火花点火沼气发动机的快速燃烧研究与产品开发

沼气燃烧速度慢是造成沼气发动机燃烧持续期长，燃烧效率低，后燃严重，排温高，可靠性与经济性差的根本原因。该文利用快压机对沼气发动机的燃烧过程进行了模拟，提出了改善火花点火沼气发动机性能的快速燃烧方法，设计出了包括燃烧室在内的快速燃烧系统，并将其用于6160沼气发动机发电机组的开发，大大提高了沼气在发动机中的燃烧速度，改善了该沼气发动机可靠性与经济性。

FAST BURNING COMBUSTION STUDY AND PRODUCT DEVELOPMENT FOR BIOGAS ENGINE

Low burning rate of biogas is the main problem in spark ignited biogas engine, such as serious back burning and high exhaust temperature . A rapid Compression-Expansion Machine was used to simulate the Combustion of biogas in engines. A fast burning system was used in the development of 6160 S.I. biogas generator. Experimental research shows that the combustion system can quicken the combustion of biogas air mixtures and improve the combustion process of biogas engines. The new system has advantages of improving reliability and efficiency of biogas engine.
