Studies of the lubrication of machine elements have been undertaken at the University of Leeds for over a century. Coincidentally the automobile has been part of our lives for a similar period. The ability to analyse in some depth the important frictional components of the internal combustion engine was significantly enhanced by the advent of the digital computer which became generally available around 1960, a few years before the word Tribology was coined.

In the last thirty years lubrication analysts and experimentalists have turned their attention successively to examination of engine bearings, piston assemblies and valve trains. The energy crisis of the mid-1970s stimulated an increased awareness of the scarcity of our natural resources for power generation and the need for their efficient use. Concurrently, there has been a growing recognition of the fragility of our environment and associated pressures through the green lobby to reduce emissions of noxious oxides, particulates and greenhouse gases. Through fuel consumption and exhaust considerations the automobile is a significant factor on a global scale in both these areas.
