Ukukhumbula ivalve ye-EGR Ngaba kuyimfuneko ukutshintshwa?
Umsebenzi wevalve ye-EGR kunye nefuthe lomonakalo.
Ivalve ye-EGR (i-Exhaust gas recirculation valve) yinto ebalulekileyo yokulawula injini yemoto, efakwe kwi-injini yokulawula ubuninzi be-exhaust gas recirculation ebuyiselwa kwisistim yokungenisa. Xa i-valve ye-EGR yonakalisiwe, iya kukhokelela kwiingxaki ezifana nesantya sokungazinzi, ukukhawuleza okungahambi kakuhle, ukunyuka kokusetyenziswa kwepetroli, kunye nokungonelanga kwamandla. Isizathu sokukhumbula ngokuqhelekileyo kukuba amacandelo angaphakathi e-valve ye-EGR agqweswe yi-chlorine ephezulu kwi-fuel, okukhokelela ekusebenzeni kakubi komzimba we-valve, onokubangela ukungasebenzi kakuhle kwe-injini, kwaye kwiimeko ezinzima, isithuthi sinokumisa. ngezantya eziphantsi, okonyusa umngcipheko wengozi.
Izizathu kunye nemfuneko yokukhumbula
Isizathu sokukhumbula ngokuqhelekileyo kukuba amacandelo angaphakathi e-valve ye-EGR agqweswe yi-chlorine ephezulu kwi-fuel, okukhokelela ekusebenzeni kakubi komzimba we-valve, onokubangela ukungasebenzi kakuhle kwe-injini, kwaye kwiimeko ezinzima, isithuthi sinokumisa. ngezantya eziphantsi, okonyusa umngcipheko wengozi. Ngoko ke, ukutshintshwa ngexesha elifanelekileyo le-valve ye-EGR ngumlinganiselo obalulekileyo wokuqinisekisa ukusebenza okuqhelekileyo kwe-injini kunye nokhuseleko lokuqhuba.
Iinzuzo kunye neengozi zokutshintsha i-valve ye-EGR
Ukutshintsha i-valve ye-EGR kunokuqinisekisa ukusebenza okuqhelekileyo kwe-injini, ukuphepha iingxaki ezifana nesantya esingazinzanga sokungazinzi kunye nokunyuka okungahambi kakuhle, kunye nokunciphisa ukusetyenziswa kwepetroli kunye namandla anganeleyo. Nangona kunjalo, ukutshintshwa kwevalve ye-EGR kufuna iindleko ezithile kunye nexesha, kwaye kunokuba yimfuneko ukuba isithuthi sisetyenziswe ixesha elide okanye sine-mileage eninzi; Nangona kunjalo, ukuba isithuthi sisetyenziselwa ixesha elifutshane okanye sinomgama omncinci, unokucinga ngokuqhubeka usebenzisa iindawo zokuqala zokulungiswa.
Yintoni ivalve ye-egg?
Ivalve yokubuyisela igesi ephumayo
Ivalve ye-EGR yivalve yokukhupha igesi ejikelezayo kwakhona. Yimveliso yokudibanisa i-electromechanical efakwe kwi-injini ye-diesel ukulawula ubungakanani begesi yokukhupha i-recirculation ebuyiselwa kwi-intake system, kwaye yinto ebaluleke kakhulu kunye neyona nto ibalulekileyo kwisixhobo sokubuyisela igesi ephumayo. ...
Umsebenzi ophambili wevalve ye-EGR kukulawula ubungakanani begesi yokukhupha engena kwi-manifold intake, ukwenzela ukuba umlinganiselo othile werhasi yokukhupha uqukuqelele kwi-intake manifold for recirculation. Ngokuqhelekileyo ibekwe kwicala lasekunene le-manifold intake, kufuphi nomzimba we-throttle, kwaye imisela ubungakanani begesi yokukhupha idluliselwe kwi-intake manifold ngeqondo lokuvula ivalve elawulwa yi-vacuum tube. Ngokuyalela irhasi yokuphuma kwi-injini yokutsha ukuya kuninzi lokuthatha inxaxheba ekutshiseni, ivalve ye-EGR inokunciphisa ubushushu begumbi lokutsha, iphucule ukusebenza kakuhle kwe-injini, iphucule indawo yokutsha, nokunciphisa umthwalo wenjini. Ngexesha elifanayo, kunokunciphisa ngokufanelekileyo ukukhutshwa kwe-carbon monoxide compounds, ukunciphisa ukunkqonkqoza, kunye nokwandisa ubomi benkonzo yecandelo ngalinye.
