Popis: This study aims to determine how acetylene induction in a diesel–corn oil biodiesel blend affects the engine's performance and combustion. Corn biodiesel has poor combustion qualities relative to ethanol. In this study, acetylene was inducted in varying quantities with a biodiesel mix and in combination with air. Test fuels with different shares of acetylene mass are referred to as B20, B20A05, B20A10, B20A15, B20A20, and B20A25, and all trials are carried out at 50% and 100% load. As the acetylene content increases, the brake specific fuel consumption of ternary fuel decreases within the ranges of 7.2–12.9% on average at 100% load. Ternary blends, however, showed lower mass consumption of fuel than B20 and neat diesel fuel. Brake thermal efficiency value of 23.9% was observed for a B20A25 blend. Also, at 100% load, the diesel–corn biodiesel mix had a higher exhaust gas temperature than diesel. Carbon monoxide (CO), hydrocarbon, and smoke emissions were decreased in the B20 blend due to the higher oxygen content of the biodiesel. Nevertheless, at 50% and 100% load conditions, Nitric oxide emissions were higher by 9% and 17%, respectively, than diesel fuel. The highest CO2 emission was obtained for B20A25 of 13.5% at 100% load condition. As the acetylene mass share increased, the peak pressure and ignition delay time decreased. The heat release rate also decreased as the mass share of acetylene increased. According to the findings, inducing acetylene with diesel–corn biodiesel would improve the engine's efficiency.
