通过试验验证了利用富氧进气提高进气道喷射氢内燃机功率的可行性，进行了氢气-空气样机试验和30%、40%进气氧浓度试验，并基于这些数据搭建并标定了发动机一维仿真模型。结果表明：当量比为0.7时，进气氧浓度增至30%，功率平均提高20.5%，有效热效率平均降低2%；进气氧浓度增至40%，功率平均提高36.5%，热效率降低4%。该结果可以指导下一步更高进气氧浓度的氢内燃机试验，并且为改善进气道喷射氢内燃机的动力性提供了一种新方法。

The feasibility of using oxygen-enriched air to increase the power of intake-port hydrogen injection internal combustion engine was verified by experiments. Hydrogen-air prototyping tests and 30%, 40% intake oxygen concentration tests were conducted. Based on these data, the one-dimensional simulation model of engine was built and calibrated. The results show that the power increases by 20.5% and the brake thermal efficiency decreases by 2% on average when the equivalence ratio is 0.7 and the intake oxygen concentration increases to 30%. The power increases by 36.5% and the thermal efficiency decreases by 4% when the intake oxygen concentration increases to 40%. The results can guide the future tests of engine with higher intake oxygen concentration and provide a new method for improving the power of intake-port hydrogen injection internal combustion engine.
