Study of the Effect of Bioethanol Fuel on the Generation of Emissions from the Small Mobile Electric Generator

Abstract

This thesis investigates the impact of bioethanol fuel on the emissions produced by small mobile electric generators. Amidst growing concerns about environmental sustainability and the adverse effects of traditional fuels, bioethanol presents a viable alternative due to its renewable nature and potential for reduced emissions. The study specifically examines how blends of bioethanol and gasoline influence the emission of pollutants such as carbon monoxide, unburnt hydrocarbons and carbon dioxide when used in a four-stroke, single-cylinder carbureted petrol engine.

Through rigorous experimental testing, the thesis evaluates the combustion characteristics and emissions of a typical spark ignition engine running on pure gasoline and various bioethanol-gasoline mixes. This includes an analysis of specific fuel consumption and engine efficiency when a constant load of 790 Watts is given to the generator, providing a comparative assessment against traditional gasoline. The results of these tests are intended to determine the feasibility of bioethanol as a substitute for gasoline and to understand its implications for emission levels and engine performance.

This work contributes to the ongoing discourse on alternative fuels, offering insights into the adjustments necessary for existing engine designs to accommodate bioethanol. It also explores the broader implications for emissions policies and the practical aspects of using bioethanol in small-scale generators. Recommendations for future research and applications in commercial and environmental contexts are discussed, highlighting the role of bioethanol in achieving more sustainable energy solutions.
