Claim Text:
1. A stop control system for an engine comprising: a motor connected to a crankshaft of an engine; and a control device that stops the crankshaft in a compression stroke by temporarily driving the motor to thereby assist rotation of the crankshaft that is still being forwardly rotated after starting stop control of the engine under predetermined engine stop conditions and before stopping rotation of the crankshaft, wherein the control device is configured to monitor an angular speed of the crankshaft and assist the rotation of the crankshaft until the angular speed becomes equal to or greater than the angular speed at which the crankshaft reaches the compression stroke and smaller than an angular speed at which the piston moves through the compression top dead center by temporarily driving the motor at a time when the angular speed of the crankshaft is smaller than an angular speed at which the crankshaft reaches the compression stroke.
