Variable EGR
英 美
An electronic controlled system with variable EGR ratio is built.
建立了一种排气再循环变egr率控制系统。
Schemes of variable compression ratio (VCR), variable exhaust gas recirculation (EGR), variable exhaust valve timing, and EGR with stratification by tumble charge flow are recommended.
推荐可变压缩比(VCR)方案、可变废气再循环率(EGR)方案、可变排气门关闭时刻方案,以及废气再循环滚流分层充气方案等。
