The key to an EGR system is introduced, and the control of exhaustgas quantity recirculation quantity of that in every point at best.
EGR系统的关键就是控制废气的引入量,使废气的再循环量在每一个工作点都达到最佳状况。

The annual total cost of optimum design decreased by 20.8% than that of conventional design without EGR, 14.3% than that of conventional design when exhaustgasrecirculation ratio was 0.2.
Schemes of variable compression ratio (VCR), variable exhaustgasrecirculation (EGR), variable exhaust valve timing, and EGR with stratification by tumble charge flow are recommended.
