Isibani se-valve se-EGR: indlela yokusivala?

I-valve ye-EGR iyisistimu enciphisa ukukhishwa kwe-nitrogen oxide emotweni yakho. Ngeshwa, ingahluleka ngenxa yekhabhoni ekhiqizwa lapho injini isha. Kulokhu, ukukhanya kwenjini kuphaneli yensimbi kungase kuvele, okubonisa inkinga nge-valve ye-EGR.

💡 Liyini isibani sevalve yokukhipha igesi ephumayo?

La I-valve ye-EGR iyithuluzi lokulawula ukungcola. Kuyimpoqo ezimotweni ezinezinjini zikadizili nezinye izinjini zikaphethiloli. Ngenxa ye-valve yayo, iqondisa kabusha amagesi kagesi angashile ngemva kokusha esikhumulweni sezindiza ukuze ashiswe okwesibili.

Lokhu kuvutha kwesibili kunciphisa ukukhishwa kwezinto ezingcolile emotweni yakho, ikakhulukazi ama-nitrogen oxides noma i-NOx.

Kodwa-ke, ukusebenza kwe-valve ye-exhaust gas recirculation kwenza kube lula kakhulu ukwakheka i-calamine, umule omnyama owakhayo futhi ongavimba i-exhaust gas recirculation flap.

Kulokhu, ukukhanya okuyisixwayiso kungase kubonise ukungasebenzi kahle. Kodwa imoto yakho ayinaso isibani esiyisixwayiso esiklanyelwe ngokukhethekile i-valve ye-EGR. Eqinisweni kunjalo ukukhanya kwesixwayiso senjini yini ekhanyisayo.

Ngakho-ke, lokhu kukhanya okuyisixwayiso kungabonisa inkinga nge-valve ye-EGR kanye nolunye uhlobo lokungasebenzi kahle. Ngakho-ke, umakhenikha uyokwenza ukuzihlola funda amakhodi wephutha futhi uthole ukuthi i-valve ye-EGR iyiphutha yini.

Uma ukukhanya kuza ngaphandle kokuhlanza isikhathi eside, ungakwazi ukufinyelela ngokuqondile i-valve yokukhipha igesi ephumayo. Uma imbozwe nge-limescale, inkinga izobonakala ngeso lenyama.

🚗 Ngingakwazi ukushayela ngikhanyise ilambu eliyisixwayiso le-exhaust gas recirculation?

Uma i-valve ye-exhaust gas recirculation inesici, ukukhanya kwesexwayiso senjini kuyakhanya. Ivamise ukuvezwa ngombala osawolintshi-ophuzi kuphaneli yokulawula. Uma lesi sibani esiyisixwayiso sibabomvu, imoto yakho iyangena umbuso owehlisiwe : ngeke ukwazi ukufunda ukudla okuthile noma umbiko othile.

Kulokhu, kuzoba nzima ukushayela. Lokhu futhi akukhuthazwa kakhulu: inkomba ebomvu kubha yamathuluzi ikhombisa inkinga enkulu futhi kufanele ikwenze ukuthi uyeke. immédiatement.

Uma ukukhanya kwenjini kukhanyisa inhlaka, kungase kubonise ukungasebenzi kahle kwevalvu ye-EGR. Nokho, okunye ukwehluleka nakho kungenzeka. Ngempela, le nkomba ingavela futhi uma kunezinkinga ezihlobene nayo isihlungi sezinhlayiyana, Ku Uphenyo lweLambda, Ine inzwa...

Le nkomba izokhanyisa ukuze ikuxwayise ngenkinga enkulu. Uma ideshibhodi yakho ngezinye izikhathi ingakutshela ezimotweni zakamuva kakhulu ukuthi kuyinkinga ye-valve ye-EGR, ngeke uqiniseke kuze kube yilapho usebenzisa ukuxilonga egaraji.

Akuphephile ukuqhubeka nokushayela isibani senjini sikhanyisiwe, kungakhathaliseki ukuthi i-valve ye-EGR noma cha. Eqinisweni, uzibeka engcupheni yokulimaza ingxenye enephutha noma ngisho nenjini yakho kancane. Ukuze uvikele oomakhenikha, imoto yakho ingase futhi iye kumodi eyonakele.

Uma ngempela kuyi-valve yokukhipha igesi ephumayo, ungase uhlangabezane nezinkinga ezilandelayo uma uqhubeka nokushayela nenkomba ekhanyisiwe:

• Ukwehla kokusebenza kanye nama-jerks ;
• Qeda intuthu ;
• Sondeza isithombe ukungcoliswa kwemoto yakho ;
• Ukusetshenziswa kukaphethiloli ngokweqile.

Ngaphezu kwalokho, ngeke uphumelele ekuhlolweni kobuchwepheshe uma uba nezinkinga ngomshini wakho wokulwa nokungcola, okuhlanganisa nevalvu ye-EGR.

🔍 Ungasivala kanjani isibani esiyisixwayiso se-valve ye-EGR?

Isibani esiyisixwayiso se-valve ye-EGR isibani esiyisixwayiso senjini. Njengoba lokhu kungase kubonise ezinye izinkinga, kufanele uqale ngokwenza ukuzihlola. Amakhodi wephutha azokhombisa uma inkinga iku-valve ye-EGR.

Uma kunjalo, unezinketho ezimbili ngokuya ngesimo se-valve yakho yokukhipha igesi ephumayo:

1. Ivalvu yokukhipha igesi ephumayo ivimbekile ngoba ingcole kakhulu : Ukwehliswa kuzoxazulula inkinga futhi kucime isibani.
2. I-valve yokubuyisela igesi ephumayo ilimele : idinga ukushintshwa ukuze kucishwe isibani esiyisixwayiso, ngoba ukwehlisa ngeke kwanele.

👨‍🔧 Ivalvu yokukhipha igesi ephumayo ishintshiwe, kodwa inkomba ihlala ivuliwe: yini okufanele uyenze?

Uma isibani senjini sikhanya ngenxa yenkinga ye-valve ye-EGR, ukwehlisa noma ukubuyisela ingxenye kufanele ngokuvamile kulungise inkinga futhi kucishwe ukukhanya.

Uma inkomba ihlala ngemuva kokuhlanza i-valve yokukhipha igesi ephumayo noma ngemva kokuyishintsha, lokhu kungase kube ngenxa yenkinga. awuzange uvele ku-valve yakho ye-EGR... Lokhu kungenxa yokuthi ilambu lesexwayiso senjini lingase likhanyise ngenxa yokunye ukungasebenzi kahle.

Ukuzihlola kufanele kwenziwe ukuze kuqinisekiswe ukuthi inkinga iku-valve ye-EGR. Uma ungazange uqedele lesi sinyathelo ngaphambi kokufaka i-valve ye-EGR, kungenzeka ukuthi uphuthelwe inkinga.

Uma isibani sakho esiyisixwayiso sisavuliwe ngemva kokufaka i-valve yokukhipha igesi ephumayo futhi uqinisekile ukuthi lokhu bekuyimbangela yenkinga, kungase kudingeke ukuthi hlela kabusha ikhompuyutha yakho injini.

Manje uyazi ukuthi hlobo luni lokukhanya olufikayo uma kwenzeka ukungasebenzi kahle kwe-valve ye-EGR! Uyazi futhi ukuthi uyicisha kanjani. Uma unenkinga yevalvu yokukhipha igesi ephumayo, dlula kusiqhathanisi sethu segaraji ukuze silihlanze noma lishintshwe ngentengo engcono kakhulu.
