Abstract-The increasing concerns over environmental pollution, energy security, and the depletion of fossil fuel reserves have driven significant research and development in advanced alternate fuels for internal combustion (IC) engines. These fuels provide a sustainable and cleaner alternative to conventional gasoline and diesel while maintaining compatibility with existing technologies. Advanced fuels such as hydrogen, biodiesel, ethanol, methanol, compressed natural gas (CNG), liquefied petroleum gas (LPG), biogas, dimethyl ether (DME), ammonia, and synthetic e-fuels offer a range of environmental and performance benefits, including reduced greenhouse gas emissions, improved engine efficiency, and lower particulate matter. However, their adoption faces challenges like production costs, fuel storage and distribution, infrastructure limitations, and the need for engine modifications. Innovations such as dual-fuel engines, advanced combustion technologies like HCCI (Homogeneous Charge Compression Ignition) and PCCI (Premixed Charge Compression Ignition), and fuel additives are critical in addressing these barriers. This paper explores the characteristics, advantages, challenges, and applications of advanced alternate fuels for IC engines, emphasizing their potential to decarbonize transportation and ensure a sustainable energy future. By integrating these fuels with evolving engine technologies, the automotive industry can significantly contribute to reducing environmental impact and achieving global sustainability targets.
