1. Yintoni ivalve ye-EGR
Ivalve ye-EGR yimveliso efakwe kwi-injini ye-diesel ukulawula ubungakanani begesi ephumayo ephinda ijikeleziswe kwi-system yokuthatha. Ngokuqhelekileyo ibekwe kwicala lasekunene le-manifold intake, kufuphi ne-throttle, kwaye idibaniswe nombhobho omfutshane wensimbi okhokelela kwi-manifold exhaust.
Ivalve ye-EGR inciphisa ubushushu begumbi lokutsha ngokukhokela irhasi yokukhupha ukuya kuninzi lokuthatha inxaxheba ekutshiseni, ukuphucula ukusebenza kakuhle kwe-injini, ukuphucula imeko yokutsha, nokunciphisa umthwalo wenjini, ukunciphisa ngokufanelekileyo ukukhutshwa. yeNO iikhompawundi, ukunciphisa knock, kunye nokwandisa ubomi inkonzo yecandelo ngalinye. Igesi yokukhutshwa kweemoto yigesi engatshangayo engathathi nxaxheba ekutshiseni kwigumbi lokutsha. Inciphisa ubushushu bokutsha kunye noxinzelelo ngokufunxa inxalenye yobushushu obuveliswa kukutsha ukunciphisa ubungakanani benitrogen oxide eveliswayo.
2. Yenza ntoni ivalve ye-EGR
Umsebenzi wevalve ye-EGR kukulawula ubungakanani begesi ephumayo engena kwi-manifold intake, ukwenzela ukuba isixa esithile serhasi yenkunkuma iqukuqelele kwi-intake manifold for recirculation.
Xa injini isebenza phantsi komthwalo, ivalve ye-EGR ivulekile, ngexesha elifanelekileyo, ngokufanelekileyo kwinxalenye yegesi yokukhupha kwakhona kwi-cylinder, kuba amacandelo aphambili egesi yokukhupha i-CO2 kunomthamo wobushushu mkhulu, ngoko ke igesi yokukhupha inokuba yinxalenye yobushushu obuveliswayo. ngokutshisa kunye nokuthatha ngaphandle kwe-cylinder, kunye nomxube, ngaloo ndlela ukunciphisa ukushisa kwe-injini kunye nomxholo we-oksijini, ngaloo ndlela ukunciphisa inani le-NOx compounds.
3.Impembelelo ye-EGR valve lag
ImiGangatho yokuKhuphuka VIenI-gine ibeka i-sensor ye-position okanye i-exhaust i-sensor ye-gas okanye i-sensor yoxinzelelo kwi-valve ye-EGR ukuqhuba ukulungiswa kwe-loop evaliweyo kunye nolawulo lwengxelo yexabiso legesi yokukhupha i-recirculation yokwenene. Ngokweemeko zangempela zokusebenza ze-injini kunye nokutshintsha kweemeko zokusebenza, inokulungelelanisa ngokuzenzekelayo inani legesi yokukhupha ebandakanyekayo ekusetyenzisweni kwakhona.
Ukuba ivalve ye-EGR igxininisekile, elona xabiso lerhasi yokukhupha kwi-manifold yokuthatha liya kuba lingalawuleki.
Ukugqithiswa kwerhasi ephumayo ngokugqithisileyo kuya kuchaphazela umsebenzi oqhelekileyo we-injini, kube nefuthe elibi ekusebenzeni kwe-injini, kwaye kuchaphazele amandla ombane enjini, okukhokelela ekunqongophaleni kwamandla e-injini. Inkunkuma encinci kakhulu yerhasi kumjikelezo iya kuchaphazela ubushushu begumbi lokutsha kwe-injini, inyusa ukukhutshwa kwe-NO ikhompawundi, okukhokelela ekubeni izinto ezikhutshwayo azifikeleli kumgangatho, okukhokelela kumda wenjini.
