The use of eco-friendly fuels is essential in meeting the recently strengthened emission regulations. Hydrogen, which has been attracting attention as an eco-friendly fuel, faces problems in handling and storage due to its material properties. Thus, ammonia has been proposed as an alternative. Ammonia can be easily liquefied under room temperature conditions compared to hydrogen, and has high energy density. Accordingly, to review the applicability of ammonia as a fuel for engines, an experiment was conducted on the change in the combustion control factor in the direct injection-type ammonia power plant engine. This experiment was conducted by changing a total of four variables by using ECU: Dwell time and Start of Injection. Combustion stability and the trend in exhaust emissions, such as nitrogen oxide, were observed when ammonia was burned under conditions of 1,500 RPM and part load. By optimizing combustion control factors, finding conditions that allow stable combustion became possible even when only ammonia was used as fuel. Also, there are plans to apply these strategies to expand its operating area in the future. |
