Modeling and Analysis of Engine Exhaust Manifold Performance with Numerous Alternative Fuels
Year: 2024
Type: article
Abstract: : The exhaust system plays a crucial role in the performance of internal combustion (IC) engines, significantly influencing fuel consumption, exhaust emissions, and operating temperature. Exhaust manifolds are particularly important for improving IC engine efficiency, with their design being critical for achieving optimal performance. Alcohols, due to their biobased origins, are promising renewable alternatives to gasoline. This study utilizes Computational Fluid Dynamics (CFD) analysis to examine the effects of velocity, temperature, and back pressure on the volumetric efficiency of exhaust manifolds. Two different manifold designs are analyzed, and the impact of various fuels including LPG, alcohol, and gasoline on their performance is assessed. By leveraging ANSYS and FUSION 360 software, the study identifies that gasoline yields lower pressure and velocity values, while a specific manifold design exhibits higher pressure values, highlighting its superior efficiency and overall performance
