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。
Based on the analysis of the characteristics of biogas combustion, a rapid combustion method to improve the performance of spark ignition biogas engine was proposed, and four new combustion systems with turbulent combustion chamber were developed. Experimental results show that the improved combustion system can improve the performance of spark-ignition biogas engine to varying degrees, of which the improvement effect of the semi-gossip-shaped combustion chamber is the most obvious.
