Valve imvume: kufanele kube kanjani? Iziyalezo efanele ukulungiswa valve futhi Vaz izimoto

injini yemoto ifakwe valve ezimbili noma ngaphezulu isilinda ngayinye. Omunye ngoba itheku ingxube ukukhwezelwa uMbhalo. Omunye ungumbonisi ngokuchitha qeda amagesi. ukukhuluma Ngokomthetho, bebizwa "isibalo sabahlengikazi abaqeqeshwayo futhi qeda valve." Negesi ukusatshalaliswa indlela motor usetha ukulandelana yabo wokuvula iphuzu elithile isikhathi valve.

Njengoba injini imoto, izingxenye zalo netindlela bavezwa okushisa aphakeme, ku ukusatshalaliswa igesi valve kuthiwa uma ukulungisa indlela ukuthungela izikhala.

Misalignment nemiphumela

Lapho ezishisayo umphini imvume izinguquko ngesikhatsi kokuhlinzwa isikhathi eside noma ngesikhathi ukungasebenzi izingxenye system, kakhulu ziyancipha motor kahle nemitfombolusito izingxenye. Liphinde ihambisane nohlelo anda petrol kanye nobuntu engqongqoza egumbini engine. Uma, ukwenza isibonelo, igebe ngenhla evamile, element alikwazi ukuvulwa ngokugcwele, futhi lokhu kusenza sibe nokwehla kwamandla izici. Burning the valve futhi isihlalo kungenzeka endabeni igebe encane kakhulu. Kunoma ikuphi, le amaphutha nethonya elibi injini impendulo ngokucindezela isinyathelo namafutha.

iseluleko professional

Ngakho akuvamile ukuhlangabezana nale nkinga, sincoma njalo, cishe njalo ngemva 30 000 km imoto, hlola okuyinto nokusulwa ku valve. Uma kudingeka, kufanele kubhekwe ukusebenza kwezikole zokusoka.

Ukubeka igebe

Okokuqala udinga uqaphele amaphuzu ezibalulekile eziningana phakathi idatha ukulungisa. Okokuqala, kubalulekile ukuba afeze ukulungiswa kuphela injini abandayo. Okwesibili, kubalulekile ukwazi ukuthi kunezinhlobo ezahlukene obandayo Ubukhulu, okufanayo kusebenza izinhlobo Uphawu lezimoto I-valve ezahlukene (eyanele, qeda).

Kukhona futhi izinjini angadingi ukulungiswa ngezikhathi backlashes. Lokhu kungenxa ukuklanywa indlela ukusatshalaliswa igesi. Amaphayiphu kuthiwa actuated ngenxa adjusters ukuqhuma nakho, nxephezela igebe nge amafutha engine. Kulokhu, impilo efana inkonzo mayelana 60 000 km, konke kuncike umenzi kanye nesitayela ukushayela. Lokhu kubuyekeza izokwethulwa imiyalelo imininingwane sendlela ukusebenzisa ukuhlela backlashes ezishisayo valve izinjini Vaz kanti ezinye izimoto. Ukuze afeze lo msebenzi, ngaphezu ukuthenga ezintsha ikhava gasket valve, ngoba ngemva kokuqeda ikhava olwengeziwe ukuvuza kungenzeka ezimpawu uwoyela.

Clearance uhlolwa wokulinganisa Uphenyo ekhethekile, ukushuba zazo kumelwe ihambisane nezidingo lobuchwepheshe brand lesitsite semoto.

Inqubo ukulungiswa

Ngokuyinhloko ukufakwa umphini nqubo azihlukile kakhulu kuye ngokuthi injini, futhi ubukeka mayelana efanayo.

Okokuqala sidinga ukuletha piston we isilinda, okuzokwenza obushintshekayo kuya phezulu maphakathi efile ngesikhathi unhlangothi kokucindezelwa. Kuleli qophelo eyanele kanye qeda valve lizovalwa futhi rocker yabo ingalo kumelwe uqhubekele radially ngaphakathi imvume isethi.

Ngokulandelayo, ukukhululwa ukulawula nut ku screw ukulungiswa. Faka dipstick phakathi cam we camshaft futhi ekupheleni valve, bese esebenzisa screw ukulungisa bese ufake Kunconywa igebe zakontrogayte isikulufa. Lapho afakwe kahle, olawula uphenyo kufanele uhambe esikhaleni ngomzamo nje omncane. Uma kukhona ngisho iphutha kancane, udinga rerun inqubo yokusetha.

