摘要
随着碳中和战略推进,氢气发动机作为清洁能源技术备受关注。基于CONVERGE软件建立了氢气直喷发动机模型,对燃烧过程中的缸内最大平均温度和最大压力进行模拟分析,揭示了空气压力、氢气温度和氢气压力对燃烧特性的影响。研究结果表明,随着氢气压力和氢气温度的增加,缸内最大压力和最大平均温度都呈现出先增加后降低的趋势。随着空气压力的增加,缸内最大压力呈现出持续增大的趋势,但缸内最大平均温度呈现出降低的趋势。研究可为氢气直喷发动机的设计和性能提升提供理论支撑,对推动氢气直喷发动机的实用性和商业化具有重要的实践意义。
With the advancement of carbon neutrality strategies,hydrogen engines have garnered significant attention as a clean energy technology.This study establishes a hydrogen direct injection engine model based on CONVERGE software to simulate and analyze the in-cylinder maximum average temperature and maximum pressure during the combustion process,revealing the influences of air pressure,hydrogen temperature,and hydrogen pressure on combustion characteristics.The findings indicate that as hydrogen pressure and hydrogen temperature increase,both the in-cylinder maximum pressure and maximum average temperature exhibit a trend of initially rising and then declining.With increasing air pressure,the in-cylinder maximum pressure shows a continuous upward trend,while the maximum average temperature tends to decrease.This research can provide theoretical support for the design and performance enhancement of hydrogen direct injection engines,offering significant practical implications for advancing the practicality and commercialization of hydrogen engines.
