Ethanol has higher octane and oxygen properties than fossil-fuel gasoline. Along with the increase in gasoline dependency and exhaust emissions, the use of ethanol as a fuel is urgently studied. This study aimed to observe the concentration of 5% ethanol in gasoline on the performance and exhaust emissions of a 150cc gasoline engine that was operated at 1000, 2000, and 3000rpm. The observation results show that the concentration of 5% ethanol in gasoline correlates with an increase in performance with indications of an increase in EGT, Brake power, BTE, and a decrease in SFC. On the emission side, it is also correlated with an increase in the quality of exhaust emissions with indications of increased CO2 emissions and reduced CO and HC emissions. The best correlation of 5% ethanol concentration was obtained at an operating speed of 2000rpm with an increase in EGT of 10.70%, an increase in Brake power of 9.49%, an increase in BTE of 38.62%, an increase in CO2 emissions of 23.06%, a decrease in SFC of 26 .49%, CO emission reduction of 16.67%, and HC emission reduction of 4.24%.

Researchers are increasingly coming up with creative solutions to reduce fuel consumption and harmful emissions due to the political unrest around crude oil and harsher environmental legislation around the globe. Using gasoline and ethanol blends as substitutes in SI engines is thought to be a promising approach. To lower the cost of experimental test, it is still necessary to provide a model to explore the emissions, performance and combustion of ethanol mixtures in petrol engine under various operating situations. A comprehensive quasi dimensional two zone model was used. This mathematical model could predict and analyze the engine combustion, emissions and performance parameters using MATLAB. The thermal efficiency was improved for E20 by 3%. Ethanol addition decreased SFC value by average 7.2% for E20 with respect to gasoline. In comparison to gasoline, the increases in output power were 1.1%, 3%, 4%, and 5.5% are obtained with E5, E10, E15, and E20. and 45% The highest increases in peak cylinder pressure and cylinder temperature for E20 about gasoline are 14 and 11%, respectively about gasoline. At 2500 rpm, the greatest percentage declines in NOx, CO, and HC emissions for E20 are 3.3, 23.5 and 45% about gasoline. The results of comparing the mathematical model’s validity to those acquired from experimental data and diesel RK software demonstrate that the MATLAB code is appropriate. The mathematical model proved that ethanol blending can be used up to 20% as alternative fuels to improve the gasoline engine performance, combustion and emissions.
