在作者实验室的一台标准、全仪表化、四冲程、高速、直喷式Ricardo/Cussons 'Hydra'柴油机上进行了试验研究，以评价使用正丁醇（正丁醇）与常规柴油（正丁醇体积分数分别为8%、16%和24%）的混合燃料对性能和排放的影响。使用上述燃料混合物或纯柴油燃料中的每一种进行测试，发动机以2000 rpm的速度和三种不同的负荷工作。在每项测试中，都会测量油耗、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。三种丁醇柴油燃料混合物的测量性能和废气排放参数与柴油发动机的基线操作的差异，即，当使用纯柴油时，测定并比较。结果表明，这种燃料，它可以从生物质（生物丁醇）生产，形成一个具有挑战性和有前途的生物柴油发动机燃料。丁醇与柴油燃料的不同物理和化学性质用于帮助正确解释所观察到的发动机行为。(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%, 16% and 24% (by volume) n-butanol, on the performance and exhaust emissions of a standard, fully instrumented, four-stroke, high-speed, direct injection (DI), Ricardo/Cussons 'Hydra' diesel engine located at the authors' laboratory. The tests are conducted using each of the above fuel blends or neat diesel fuel, with the engine working at a speed of 2000 rpm and at three different loads. In each test, 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 emission parameters of the three butanol diesel fuel blends from the baseline operation of the diesel 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), forms a challenging and promising bio-fuel for diesel engines. The differing physical and chemical properties of butanol against those for the diesel fuel are used to aid the correct interpretation of the observed engine behavior. (C) 2010 Elsevier Ltd.
