Study of tribological characteristics of continuous variable transmission oils

Reduction of friction and wear of moving parts in transmission is very important in order to get the best fuel efficiency and reduce loss of power. At all times, there must be fluid film to separate moving surfaces. Efficiency of fluid film depends on the tribological characteristic of its viscosity...
