摘  要:
分析了生物制气的主要成份及热值。由柴油机改制的双燃料发动机 ,用生物制气作为主要燃料 ,柴油引燃 ,测量分析其负荷特性、气缸压力及 NOx、HC、CO和烟度等废气排放。双燃料发动机与柴油机相比 ,气缸压力和 NOx 排放量较低 ,烟度相当 ,HC、CO排放量和排温较高。供油提前角提前时 ,双燃料发动机气缸压力变大、NOx排放量增加、HC和 CO排放量减少、排温降低。

摘  要:
The main components, such as CO,H 2,CH 4,N 2,CO 2,etc, and heat values, which ranged between 4 575 to 5 506 kJ·m -3 , of biogas were analyzed. The characteristics of performances, combustion and exhaust emissions in a biogas and diesel dual fuel engine were measured. We found that the cylinder pressure and the NO x emission in/from a biogas and diesel dual fuel engine were both lower than those in/from a diesel engine and the smoke density was at the equivalent level; however, the HC and CO emissions and the exhaust temperature were higher. The cylinder pressure of a dual fuel engine and its NO x emission will increase, but the exhaust temperature, and the HC and CO emissions will decrease, when the advance angle of fuel supply is increased.
