试验研究了汽油中添加甲醇和丁醇对制动比油耗(b.s.f.c.)、排气温度和热效率的影响。一台九头蛇单缸火花点火燃油喷射发动机在很大的燃料/空气当量比(ϕ=0⋅8至1⋅3)范围内用于30%体积的酒精-汽油混合物。这项工作的目的是研究发动机使用甲醇和丁醇汽油混合燃料时的性能。性能测量表明，b.s.f.c有所增加。当使用酒精-汽油混合物时，以及b.s.f.c.丁醇-汽油混合物比甲醇-汽油混合物要少。试验结果表明，燃用乙醇-汽油混合燃料后，发动机的热效率降低。结果表明，在ϕ=1⋅0时，掺入30%丁醇的发动机热效率比纯汽油降低约4.5%。排气温度测量表明，与乙醇汽油混合燃料相比，使用汽油时的温度有所升高，当使用汽油和酒精汽油混合燃料时，排气温度在ϕ≈1⋅1达到最大值。©1997 John Wiley&Sons，Ltd.
The effect of methanol and butanol addition to gasoline on brake specific fuel consumption (b.s.f.c.), exhaust gas temperature, and thermal efficiency has been experimentally investigated. A Hydra single cylinder, spark ignition, fuel injection engine was used over a wide range of fuel/air equivalence ratio (ϕ=0⋅8 to 1⋅3) for 30% volume alcohol–gasoline blends. The goal of this work is to study the engine performance when methanol and butanol–gasoline blends are used. The performance measurements show that there is an increase in b.s.f.c. when using alcohol–gasoline blends, and b.s.f.c. of a butanol–gasoline blend is less than for a methanol–gasoline blend. The experimental results show that the engine thermal efficiency was decreased when fueled with alcohol–gasoline blends. It was found that there was about a 4.5% reduction in engine thermal efficiency at ϕ=1⋅0 when 30% butanol was blended with gasoline compared to pure gasoline. The exhaust gas temperature measurements show that there is an increase in temperature in the case of using gasoline as compared to alcohol–gasoline blends, and that the temperature reaches a maximum at ϕ≈1⋅1 when using gasoline and alcohol–gasoline blends. © 1997 by John Wiley & Sons, Ltd.
