Abstract

This study investigates the impact of gasoline, ethanol, and fusel oil blends on engine performance and emissions under varying engine speeds (1000–3000 rpm) and throttle positions (10–40 %). The blends reduced brake power by 3.5–7.1 % and increased Brake-Specific Fuel Consumption by 6.1–16.8 % for ethanol and 4.6–15.9 % for fusel oil. Brake thermal efficiency also declined for both blends. However, emissions improved significantly, with NOx reductions of 17.3 % (ethanol) and 13.8 % (fusel oil), CO reductions of 13.1 % and 9.1 %, and HC reductions of 8.8 % and 6.16 %, respectively. The results highlight trade-offs between performance and emission benefits.
