Abstract
The automobile industry is a vital part of the global economy, yet it faces numerous challenges and rapid technological change. Improved engine efficiency has an essential target for automobile industries to curb the increasing climate change and greenhouse emissions. Hence, fuel efficiency may be increased by minimizing energy losses from the engine. Tribology analyzes the effects of friction and wear, as well as lubrication on energy losses in engines, transmissions, and drivelines. Among the various approaches to improving engine efficiency, the tribologists and lubrication engineers focused mainly on reducing engine friction as a vital and economical method. The efficient lubrication of moving engine components with the least or no unfavorable effect on the environment is essential to lessen friction and wear. Improvements in various tribological engine components could lower fuel consumption, exhaust emissions, maintenance costs, and greater engine power and longevity. Previous studies carried several investigations on different surface textures/morphologies to evaluate their tribological properties in dry and lubricated conditions to optimize engine efficiency. This chapter delivers a comprehensive summary of automotive tribological components, and presents studies of lubricants. Finally, there is a discussion of a few application examples of tribology in the automotive industry.
