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.

“…Among the noted efforts to achieve improved atomization is the use of fuel additive . Javed et al demonstrated that emissions from a direct injection diesel engine can be decreased by adding metallic fuel‐borne additives (zinc oxide). However, the use of additive for atomization increased hydrocarbon (HC) emission with larger particle size and also increased smoke opacity as compared with conventional method.…”

Fuel atomization in gas turbines: A review of novel technology

et al. 2019

Summary The atomization of fuel is crucial in the combustion and emission of a gas turbine, and the fuel atomization is continuous without any cycles or strokes. However, to achieve a desired amount of combustion during this continuous process, fuel must be added and mixed with the high‐pressure air exiting the compressor in proper proportions. To make the engine as small and lightweight as possible is a constraint and requires the fuel injection, mixing, and combustion to occur within the smallest volume possible. In most cases, this is inefficient and less practicable. A major drawback is the requirement of high injection pressure with relatively small increase in flow rate. In recent years, research was conducted to improve fuel atomization in a gas turbine by using different novel approaches that were simpler, more adaptable, and efficient to enhance the atomization. However, most of these studies were in isolation without any comprehensive literature on recent trends. Therefore, this review attempts to give an insight on recent development of fuel atomization in a gas turbine. Particular emphasis was given to air‐, plasma‐, ultrasound‐, and supercritical fluid–assisted atomization techniques.

Fuels dispersed with engineered nanoparticle additives, or nanofuels, are desirable for the vastly different combustion properties such as combustion rate and ignition delay they exhibit compared to base fuels. The stability of such nanofuels over time and under different particle loadings is a very important parameter to consider before they can be put into practical use. Many techniques exist today to analyze suspension stability, which have been developed to analyze water-based nanofluids. Sometimes these techniques can be expensive, and/or require specialized equipment, and/or require a method that is invasive and disturbs the suspension. Present research uses a non-contact, non-invasive, low-cost experimental setup to analyze suspension stability over long periods of time. Nanofuels made from carbon-based nanomaterials (acetylene black, multiwalled carbon nanotubes) and metal oxide nanomaterials (copper oxide, aluminum oxide) with hydrocarbon fuels (canola biodiesel, petrodiesel) have been prepared and their settling rates have been analyzed over the period of three days. It is found that metal oxides go through several metastable states as they settle. The effect of initial concentration and liquid column height is shown. It is hoped that present research showcases the positive traits of the presented technique and will spark further interest in nanofuel stability. Number of words: 198
