Uyishintsha nini i-valve ye-EGR?

Ivalvu ye-EGR emotweni yakho iyisisetshenziswa esiklanyelwe ukunciphisa ukungcola okuphuma emotweni yakho. Zonke izimoto ezintsha zifakwe i-valve ye-EGR. Lapha kulesi sihloko wonke amathiphu ethu mayelana nokuthi ungayishintsha nini i-valve ye-EGR!

🚗 Iyini indima ye-valve yokukhipha igesi ephumayo?

Ivalvu ye-EGR, emele i-Exhaust Gas Recirculation, iyingxenye ebalulekile yokukhawulela ukungcoliswa kwemoto yakho. Ngempela, ngemithethonqubo eqinile yokukhishwa kwe-nitrogen oxide (i-Euro 6 ejwayelekile), zonke izimoto manje sezifakwa i-valve ye-EGR ukususa izinhlayiya eziningi ngangokunokwenzeka.

Ukusebenza kwayo kulula: i-valve yokukhipha igesi ephumayo ivumela amanye amagesi akhipha umoya ukuthi aqondiswe kabusha enjinini ukuze ashise izinhlayiya ezisele, kunokuba aziphonse emkhathini. Ngakho-ke, lokhu kuvutha kwesibili kwegesi yokukhipha kunciphisa inani lezinhlayiya ezikhishwayo kanye nenani le-nitrogen oxide (NOx).

Ngakho-ke, i-valve ye-recirculation ye-exhaust itholakala phakathi kwe-multifold exhaust kanye ne-multifold intake. Iqukethe i-valve system ekuvumela ukuthi ulawule inani legesi elijovwe enjinini.

Kodwa-ke, i-valve yokukhipha igesi ephumayo inenkinga eyodwa kuphela enkulu: ukungcoliswa kwenjini. Ngempela, ngokuhamba kwesikhathi, i-valve ye-EGR ingavala ama-injection akho futhi ivalwe ngamadiphozithi ekhabhoni. Ngakho-ke, kubalulekile ukugcina kahle i-valve yakho ye-EGR ukuvimbela ukuvala: uma i-valve yakho ye-EGR ivinjiwe endaweni evaliwe, imoto yakho izongcolisa kakhulu, uma ikhiyiwe endaweni evulekile, uhlelo lokuthatha lungalimala futhi luvalwe. . ngokushesha. Ngakho qiniseka ukuthi uhlola ukuthi uhlelo lwakho lokulawula ukungcola luyasebenza yini.

???? Yiziphi izimpawu ze-valve ye-EGR engcolile noma evalekile?

Njengoba sisanda kubona, i-valve yakho ye-EGR isengozini enkulu yokuvala nokuvala uma ungayisevisi njalo. Kunezimpawu ezimbalwa ezingakuxwayisa ngevalvu ye-EGR engasebenzi:

• Izilungiselelo zenjini;
• Isivinini senjini esingazinzile;
• Ukulahlekelwa amandla ngesikhathi sokusheshisa;
• Ukukhishwa kwentuthu emnyama;
• Ukusetshenziswa ngokweqile kukaphethiloli;
• Isibani senkomba ephikisana nokunukubezeka sivuliwe.

Uma uhlangabezana nanoma yiziphi izimpawu zayo, kungenzeka ukuthi i-valve yakho ye-EGR ivalekile futhi ingcolile. Sikweluleka ukuthi uye ngokushesha egaraji ukuze uhlanze noma ufake i-valve ye-EGR ukuze ungalimazi injini nesistimu yomjovo.

.️ Indlela yokwandisa impilo yesevisi ye-valve yokukhipha igesi ephumayo?

Ngokwesilinganiso, i-valve yokukhipha igesi yokukhipha igesi inomsebenzi wokuphila cishe we-150 km. Kodwa-ke, i-valve ye-exhaust gas recirculation ingavaleka ngokushesha kuye ngesitayela sakho sokushayela. Ngempela, uma ushayela kuphela ushayela emadolobheni ngesivinini esiphansi, i-valve yakho ye-exhaust gas recirculation izovala ngokushesha ngoba yilapho injini ikhiqiza khona ikhabhoni nokungcola okuningi.

Ngakho-ke, kunezixazululo ezi-2 zokwandisa impilo ye-valve ye-EGR futhi ugweme ukuvala. Okokuqala, yehlisa injini kanye nesistimu yokukhipha umoya njalo. Eqinisweni, ukwehliswa kuvumela ukwehliswa okuphelele ngokujova isihlanzi ngqo kusistimu yokukhipha umoya.

Okokugcina, isixazululo sesibili ukushayela njalo ngesivinini esiphezulu emgwaqeni omkhulu ukuze ukhiphe ikhabhoni futhi ukhiqize kabusha isihlungi se-diesel particulate kanye ne-catalyst. Eqinisweni, njengoba injini yakho ivuka, iyasha futhi isuse ikhabhoni enamathele kumjovo wakho noma kusistimu yokukhipha umoya.

Ungathola umhlahlandlela wethu wokuthi ungayihlanza kanjani i-valve yokukhipha igesi ephumayo noma ubuyisele i-valve yokukhipha igesi ephumayo ngokwakho. Ngempela, khumbula ukuhlanza kuqala i-valve ye-EGR ngaphambi kokuyishintsha, ngoba ezimweni eziningi i-valve ye-EGR iyasebenza, kodwa ivalekile kuphela futhi ingcolile.

???? Kubiza malini ukufaka esikhundleni se-valve yokukhipha igesi?

Ngokwesilinganiso, lindela phakathi kuka-€ 100 no-€ 400 ngokushintshwa kwevalvu yegesi ephumayo. Kodwa-ke, izindleko zokushintsha i-valve ye-exhaust gas recirculation ziyahlukahluka kuye ngokuthi hlobo luni lwe-valve nendawo yalo. Ngempela, kwamanye amamodeli emoto, izindleko zabasebenzi ziningi ngenxa yobunzima bokufinyelela i-valve ye-EGR. Ungahlola ku-Vroomly ukuthi iyiphi intengo engcono kakhulu yokushintshwa kwevalvu ye-EGR yemodeli yemoto yakho eseduze nawe.

Thola amagaraji ezimoto angcono kakhulu eduze nawe endaweni yethu yesikhulumi futhi uqhathanise amadili abanikazi begalaji ukuze uthole intengo engcono kakhulu yokubuyisela i-valve ye-EGR. I-Vroomly inikeza ukonga okuphawulekayo ezindlekweni zokulungisa noma zokulungisa i-valve yokukhipha igesi. Ngakho-ke ungabe usalinda bese uqhathanisa izinsiza zemoto ezihamba phambili ukufaka i-valve yakho ye-EGR.
