An Experimental Investigation of The Performance Indicators of Gasoline Engine with Octane Number Additive

This study analyses the impact of a commercial octane number additive on the performance metrics of a spark-ignition engine in addition to measuring gas emissions. The effective conditions with the lowest gas emissions are investigated using five different volumes of octane number additive to local fuel ranging from 100 to 400 ml, and ten different engine speeds ranging from 1000 to 5500 rpm. It is looked at how well the gasoline engine performs in terms of torque, braking force, fuel consumption particular to the brakes, and the emissions of CO, CO2, N2O, and un-burned hydrocarbon. The results indicate that adding a commercial octane number additive to the local fuel has increased engine performance indicators and simultaneously decreased gas emissions. To guarantee the highest performance indicators of the gasoline engine and the minimal level of exhaust gasses, a certain volume of octane number additive and speed engine should be used.
