摘　　要：在ZX195节能型柴油机上采用排气管汽化无水乙醇、进气管预混的方式,进行了掺烧无水乙醇的正交试验,随后研究了柴油机在不同工况下,针对能耗率和烟度不同控制对象,优化了无水乙醇掺烧比例,试验的研究结果显示,当柴油机以最低能耗率为控制对象时,无水乙醇最佳掺烧比例范围为19%~29%;当柴油机以烟度为控制对象,且增加不超原机的能耗率约束时,多数工况下无水乙醇掺烧比例在35%左右。The orthogonal tests were conducted on the ZX195 energy-saving diesel by vaporizing anhydrous ethanol on exhaust pipe and premixing it on intake pipe,the optimizing proportion of intake anhydrous ethanol was calculcated to different needs for energy consumption and smoke under different working conditions.The results showed that the optimizing proportion of intake anhydrous ethanol was 19%~29%for attaining the minimum energy consumption under different working conditions;the proportion around 35%could lead to the reduction of the somke,under no more than the energy consumption of the original machine.
