Ivalvu ye-EGR (ivalvu yokubuyisela igesi ephumayo) yimveliso ye-mechatronic efakwe kwinjini yedizili ukulawula ubungakanani bokubuyisela igesi ephumayo kwinkqubo yokungenisa.
Ivalvu ye-EGR yimveliso ye-mechatronic efakwe kwinjini yedizili ukulawula ubungakanani bokujikeleza kwegesi ephumayo ebuyiselwa kwinkqubo yokungenisa. Ihlala ikwicala lasekunene le-intake manifold, kufutshane nomzimba we-throttle, kwaye iqhagamshelwe kuyo ngetyhubhu emfutshane yesinyithi ekhokelela kwi-intake manifold. Umsebenzi wayo kukulawula ubungakanani begesi ephumayo engena kwi-intake manifold, ukuze inani elithile legesi ephumayo lingene kwi-intake manifold ukuze ijikeleze kwakhona. Ivalvu ye-EGR yinxalenye ebaluleke kakhulu nebalulekileyo kwisixhobo sokujikeleza kwegesi ephumayo.
Ivalvu ye-EGR yahlulwe yaba ziintlobo ezimbini: uhlobo loomatshini kunye nohlobo lolawulo lwe-elektroniki.
Ivalvu ye-EGR inciphisa ubushushu begumbi lokutsha ngokukhokela igesi yokukhupha umoya ekhutshwa kukutsha kwenjini ukuya kwi-intake manifold ukuze ithathe inxaxheba ekutsha, iphucule ukusebenza kakuhle kwenjini, iphucule imeko yokutsha, kwaye inciphise umthwalo kwinjini, inciphise ngempumelelo ukukhutshwa kwee-NO compounds, inciphise ukungqongqoza, kwaye yandise ixesha lenkonzo yecandelo ngalinye.
Igama elipheleleyo yi-Exhaust Gas Recirculation, oko kukuthi, i-exhaust gas recirculation [1] Le nkqubo isetyenziselwa ukunciphisa ukukhutshwa kwe-nitrogen oxides (NOX) kwi-exhaust gas. I-nitrogen kunye ne-oxygen zisabela ngokwekhemikhali kuphela phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu, kwaye ubushushu kunye noxinzelelo kwigumbi lokutsha lenjini ziyahlangabezana nezi meko, ngakumbi ngexesha lokukhawuleziswa okunyanzelekileyo. Xa injini isebenza phantsi komthwalo, ivalvu ye-EGR iyavuleka, ivumela inani elincinci legesi yokutsha ukuba ingene kwi-intake manifold kwaye ingene kwigumbi lokutsha kunye nomxube otshayo. Ivalvu ye-EGR ivaliwe xa ingasebenzi, kwaye igesi yokutsha encinci ijikeleziswa kwinjini. Igesi yokutsha yemoto yigesi engatshiyo (engenamafutha kunye ne-oxidant) engathathi nxaxheba ekutshisweni kwigumbi lokutsha. Inciphisa ubushushu bokutsha kunye noxinzelelo ngokufunxa inxalenye yobushushu obuveliswa kukutsha ukuze kuncitshiswe imveliso ye-nitrogen oxides. Ubungakanani begesi yokutsha engena kwigumbi lokutsha buyanda ngesantya senjini kunye nomthwalo.
Ukujikeleza kwakhona kwegesi yokukhupha umoya yindlela apho inxalenye yegesi yokukhupha umoya ifakwa emoyeni omtsha ophefumliweyo (okanye umxube) ngexesha lokusebenza kwenjini, ize ibuyiselwe kwisilinda ukuze iphinde ijikelezwe ukuze ithathe inxaxheba ekutshisweni. Umsebenzi wayo kukunciphisa ukukhutshwa kwe-NOx. I-NOx yigesi eyingozi kakhulu emzimbeni womntu, eveliswa ikakhulu phantsi kobushushu obuphezulu kunye neemeko ezityebileyo zeoksijini. Ngexesha lokusebenza kwenjini, ukuba inxalenye yegesi yokukhupha umoya ibuyiselwa kwisilinda ngexesha elifanelekileyo nangendlela efanelekileyo, kuba icandelo eliphambili legesi yokukhupha umoya linomthamo omkhulu wobushushu, i-CO2, igesi yokukhupha umoya inokufunxa inxalenye yobushushu obuveliswa kukutsha kwaye iyikhuphe kwisilinda, kwaye inefuthe elihle kumxube. Isiphumo esithile sokuxuba, ngaloo ndlela kunciphisa ubushushu obuphezulu kunye nomxholo weoksijini wokutsha kwenjini, ngaloo ndlela kunciphisa ukwakheka kweekhompawundi ze-NOx.
Nangona kunjalo, ukujikeleza kwegesi ephumayo kakhulu kuya kuchaphazela ukusebenza okuqhelekileyo kwenjini, ingakumbi xa injini isebenza ngesantya esingasebenziyo, isantya esiphantsi kunye nomthwalo ophantsi kwaye injini isebenza kwimeko yokubanda, kwaye xa amandla enjini efuneka kumthwalo opheleleyo (i-throttle epheleleyo), ukujikeleza kwegesi Igesi ephumayo iya kuba nefuthe elikhulu ekusebenzeni kwenjini. Ke ngoko, ubungakanani begesi ephumayo ethatha inxaxheba ekujikelezeni kufuneka buhlengahlengiswe ngokuzenzekelayo ngokweemeko zokusebenza zenjini kunye notshintsho kwiimeko zokusebenza. Ukuziqhelanisa kuye kwabonisa ukuba, ngokwezakhiwo ezahlukeneyo zenjini, ubungakanani begesi ephumayo ebandakanyeka ekujikelezeni ngokubanzi buhluka phakathi kwe-6% kunye ne-13%.
Ukuze ubungakanani bokujikeleza kwegesi ephumayo bungachaphazeli kakhulu ukusebenza kwenjini, iinjini zanamhlanje ezilawulwa ngombane nazo zisebenzisa icebo lokulawula i-closed-loop yokujikeleza kwegesi ephumayo, kwaye i-EGR valve position sensor ifakiwe kwi-exhaust gas recirculation valve (ezinye iimodeli zisebenzisa ii-exhaust gas sensors). okanye i-pressure sensor), ulawulo lwempendulo yokulungiswa kwe-closed-loop lwe-recirculation yegesi ephumayo lwenziwa. Indawo yokuhamba ngeshishini.
