%X 氨气是重要的零碳替代能源之一&#65292;当前对氨气的研究限于机理和着火性质的探究&#65292;缺乏对发动机的应用研究。本文搭建了甲醇发动机模型&#65292;并通过缸内压力和放热率验证了模型的准确性。在此基础上引入不同浓度(0%&#65292;5%和10%)的氨气分析了缸内压力、放热率、滞燃期、燃烧持续期和缸内温度的变化。研究发现&#65292;添加氨气后&#65292;缸内压力和放热率增大&#65292;滞燃期和燃烧持续期减少&#65292;缸内最大温度升高。<br>Ammonia is one of the important zero-carbon alternative energy sources. The current research on ammonia is limited to the exploration of mechanism and ignition properties, and there is a lack of application research on engines. In this paper, a methanol engine model was built, and the accuracy of the model was verified by the pressure in the cylinder and the heat release rate. On this basis, different concentrations of ammonia (0%, 5% and 10%) were introduced to analyze the changes of cylinder pressure, heat release rate, ignition delay period, combustion duration and temperature in the cylinder. It was found that after adding ammonia gas, the pressure and heat release rate in the cylinder increased, the combustion delay period and combustion duration decreased, and the maximum temperature in the cylinder increased.
