Further, when the third start switch R3 is turned off, the super capacitor 22 and the spark plug are opened. After the shortest path between 34 forms an open circuit, the shortest path of the electrical circuit between the generator 33 and the spark plug 34 causes the spark plug 34 to use the generator 33 as the main power supply, and the battery 21 and the Super capacitor 22 provides auxiliary power .
