Ukulungiswa kwe-valve ku-VAZ 2107

Ukulungisa ama-valve ku-VAZ 2107 akunzima. Nokho, uzodinga izingxenye ezisele nezinto zokwakha, kanye nemiyalelo enemininingwane.

Amathuluzi ayadingeka nezinto zokwakha

Ngaphambi kokuba uqale ukulungisa ama-valve, kufanele uthole amathuluzi alandelayo nezinto zokwakha:

1. Iqoqo lama-probes okulungisa izikhala (noma i-micrometer kanye nesitimela). Leli ithuluzi eliyinhloko emsebenzini. Kumele kube ngekhwalithi enhle, akufanele uthenge ama-probe kumkhiqizi ongabazisayo.
2. Isethi yama-wrenches avulekile, usayizi ophakathi (10-19 mm).
3. I-gasket yesivalo se-valve. Kungcono ukukhetha i-gasket kumkhiqizi omuhle: i-Corteco noma i-Elring.
4. Hlanza amanikiniki noma amathawula ephepha.
   

   Isethi ye-feeler gauge iyithuluzi eliyinhloko lokulungisa ukucaciswa kwama-valve.

I-Valve Adjustment Imiyalelo

Ama-valve alungiswa enjini ngezinga lokushisa elingekho ngaphezu kwama-20 ^oC. Enjinini eshisayo, akunakwenzeka ukwenza ukulungiswa kwekhwalithi ephezulu kwama-valve - lokhu kubangelwa ukunwetshwa kwensimbi lapho kushisa. Ukuze unqume izinga lokushisa kwenjini, beka intende yesandla sakho phezu kwesembozo se-valve - akufanele zizwe ukufudumala, ukupholisa kufanele kuvele ensimbi yesembozo se-valve. Umsebenzi wenziwa ngokulandelana okulandelayo.

1. Susa isihlungi somoya kanye nendlu, bese uqaqa amantongomane angu-8 uvikela ikhava yevalvu enjinini.
   

   Amantongomane okubopha ikhava ye-valve atholakala eduze komjikelezo wawo
2. Ngemva kokususa isembozo se-valve, sibona inkanyezi ye-camshaft nezingalo ze-rocker. Ngaphambi kokulungisa ama-valve, kuyadingeka ukuthi usethe isilinda senjini yesine endaweni ephezulu efile (TDC). Ukuze wenze lokhu, vula i-crankshaft ngokwewashi kuze kube yilapho uphawu lwenkanyezi ye-camshaft lufanelana ne-ebb ekhethekile ngaphansi kwesembozo sevalvu, futhi uphawu oluku-crankshaft pulley luhambisana nophawu olukhethekile ebhulokhini lenjini.
   

   Ukuze ulungise ama-valve, injini kufanele ifakwe endaweni lapho amamaki okulungiswa okukhethekile ahambisana nomunye nomunye.
3. Ngemva kokumisa isilinda sesine ku-TDC, sithatha i-probe futhi sihlole igebe phakathi kwekhamera ye-camshaft kanye ne-valve rocker kumakhamera No. 6 no-8. Izinombolo zekhamera zibalwa ngokulandelana kusukela kunkanyezi. Ukushisa okushisayo kwama-valve ku-VAZ 2107 kufanele kube ngu-0,15 mm.
   

   Igebe kumakhamera wesithupha nesishiyagalombili kufanele libe ngu-0,15 mm
4. Uma igebe lihluka esilinganisweni, kufanele lilungiswe. Ukuze wenze lokhu, khulula i-nati yokukhiya ephansi, bese usetha imvume edingekayo nge-nati ephezulu. Ngemva kwalokho, hlola ukulungisa okulungile nge-feeler gauge. I-probe kufanele ingene ngokuqinile, kodwa ngaphandle kwe-jamming.
   

