Abstract

A starting system includes an energy-storing hub assembly and a final member being operative to rotate about a first rotational axis. The energy-storing hub assembly includes an energy-storing hub and a resilient member, the resilient member being connected to the energy-storing hub and the final member. An electric motor is also provided to rotate the final member. Further, a locking member is configured to selectively lock the energy-storing hub such that energy is accumulated in the resilient member. Moreover, an energy-release cam is arranged to actuate the locking member such that the energy-storing hub is unlocked, thereby releasing the energy accumulated in the resilient member. Consequently, the energy-storing hub rotates and starts the internal combustion engine.