Ukongeza, iivalve ze-EGR zikwahlulahlulwe zaba ziindidi ezimbini zolawulo lomatshini kunye ne-elektroniki ukulungelelanisa iimfuno zeenjini ezahlukeneyo. Kwi-injini yanamhlanje elawulwa nge-elektroniki, ukuze kulawulwe ngokuchanekileyo ngakumbi ubungakanani begesi yokuphuma kwakhona, iqhinga lokulawula i-loop evaliweyo liyamkelwa, kwaye i-sensor yesigaba imiselwe kwivalve ye-EGR ukuva imeko yokusebenza kwe-injini ngokwenyani. ixesha, kwaye ngokutsho kolu lwazi, i-valve ye-EGR ilungelelaniswe ukuze ivule kwaye ivale, ukuze kufezekiswe ulawulo oluchanekileyo lwesixa sokuphindaphinda kwegesi ephumayo.
Ivalve yemoto yophukile ingaba yintoni uphawu enayo?
Zeziphi iimpawu ezicacileyo onokuzifumana xa i-valve ye-EGR yemoto yakho isilela?
I-valve ye-EGR, i-valve ye-gas recirculation system exhaust, xa iphosakele, isithuthi siya kubonakala uluhlu lwezibonakaliso zesilumkiso. Okokuqala, ukungazinzi kokungenzi nto okanye ukuvutha kwedangatye yinto eqhelekileyo, kwaye isibane esinempazamo sinokudanyaza rhoqo ukukukhumbuza ukuba unikele ingqalelo kwisimo senjini. Okwesibini, ngenxa yokuba ukusilela kwevalvu ye-EGR kunokukhokelela ekukhutshweni komgangatho ongekho mgangathweni, isithuthi sinokujongana neentloni zokungaphumeleli uhlolo lonyaka.
Ukuba i-valve ye-EGR igcinwe ivulekile, imiphumo ibaluleke ngakumbi: imoto iya kubonisa umsi omnyama kunye nokungabikho kokukhawuleza, ngelixa ukusetyenziswa kwepetroli kuncipha kwaye ukwanda kwamafutha. Ngokuchasene noko, ukuba i-valve ye-EGR ivaliwe, ukukhutshwa kombhobho kuya kuchaphazeleka kwaye kunokukhokelela ngokuthe ngqo ekungaphumelelini ukuphumelela imigangatho yokuhlola yokuhlolwa konyaka.
Ngokubhekiselele kwizizathu zomonakalo we-valve ye-EGR, kukho imiba emininzi kakhulu: inkunkuma yegesi yokubuyisela kwakhona iingxaki zenkqubo, ukugcinwa okungafanelekanga, umgangatho ophantsi we-oyile kunye nokuguga kwevalve ngokwayo. Umzekelo, ukusetyenziswa kwepetroli ecocekileyo okanye ukongezwa okungafanelekanga kwe-oyile yamafutha kunokuba yinto ekhawulezileyo ebangela ukusilela kwevalve ye-EGR. Iivalvu ze-EGR zisebenza kumaqondo obushushu e-injini aphezulu, kwaye ekuhambeni kwexesha, njengeepadi zokugquma zegumbi levalvu kunye neringi zerabha, ziya kuguga ngenxa yokuguga.
Ngokubanzi, impilo ye-valve ye-EGR ibalulekile ekugcineni ukusebenza kwe-injini kunye nokukhutshwa kokusingqongileyo, xa iimpawu ezingentla zifunyenwe, ukugcinwa kobugcisa kufuneka kufuneke ngokukhawuleza ukuqinisekisa ukuba ukhuseleko lokuqhuba kunye neemfuno zokusingqongileyo zidibene.
