Climate change necessitates urgent action to decarbonize the transport sector. Sustainable vehicles represent crucial alternatives traditional combustion engines. This study comprehensively compares four prominent sustainable vehicle technologies: biofuel-powered (BPVs), fuel cell (FCVs), electric (EVs), and solar vehicles. We examine each technology’s history, development, classification, key components, operational principles. Furthermore, we assess their sustainability through technical factors, environmental impacts, cost considerations, policy dimensions. Moreover, discussion section addresses challenges opportunities associated with technology assesses social impact, including public perception adoption. Each offers promise for transportation but faces unique challenges. Policymakers, industry stakeholders, researchers must collaborate address these accelerate transition toward a decarbonized future. Potential future research areas are identified guide advancements in technologies.

Depending on the heat content and compression ignition (CI) engine combustion, biodiesel is a viable substitute fuel. Biodiesel an oxygenated, safe, sulfur-free, biodegradable, renewable It may be utilized in CI engines any combination with diesel fuel without requiring to significantly modified. Many research studies have been made several biodiesels as substitutes, including Pongamia pinnata, Jatropha curcas, Mangifera indica, Madhuca longifolia. The topic of current review potential fuels outperform terms performance, emission characteristics. In present study, are fueled from Man. Mad. longifolia, pongamia seed oil. Adopting low rejection (LHR) mode adding antioxidant agent addition blends resolve issue these biodiesels' poorer performance increased NO emission. Both additions provide positive approaches both

A mixture of diesel, biodiesel (from algae), and butanol was mixed with nano-titanium dioxide at 50 100 parts per million in this study under post-injection (PI) strategy two rates (10 % 20 %) exhaust gas recirculation (EGR). In the literature, few studies have investigated how PI strategies effect on engine emissions combustion performance from B16M20 by (16 %), microalgae (15 diesel variable EGR rates. To gain a better understanding effects engines running mixture, conducted. The final fuel type test used treated ppm nano-TiO2. Fuel specific consumption (BSFC) increased 3 for both when used, but reversed trend. Nanoparticles added to blend significantly contributing decreased BSFC 6.47 %. nano-TiO2 10 EGR, along PI, can achieve same or enhance brake thermal efficiency (BTE) 4.53 than pure diesel. lowest NOX levels 26.48 were achieved nano-TO2 EGR. Because EGR's high heat capacity dilution effect, higher result soot levels. As strategy, emitted reduced 28.57 compared fuel.

Diesel engines are extensively employed in transportation, agriculture, and industry due to their high thermal efficiency fuel economy. However, the combustion of conventional diesel is accompanied by substantial emissions pollutants, including carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), dioxide (CO2), posing significant threats environmental quality. Biodiesel, as a renewable cleaner alternative fuel, can significantly reduce CO, HC, particulate matter (PM) its unique molecular structure. Nonetheless, lower calorific value poor cold-start performance limit application, while oxygen content may contribute increased NOx emissions. To address these limitations, researchers have proposed blending biodiesel with alcohol-based fuels such methanol, ethanol, or butanol create synergistic systems that optimize engine emission characteristics. This paper systematically reviews effects alcohol on characteristics blends engines. Studies indicate addition enhance improving atomization, extending ignition delay, increasing premixed efficiency. These enhancements result higher cylinder pressure, net heat release rate (HRR), brake (BTE), reducing brake-specific consumption (BSFC) some extent. Moreover, most studies report help smoke, but tend increase CO2 findings suggest certain cases, opposite results occur. The impact different types varies significantly, requiring comprehensive evaluation properties, latent heat, viscosity, content. Although appropriate demonstrates potential for optimizing emissions, excessive lead adverse effects, necessitating careful control ratio. Future research should consider mixing two more explore beyond capabilities single alcohols. Additionally, further focus compositions strategies varying operating conditions.
