一、工作原理與燃料適應性

1、 Working principle and fuel adaptability

工作原理：沼氣發電機組通過壓縮“空氣沼氣”混合物，利用火花塞點燃，推動活塞往復運動產生動力，進而驅動發電機發電。

Working principle: The biogas generator unit compresses the "air biogas" mixture, ignites it with a spark plug, and drives the piston to reciprocate to generate power, thereby driving the generator to generate electricity.

燃料適應性：沼氣發電機組可以全部使用沼氣作為燃料（單燃料沼氣發電機組），也可以部分使用沼氣并輔以柴油等液體燃料（雙燃料沼氣-柴油發電機組）。這種靈活性使得發電機組能夠適應沼氣產量和甲烷濃度的變化。

Fuel adaptability: Biogas generators can use all biogas as fuel (single fuel biogas generators), or partially use biogas supplemented with liquid fuels such as diesel (dual fuel biogas diesel generators). This flexibility enables the generator set to adapt to changes in biogas production and methane concentration.
