Abstract
The blending of ethanol with imported gasoline types has been compulsory since January 1, 2018, with the Communiqué No. 30098 published in the Official Gazette in Turkey. In line with this, it is aimed to determine the effects of gasoline-ethanol blends on engine performance and exhaust emissions resulting from the use of an SI engine. The experiments were performed at different speeds for different ethanol-gasoline blends (E0, E10 and E20) under full load in a four-stroke, single-cylinder engine. As a result, air-fuel mixture ratios, torque, power, vibration and noise values, specific fuel consumption, harmful gas emissions (CO, HC, CO2 and NOx) was measured. Measurements were obtained with 96% accuracy. In this study, carbon monoxide and hydrocarbon emissions decreased, carbon dioxide and nitrogen oxide emissions increased by the addition of ethanol to gasoline. On the other hand, the addition of ethanol has also led to a certain increase in brake specific fuel consumption, vibration and noise levels.

The more studies and developments for the internal combustion engines (ICEs) have gained momentum after the late of the 1800s
The popularity of ICEs and its use in most sectors have caused great energy consumption and undoubtedly played a leading role of the most of the depleting fossil fuel sources [3] because ICEs have been powered by the burning of the fossil fuels and the reserves of the fossil fuels have a finite
This study mainly focused on experimentally investigation and comparing the motor performance by using various rates of ethanol and gasoline blends
Summary
The more studies and developments for the internal combustion engines (ICEs) have gained momentum after the late of the 1800s. The Impacts of Ethanol - Gasoline Blended Fuels on the Pollutant Emissions and Performance of a Spark -Ignition Engine: An Empirical Study chemical representation of CH3OH), respectively. It is possible to come across many studies focusing on engine performance effects, such as vibration and noise, exhaust gas emissions of fuel types and mixtures [14]. In comparison with gasoline alone, using a higher rate of alcohol into gasoline can clearly make the air quality better [25] Based on these literature studies, it is clearly understood that the use of ethanol and gasoline blended fuels in engines can effectively cause the lower the harmful exhaust gas emissions without any modifications in the vehicular systems and fuel tank as well. It is thought that the amount of ethanol blended into gasoline and diesel will be increased due to the negative effects of fossil fuels on the environment and human health, the decrease in the reserves of fossil fuels and the increasing oil prices
