Abstract
A starting system for an engine of a vehicle includes a starter motor and a motion control mechanism. The starter motor includes a starter pinion gear configured to selectively mesh with a primary mass of the engine. The starter pinion gear is selectively rotatable about a first axis of rotation to cause the primary mass to rotate about a second axis of rotation. The motion control mechanism includes a mechanism pinion gear that is configured to selectively mesh with the primary mass of the engine. The mechanism pinion gear is configured to rotate about a third axis of rotation in response to rotation of the primary mass about the secondary axis of rotation.
