研究了单缸高速汽油机燃用不同浓度氢气时的燃烧和排放特性。将传统的化油器式汽油机改造成电控发动机，利用ECU控制汽油的喷射时刻和持续时间。发动机保持在3000 rpm的恒定速度和全开节气门位置。实验结果表明，氢气的添加量在20%以下时，放热率和缸内压力均有所增加。与纯汽油发动机运行相比，CO和HC的排放量大大降低，而NOx的排放量增加与氢的添加。
The present article aims at characterizing the combustion and emission parameters of a single cylinder high speed SI engine operating with different concentrations of hydrogen with gasoline fuel. The conventional carburetted SI engine was modified into an electronically controllable engine, wherein ECU was used to control the injection timings and durations of gasoline. The engine was maintained at a constant speed of 3000 rpm and wide open throttle position. The experimental results demonstrated that heat release rate and cylinder pressure were increased with the addition of hydrogen until 20%. The CO and HC emissions were reduced considerably whereas NOx emission was increased with the addition of hydrogen in comparison with pure gasoline engine operation.
