摘要
氢燃料发动机具有排放低和燃烧效率高等优点,但由于氢气具有点火能量小,火焰传播快的特点,造成氢燃料内燃机易发生早燃。本文对低转速下的氢燃料内燃机利用三维模拟软件进行模拟、分析,研究早燃对氢燃料发动机状态参数的影响。
Hydrogen engine has the advantages of low emission and high combustion efficiency, but due to the character-istics of hydrogen with small ignition energy and fast flame propagation speed, the preignition of hydrogen engine is easyto occur. In this paper, the three-dimensional simulation software is adopted to simulate and analyze hydrogen internalcombustion engine with low speed, thus studying the influences of preignition on hydrogen engine state parameters.
