EGR对电喷LPG发动机燃烧过程及NOx排放的影响（Effects of EGR on Burning Process and NOx Emission of Electronic Controlled LPG Injection SI Engine）
废气再循环 电喷LPG发动机 快速燃烧过程 双火花塞
2009/9/2
研究了EGR率的变化对LPG燃气在稀燃条件下的燃烧、排放以及循环变动率的影响。结果表明，基于高能双火花塞点火的快速燃烧系统可以加快LPG燃气的燃烧速率，有效地改善引入EGR的LPG发动机的快速燃烧过程。在整个有效废气再循环率（REGR）范围内LPG稀燃稀限得到较大幅度提高，同时抑制了发动机因高温而生成的NOx。同时，采用快速燃烧系统的最大REGR为8.11%，大于普通方式的5%；LPG燃烧过程的循...
