Abstract
A starter assist device for an engine has a first rotatable member for rotating a shaft of the engine in a starting direction. The starter assist device also has a second rotatable member arranged to rotate relative to the first rotatable member in a non-starting direction, and further arranged to rotate in conjunction with the first rotatable member in the starting direction. The starter assist device includes an energy transfer assembly having a torque supply for rotating the second rotatable member in the non-starting direction and an energy storage mechanism arranged to alternately store and release a quantity of energy used when rotating the second rotatable member in the non-starting direction. The energy storage mechanism is arranged to release the quantity of energy to rotate the second rotatable member in the starting direction, thereby causing the first rotatable member to rotate the shaft of the engine.
