... prepared. Under harsh conditions, lubrication properties of TSs-SACT were investigated. The results showed that the vibrations of frictional forces and loads of TSs-SACT with the best antifriction performance were suppressed. The curves of instantaneous frictional forces of TSs-SACT were the smoothest...

... is responsible for decreasing the natural lubricating compounds in fossil diesel. Then, it results in the low lubricity of fossil diesel which increases friction and wears scars on the metal surface of machinery components. Therefore, it is necessary to use additives to improve the lubricity properties of fossil...
