摘　　要：以1台2.0 L氢内燃机为测试对象,对其点火能量进行了试验研究,探讨了点火能量对功率的影响及最小点火能量随当量浓度、转速和负荷的变化关系。试验表明:点火能量对氢内燃机的功率影响不大;最小点火能量随转速的增加而减小,随负荷的增加先增加而后降低;在Φ<1的范围内,最小点火能量随当量浓度的增加而减小。For a 2.0 L hydrogen internal combustion engine,the ignition energy was researched by the experiment,the influence of ignition energy on power was discussed,and the correlation of minimum ignition energy with equivalent concentration,speed and load was analyzed.The results show that the influence of ignition energy on hydrogen internal combustion engine power is slight.The minimum ignition energy decreases with the increase of speed and first increases and then decreases with the increase of load.When the parameter Φ is smaller than the value 1,the minimum ignition energy decreases with the increase of equivalent concentration.
