| ABSTRACT |
|
Lubricants, such as any types of greases and oils, are usually used to reduce the effect of friction. However,
they also have multifunctions that increase the overall performance and application life. To clarify how lubricants decrease
friction and reduce friction-related issues, this study evaluated the performance of specific fuel consumption and exhaust
emissions (such as hydrocarbon, carbon monoxide, and particulate matter) of motorcycle with nanosilica (nano-SiO2) added
to the original lubricant. Lubricants with 0.5, 1.5, 2.5, 3.5, and 4.5 wt.% nano-SiO2 were evaluated after testing their basic
properties and conducting tribology tests. The lubricant with 3.5 wt.% nano-SiO2 was the best candidate for the four-stroke
engine motorcycle experiments. The results of the tribology experiment with nano-SiO2 lubricant showed that the abrasion
loss corresponding to the 3.5 wt.% nano-SiO2 lubricant decreased by an average of 42.43 %. Overall, the 3.5 wt.% nano-SiO2
lubricant improved the effect of lubrication. The primary focus of the current study was the development of nano-SiO2
lubricant technology for applications in industry environments. |
