正时策略对进气道喷射氢气发动机混合气形成、性能与排放的影响
Effect of timing strategy on mixture formation, performance and emission of inlet injection hydrogen engine
为了研究影响进气道喷射氢气发动机性能与排放的因素，利用一维软件GT-POWER建立四缸进气道喷射氢气发动机模型，分析了不同过量空气系数与正时策略（进气门开启正时、喷射正时以及点火正时）对氢气发动机混合气形成、性能与排放的影响。结果表明：基于五十铃JE4N28的氢气发动机稀燃极限在过量空气系数2.0-2.5之间；提前20℃A打开进气门有利于提升氢气发动机热效率、减少NOx排放，最高减幅可达20.6%，且提前打开进气门可以减弱喷氢正时对氢气发动机性能…查看全部>>
In order to study the factors that affect the performance and emission of the Port Fuel Injection hydrogen engine（PFI-H2ICE）, a four-cylinder intake jet hydrogen engine model was established using the one-dimensional software GT-POWER, and the effects of different excess air coefficients and timing strategies (intake valve opening timing, injection timing and ignition timing) on the formation, performance and emission of the hydrogen engine mixture were anal…查看全部>>
