Ukushintsha i-valve ye-EGR - nansi indlela!

I-valve ebizwa ngokuthi i-EGR yenza umsebenzi obalulekile emotweni. Sizokukhombisa ukuthi uyibona kanjani i-valve ye-EGR ehlulekile, indlela yokushintsha i-valve, nokuthi yiziphi izindleko okufanele uzilindele.

Nokho, uma yehluleka, ngeke isakwazi ukwenza lo msebenzi. Lokhu kungaphazamisa ukusebenza kwenjini kanye nempilo yayo. Ngenxa yalesi sizathu, ukukhubazeka kwe-valve ye-EGR kufanele kulungiswe ngokushesha.

I-valve ye-EGR yenza imisebenzi elandelayo

Izinjini zikadizili nezikaphethiloli zinamazinga okushisa afinyelela phezulu I-2500 degrees Celsius .

Ngakho kwakheka i-nitrogen oxides, eyingozi emvelweni futhi kufanele ikhishwe enjinini. ukuthi ukunciphisa inani le-nitrogen oxides ekhishelwa endaweni ezungezile, ingxenye yamagesi aphumayo ibuyiselwa ekuthatheni okuningana ngokusebenzisa lokho okubizwa nge-exhaust gas recirculation (EGR) uhlelo .

Le nqubo kunciphisa kakhulu izinga lokushisa lomlilo futhi ngaleyo ndlela kwakheka ama-nitrogen oxides amancane njengomphumela wenqubo.

Kule nqubo Izilinganiso ze-valve EGR inani lamagesi e-exhaust abuyela enjinini. Uma i-valve ye-EGR ingasakwazi ukwenza imisebenzi yayo ngenxa yokukhubazeka, endaweni Ikhanda lesilinda noma i-turbocharger ama-soot deposits aqoqana, anganciphisa kakhulu impilo yawo yesevisi.

Lezi zimpawu zibonisa ukungasebenzi kahle

Njengoba kunjalo ngezingxenye eziningi zemoto ezibalulekile, Izimpawu eziningi zingabonisa i-valve ye-EGR enephutha .

Nokho, ezinye zalezi zimpawu kungase futhi kube izimpawu zezinye izici . Uma ubona uphawu olunjalo, kufanele futhi unake ezinye izimpawu ukuze ukwazi ukuhlukanisa umonakalo kalula.

Izimpawu ze-valve ye-EGR ehlulekile zihlanganisa:

- Imoto iyagxumagxuma ngenkathi ushayela. - Amandla enjini ancishisiwe. - Awekho amandla aphelele. – Injini iya kwimodi yesimo esiphuthumayo ngaphansi komthwalo. - Amalambu enjini yokuhlola akhanya kafushane lapho injini iqalwa noma ngenkathi ushayela. - Kunentuthu eningi emnyama ephuma epayipini lokukhipha umoya. – Kunyuke kakhulu ukusetshenziswa kukaphethiloli. - Ukukhishwa kwe-nitrogen oxide ephakeme kukalwa ngesikhathi sokuhlolwa kokukhipha umoya.

Uma kwenzeka noma iyiphi yalezi zimpawu, i-valve ye-EGR kufanele ilungiswe noma ishintshwe ngokushesha ngangokunokwenzeka. Ngenxa yemvelo kanye nemoto yakho.

Ingabe i-valve ye-EGR iyingxenye yokuguga?

Lo mbuzo unzima kakhulu. . Empeleni impendulo kumele ibe negative , njengoba i-valve ivame ukugcwala ngokweqile. Nokho, ngokuhamba kwesikhathi, izinhlayiya ze-soot ziqoqana kumagesi okukhipha umoya, okunganciphisa kancane kancane ukusebenza kwe-valve ye-EGR.

Mayelana nalokhu, kungashiwo ukuthi I-valve ye-EGR ngokuqinisekile iyingxenye yokugqoka futhi, kuye ngesitayela sokushayela kanye nemayela, kufanele kushintshwe noma kuhlanzwe kanye noma ngaphezulu phakathi nokuphila kwemoto.

Shintsha i-valve ye-EGR ngokwakho noma uyibuyisele?

