摘　　要：高密度液体碳氢燃料挂式四氢双环戊二烯(exo-THDCPD)密度大、热值高,具有作为应急增程燃料提升车辆装备机动距离的潜能。为考察柴油发动机燃用exo-THDCPD的动力性、增程性和排放性,将exo-THDCPD以不同体积分数(0、20%、40%、60%)与0号柴油掺混调制成高密度复合燃料,在测试分析理化性能指标的基础上,进行发动机模拟台架试验,研究高密度复合燃料对柴油机性能的影响。结果表明:当exo-THDCPD添加体积分数不超过40%时,高密度复合燃料理化性能满足柴油机(应急代用)燃料技术要求;当exo-THDCPD添加体积分数分别为20%、40%时,与0号柴油相比,柴油发动机功率平均增加3.21%、6.72%,油耗率平均降低1.72%、3.78%,HC排放平均增加23.36%、69.98%,CO排放平均增加48.28%、76.67%,NOx排放平均增加3.61%、9.38%。Exo-tetrahydrodicyclopentadiene(exo-THDCPD),a liquid hydrocarbon fuel with high energy density and calorific value,has the potential to improve the endurance performance of vehicle equipment as an alternative fuel for emergency use.To explore the performance of exo-THDCPD in terms of power,range extension and emission when used by diesel engine,a high density composite fuel was prepared through blending different volume fractions of exo-THDCPD(0,20%,40% and 60%) with No.0 diesel.Then an engine simulation bench test was conducted based on the testing and analysis of relevant physicochemical performance indicators,so as to investigate the effect of the high density composite fuel on the performance of diesel engine.Experimental results show that when the blending volume fraction of exo-THDCPD is less than 40%,the physicochemical performance of the high density composite fuel can well satisfy the technical requirements from alternative fuel for emergency use;when compared with No.0 diesel alone,the addition volume fraction of 20% and 40% exo-THDCPD in No.0 diesel can,achieve an average increase of 3.21% and 6.72% in engine power,23.36% and 69.98% in HC emission,48.28% and 76.67% in CO emission,3.61% and 9.38% in NOxemission,as well as an average decrease of 1.72% and 3.78% in fuel consumption rate,respectively.