Sengiphendukile injini phezu eziyikhulu namashumi ayisishiyagalombili kanye degrees, obukwenza ku uMbhalo esilandelayo. Kubalulekile acabangele oda umsebenzi isilinda imoto injini.

Ukubeka igebe Vaz "ayisishiyagalolunye"

Valve imvume Vaz-2109 ilawulwa ukukhethwa kanye ukufakwa ukuqondiswa ekhethekile. Faka kwabo phakathi nesikhathi sokuphela-valve futhi cam camshaft.

Ukufaka imvume edingekayo - inqubo elula wenziwa, kodwa kudinga ukunakekelwa okukhethekile komfundi indlela enembile ndaba.

Amathuluzi nezinsiza

Ukuze afeze umsebenzi odingekayo ukuba amathuluzi amaningana nezinsiza:

• Isethi ejwayelekile izikhiye.
• Isethi lokulawula iphenya.
• Zibekele imigomo ukulungisa.
• Idivayisi for umphini cutoffs.

ngokushesha inqubo

Okokuqala, asuse cap valve. Ngenxa yalesi pre ahlukanisa lemifanekiso air kwezezindlu, kanye nasezinhlelweni Breather tube drive mpintsha ikhebula.

Ukuze ukukala igebe phakathi valve isilinda kuyadingeka ngezikhathi pheqela crankshaft. Kanjalo futhi kuskrolelwa kalula, kutuswa uyasikrufulula zonke plugs inhlansi.

Okulandelayo, susa esivikelo ikhava plastic ibhande isikhathi. Khona-ke pheqela crankshaft ohlangothini ngokwewashi kuze emamaki umdlalo phezu sprocket camshaft nge uphawu ekhaveni metal. Kunconywe ukuze ujike nut crankshaft isondo lokugijimisa indiphi elenzelwe into esindayo ngoba generator, esebenzisa lesi sihluthulelo ukuze nesikhombisa.

Ngemva kwesikhashana nje kwaqondana amalebula udinga ukukhanyisa kushaft has prongs ezintathu isikhathi drive ibhande.

Ngemva umsebenzi wokwenza amalungiselelo kungenzeka ukukala imvume qeda valve e uMbhalo kuqala futhi itheku lwesithathu. Optimum igebe itheku valve kumelwe abe-okweshumi okubili a milimitha enephutha eliphelele elivumelekile ka kumakhulukhulu ezinhlanu ezingalawuleki milimitha. Futhi kwayo kuleyo ndawo yokuhweba kuba 0.35 mm. Lapho izikhala langempela akuzona efanele, khona-ke, usebenzisa idivayisi, udinga ukuthola puck, ngemva wehlise piston maphakathi phansi efile.

Ngaphezu kwalokho, ukushuba kunqunywa ezidingekayo ukufaka Washer. Kusukela Inani vymerennogo kumelwe sisuswe ukubaluleka igebe Kunconywa bese wengeza ukuba umphumela ubukhulu Washer. Zonke washers kukhona laser-kwasho enenani Uhlonze lwalo. Esimweni lapho, nganoma isiphi isizathu, nekukumakwa ibhekwa kabi, sebenzisa micrometer.

Okuthile lapho imvume umphini kumele imiswe ekushoneni elicacisiwe incwadi inkonzo yemoto.

Kamuva ngenkathi yezinguquko ngamunye crankshaft at eziyikhulu namashumi ayisishiyagalombili degrees kulinganiswa Inani lesikhala: yesihlanu nelesibili eyanele kanye qeda valve, owesithupha kanye qeda wesishiyagalombili eyanele, owesine lwesikhombisa ngokulandelana. Ngemva kokufaka washers usayizi edingekayo we usayizi igebe iyenziwa ngokuphindaphindiwe.

