- The second is a cooled exhaust-gas recirculation system that reduces engine pumping losses, which also helps to improve economy. 第二个是一个冷却废气再循环系统,降低发动机泵的损失,这也有助于改善经济。
- Early exhaust valve closing ( EVC ) timings result in high residual fractions in the cylinder, decreasing air mass in cylinder per cycle, increasing combustion duration, and decreasing IMEP while the pumping loss is decreased. 排气门关闭越早,缸内的残余废气量增加,每循环进气量减少,燃烧持续期变长,PIMEP减小,然而泵气损失减小;
- With EGT strategy, the pumping loss is reduced due to the increase of intake manifold pressure, and the increase of intake temperature leads to the complete combustion and high combustion efficiency. 分析表明,废气滞留可以提高进气歧管压力,明显降低泵气损失;混合气温度提高促进燃烧更完全,使燃烧效率得以提高;
- Abstract : Exhaust Gas Trap(EGT) is more effective strategy for mixture dilution and heating, and it is beneficial to reduce pumping loss and fuel consumption than Exhaust Gas Recirculation ( EGR ). 摘要 :废气滞留(EGT)比传统的废气再循环(EGR)具有更好的稀释和加热混合气作用,有利于减小汽油机中小负荷泵气损失,降低油耗。
- Even an oversight in the design might issue in heavy losses. 设计中那怕是一点点疏忽也可能造成重大的损失。
