【摘要】 以93#无铅汽油为基础油,按照体积分数20%和30%配制出相应的丁醇—汽油混合燃料,分析研究了电喷汽油机燃用不同掺混比丁醇—汽油混合燃料时的动力性和经济性。研究结果表明,在不改变汽油机任何参数的情况下,与原汽油机相比,20%体积掺混率的丁醇—汽油混合燃料性能相差不大,在低转速性能还稍有提高。而掺混30%丁醇的混合燃料动力性仅有4%下降。在对发动机进行点火提前修正后,动力性可以基本恢复。更多还原

【Abstract】 The effects of the butanol-gasoline blended fuels with various blended ratios on the engine performance and economy are investigated experimentally.The fuels are mixed based on volume ratio(20%and 30%volume,respectively).The results show that the 20%blended fuels has little loss on the power compared the original 93# gasoline fuel without any modification of the engine.The performance at low speed is even better.At high mix ration 30%,the maximum torque of the blended fuel decreases about 4%.But when the ignition angle of the engine is adjusted,the power can be recovered.更多还原
