Abstract
The automotive and petroleum industries are facing difficult international competition, government regulations, and rapid technological changes. Ever-increasing government regulations require improved fuel economy and lower emissions from automotive fuel and lubricant systems. Higher energy-conserving engine oils and better fuel-efficient vehicles will become increasingly important with increasing emphasis on saving resources and reducing engine friction. Identification of industry research needs for reducing friction and wear in transportation are critical for improving fuel economy and extended vehicle reliability. There are hundreds of tribological components, from bearings, pistons, transmissions, and clutches, to gears and drivetrain components. The application of tribological principles is essential for motor vehicle reliability and energy conservation.
