摘要：为了合理利用丰富的沼气资源，将5 kW汽油发电机改装成可以燃用沼气的燃气发电机，并设计了水容式阻火器、稳压减压器等安全设施；对改装后的燃气机采取了提高压缩比、增大点火提前角、采用高能点火等优化改进措施，并对发电机燃用汽油和沼气进行了性能对比试验。试验结果表明：该系统能够安全可靠地工作，机组燃沼气时排放比燃汽油时得到明显改善，有效燃料消耗降低，经济性更好。

Abstract: In order to develop and utilize biogas, a 5 kW gasoline generator was converted into biogas generator. A firerestrain device and pressure reducer were designed to ensure safety. The measures such as increasing the compression ratio, enlarging spark advance and using highenergy ignition were taken to improve the performance of the engine running on gas. Experiment was done to compare the performances of the generator runs on gasoline or biogas. The result shows that the emission and economy of the generator are better when it runs on biogas than that on gasoline.
Key words: biogas; internal combustion engine; generator
