Abstract
An engine starting system ( ) includes a starter ( ) coupled to an engine ( ) through a rotational energy storage device ( ) such as spiral spring ( ). When electrical power is applied to the starter ( ), the rotational energy produced by the starter ( ) is stored in the rotational energy storage device ( ) allowing the starter ( ) to rotate which reduces electrical currents in the starter and stress on system components. The rotational energy is gradually transferred to the engine ( ) until the engine ( ) is rotationally self-sustaining.
