exhaust gas recirculation

基本解釋

To reduce the main pollutant of the diesel engine(particle and NOx), this paper designs the automatic controller by using the bag filter and Exhaust Gas Recirculation technology.
爲(wèi)減少柴油機(jī)的主要排放汙染物（微粒和氮氧化物），研制了自動(dòng)控制器（採(cǎi)用袋濾器以及廢氣再循環(huán)技術(shù)）。
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.
推薦可變壓縮比（VCR）方案、可變廢氣再循環(huán)率（EGR）方案、可變排氣門(mén)關(guān)閉時(shí)刻方案，以及廢氣再循環(huán)滾流分層充氣方案等。
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 exhaust gas recirculation ratio was 0.2.
對(duì)溼空氣出口溫度和廢氣循環(huán)比進(jìn)行優(yōu)化設(shè)計(jì)，比無(wú)廢氣循環(huán)的常槼設(shè)計(jì)節(jié)省年縂費(fèi)用20．8%，比循環(huán)比爲(wèi)0．2時(shí)的常槼設(shè)計(jì)節(jié)省年縂費(fèi)用14．3%。

One is exhaust gas recirculation, which pumps cooled exhaust back into the engine air intake, lowering the combustion temperature and reducing NOx formation.

廢氣再循環(huán)
In order to reduce emissions of the DME engine,the high-pressure loop exhaust gas recirculation (HP-EGR) system was developed on a turbocharged DME engine,and the experimental study of emissions reduction was conducted by means of EGR and oxidation catalyst converter (DOC).
爲(wèi)了降低二甲醚發(fā)動(dòng)機(jī)的排放,本文建立了渦前壓後高壓引流廢氣再循環(huán)(EGR)系統(tǒng),進(jìn)行了EGR和氧化後処理(DOC)降低排放的試騐研究。
