Working Principle
Biogas goes through pretreatment (desulfurization, dehydration, pressure stabilization) to remove impurities and avoid equipment corrosion.
Purified biogas mixes with air in ratio, entering the engine cylinder.
The mixture is compressed, ignited by spark plug; high-temp/pressure gas pushes piston to drive crankshaft (thermal→mechanical energy).
Crankshaft rotates generator rotor to generate electricity (mechanical→electrical energy); control system adjusts biogas supply and speed for stable output.
