Özet

In this study, a single-cylinder diesel engine, normally running on diesel fuel, was converted to ammonia-diesel dual fuel. The effects of ammonia fuel at different energy content levels (0 %, 5 %, 10 %, 15 %, and 20 %) were investigated on thermal efficiency, CO, THC, NOx, and smoke emissions. Subsequently, GWP (Global Warming Potential) emission values and tax calculations were performed. Furthermore, economic and exergy analyses were performed using the present value method for converting the engine to ammonia-diesel dual fuel. Finally, the economic analysis was re-conducted by calculating the carbon tax based on the GWP emission value. Based on the results, the lowest GWP emission values were obtained with the addition of ammonia at 10 % energy content.
