摘要
分析了小桐子油的主要成分及理化性质。以ZH1115型直喷柴油机作为试验样机,用不同比例的油料作为燃料,测量了气缸压力及NOx、HC、CO和烟度等废气排放,分析其负荷特性。燃用小桐子油与燃用柴油时相比,发动机气缸压力和压力升高率,NOx、HC排放和排温均较低,烟度相当,只有CO排放略高。供油提前角提前时,燃用小桐子油的发动机气缸压力和压力升高率增大,NOx排放量增加,排气温度略有降低,CO排放量变化不大,HC排放量减少。
The main components and properties of physics and chemistry of Jatrapha curcasl oil were analyzed.The characteristics of performances,combustion and exhaust emissions of a ZH1115 diesel engine using different fuels were measured.It is found that when the engine using Jatrapha curcasl oil,the cylinder pressure,the pressure rise rate,emissions of NOx and HC,and the exhaust temperature were all lower than using diesel,the smoke was at equivalent level;however,the CO emissions was higher.The cylinder pressure and pressure rise rate and its NOx emission increased,but when the advance angle of fuel supply increased,the exhaust temperature decreased a little,the CO emission had little change,and HC emission reduced.