   Ukulungiswa kwegebe kwenziwa yinati eliphezulu elinezinsimbi zokukhiya ezixegayo
5. Zungezisa i-crankshaft ngamadigri angu-180 futhi ulungise ama-valve No. 4 no-7.
6. Phinda uvule i-crankshaft ingxenye yokujika bese ulungisa ukuphuma kwamavalvu No. 1 no-3.
7. Futhi uphinde uvule i-crankshaft ngamadigri angu-180 futhi ulungise imvume yokushisa kuma-valve No. 5 no-2.

Izimpawu ze-valve stem

Ngenkathi ulungisa ama-valve, kungenzeka ukuthi ubungazi nokuthi ubuseduze nenye into ebaluleke kakhulu yomshini wokusabalalisa igesi - ama-valve stem seal.

Izigqoko ze-oil scraper zitholakala eziqwini ze-valve zomshini wokusabalalisa igesi

Inhloso yezimpawu zamafutha

Lapho injini isebenza, i-camshaft, izingalo ze-rocker, ama-valve spring nama-valve top asebenza enkungwini kawoyela. Amafutha afakwa kuzo zonke izingxenye nezindlela ezitholakala ngaphansi kwesembozo se-valve. Ngokwemvelo, ibuye iphelele phezulu kwama-valve, okuthiwa iziqu.

Ngaphansi kwethonya lamandla adonsela phansi, uwoyela uzovame ukuphumela egumbini elivuthayo. Njengoba wazi, akufanele kube khona. Izigqoko ze-oil scraper zenzelwe ukuvimbela uwoyela ukuthi ungangeni phansi esiqwini se-valve ungene egumbini elivuthayo lenjini.

Ukungasebenzi kahle kwenjini okuhambisana namakepisi agugile

Okuwukuphela kwenhloso ye-valve stem seal ukuvimbela uwoyela ukuthi ungangeni endaweni evuthayo yenjini.. Ngokuhamba kwesikhathi, irabha yalesi sici ilahlekelwa imisebenzi yayo futhi iwa ngaphansi kwethonya lendawo enolaka. Lokhu kuholela ekungeneni kwamafutha engxube ye-air-fuel, lapho evutha khona ngempumelelo.

Ukuze injini serviceable, ukusetshenziswa uwoyela kufanele kube mayelana 0,2 - 0,3 amalitha ngayinye 10 amakhilomitha ayizinkulungwane. Ngama-valve stem seal agugile, ingafinyelela ilitha eyodwa ngamakhilomitha ayinkulungwane.

Ukushiswa kukawoyela kumasilinda:

• ivala futhi ibhubhise abaguquli be-catalytic kanye nezihlungi ze-particulate (amadivayisi anciphisa okuqukethwe kwezinto eziyingozi kumagesi okukhipha amandla), okuyizinto ngokwazo ezibiza kakhulu;
• kubangela ukushisa ngokweqile kanye nokwehluleka ngaphambi kwesikhathi kwama-valve okukhipha injini;
• kwandisa kakhulu i-opacity ye-exhaust;
• kwandisa ingozi yokulamba kwamafutha enjini ngenxa yokuntuleka kukawoyela.

Insiza ye-valve stem seal ezimotweni ezifuywayo ishintshashintsha cishe ngamakhilomitha ayizinkulungwane ezingu-80. Le parameter incike kakhulu kwikhwalithi yama-caps ngokwawo kanye namafutha asetshenzisiwe.

Yiziphi izesekeli ezingcono kakhulu ukuzisebenzisa

Njengamanje, imikhiqizo yemikhiqizo eyaziwa kakhulu njenge-Corteco ne-Elring yizona ezithenjwa kakhulu abathanda izimoto kanye namakhenikha - lezi zinhlobo ziye zazibonakalisa zivela ohlangothini olungcono kakhulu ekukhiqizeni ama-gaskets, ama-oil seals, ama-seal, ama-valve stem seal.

