Research Status and Development Trend of Hydrogen and Hybrid Hydrogen IC Engines

目前,氢燃料发动机发展迅速,本文总结了国内外在此领域的发展现状,分析了目前存在早燃、回火、功率密度低、储运难、NOx排放高等问题,重点介绍了汽油混氢的可行性与研究现状,并指出了未来先进氢燃料发动机的发展方向。

The development of hydrogen -fueled internal combustion engine is rapid. This paper reviews the research and development of Hydrogen IC engines. Preignition, backfire, low power density, hard storage and transport and high NOx emissions are the difficult problems. This paper highlights the research and feasibility of hydrogen as fuel additive to gasoline, i.e. hybrid gasoline and hydrogen IC engines. Finally, several advanced hydrogen engines are discussed and suggestions are given for future work.
