Tribological behaviour of RuO2 in diesel: Benthic-diatom Navicula sp. algae biodiesel

Abstract

An operating automotive engine generates more friction as well as wears in between their sliding parts when compared to an idle one, and so needs lubrication to lower this particular frictional impact. Biodiesel is surely an alternative renewable source of diesel fuel. The current research will measure the friction and wear characteristics of benthic-diatom <em>Navicula</em> sp. algae biodiesel with RuO₂ at various concentrations. The biodiesel was studied at various blends such as B20, B20+50 ppm, and B20+100 ppm. Tests had been carried out at a speed of 1200 rpm at 75 &deg;C under an average load of 40 kg per 1 h. Results revealed that friction and wear decreased with an increase in the concentration of RuO₂ nanoparticles in biodiesel.
