I-valve ye-EGR - isebenza kanjani i-valve ye-solenoid ye-EGR futhi yenzelweni? Indlela ukususa ukungasebenzi kwayo?

Ukunciphisa ukukhishwa kwezinto eziyingozi ezishintshashintshayo kusukela ekushisweni kukaphethiloli ngesinye isikhathi kwaba yisinyathelo esibalulekile embonini yezimoto. Amadivayisi amaningi namasistimu asetshenziselwa lokhu, njenge:

• UPHONDO;
• i-catalyst;
• isihlungi sezinhlayiyana;
• I-AdBlue.

Izingxenye ezengeziwe enjini kanye nezesekeli zayo ngokuvamile zithinta ukusebenza kwayo, futhi uma zisebenza kahle, azibonakali. Ngesikhathi sokungasebenzi, kuba nzima kakhulu, okwenza impilo ibe nzima kubashayeli abaningi. I-valve ye-EGR eyonakele idala izimpawu ezifana ne-turbocharger ehlulekile.. Ngakho-ke, indlela yokuxilonga kahle inkinga enjini ene-valve ye-EGR?

I-valve ye-EGR emotweni - iyini futhi iyini ngempela?

Isistimu ye-EGR inomthwalo wemfanelo wokufaka kabusha amagesi e-exhaust ngenxa yokushiswa kukaphethiloli kusilinda. Lapho ebuzwa ukuthi kungani i-valve ye-EGR idingeka, impendulo elula ukuthi iklanyelwe ukunciphisa inani lezinto eziyingozi ze-nitrogen-toxic compounds (NOx). Lokhu kungenxa yokwehla kwezinga lokushisa ngaphakathi kwegumbi elivuthayo. Ukuqondisa amagesi e-exhaust abuyele enjinini nokwehlisa izinga lokushisa lomlilo kunciphisa izinga lenqubo ye-fuel oxidation. Isistimu ye-EGR yakhelwe ukudala izimo ezinzima kakhulu zokuhlanganiswa komoyampilo ne-nitrogen, okubuye kube ukunciphisa inani lamagesi ayingozi..

Ukusebenza kwe-EGR enjinini

I-valve ye-solenoid ye-EGR ayiyona idivayisi ehlukile, kodwa isistimu enesibopho sokujikeleza kabusha kwegesi ephumayo.. Kodwa-ke, imvamisa ihlotshaniswa ne-valve ye-EGR, edala izinkinga eziningi. Itholakala phakathi kwama-intake and exhaust manifolds. Ikakhulukazi ezinjinini ezinkulu zikaphethiloli nasezimotweni ezinamayunithi edizili, inokupholisa okwengeziwe. Lokhu kuyadingeka ngenxa yamagesi akhipha umoya ashisa kakhulu ashiya igumbi lokusha kanye nesidingo sokuqondisa kabusha inani elikhulu lawo libuyele kulo.

Ibanga lokusebenza lesistimu ye-EGR lincane ngoba i-valve ye-EGR ngokwayo ayivuli njalo. Ngaphansi kwethonya lesiginali etholwe kusilawuli senjini, i-EGR ivula, ilawula kahle ukugeleza kwamagesi okukhipha umoya. Le nqubo yenzeka kuphela ngesilinganiso somthwalo wenjini, ngoba ukujova amagesi okukhipha igesi ekamelweni elivuthayo kunciphisa inani le-oxygen, ngakho-ke kunciphisa ukusebenza kweyunithi. I-EGR emotweni ayisebenzi ngokungenzi lutho, ebangeni elincane le-rev kanye nomthwalo omkhulu.

I-valve ye-EGR - kanjani ukuhlola ukuthi isebenza?

Kuyadingeka ukuxhuma uhlelo lokuxilonga ukuze kuqinisekiswe ukuthi i-valve ye-EGR iyasebenza.. Uma ungenakho ukufinyelela kukho, ungavele uye esitolo sokulungisa izimoto esiseduze. Nokho, khumbula ukuthi izindleko zokuxilonga okunjalo okungenani zingamashumi amaningana e-zł, kuye ngemodeli yemoto.

Izimpawu ze-valve ye-EGR eyonakele

Izimpawu ze-EGR ezilimele ziyisici futhi ziyabonakala. Ukungasebenzi kahle kwe-EGR kubangela:

• inani eliningi lentuthu emnyama kunodizili;
• ukulahlekelwa amandla ngokuzumayo noma okuphelele;
• izitebele zemoto zingasebenzi. 

Ezimweni ezinjalo, ngokuvamile kuyadingeka ukuhlanza i-EGR.. Njengendlela yokugcina, i-valve ye-EGR idinga ukushintshwa.

Indlela yokuhlanza i-valve ye-EGR?

Akudingekile ukuthi uye kumakhenikha ukuze uhlanze i-valve ye-EGR. Uma okungenani unolwazi oluncane lwezimoto kanye nokhiye abambalwa, ungakwenza ngempumelelo ngokwakho. Ukuzivumelanisa nezimo akudingekile ezinguqulweni ezisebenza ngomshini womoya, nokho, kungase kudingeke kumavalvu esimanje alawulwa nge-elekthronikhi, okungabandakanyi ukuzilungisa okuphumelelayo.

Yini oyidingayo ukuze uhlanze i-valve ye-EGR ngokwakho? 

