木质素准液体燃料在柴油机上的试验研究
|
摘要
木质素准液体燃料是一种很有代用前景的燃料,是一种介于固体和液体之间的准液体燃料。本文中将木质素与纯柴油以及适量的乳化剂混合后通过均质机均质,得到木质素准液体燃料。而后在S195单缸柴油机上对两种不同燃料进行发动机台架试验,得出柴油机燃用木质素准液体燃料和纯柴油的负荷特性和排放特性曲线,同时对木质素准液体燃料和纯柴油的油耗率进行了对比。研究结果表明:木质素能够替代柴油做功;使用木质素准液体燃料作为代用燃料的输出功率与使用纯柴油几乎相同,且在1600 r/min时较纯柴油有明显的节油效果,所排出的二氧化碳(CO_2)、一氧化碳(CO)、碳氢化合物(HC)含量均降低。
Lignin quasi-liquid fuel is a promising alternative fuel,which is a kind of fuel energy between solid and liquid. Lignin was mixed with diesel oil and appropriate emulsifier and homogenized by homogenizer to obtain lignin quasiliquid fuel. Two different fuels were tested on S195 single cylinder diesel engine,and the load characteristic and emission characteristic curves of lignin quasi-liquid fuel and pure diesel fuel were obtained. The fuel consumption ratio of lignin quasi-liquid fuel and pure diesel fuel was compared. The results showed that lignin can substitute for diesel for power,and the lignin quasi-liquid fuel had almost the same power output as the alternative fuel,and had more obvious oil saving effect than pure diesel at 1600 r/min. Emissions of carbon dioxide(CO_2),carbon monoxide(CO),and hydrocarbons(CnHm) were reduced.
