摘　　要：各种农林废弃的生物质,经气化炉热解气化产生可燃生物制气,作为柴油为引燃燃料的双燃料发动机主要燃料,测量该发动机及柴油机在运转范围内的燃烧过程,并分析燃烧始点、最高燃烧压力及相位的变化规律。双燃料发动机与燃用纯柴油时的发动机相比,燃烧始点较迟,在低速大负荷时比柴油机气缸最高燃烧压力及最大压力升高率要大,在其余工况比柴油机要低。Biogas is made by a gasifier from, many kinds of agricultural and forestry residues. It is used as the main fuel of a dual fuel engine ignited by diesel fuel. The combustion characteristics of the biogas diesel dual-fuel engine and diesel engine are measured and analyzed. It is found that the cylinder pressure and maximum pressure rise of the dual fuel engine is greater than diesel engine when the engine speed is low and load is high. The dual-fuel engine cylinder pressure and maximum pressure rise is lower than diesel engine except when the engine speed is low and load is high.
