Ivalve ye-EGR (i-valve ye-gas recirculation exhaust) yimveliso ye-mechatronic efakwe kwi-injini ye-diesel ukulawula ubungakanani begesi yokukhupha i-recirculation ebuyiselwa kwinkqubo yokuthatha.
Ivalve ye-EGR yimveliso ye-mechatronic efakwe kwi-injini ye-diesel ukulawula ubungakanani be-exhaust gas recirculation ebuyiselwa kwisistim yokungenisa. Ngokuqhelekileyo ibekwe kwicala lasekunene le-manifold intake, kufutshane nomzimba we-throttle, kwaye idityaniswe kuyo ngetyhubhu emfutshane yentsimbi ekhokelela kwi-exhaust manifold. Umsebenzi wayo kukulawula ubungakanani begesi ephumayo engena kwi-manifold intake, ukwenzela ukuba umlinganiselo othile werhasi yokukhupha uqukuqelele kwi-intake manifold for recirculation. Ivalve ye-EGR yinto ebaluleke kakhulu kwaye ibaluleke kakhulu kwisixhobo sokubuyisela igesi ephumayo.
Ivalve ye-EGR yahlulwe yaba ziindidi ezimbini: uhlobo lomatshini kunye nohlobo lolawulo lombane.
Ivalve ye-EGR inciphisa ubushushu begumbi lokutsha ngokukhokela irhasi yokuphuma ekhutshwa ekutshisweni kwe-injini ukuya kwindawo eninzi yokuthatha inxaxheba ekutshiseni, ukuphucula ukusebenza kakuhle kwe-injini, ukuphucula imeko-bume yokutsha, kunye nokunciphisa umthwalo i-injini, ngokufanelekileyo ukunciphisa ukukhutshwa kwe-NO iikhompawundi, ukunciphisa ukubetha, kunye nokwandisa ixesha lecandelo ngalinye. ubomi benkonzo.
Igama elipheleleyo yi-Exhaust Gas Recirculation, oko kukuthi, ukukhupha i-gas recirculation [1] Inkqubo isetyenziselwa ukunciphisa ukukhutshwa kwe-nitrogen oxides (NOX) kwi-gas exhaust. I-nitrojeni kunye ne-oksijini ithatha iikhemikhali kuphela phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu, kwaye iqondo lokushisa kunye noxinzelelo kwigumbi lokutsha le-injini lihlangabezana nale miqathango, ngakumbi ngexesha lokunyanzeliswa kokukhawuleza. Xa i-injini isebenza phantsi komthwalo, i-valve ye-EGR iyavula, ivumela i-gas encinci yokukhupha igesi ukuba ingene kwi-manifold intake kunye negumbi lokutsha kunye nomxube otshayo. Ivalve ye-EGR ivaliwe xa ingasebenzi, kwaye igesi encinci yokukhupha iphinda ijikelezwe kwi-injini. I-automobile exhaust gas yigesi engatshiyo (ngaphandle kwepetroli kunye ne-oxidant) engathathi nxaxheba ekutshiseni kwigumbi lokutsha. Inciphisa ubushushu bokutsha kunye noxinzelelo ngokufunxa inxalenye yobushushu obuveliswa kukutsha ukunciphisa imveliso yenitrogen oxides. Ubungakanani begesi yokukhupha igesi engena kwigumbi lokutshisa inyuka ngesantya senjini kunye nomthwalo
I-exhaust gas recirculation yindlela apho inxalenye yegesi yokukhupha ifakwe kwi-air fresh inhaled (okanye umxube) ngexesha lokusebenza kwe-injini, kwaye ibuyele kwi-cylinder ukuze i-recirculation ithathe inxaxheba ekutshiseni. Umsebenzi wayo kukunciphisa ukukhutshwa kwe-NOx. I-NOx yigesi eyingozi kakhulu kumzimba womntu, eyenziwa ngokukodwa phantsi kobushushu obuphezulu kunye neemeko ezinobuncwane be-oxygen. Ngethuba lenkqubo yokusebenza kwe-injini, ukuba inxalenye yegesi yokukhupha iphinda ifakwe kwi-cylinder ngexesha elifanelekileyo kwaye ngokufanelekileyo, kuba icandelo eliphambili legesi yokukhupha inomlinganiselo omkhulu wobushushu obuthile, i-CO2, igesi yokukhupha iyakwazi ukufunxa inxalenye. yobushushu obuveliswa kukutsha kwaye uyikhuphe kwi-cylinder, kwaye ibe nefuthe elihle kumxube. Isiphumo esithile sokuhlanjululwa, ngaloo ndlela sinciphisa ubushushu obuphezulu kunye nomxholo we-oksijini wokutsha kwe-injini, ngaloo ndlela ukunciphisa ukubunjwa kwe-NOx compounds.
Nangona kunjalo, ukuphindaphinda kwegesi ephumayo okugqithisileyo kuya kuchaphazela ukusebenza okuqhelekileyo kwe-injini, ngakumbi xa injini isebenza ngesantya esingasebenziyo, isantya esiphantsi kunye nomthwalo ophantsi kwaye injini isebenza kwindawo ebandayo, kwaye xa amandla enjini efuneka kumthwalo ogcweleyo. (i-throttle epheleleyo), i-recirculation Exhaust gas iya kuba nefuthe elibi ekusebenzeni kwe-injini. Ngoko ke, ubungakanani begesi ephumayo ethatha inxaxheba kwi-recirculation kufuneka ilungelelaniswe ngokuzenzekelayo ngokweemeko zokusebenza zangempela ze-injini kunye notshintsho kwiimeko zokusebenza. Ukuziqhelanisa kubonise ukuba, ngokweendlela ezahlukeneyo ze-injini, isixa segesi ephumayo esibandakanyekayo ekujikelezweni kwakhona sihluka phakathi kwe-6% kunye ne-13%.
Ukuze kwenziwe isixa sokujikeleza kwakhona kwerhasi yokuphuma kwakhona kungabi nempembelelo egqithisileyo ekusebenzeni kwe-injini, iinjini zale mihla ezilawulwa ngombane zikwathatha isicwangciso solawulo esivaliweyo sokuphinda kujikelezwe irhasi, kunye nesivamvo sendawo yevalvu ye-EGR ifakwe kwindawo yokuphuma kwakhona kwerhasi. ivalve (ezinye iimodeli zisebenzisa i-exhaust sensors zegesi). okanye isivamvo soxinzelelo), ulawulo lwengxelo yokulungiswa kwe-loop evaliweyo yemali yokubuyisela igesi yokukhupha iyenzeka.Indawo yokuhamba yeshishini. Ukuphakama komgangatho ukusuka emhlabeni kuphantsi, kwaye izinga lokusetyenziswa kwendawo yangaphakathi liphezulu phakathi kweemveliso ezifanayo, ezingaphezulu kwe-19% kuneemveliso ezifanayo; indawo enkulu.