Ukulungisa backlashes ezishisayo of valve ezimotweni amazwe

ukufakwa esifike nobukhulu obufanele igebe kanye nesidingo injini yemoto yokungenisa abakhiqizi. Ngokuvamile, inqubo yokulungisa akuhlukile kangako kusukela idatha ebambe imisebenzi izinjini yasekhaya. Ngakho, ngokwesibonelo, emotweni "Honda" umphini nokusulwa Ungasetha kokwakhe, ngaphandle kosizo onguchwepheshe, ngenkathi kuphela usebenzisa ukufakwa kokumqoka kuphela kanye ukusonta. Njengoba i okuhlukile kungenzeka uma sibala ezingavamile powertrain nomkhiqizi ezimbalwa lapho kudingeka gidrokompensatsii uhlelo (S32A uhlobo izinjini). Ngamanye imishini uchungechunge ezihlukahlukene (V16-18-20; D13-14-15-16-17; R18-20; ZC nabanye) elungisa eyenziwa impela nje futhi ngaphandle kokusebenzisa imishini eyengeziwe kanye ezidingekayo.

Izikhala "Reno" ama-valve

Ngaphambi - imiyalelo eziningiliziwe esizikalayo ngokulungisa ama-valve yenjini, "Reno Logan".

Uyasikrufulula imishudo lemifanekiso air izindlu bese uyalikhipha. Ukuqaqa umlomo wombhobho valve ikhava. Broneprovoda ususa inhlansi plugs futhi bawasuse ngamunye ngamunye. Okulandelayo, uyasikrufulula imishudo ikhava valve , futhi ngobumnene uyisuse. Khona-ke, usebenzisa earphone, udinga hang out ngaphambili emotweni bese uvula igiya lesine. Ngokulandelayo, ukushintshanisa phambi isondo kuze F uphawu isondo camshaft. Kubalulekile ukuqapha uMbhalo umphini wokuqala. Ukusebenzisa ezishisayo Uphenyo isheke imvume, ngemva ziba ngcono isethi isikulufa Ilokhi nut. Uma igebe isethiwe, qinisa locknut nokuhlelwa kabusha thatha izilinganiso. Badlule ukulungisa we ilungu uMbhalo efanayo yesibili.

Ngaphezu kwalokho cranking le crankshaft isigamu ayaphenduka ulungise imvume umphini e uMbhalo lwesithathu. Ngokufanayo izakhi ukufakwa eyalo amasilinda wesine nelesibili.

Emva umsebenzi wenziwa ukulawula izilinganiso. Vula crankshaft ku degrees amathathu namashumi ayisithupha bese uhlole nokusulwa we valve.

Ngokwe-izici lobuchwepheshe yenjini, imithetho ukubeka abe nemingcele elandelayo:

• valve itheku - 0,1-0,15 mm.
• Ukuthweswa iziqu - 0.25-0.3 mm.

Endabeni esikhundleni ephelele valve qeda kukhona izikhala ekhethekile ethi awafike - 0.2-0.25 mm.

Kanjani ukuzivumelanisa injini ZMZ-402

Valve nokusulwa 402 motor efakwe mayelana efana nezinye izimoto.

Into yokuqala okudingeka ukupheqa ngokusebenzisa crankshaft clockwise ukusetha isilinda kuqala TDC (kokucindezelwa unhlangothi) futhi ukuqhathanisa amalebula isondo lokugijimisa indiphi elenzelwe into esindayo namakhava. Kulokhu, valve kumele ivalwe. Okokuqala, ubambe ukulungiswa we qeda. Kufanele kube lamashumi 0.35-0.4 mm. Eyanele umphini imvume kumelwe kuvumelane 0,4-0,45 mm. Ngemva ukusebenza uMbhalo ngowokuqala pass yesibili. Ungakhohlwa ukushintshanisa crankshaft lapho kugamanxa ukujika.

umsebenzi Ngaphezu kwalokho ne amasilinda yesithathu neyesine, pre-turning isikhathi ngasinye crankshaft.

Ekupheleni umsebenzi ezenziwe ukuqapha izilinganiso, uma kunesidingo, yenza ukulungiswa. Faka ikhava valve gasket futhi ikhava ngokwaso. Kulesi msebenzi, usuphethiwe.

yi

Lapho ethwele kahle imoto inqubo ukukhanda kuyoba injectivity ngaphezulu zinyamalale umsindo isici kusuka ikhava valve, bese wehlise petrol. Resource isikhathi kuzokhulisa kakhulu. Futhi, ukuze kugwemeke umonakalo ukusatshalaliswa igesi uhlelo izakhi ezidingekayo ukuqapha degree of ukungezwani idrayivu yibhande le camshaft. Kulokhu, amandla iyunithi izothatha isikhathi eside kakhulu kuneminyaka ihlandla lakhe.

Ngakho, thina esiphethweni indlela yokwenza ukulungiswa zabo umphini ku imoto.
