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 Navicula 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 °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.

RuO2在柴油中的摩擦学行为：Benthic-硅藻Navicula sp。藻类生物柴油

与空转发动机相比，正在运转的汽车发动机在其滑动部件之间产生更大的摩擦力以及磨损，因此需要润滑以降低这种特殊的摩擦力。生物柴油肯定是柴油的替代可再生来源。目前的研究将测量底栖硅藻Navicula sp。的摩擦和磨损特性。藻生物柴油中含有不同浓度的RuO ₂。研究了生物柴油的各种混合物，例如B20，B20 + 50 ppm和B20 + 100 ppm。测试已在75°C下以1200 rpm的速度，每1 h 40 kg的平均负载进行。结果显示，随着生物柴油中RuO ₂纳米颗粒浓度的增加，摩擦和磨损降低。
