Engine flameout method

Abstract

The present invention relates to an engine flameout method, which is used on a motorcycle. The motorcycle includes an engine with a crankshaft, a battery, an integrated starter and generator system, and an engine control unit. The integrated starter and generator system includes a driving control device, an integrated starter and generator device and an angle sensing device, the driving control device is electrically connected to the battery and can receive the signal of the angle sensing device, the integrated starter and generator device is coaxially arranged with the crankshaft, and the battery and the driving control device are further electrically connected to a key switch, a driving and generating power switch, a power self-holding switch and an engine control unit. Wherein, through the engine flameout method of the present invention, each time the engine is flameout, the engine crankshaft angle can be stopped at the same position, and the next time the driver turns on the key switch to start the engine, the driving control device can directly control the integrated starter and generator device to rotate forward to start the engine directly at the optimal starting angle.
