The effects of lubricating oil on friction and engine-out emissions in a light-duty 2.2L compression ignition direct injection (CIDI) engine were investigated. A matrix of test oils varying in ...

Scientists from BP are applying molecular science in their laboratories to make the perfect oil blend to reduce engine friction and increase efficiency. According to the company, friction caused by ...

A new process for treating metal surfaces has been developed that has the potential to improve efficiency in piston engines and a range of other equipment. Researchers at Georgia Institute of ...

In automatic transmissions a smooth clutch operation is related to the velocity dependence of the coefficient of friction (COF). Although JASO M348 and other full-scale clutch tests, or other ...

The functional lifetime of a wet clutch can be characterized using wear characteristics such as velocity dependence of the coefficient of friction (COF) and friction curves. Current market trends ...
