Abstract | Butanol is widely investigated as a renewable biofuel additive in Compression-Ignition (CI) engines due to its ability to improve diesel fuel properties and reduce emission levels. Because Acetone-butanol-ethanol (ABE) and butanol-acetone (BA) are intermediate mixtures in bio-butanol production, they present cost benefits compared to butanol production by reducing energy consumption and the number of recovery processes. This paper evaluates and compares the effect of using butanol (B), BA and ABE additives with diesel (D) on macroscopic spray characteristics. Spray tests were carried out in a constant volume vessel (CVV) under different injection conditions. A high-speed camera was used to record spray images. Macroscopic spray characteristics including spray penetration, spray cone angle and spray volume were measured. The experimental results showed that spray penetration (S) was increased as a result of addition of all alcohols to diesel fuel as well as of increased injection pressure; spray cone angle () was slightly widened while it was slightly narrowed as a consequence of increase fuel injection. The spray volume of the alcohol-diesel blends showed a higher value compared to that of neat diesel due to high spray penetration length. Spray penetration and spray volume of BA-diesel blend were higher compared to ABE-diesel and Bdiesel blends. |
