Investigations on Friction Losses within Front End Accessory Drives 2010-36-0178
In order to increase the efficiency of internal combustion
engines, Schaeffler Technologies recognized that it is necessary to
identify the sources of energy losses, quantify such losses and to
study ways to minimize them.
Based on this premise, the Front End Accessory Drive parameters
had to be investigated to locate where further potential
enhancement is hidden.
This paper aims to analyze and discuss about the main sources of
energy losses occurring in FEAD and propose ways to optimize the
system to the optimal range of efficiency and durability.
Investigations showed that there are some loss points of the
basic belt drive components which have good potential to be
reducible, e.g., losses at bearings and belt.
