Valofo ea EGR ke pelo ea tsamaiso ea enjene ea ho ntša metsi ka morao. EGR e khuts'oane bakeng sa Exhaust Gas Recirculation, 'me ke sona seo e se etsang. Sesebediswa sena se tsotehang se baballang tikoloho se bulwa maemong a itseng a tshebetso ya enjene mme se dumella digase tsa exhaust hore di boele di boele di kgutlisetswe enjeneng kgetlo la bobedi. Ts'ebetso ena e fokotsa haholo mesi e kotsi ea nitrogen oxides (NOx), e tlatsetsang haholo ho theheng mosi. Sehloohong sena, u tla fumana tlhahisoleseding e mabapi le mosebetsi oa valve ea EGR, hammoho le mokhoa oa ho hloekisa valve le hore na ke hobane'ng ha hangata e hloka ho hloekisoa kapa ho nkeloa sebaka.
Sephahla sa EGR se phela bophelo bo thata. Ha e le hantle, mohlomong ke e 'ngoe ea likarolo tse rarahaneng ka ho fetisisa tsa enjene ea morao-rao. E lula e otloa ka mocheso o chesang ka ho fetisisa oo koloi e ka o etsang 'me e tletse likaroloana tsa mafura a sa chesoang, a tsejoang ka ho fetisisa e le carbon. Valofo ea EGR e tiisitse hoo e ka laoloang ke vacuum ea enjine kapa komporo, ha e ntse e khona ho mamella mocheso oa khase e nang le khabone e tletseng likhase tse 1,000 nako le nako ha enjene e sebetsa. Ka bomalimabe, ho na le moeli ho ntho e 'ngoe le e' ngoe, ho kenyelletsa le valve ea EGR.
Ka mor'a lipotoloho tse likete, carbon e qala ho kenya li-deposit ka har'a valve ea EGR, e fokotsa bokhoni ba valve ho etsa mosebetsi oa eona e le molebeli oa heke oa EGR. Li-deposit tsena tsa carbon li ntse li hola le ho hola ho fihlela valve ea EGR e emisa ho sebetsa hantle. Sena se ka lebisa mathateng a fapaneng a ho sebetsana le mathata, ha ho le e 'ngoe ea tsona e lakatsehang. Ha ho se sebetse hona ho etsahala, ho na le litlhare tse peli tse ka sehloohong: ho hloekisa valve ea EGR kapa ho nkela sebaka sa EGR sebaka.
Karolo ea 1 ea 2: Ho hloekisa valve ea EGR
Lisebelisoa tse hlokahalang
- Lisebelisoa tsa mantlha tsa letsoho (li-ratchets, sockets, pliers, screwdrivers)
- Carburetor le throttle cleaner
- Scraper gasket
- lisebelisoa tsa nko ea nale
- Liatlana tsa rabara
- Likhalase tsa tšireletso
- borashe bo bonyenyane
Mohato oa 1 Tlosa lihokelo tsohle tsa motlakase.. Qala ka ho tlosa likhokahanyo leha e le life tsa motlakase kapa li-hoses tse khomaretsoeng ho valve ea EGR.
Mohato oa 2: Tlosa valve ea EGR enjeneng.. Ho rarahana ha mohato ona ho itšetlehile ka mofuta oa koloi, hammoho le sebaka le boemo ba valve.
Hangata e na le liboutu tse peli ho isa ho tse 'ne tse e tšoereng ho manifold e kenang, hlooho ea silinda kapa phala ea exhaust. Lokolla liboutu tsena 'me u tlose valve ea EGR.
Mohato oa 3: Lekola likou tsa li-valve bakeng sa li-block le li-deposit.. Hape hlahloba likou tse tsamaisanang le enjene ka boeona. Hangata li koaleha ka carbon hoo e ka bang boholo ba valve ka boeona.
Haeba e koalehile, leka ho ntša likotoana tse kholo tsa khabone ka pliers ea nko ea nale. Sebelisa carburetor le throttle body cleaner hammoho le borashe bo bonyenyane ho hloekisa mesaletsa efe kapa efe e eketsehileng.
Mohato oa 4: Hlahloba valve ea EGR bakeng sa li-depositi.. Haeba valve e koalehile, e hloekise ka ho feletseng ka carburetor le choke cleaner le brush e nyenyane.
Mohato oa 5: Sheba tšenyo ea mocheso. Lekola valve ea EGR bakeng sa tšenyo e bakiloeng ke mocheso, lilemo, 'me ho hlakile hore carbon buildup.
Haeba e senyehile, e tlameha ho nkeloa sebaka.
Mohato oa 6: Hloekisa gasket ea valve ea EGR.. Hloekisa sebaka sa gasket holim'a valve ea EGR le enjene e nang le gasket scraper.
Hlokomela hore u se ke ua kenya likotoana tse nyane tsa gasket likoung tsa EGR ka lehlakoreng la enjene.
Mohato oa 7: Kenya sebaka sa li-gaskets tsa EGR.. Hang ha ntho e 'ngoe le e' ngoe e hloekisitsoe le ho hlahlojoa, nka sebaka sa EGR gasket (s) 'me ue kopanye le enjene ho litlhaloso tsa fektheri.
Mohato oa 8: Hlahloba ho lutla. Lekola ts'ebetso ho latela bukana ea litšebeletso tsa feme 'me u hlahlobe hore na ho na le vacuum kapa exhaust leaks.
Karolo ea 2 ea 2: Phetoho ea valve ea EGR
Ka linako tse ling li-valve tsa EGR li ka ba bothata ho nkeloa sebaka ka lebaka la lilemo, boemo kapa mofuta oa koloi ka boeona. Haeba u na le bothata ka mehato e ka tlase, ho molemo ho bona setsebi kamehla.
