Abstract
A system that automatically stops an engine when the vehicle is stopped and restarts the engine in response to a predetermined condition is disclosed. The system may generally include an engine and a motor for restarting the engine and driving an auxiliary machine when the engine is stopped, and an electrical power source for supplying electrical power to the motor. The motor may be disposed within a crank pulley housing and configured to be connected to a crankshaft. The motor may restart the engine in response to a predetermined condition. The system may include a gear reduction system for amplifying the torque provided by the motor. The motor may drive an auxiliary machine when the engine is stopped. The engine may drive the auxiliary machine when the engine is operating in drive.
