STOP-START SELF-SYNCHRONIZING STARTER SYSTEM
First Claim
1. A starter system for an engine having a stop-start capability, the starter system comprising:
- a first gear coupled to the engine, such that the first gear rotates at a speed of the engine; and
a starter arranged relative to the engine, the starter having;
a second gear arranged to selectively mesh with and apply torque to the first gear in order to start the engine, wherein the second gear is capable of rotating at the speed of the engine; and
a synchronizer arranged to substantially match the speed of the second gear with the speed of the engine prior to engagement of the first and second gears, such that the second gear is enabled to mesh with and apply torque to the first gear to thereby start the engine.

Abstract
A starter system is provided for an engine having a stop-start capability. The starter system includes a first gear coupled to the engine, wherein the first gear rotates at a speed of the engine. The starter system also includes a starter arranged relative to the engine. The starter includes a second gear arranged to selectively mesh with and apply torque to the first gear in order to start the engine, such that the second gear is capable of rotating at the speed of the engine. The starter additionally includes a synchronizer arranged to substantially match the speed of the first gear with the speed of the engine prior to engagement of the first and second gears, such that the second gear is enabled to mesh with and apply torque to the first gear to thereby start the engine. The starter system and the engine may be employed in a vehicle.
