【摘要】 针对汽油短缺和燃用汽油产生大量污染等问题,研究了以工业甲醇、C5+、C1～C5,助溶剂和腐蚀抑制剂组成的FBM(fuelbasedonmethanol)车用醇基燃料。对90#FBM车用醇基燃料进行了发动机台架性能试验:起动性能试验,怠速排放性能测试,速度特性试验和负荷特性试验。试验结果显示:与燃用90#汽油相比,发动机平均起动时间提前0.31s,表明了醇基燃料的冷机起动性能优于90#汽油;排污低于90#汽油;在100%油门开度下,转速在1000r min至2800r min之间,其最大功率比90#汽油下降2.47%,最大扭矩下降2.34%,最低燃料消耗率上升5.79%;1800r min负荷特性试验结果,平均燃料消耗率比90#汽油上升5.57%。更多还原

【Abstract】 According to the problems of petrol shortage and the pollution from the engine burning gasoline, FBM（fuel based on methanol）, which consists of main agent of 72%;25%C₅₊;2%C₁～C₅ and 1.0% MLN aiding solvent; and C₁₃₅corrosion inhibitor has been studied in this paper. The experiments of engine performances including the starting performance; the idling emission; the speed characteristic and the load characteristic have also been carried out for the engine fuelled by the FBM. The results indicate that compared with the performance of the engine fuelled by 90^# gasoline, the cool starting performance of the engine fuelled by 90^# FBM is superior for the average starting time decreasing by 0.31 second, and the emission from this engine is better slightly. When the engine runs at the speed between 1000r/min and 2800r/min with the accelerator opening cempletely, the engine power decreases by 2.47%; the engine maximum torque decrease by 2.34% and the minimun specific fuel consumption increases by 5.79%. At the speed of 1800r/min, the test of load characteristic indicates that the average specific fuel consumption inereases by 5.57%.更多还原
