与使用化石燃料有关的排放问题导致了许多关于使用可再生燃料的研究工作。本研究的目的是评估含有巴豆油（CRO）， 1-丁醇（BU）和柴油（D2）的混合物对发动机性能，燃烧和排放特性的影响。研究样本为20% CRO - 80% D2, 15% CRO - 5% BU - 80% D2, 10% CRO - 10% BU - 80% D2，以D2为基线。密度、粘度、十六烷值、碳、氢、氧含量均按ASTM标准测定。试验使用了一台四缸涡轮增压直喷柴油发动机。与D2燃料相比，混合燃料的制动比能量消耗较高。在共混物中加入BU降低了制动热效率值。在更高的发动机负载下，含有bu的混合燃料显示出与D2相当的峰值气缸压力和热释放率。废气的二氧化碳和烟雾排放量在…
Emission problems associated with the use of fossil fuels have led to numerous research works on the use of renewable fuels. The aim of this study is to evaluate the effects of blends containing croton oil (CRO), 1-butanol (BU), and diesel (D2) on the engine performance, combustion, and emission characteristics. Samples investigated were 20% CRO−80% D2, 15% CRO−5% BU−80% D2, and 10% CRO−10% BU−80% D2, with D2 as the baseline. The density, viscosity, cetane number, and contents of carbon, hydrogen, and oxygen were measured by ASTM standards. A four-cylinder turbocharged direct-injection diesel engine was used for the tests. It was observed that the brake specific energy consumption of blends was found to be high compared to that of the D2 fuel. The addition of BU in the blend reduces the brake thermal efficiency values. BU-containing blends show peak cylinder pressures and heat release rates comparable to those of D2 on higher engine loads. Carbon dioxide and smoke emissions of the BU blends were lower in ...
