This study examined the impact of varying concentrations of ammonia-borane (AB) in gasoline on engine performance and emissions across different load conditions. Four fuel formulations were tested: pure gasoline (G100) and gasoline blends containing 10%, 15%, and 20% AB (AB10, AB15, AB20). Increased AB concentration resulted in higher brake-specific fuel consumption (BSFC). While exhaust gas temperatures were highest with G100 (730.9 °C at full load), the AB blends, particularly AB20, exhibited lower temperatures, with a maximum reduction of 13.8%. The AB20 blend demonstrated elevated BSFC and increased oxygen (O₂) emissions but significantly reduced carbon monoxide (CO) emissions, with up to an 88.2% decrease at full load. Nitrogen oxide (NO x) emissions were generally lower for all AB blends. The highest NO x value was measured with G100 fuel at full load, while the lowest NO x value was measured with AB10 fuel. Under these conditions, a 23% decrease in NO x value was observed with AB10 fuel compared to G100. The engine's thermal efficiency decreased with AB blends at all load levels compared to pure gasoline. Thermal efficiency decrease of 13.76%, 22.32%, and 30.88% occurred for AB10, AB15 and AB20, respectively compared to G100.Overall, incorporating AB in gasoline reduced thermal efficiency and led to a notable decrease in NO x , hydrocarbons (HC), and CO emissions. [Display omitted] • Alcohol-gasoline blend fuels AB10, AB15 and AB20 were created. • All blended fuels were tested in a single cylinder gasoline engine. • AB blends show higher brake specific fuel consumption (BSFC) values compared to pure gasoline. • AB10, AB15 and AB20 showed lower thermal efficiency compared to G100 at all engine loads. • AB blends reduced harmful emissions such as CO, HC and NOx.
