摘要
通过1台点燃式进气歧管喷射氢燃料发动机的最大燃烧压力的试验分析,获得了不同工况下的最大燃烧压力循环变动系数,以此为基础研究了过量空气系数、点火提前角以及转速对氢燃料发动机燃烧循环变动的影响趋势。结果表明,点火提前角对氢燃料发动机循环变动的影响相对较大。
On a spark ignition engine with the intake manifold hydrogen injection, the maximum combustion pressure was analyzed and its cyclic variation coefficients were acquired. Based on this, the influences of excess air ratio, spark advance angle and engine speed on cyclic variration was analyzed. The results show that the advance angle has great influence on cyclic variations of hydrogen engine.
