Transportation and power generation have historically relied upon Internal Combustion Engines (ICEs). However, because of environmental impact inefficiency, considerable research has been devoted to improving their performance. Alternative fuels are necessary concerns the depletion non-renewable fuel stocks. Biodiesel potential reduce emissions improve sustainability when compared diesel fuel. Several researchers examined using nanofluids increase biodiesel performance in internal combustion engines. Due thermal physical properties, nanoparticles a host fluid engine efficiency. This comprehensive review examines three key areas for ICE efficiency: as an alternative fuel, application nanofluids, artificial intelligence (AI)/machine learning (ML) integration. The integration AI/ML nanoparticle-infused offers exciting possibilities optimizing production processes, enhancing article first discusses, benefits concerning environment various difficulties associated with its usage. then explores effects characteristics IC engines, aiming know on After that, this discusses utilization techniques biodiesel-nanofluid process. sheds light ongoing efforts make technology more environmentally friendly energy-efficient by examining current emerging patterns these fields. Finally, presents challenges future perspectives field, paving way improvement.

As the world addresses increasing demand for sustainable energy solutions, biodiesel has surfaced as a viable alternative to conventional fossil fuels. The expansion of feedstock plantations, particularly palm oil in tropical regions, can lead deforestation, loss biodiversity, and significant carbon emissions from destruction carbon-rich ecosystems. That is why this article focuses on production waste sources order maintain balance ecosystem. This review paper discusses global landscape need renewable environmentally friendly alternatives. It explores various depth that are investigated production, comprising cooking oil, animal fats, algae, other organic residues. Each analyzed its viability, challenges, economic feasibility production. A critical assessment different methods, such transesterification, pyrolysis, thermochemical conversion, anaerobic digestion, thermal cracking, hydro-treating enzymatic processes, presented, highlighting key factors influencing their efficiency scalability. Recent developments enhance waste-derived production's sustainability viability meet UN Sustainable Development Goals also highlighted. Furthermore, environmental impact biodiesel, including greenhouse gas land use, discussed provide holistic understanding ecological footprint. significantly increase brake engine along with substantial decrease like CO HC. However, NOx CO2 increased application sources. be reduced by exhaust recirculation selective catalytic reduction techniques. regulatory frameworks standards governing sources, emphasizing harmonized policies encourage widespread adoption. concludes outlining future research directions potential breakthroughs could further effectiveness, sustainability, scalability Waste Cooking Oil (WCO) fats currently most economically feasible options due low cost established collection processing infrastructure. Algae present high but require technological advancements reductions become viable. aims assist researchers, policymakers, industry stakeholders advancing utilization materials promoting more landscape.