Okokuqala, i-ejenti yokuhlanza (isibonelo, uphethiloli okhiphayo noma i-nitro thinner), ibhulashi, ama-wrenches wokukhulula i-valve (ngokuvamile i-hex) nama-gaskets. Njengoba sishilo ngenhla, bheka le divayisi phakathi kwe-multifold exhaust kanye ne-intake manifold. Ngemuva kokuyikhipha nokuyikhipha, kubaluleke kakhulu ukuhlanza kuphela ingxenye enesibopho sokuhambisa i-valve, hhayi izakhi ze-pneumatic kanye ne-diaphragm. Zenziwe ngerabha futhi zingalinyazwa uketshezi olunolaka.

Ungamangali uma ngemva kokuhlakazwa ubona umule omningi. Isixazululo esihle ukulungiselela isitsha esingebanzi kakhulu, kodwa esijulile, lapho i-valve ye-EGR icwiliswa khona futhi ishiywe amahora ambalwa noma usuku. Ngale ndlela i-goo emnyama izoncibilika futhi ungakwazi ukuhlanza wonke ama-nooks nama-crannies ngebhulashi. Ngemuva kokuthi umsebenzi usuqedile, qiniseka ukuthi unikeza i-EGR ukusula kahle ngaphambi kokuyibeka emotweni.. Qaphela ama-gaskets amasha.

Indlela yokuhlanza i-EGR ngaphandle kwe-disassembly?

Imikhiqizo etholakala emakethe ivumela ukususwa kwamadiphozithi ekhabhoni nokunye ukungcola ngaphandle kokuhlakaza izingxenye. Yiqiniso, kuzoba nenani elikhulu labasekeli nabaphikisi besinqumo esinjalo, futhi ngamunye wabo uzobe elungile ngokwengxenye. Ukulungiswa ngendlela ye-spray kusetshenziswa ohlelweni lokungena endaweni, kuye ngesidingo sokuhlanza ingxenye ethile. Isicelo senziwa enjinini egijimayo nefudumele ngokuvumelana neziyalezo zomkhiqizi womkhiqizo. Ngezinye izikhathi, esikhundleni sokuhlanza, kungase kwenzeke kumuntu ukuthi avale i-valve ye-EGR. Kuhlanganisani?

I-Jamming EGR - imiphumela emibi. Kudingeka nini ukulungiswa?

Kwabanye abashayeli, ukujamisa i-EGR kunomphumela omuhle kuphela - intuthu encane, akukho zinkinga ngokushintshashintsha kwamandla enjini nokuqedwa kwama-jerks. Kodwa-ke, akukhona nje ngokushayela, ngoba lesi simiso sihlobene nekhwalithi yamagesi okukhipha umoya. I-EGR inciphisa ukukhishwa kwezinto ezinobuthi, ngakho-ke kuyadingeka ukuhambisana nemithethonqubo. Ezimotweni zanamuhla, okuthi, ngaphezu kwe-valve ngokwayo, futhi ibe nenzwa yesikhundla futhi iqaphe izinga lokucindezela komfutho, ukufaka ipulaki ku-valve kuzothinta ukusebenza komhlangano. Ezimweni ezinjalo, inqubo kufanele yenziwe umakhenikha onesipiliyoni ojwayele izinto zikagesi.

Iyini imiphumela yokuvala i-EGR? Ngokuyisisekelo ziphathelene nokuhlolwa kobuchwepheshe. Uma i-diagnostician, lapho ihlola imoto, ithola ukwephulwa okuhlobene nokusebenza (ngokuqondile, ukuntuleka kokusebenza) kwe-valve yokukhipha igesi ephumayo, ngeke iphakamise ukuhlolwa. Ukwengeza, ukwehluleka ukuthobela izindinganiso eziqinile zokukhishwa kwegesi nakho kujeziswa ngamaphoyisa. Ezimotweni ezakhelwe ukulingana, umnikazi angalindela inhlawulo ye-PLN 5.

Ukuvalwa kwe-EGR noma ukushintshwa kwevalvu ye-EGR?

Uma imoto indala futhi imoto ingenayo inzwa ye-EGR, ukuvala i-valve ye-EGR kulula. Ngaphezu kwalokho, ukufaka i-valve ye-EGR kungabiza kakhulu. I-solenoid ye-EGR ingabiza, njengabasebenzi. Yonke into ingaba ama-zloty angamakhulu amaningana. Esikhundleni sokukhokha ukuthenga ingxenye entsha bese ushintsha i-valve ye-EGR, abanye banquma ukuyifaka.

I-EGR solenoid valve plug ku-diesel nophethiloli kanye nemiphumela

Izindleko eziphakeme zokushintsha i-valve ye-EGR, isifiso sokugwema okuphindaphindiwe ngqo phezulu esikhathini esizayo - konke lokhu kwenza abashayeli abaningi banqume ukungaboni, i.e. khubaza i-EGR. Ingabe inayo imiphumela? Kwenzekani uma ucisha i-valve ye-EGR enjinini kadizili noma kaphethiloli? Mhlawumbe... lutho. Umthelela oseceleni wokucisha i-valve ye-solenoid ye-EGR kungase kube ukukhanya hlola injini. Ezimotweni ezintsha, umphumela wokukhubaza i-EGR ungase unciphise ukuzuza kokusebenza ebangeni lejubane eliphakathi nendawo.

Uma ufuna isistimu ye-EGR, okuhlanganisa i-valve ye-EGR nenzwa, isebenze ngokungenasici isikhathi eside ngangokunokwenzeka, zama ukuhlanza i-valve ye-solenoid ye-EGR njalo.