Ngokomthetho , ukufaka esikhundleni se-valve ye-EGR ngokwakho akuyona inkinga. Lokhu kungenzeka ngisho nangaphandle kwamathuluzi akhethekile noma ulwazi oluningi. Nokho, lokhu empeleni kusebenza ekushintsheni ngokwako. .

Kusukela ukuhlanza i-valve и ukufakwa kabusha kwe-valve ehlanzekile kufanele kwenziwe kuphela i-workshop yochwepheshe. Ukuhlanza okungalungile kungaholela ngokushesha ekulimaleni okuqhubekayo, okuzothinta kabi ukusebenza kwe-valve ye-EGR.

Eshabhu ungaphinda uhlole ukusebenza kwengxenye usebenzisa amathuluzi afanelekile. Ekhaya, lokhu ngokuvamile akunakwenzeka.

Ngakolunye uhlangothi, ukushintshwa okulula kwengxenye eyisipele akuyona inkinga kubantu abaningi. Nokho, kunomkhawulo owodwa. Kwamanye amamodeli ezimoto ukushintshwa kudinga ukuqaqa uhhafu wenjini. Futhi, kwezinye izimoto, i-valve ye-EGR ingase idinge ukuthi ihlelwe kusengaphambili kusetshenziswa ithuluzi lokuskena. Kulezi zimo, ukuvakashela i-workshop ngokuvamile kuyisinqumo esifanele. , njengoba kukhona zonke izinsiza ezidingekayo namathuluzi.

Ukushintsha i-valve ye-EGR isinyathelo ngesinyathelo

- Njengomthetho, i-valve ye-EGR itholakala phezulu kwe-cylinder block ngqo phambi kwalokho okubizwa ngokuthi i-intake manifold. Njengoba i-valve ye-EGR inesimo esifanayo kuzo zonke izinhlobo zezimoto, kulula ukuyibona. – Khulula ikhava yenjini, uma ifakwe. - Uma i-valve ifinyeleleka kalula, ingasuswa ngokushesha. - Nqamula yonke imigqa ku-valve ye-EGR. - Ungakhohlwa ukususa ama-gaskets futhi. – Thuthukisa izikulufu ezimbili kuya kweziyisishiyagalombili ezibambe i-valve ye-EGR. – Faka i-spare part bese uyilungisa ngezikulufo. – Phinda uxhume amapayipi namagesi. - Hlanganisa zonke ezinye izingxenye bese uqala injini. – Injini manje kufanele isebenze kahle kakhulu.

Naka okulandelayo lapho ushintsha i-valve ye-EGR

- Unganaki i-valve kuphela, kodwa futhi namapayipi nezimpawu. Izigxivizo ezilimele kanye namapayipi e-sooty nawo kufanele ashintshwe uma kunesidingo. - Ngaphambi kokufaka esikhundleni, thatha isithombe se-valve ye-EGR nayo yonke imigqa exhunyiwe. Lokhu kuzokwenza kube lula kuwe ukuzibona lapho uhlanganisa kabusha. – Uma ukufinyelela ku-valve ye-EGR kunzima futhi ukususwa nokufaka kunzima, thintana neshabhu lochwepheshe. Ngale ndlela ungagwema amaphutha okufaka abizayo.

Izindleko Zokucatshangelwa

Ngokuya ngomkhiqizi wemoto kanye nemodeli ethile, amanani entengo yevalvu ye-EGR asuka kuma-euro angama-70 kuye kwangama-350. Uma amapayipi aseduze noma izigxivizo ezixhunyiwe nazo zidinga ukushintshwa, kuzodingeka ulindele cishe ama-euro angama-50–150 ngaphezulu. Uma ukulungiswa kwenziwa endaweni yokusebenzela ekhethekile, bazokhokhisa phakathi kuka-150 no-800 wama-euro ukulungisa kanye nengxenye eyisipele, kuye ngamahora okusebenza. Lokhu kungenxa yokuthi ngisho nase-workshop ekhethekile, ukususa, ukufaka nokuhlola i-valve ye-EGR kuthatha ihora elilodwa kuya kwamathathu okusebenza. Ungakwazi ukwehlisa intengo kancane uma uzilethela ivalvu entsha ye-EGR ngokwakho. Ama-workshops amaningi abiza amanani aphezulu ezingxenyeni ezisele kunasemakethe evulekile.
