Abstract
A flywheel energy storage system for maintaining fan speed of a cooling fan on an internal combustion engine. The flywheel energy storage system allows a fan to rotate independent of the internal combustion engine and use energy stored in a flywheel for the continued rotation of the fan when a speed of the internal combustion engine falls below a predetermined speed. In this manner, the fan can provide an adequate air flow to cool the components of the internal combustion engine regardless of the speed of the internal combustion engine. To accomplish this, a fan is coupled to a clutch and a flywheel.
