Emission and pollutants analysis using Ethanol-Gasoline Blends for Single Cylinder Four Stroke Petrol Engines

Present work investigates the impact of ethanol-gasoline blends on emissions and pollutants from single-cylinder 4-stroke petrol engines. The study aims to understand how different ethanol percentages affect engine emissions using various blends ranging from E10 to E30. Emissions were measured using a portable analyzer, encompassing carbon monoxide (CO), nitrogen oxides (NOx), particulate matter (PM), and volatile organic compounds (VOCs). Results indicate that higher ethanol content reduces CO and VOC emissions due to improved combustion efficiency but increases NOx and PM emissions. While ethanol enhances combustion, it also alters combustion characteristics, leading to elevated NOx and PM emissions. Ethanol’s potential as a cleaner fuel is noted, but careful consideration is warranted due to its impact on NOx emissions and environmental concerns associated with production. Continued research is essential to optimize ethanol-gasoline blends for sustainable transportation and mitigate their environmental impacts effectively.
