Abstract

The growing concern for environmental sustainability and energy security has propelled interest in alternative fuels. This study investigates the performance and emission characteristics of a spark ignition (SI) engine powered by hydrogen-enriched biogas fuel. The research examines variations in brake thermal efficiency, specific fuel consumption, and exhaust emissions under different load conditions and hydrogen-biogas mixing ratios. Results indicate that hydrogen addition improves thermal efficiency and reduces hydrocarbon (HC) and carbon monoxide (CO) emissions, although NOx levels tend to increase. The findings suggest that hydrogen-enriched biogas can serve as a cleaner alternative for future SI engine applications.
