I-cooler ye-EGR iyithuluzi elisetshenziselwa ukunciphisa ukukhishwa kwezinjini ezivuthayo zangaphakathi, ezisebenza ngokunciphisa ukukhiqizwa kwe-nitrogen oxides (NOx) ngenqubo ye-exhaust gas recirculation (EGR), lapho amagesi e-exhaust epholiswa khona bese ebuyiselwa enjini ukuze ashiswe.
I-cooler ye-EGR ngokuvamile iqukethe isishintshi sokushisa lapho amagesi e-exhaust, uma ekhishiwe epayipini le-exhaust lenjini, ashintshisana nendawo yokupholisa (imvamisa amanzi okupholisa injini noma umoya) ukuze kwehliswe izinga lokushisa lamagesi aphumayo. Ukwehlisa izinga lokushisa kwegesi yokukhipha kusiza ukunciphisa ukukhiqizwa kwe-NOx, okukhuthazwa izimo zokushisa eziphezulu.
Ngokusebenza ne-EGR epholile, injini inganciphisa ukukhishwa kwe-NOx ngezinga elithile, ngaleyo ndlela ihambisane nezindinganiso zokukhishwa kwemvelo. Ngesikhathi esifanayo, i-cooler ye-EGR iphinde isize ukuthuthukisa ukusebenza kahle kwenjini nokunciphisa ukusetshenziswa kukaphethiloli.
Ama-cooler e-EGR ezimoto zezentengiselwano,Sihlinzeka ngezinto ezisezingeni eliphezulu zama-coolers e-EGR (amakamelo angenisayo naphumayo, amagumbi okungenisa nokukhipha amanzi).
Izingxenye zethu (igumbi legesi) kuyo yonke i-EGR epholile idlala indima ekuxhumekeni, uhlangothi lokungenisa umoya lusetshenziselwa ukuxhuma igesi yokukhipha ngembobo eyindilinga ukuze kufakwe i-valve ye-EGR, ukucutshungulwa kwendawo eyisicaba kuyo yonke inqubo yokuxhuma ukuze kudlale indima yokuvala; imbobo yesikwele ngokusebenzisa i-high-temperature brazing exhunywe kugobolondo; impahla yi-ZG08Cr18Ni9, into ekwazi ukumelana nokugqwala, ukumelana nokushisa okuphezulu, okusiza ekuthuthukiseni impilo yesevisi yezingxenye
Singakwazi ukuhlinzeka lezi zingxenye ngezindlela ezahlukene ngokuvumelana nezidingo zekhasimende.
