“…When the cost of the fuel is considered, it becomes clear that the use of conventional diesel fuel is significantly cost-effective when compared to the biofuel used in the experimentation. − Therefore, based on the conventional fuel cost, the scores were provided. The scores were sequentially allocated and are as follows: 1, −1, −1, −1, −1, −1, −1, and −1 for D100, AN100, AN80D20, AN70D30, and AN80D20 at 35 °C, AN80D20 at 40 °C, and AN80D20 at 45 °C.…”

The main aim of the study was to reduce carbon emissions in the atmosphere using a novel Andropogon narudus (AN) biofuel using higher air temperatures and reducing the consumption of conventional fossil fuel (diesel). The use of a heat exchange chamber within the air intake manifold is a popular method to reduce hydrocarbon (HC) and carbon monoxide (CO) emissions during cold starts. A premixed charged compression ignition engine in the dual-fuel mode was used in this study with raw diesel, raw AN oil, AN70+D30, AN80+D20, AN80+D20 (35 °C), AN80+D20 (40 °C), and AN80+D20 (45 °C). A chamber was designed and analyzed to measure the exit temperature and density change and to determine the reduction in volumetric efficiency of the engine, using Ansys Fluent software. A sustainability assessment study was performed to understand the feasibility of the fuel and the design using the Pugh Matrix. The fuel AN80+D20 with an air temperature of 45 °C was found to be superior to all other fuels in terms of brake thermal efficiency, reaching at 32.1%. D100 used the least amount of energy, whereas AN80+D20 used the most. Engine HC emission was at the lowest (45.01 ppm) for AN80+D20 fuel at 45 °C air input and reached the highest (50 ppm) for AN100 fuel. With an air temperature of 45 °C, CO emission was at its lowest for AN80+D20 gasoline (0.018%) and was at its highest for AN100 (0.072%). Nitrogen oxide emissions were the highest for AN80+D20 fuel with an air temperature of 45 °C, with an air concentration of 1254 ppm, whereas they were the lowest for AN100 (900 ppm). CO 2 values were reduced, with D100 showing the lowest levels and AN100 showing the highest. The smoke emission was minimum for AN80+D20 fuel at 45 °C, with a smoke number of 15 compared to 33 for D100 fuel. As per the Pugh Matrix assessment, AN80+D20 with 35 °C air temperature had higher scores compared to all of the other fuel mixtures.

The use of biofuels represents a promising means of achieving a sustainable future and offers considerable economic and environmental benefits. Since they are derived from organic sources, such as vegetable oils and animal fats, biofuels can mitigate the effects of greenhouse gas emissions, improve air quality, support local agriculture, create employment opportunities, and enhance energy security by reducing dependence on fossil fuels. However, introducing these alternative fuels to the aviation sector remains a significant challenge. Thus, it is vital to investigate the potential of sustainable aviation fuel (SAF) and discover how to overcome the technological obstacles to its integration into mainstream aviation to attain broader decarbonization objectives. This article seeks to contribute to a discussion about SAF by examining how it has evolved and its connections to related patents. This article is a comprehensive study of biofuel innovation, highlighting the complex relationships between academia, industry, and other stakeholders. It is hoped that the findings from this study will provide a clearer understanding of the catalysts involved in SAF innovation and provide valuable insights for policymakers, academics, and professionals in the field who are committed to shaping the trajectory of sustainable energy technologies in the future.
