Special Issue Information

Dear Colleagues,

Focus: Renewable biofuels and green diesel are considered as an alternative to replace conventional fuels such as coal, oil, and natural gas. Thus, due to the several merits of biofuel for a cleaner and sustainable environment, it is expected to play a crucial role in the future fuel mix of various nations. The concept of biorefinery integrates the conversion of biomass, residues, and waste into renewable fuels, which has been an industrial activity all around the world. The development of economically viable conversion processes with fewer environmental impacts is a key area of the circular economy and green fuel technologies.

Scope: The various solutions to the global shortage of fossil carbon supply and the various technical, economic, social, policy, and political factors influencing renewable fuels will be discussed in this Special Issue. The final objective is to present a roadmap and pathways for the transition to a greener economy with the sustainable production and consumption of renewable fuel, in a broad set of countries/regions.

Purpose: This Special Issue will provide multidisciplinary, comprehensive, and state-of-the-art research on renewable biodiesel and green diesel which includes the selection of suitable biomass feedstocks into sustainable biofuels. Together, contributions will provide insights into research advances in biofuel research, potential feedstock, and engine applications. Authors are encouraged to supplement their results by considering the relevant issues of environmental, economic, sustainability, social, and policy aspects in stimulating green and renewable diesel production and utilization.

Environmentally friendly, renewable, and green fuels have many benefits over fossil fuels, particularly regarding energy efficiency, in addition to addressing environmental and socioeconomic problems. As a result, green fuels can be used in transportation and power generating applications. Furthermore, being green can ably address the emission-related issues of global warming. In view of the advantages of renewable fuels, two B20 fuel blends obtained from methyl esters of cashew nutshell (CHNOB), jackfruit seed (JACKFSNOB), and jamun seed oils (JAMSOB) were selected to evaluate the performance of a common rail direct injection (CRDI) engine. Compatibility of the nozzle geometry (NG) and combustion chamber shape (CCS) were optimized for increased engine performance. The optimized CCS matched with an increased number of injector nozzle holes in NG showed reasonably improved brake thermal efficiency (BTE), reduced emissions of smoke, HC, and CO, respectively, while NOx increased. Further combustion parameters, such as ignition delay (ID) and combustion duration (CD) reduced, while peak pressure (PP) and heat release rates (HRR) increased at the optimized injection parameters. The CRDI engine powered with JAMSOB B20 showed an increase in BTE of 4–5%, while a significant reduction in HC and CO emissions was obtained compared to JACKFSNOB B20 and CHNOB B20, with increased NOx.
