【摘要】 介绍了热力发动机的一种优良代用燃料———沼气的特征,并且对沼气在发动机上的使用和发展情况进行了评述 沼气具有资源广泛、废物利用、价格便宜、燃烧完全、排放清洁等特点 沼气发动机分为双燃料式和全烧式两种,目前主要用作固定动力源 深入研究沼气的制取和沼气发动机的工作机理以及零部件和整机间的匹配是今后的主要工作更多还原

【Abstract】 A kind of clean alternative fuel——biogas is introduced.The application and development of the biogas engine are reviewed.Biogas has many merits such as waste use,wide distribution,fewer cost,complete combustion, and clean emission.There are two types of biogas engines: dedicated biogas engine and dual fuel engine.At present it is used as the fixed power source.It is necessary to study further the biogas gasification, the operation mechanism of the biogas engine and the matching of the assembly and the whole engine.更多还原
