWCNTs to a mineral lubricant on Diesel engine performance

In this research, a diesel engine lubricant, modified with Multi-Walled Carbon Nanotubes (MWCNTs) was evaluated. Carboxylic group functionalized MWCNTs were dispersed in 15W40 mineral oil for Diesel engines and retaining ring cylinder sleeve materials from F300 used tribological tests. The Nanofluid (0.1 0.5 1% wt.) rheological behavior characterized. Nanolubricants wt base evaluated on Pin-on-Disk test. Results suggest both wear rate coefficient of friction reduction when are used, while no significant properties changes observed.