Kunemikhiqizo yabakhiqizi basekhaya emakethe. Izinga labo liyahlukahluka kakhulu, kodwa nokho liyasilela kwikhwalithi yemikhiqizo yezinkampani eziholayo.

Ungashintsha kanjani ama-oyela seals

Isihloko sokushintsha ama-valve stem seal sibanzi futhi sifanele i-athikili ehlukile. Kafushane, kwenziwa kanje.

1. Susa ikhava ye-valve.
2. Susa i-sprocket ye-camshaft.
   

   Ukuze ususe inkanyezi ye-camshaft, kuyadingeka ukukhulula i-bolt eyibambe nge-washer yokukhiya
3. Susa i-camshaft emibhedeni yabo.
   

   Ukuze ususe i-camshaft, udinga ukukhulula ama-bolts avikela izindlu zamabheringi ayo.
4. Sekela ama-valve ngenduku yethini nge-spark plug kahle.
   

   Ukuvimbela ama-valve ukuba angawi, adinga ukusekelwa nge-tin bar.
5. Yomisa i-valve.
   

   Ukucindezela isiphethu se-valve, ama-crackers adinga ukukhishwa ngaphandle kwe-groove
6. Faka esikhundleni se-oil seal.
   

   Isigxivizo samafutha esidala sisuswa ngezikulufu ezimbili.

UKUSHINTSHWA KWE-OIL CAPS VAZ CLASSIC

Isivalo se-valve

Isembozo se-valve sivikela indlela yokusabalalisa igesi emathonyeni angaphandle, futhi ivimbela ukuvuza kwamafutha. I-valve cover gasket yakhelwe ukuvala ukuhlangana kwesembozo se-valve ngekhanda lesilinda. Iwuchungechunge lwenjoloba, olumise ngokulandela umphetho wekhava yevalvu.

Esikhundleni se-gasket lekhava ye-valve

Uma kukhona ukuvuza kwamafutha ngaphansi kwesembozo se-valve, i-gasket kufanele ishintshwe. Ukuze wenze lokhu, udinga ukususa ikhava ye-valve (usuvele wazi ukuthi ungakwenza kanjani lokhu kusukela esigabeni sokulungisa ama-valve) kanye ne-gasket. I-gasket entsha ifakwe ngaphandle kwamathuluzi noma izinto ezikhethekile.

I-valve cover gasket ibekwe phezu kwekhanda le-cylinder ngesandla, ngaphandle kwamathuluzi.

Indawo yokufaka kufanele ihlanzwe kahle kusukela ezinsalela ze-gasket endala kanye neminonjana ye-sealant. Sifaka i-gasket entsha endaweni bese sifaka ikhava ye-valve enjinini.

Ukuhleleka kokuqinisa ikhava ye-valve

Ngemva kokufaka ikhava ye-valve enjinini, kufanele ivikelwe ngamantongomane ekhanda le-cylinder. Ukuze uvimbele ukuhlanekezela, ukufuduka kanye nokulimala kwe-gasket, kunenqubo ekhethekile yokuqinisa amantongomane. Ingqikithi yale nqubo ukuqinisa ama-fasteners ukusuka phakathi nendawo kuya emaphethelweni.

1. Qinisa inadi eliphakathi.
2. Qinisa inadi eliphakathi nendawo.
3. Qinisa amantongomane angaphandle ohlangothini olulodwa lwekhava.
4. Qinisa amantongomane angaphandle ngakolunye uhlangothi lwekhava.
5. Qinisa inadi kuthebhu yekhava yevalvu.
   

   Amantongomane ekhava ye-valve kufanele aqiniswe ngendlela ethile ukuze agweme ukuhlanekezela nokuguqulwa kwe-gasket.

Ngokulandela ukuqiniswa komyalelo wamantongomane, uqinisekisiwe ukugwema izinkinga ezilandelayo ngokuvuza kwamafutha ngaphansi kwesembozo se-valve.
