Abstract

Purpose This study aims at improving combustion process to reduce emissions. Emissions such as carbon monoxide, particulate matter and unburnt hydrocarbons are a result of incomplete combustion. These emissions have useful energy but cannot be reclaimed. Hence, to enhance combustion, effect of biofuel blending on diesel combustion was investigated. Design/methodology/approach Essential oils have been found easier for blending with diesel because of simple molecular structure compared to vegetable oils. Lavender oil is an essential oil which has not yet been studied by blending with diesel. The major constituents of lavender oil are linalyl acetate (cetane number improver) and linalool (nitrogen oxides reduction). A single-cylinder, four-stroke diesel engine was run by blending diesel with lavender oil (Lavandula angustifolia oil [LAO]) in varying proportions, 5%, 10% and 15% by volume. Findings Higher heat release rate (HRR) was observed using lavender oil blends compared to pure diesel. Compared to diesel, an increase in brake-specific fuel consumption using blends was observed. LAO15 has the lowest CO emissions at all loading conditions, 29.3% less at 100% load compared to diesel. LAO5 and LAO15 have 6.9% less HC emissions at 100% load condition compared to diesel. LAO15 has only 1.3% higher NOx emissions compared to diesel at 100% load condition. LAO5 has the lowest smoke content at all loading conditions. Research limitations/implications Lavender oil was used directly without any processing. Tested on single-cylinder engine. Originality/value To the best of the author’s knowledge, currently, there is no published work on lavender oil–diesel combination. Lavender oil can provide a simple renewable solution for diesel additives with potential up to 15% blending.

薰衣草混合油对柴油燃烧和排放特性的改善

目的本研究旨在改善燃烧过程以减少排放。一氧化碳、颗粒物和未燃烧碳氢化合物等排放物是不完全燃烧的结果。这些排放物具有有用的能量，但无法回收。因此，为了提高柴油的燃烧性能，研究了掺混生物燃料对柴油燃烧的影响。设计/方法/方法与植物油相比，由于分子结构简单，精油更容易与柴油混合。薰衣草油是一种尚未与柴油混合的精油。薰衣草油的主要成分是芳樟醇乙酸酯（十六烷值改进剂）和芳樟醇（减少氮氧化物）。通过将柴油与薰衣草油（Lavandula angustifolia oil[LAO]）以不同的比例（按体积计5%、10%和15%）混合来运行单缸四冲程柴油发动机。发现与纯柴油相比，使用薰衣草油混合物观察到更高的放热率（HRR）。与柴油相比，使用混合燃料的制动器比油耗有所增加。LAO15在所有负载条件下的CO排放量最低，与柴油相比，在100%负载下减少29.3%。与柴油相比，LAO5和LAO15在100%负载条件下的HC排放量减少了6.9%。与100%负载条件下的柴油相比，LAO15的NOx排放量仅高1.3%。LAO5在所有负载条件下具有最低的烟雾含量。研究局限性/含义薰衣草油是在没有任何加工的情况下直接使用的。在单缸发动机上测试。独创性/价值据作者所知，目前还没有关于薰衣草油-柴油组合的出版工作。薰衣草油可以为柴油添加剂提供一种简单的可再生解决方案，其混合比例可能高达15%。
