对正丁醇（正丁醇）与常规柴油的掺混效果进行了试验研究，掺混量分别为8%和16%（体积分数）。正丁醇，性能和废气排放的一个完全仪表化的，六缸，水冷，涡轮增压和后冷，重型，直喷，梅赛德斯-奔驰发动机，安装在作者的实验室，这是用来驱动的小型公共汽车柴油发动机的雅典城市交通组织车队。使用上述每种燃料混合物进行测试，发动机以两种速度和三种负荷工作。测量油耗、排气烟度和排气调节气体排放，如氮氧化物、一氧化碳和总未燃碳氢化合物。确定并比较了两种丁醇/柴油燃料混合物与发动机基线操作（即，当使用纯柴油燃料时）的测量性能和废气排放的差异。结果表明，该燃料可以由生物质（生物丁醇）生产，是一种很有前途的柴油发动机生物燃料。不同的物理和化学性质的正丁醇对那些柴油燃料，样品气缸压力和放热速率图的帮助下，被用来解释所观察到的发动机的行为。(C)2010爱思唯尔有限公司版权所有。
An experimental investigation is conducted to evaluate the effects of using blends of n-butanol (normal butanol) with conventional diesel fuel, with 8% and 16% (by vol.) n-butanol, on the performance and exhaust emissions of a fully instrumented, six-cylinder, water-cooled, turbocharged and after-cooled, heavy duty, direct injection (DI), Mercedes-Benz engine, installed at the authors' laboratory, which is used to power the mini-bus diesel engines of the Athens Urban Transport Organization sub-fleet. The tests are conducted using each of the above fuel blends, with the engine working at two speeds and three loads. Fuel consumption, exhaust smokiness and exhaust regulated gas emissions such as nitrogen oxides, carbon monoxide and total unburned hydrocarbons are measured. The differences in the measured performance and exhaust emissions of the two butanol/diesel fuel blends from the baseline operation of the engine, i.e. when working with neat diesel fuel, are determined and compared. It is revealed that this fuel, which can be produced from biomass (bio-butanol), is a very promising bio-fuel for diesel engines. The differing physical and chemical properties of n-butanol against those for the diesel fuel, aided by sample cylinder pressure and heat release rate diagrams, are used to interpret the observed engine behavior.
