摘　　要：介绍沼气成份、性质、燃烧特性和沼气净化,分析在柴油机上燃用沼气的影响因素,及采用的技术措施。通过对改装的沼气柴油双燃料发动机性能和原机对比试验研究,证明在原机压缩比不变,增大进气量,控制引燃量及增大供油提前角等技术措施下,柴油机能取得明显节油效果,其动力性接近原机指标。The elements, property, burning features and depuration of biogas were briefly introduced, and the influencing factors of burning biogas and technology adopted in diesel engines were analyzed. Through the contrast of the performance between the reequipped biogas-diesel dual fuel engine and the original one, it was concluded that under the same compression ratio, greater intake airflow, controlling the fuel induced and increasing the fuel feeding advance angular etc, the diesel engine can achieve the obvious oil-saved effect, and the indexes of the biogas are near to those of the original engine.
