Description

The working principle of fuel generators is similar to that of internal combustion engines. It mainly includes four parts: fuel supply system, combustion system, cooling system and power generation system. The fuel supply system is responsible for extracting fuel from the fuel tank into the engine. After filtering and atomization, it enters the combustion chamber to prepare for combustion; the combustion system is responsible for igniting the mixed gas in the combustion chamber, generating high-temperature and high-pressure gas to drive the piston to move and drive the crankshaft to rotate; the cooling system maintains the normal operating temperature of the generator through coolant circulation and heat dissipation; the power generation system uses the magnetic field interaction between the stator and rotor of the generator when the crankshaft rotates to generate electrical energy, which is output to electrical equipment after rectification and transformation.
