1. The gasoline engine injects fuel into the combustion chamber through the fuel supply system, and after ignition, it is burned to produce gas at high temperature and high pressure.
2. The piston moves downward as the combustion gases expand, causing the connecting rod, crankshaft and other mechanical components to rotate together.
3. The rotation of the crankshaft causes the generator rotor to rotate in the magnetic field, and an electromotive force is generated in the wire, thereby generating electrical energy.
4. Electrical energy is output through the output terminal and supplied to the load.
