“…Alcohols fuels can be derived from sugar cane wastes (e.g., molasses) and have already been adopted in a number of countries as an additive to diesel. − The longer-chain alcohol n -butanol has recently drawn particular attention as a potential alternative to diesel fuel. − Alcohols with a longer carbon chain length have merit over shorter chain alcohols due to their higher calorific value, lower cetane number, larger air–fuel ratio range, improved miscibility with diesel, and superior cold flow properties. − n -Butanol, commonly known as “butanol”, is a straight chain alcohol containing 4-carbon atoms. It can be derived from biobased resources. , Several studies in the literature have found lower PM emissions for butanol-diesel and butanol-biodiesel blended fuel compared to neat diesel fuel. ,,− The improved fuel atomization and fuel–air mixing for n -butanol blended fuels lead to lower PM 2.5 concentration and PM number emissions …”

In order to comply with strict emission standards, a reduction in diesel particle matter emissions can be addressed by minimizing particle formation and by optimizing particle oxidation in the combustion chamber and in the exhaust and diesel particulate filter systems. The characterization of soot morphology and nanostructure is necessary to understand the soot formation and oxidation processes. Furthermore, understanding these characteristics is important because they affect the aerodynamic behavior of diesel particulate matter in the exhaust system, diesel particulate filter systems, and the environment. This study aims to investigate the influence of fuel oxygen content and engine operating modes on the morphology and nanostructure of soot particles. The oxygen content in the fuel was varied from 0% to 4.32% and 6.48% by using diesel and 20 and 30% butanol blends (by volume) with diesel. As the oxygen content increased, corresponding nanostructure characteristics fringe length and separation distance increased and fringe tortuosity decreased. Changes to the nanostructure properties will have an influence on the operation of diesel particle filters, particularly during the regeneration processes. However, other characteristics such as the influence of these fuels on particle mass and number emissions, performance parameters, and gaseous emissions will also have a significant influence on implementing these fuels in modern diesel vehicles.

Summary The dependence on petroleum has been escalating owing to the proliferation of energy demands and population. Environmental degradation and depletion of petroleum resources are motivated to search the clean energy fuels for diesel engines. Recent studies have been advocated biodiesel as a strong contender to diesel fuel for diesel engines. Despite the significant development in the biodiesel field, there are still issues related to the usage of biodiesel in diesel engines. To overcome these issues, n‐butanol is identified as a biofuel additive that can improve the properties of biodiesel and its blends. The objective of this review is to compare the effect of the butanol–biodiesel (Bu/B), butanol‐biodiesel‐diesel (Bu/B/D), and biodiesel‐diesel (B/D) blends on the performance, combustion, and emission characteristics of diesel engines. Performance characteristics for Bu/B/D blends were observed remarkable than Bu/B and B/D blends, however, slightly inferior to diesel fuel. Combustion parameters of Bu/B/D blends were analogous to B/D blends however superior to Bu/B. Emission characteristics were reduced to a great extent with Bu/B/D blends as compared to all other sample fuels. This article also analyses the overview of biobutanol production from lignocellulosic biomass by acetone‐butanol‐ethanol fermentation process. Finally, this study reports that butanol has the potential, which can help to sustain engine performance and mitigate emissions. Among all the Bu/B, Bu/B/D, and B/D blends, Bu/B/D blends provide better fuel quality and significant results from the diesel engine characteristics; however, up to 20% blending of butanol with B/D blends showed better results after that engine performance decreased.
