Internal combustion engines friction reduction is needed to fit stringent fuel consumption and emission regulations.
For this purpose, best solution is to optimize engine mechanical joints with right dimensions. As best friction reduction solutions are already used, future friction benefits will result from the sum of many small benefits from various technologies.
Trends are given on some design parameters: lubricant, loads, kinematics optimization and some technologies: surface finishing, coatings.
Some challenges on future engine design and manufacturing process are exposed.
