© 2022 Elsevier LtdThe current test was completed on a three-cylinder, liquid-cooled, naturally aspirated, indirect injection with injector pump on the head, compression ignition (CI) engine at 1500 rpm under changing load conditions. Acetylene was pumped as a secondary gaseous fuel into the intake port at various flow rates, while diesel was fed into the cylinder immediately as a primary fuel. The rate of gas flow was set at 200 g/h and 400 g/h, respectively. Tests were conducted at %0, %25, %50, %75 and %100 load conditions at above acetylene mass. In terms of combustion parameters, the results were assayed and compared. Acetylene induction reduced brake thermal efficiency (BTE) across all load settings. The highest BTE of 34.91 percent was attained for baseline diesel in the experiments. Acetylene is added to diesel fuel causes increased CO, HC, and NOx values when compared to conventional diesel combustion but soot was decreased. On the other hand, there is no significant change in CO2 emissions.
