【摘要】 国内对火花点火式沼气发动机的研究甚少，生产的沼气发动机在运行中出现热负荷高、可靠性与经济性差的问题．本文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，并开发出具有风扇形燃烧室的新型快速燃烧系统。实验研究表明这种新型燃烧系统对改善火花点火式沼气发动机的可靠性与经济性具有明显的效果更多还原

【Abstract】 Research on ignited biogas engine is unsufficient in our country, which leads to serious problems of biogas engine such as high heat load, bad reliability and low efficiency. In this paper, by analysing the characteristics of biogas combustion, a method of fast burning is put forward to improve the performance of biogas enngine, and a new combustion system with Fan shaped combustion chamber is developed which is suitable to promote fast burning. Experimental research shows that this new combustion system has good effect on improving reliability and efficiency of biogas engine.更多还原
