摘要
研究了用两段喷射控制分层混合气形成的基本规律,经调节确定了最佳喷油时间和喷油比例,经初步匹配优化使这种GDI燃烧系统的燃油消耗率比常规进气道喷射汽油机降低15%～24%.
The basic law of stratified mixture forming control by two-stage injection is studied. The injection timings and fuel quantity rations of two injections are optimized. Through the preliminary matching and optimization, the specific fuel consumption can reduce by 15%～24% compared with PFI gasoline engine.
