Abstract


In the pursuit of enhanced automotive performance without compromising the environment, researchers and manufacturers explore alternative fuels. Ethanol, as a substitute for gasoline in spark ignition engines, have received significant attention. This study utilized Ricardo wave software to simulate a 4-cylinder spark ignition engine, maintaining a constant compression ratio of 10. Various fuel blends (ranging from E0 to E100) were analysed at different speeds (1500, 3000, 4500, and 6000rpm), evaluating parameters like brake power, fuel consumption, thermal efficiency, and emissions (CO, NOx, UHC). The investigation highlighted the impact of different ethanol-gasoline blends on engine performance and emissions. Using Design Expert software for parameter optimization, the study revealed that E85 emerged as the optimal blend across all speeds considered. E85 showcased superior performance among the blends, suggesting its viability as an optimal fuel choice for spark ignition engines. These findings hold potential implications for automotive design and policy, indicating a promising pathway towards improved performance with reduced environmental impact
