Abstract
AbstractThe introduction of emulsion fuels has attenuated the problem of emissions from diesel engines without any engine modification. Emulsion fuel provides improved combustion characteristics with comparable or slightly reduced engine performance. This study presents a critical review of the research conducted on emulsion fuel technology concentrating on emulsion formulation techniques, emulsion stability, and its implications on engine performance and engine emissions. It is observed from the literature that the mixing process affects the particle size of the emulsion, which in turn influences emulsion stability. The presence of a polar solvent induces secondary atomization, which stimulates the micro-explosion phenomenon, increasing combustion efficiency. However, the decrease in combustion temperature with the addition of polar solvent limits its concentration. In addition, the accumulation of polar solvent reduces emissions, but it can have an adverse effect on the combustion phenomenon. The exergy analysis of emulsion fuel use in engines reveals opportunities for enhanced exergy efficiency. Appropriate selection of fuel components tends to improve exergetic efficiency. Future research on emulsion fuel can focus on improved fuel formulation technologies, engine endurance studies, and the long-term effect of the micro explosion phenomenon.Keywords: Microemulsionsurfactantstabilitybiofuelemission Disclosure statementThe authors report there are no competing interests to declare.

期刊介绍：
Current energy systems need a vast transformation to meet the key demands of the 21st century: reduced environmental impact, economic viability and efficiency. An essential part of this energy revolution is bioenergy.
The movement towards widespread implementation of first generation biofuels is still in its infancy, requiring continued evaluation and improvement to be fully realised. Problems with current bioenergy strategies, for example competition over land use for food crops, do not yet have satisfactory solutions. The second generation of biofuels, based around cellulosic ethanol, are now in development and are opening up new possibilities for future energy generation. Recent advances in genetics have pioneered research into designer fuels and sources such as algae have been revealed as untapped bioenergy resources.
As global energy requirements change and grow, it is crucial that all aspects of the bioenergy production process are streamlined and improved, from the design of more efficient biorefineries to research into biohydrogen as an energy carrier. Current energy infrastructures need to be adapted and changed to fulfil the promises of biomass for power generation.
Biofuels provides a forum for all stakeholders in the bioenergy sector, featuring review articles, original research, commentaries, news, research and development spotlights, interviews with key opinion leaders and much more, with a view to establishing an international community of bioenergy communication.
As biofuel research continues at an unprecedented rate, the development of new feedstocks and improvements in bioenergy production processes provide the key to the transformation of biomass into a global energy resource. With the twin threats of climate change and depleted fossil fuel reserves looming, it is vitally important that research communities are mobilized to fully realize the potential of bioenergy.
