摘　　要：利用超声波雾化系统,在一台涡流室式柴油机上进行了进气道供乙醇的试验研究。研究结果表明:超声波乙醇雾化系统,能够满足进气道供乙醇的性能要求,使柴油机燃用乙醇/柴油过程中,表现出稳定的工作性能;柴油机燃用乙醇/柴油的NOx、CO和碳烟排放比原机低,尤其满负荷时碳烟降幅较大;能量消耗率与原机基本相当,HC排放比原机高。Make use of ultrasonic atomization system, in a swirl chamber diesel engine on the inlet for the Study of alcohol. The results show that： ethanol ultrasonic atomization systems for ethanol to meet the performance requirements of the inlet, the engine fueled with ethanol / diesel fuel the process, show- ing stable performance; diesel engine fueled with ethanol / diesel Nox, CO and soot emissions are lower than the original machine, especially when the full load soot decrease greater; HC emissions are higher than the original machine, the energy consumption rate is roughly equal to the original machine.
