Gasoline Generator Set is usually composed of stator, rotor, end cover and bearing. The portable gasoline generator is a machine that converts chemical energy into mechanical energy. Its conversion process is actually the process of working cycle. In simple terms, it burns the fuel in the cylinder to generate kinetic energy to drive the reciprocating movement of the piston in the engine cylinder. Drives the connecting rod connected to the piston and the crank connected to the connecting rod to make a reciprocating circular motion around the center of the crankshaft to output power.
