The increasing concerns over environmental degradation and depleting fossil fuel reserves have led to intensified research efforts in alternative and sustainable energy sources. One promising avenue is the utilization of biofuels derived from biocrude, a renewable and environmentally friendly feedstock. This review paper investigates the engine performance and emission characteristics of a biofuel derived from biocrude through the pyrolysis method. The research focuses on assessing the feasibility and potential of utilizing biocrude-based biofuels as a sustainable alternative in internal combustion engines. Parameters such as brake thermal efficiency, Brake specific fuel consumption and emissions characteristics such as nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons (HC), were compared with traditional fossil fuels. The findings from different blends of biofuel i.e. CNSL B20, F20,C10 suggest promising results in terms of engine performance, demonstrating comparable efficiencies and highlighting the potential for reduced emissions with biocrude-derived biofuels. The review begins by outlining the various methods of biocrude production, highlighting their advantages and limitations. Subsequently, it delves into the intricate relationship between biocrude composition and biofuel properties, elucidating how variations in feedstock and processing techniques influence fuel quality. The review also highlights recent advancements in engine design and fuel injection systems tailored to biocrude-derived biofuels, aiming to maximize compatibility and performance. The findings presented herein contribute to the ongoing dialogue on sustainable energy solutions and offer valuable insights for researchers, engineers, and policymakers navigating the dynamic landscape of biofuel development and implementation.
