摘　　要：从分析沼气燃烧特点出发，提出了改善火花点火式沼气发动机性能的快速燃烧方法，并开发出４种具有湍流型燃烧室的新型燃烧系统。实验研究表明：采用改进后的燃烧系统，可不同程度地改善火花点火式沼气发动机的性能，其中以半八卦形燃烧室的改善效果最为明显。In this paper, the characteristics of biogas combustion are analyzed. In order to improve the operation performance of biogas engine, a method of fast burning by using four new types of turbulent combustion chambers is put forward to increase mixture gas burning rate in combustion chamber. Experimental research shows that the new combustion systems have good effects on improving reliability and efficiency of biogas engine, especially by using the combustion chamber called Half Eight Diagram.
