Vim li cas lub valve khoov thaum lub sij hawm siv txoj hlua tawg?
Lub valve mechanism ua haujlwm raws li hauv qab no: thaum lub piston nce mus txog qhov chaw tuag saum toj kawg nkaus, ob lub li qub nyob rau hauv lub combustion chamber kaw thiab ib qho kev siab yog tsim nyob rau hauv nws. Txoj siv tawv tawg coj mus rau qhov tseeb tias valve lawv tsis muaj sijhawm los kaw lub sijhawm ua ntej lub piston tuaj txog. Yog li, lawv lub rooj sib tham tshwm - kev sib tsoo, uas ua rau muaj tseeb tias lub valve khoov. Yav dhau los, txhawm rau tiv thaiv cov teeb meem zoo li no, cov grooves tshwj xeeb tau tsim rau cov li qub ntawm cov qub combustion xyaw. Ntawm cov tshuab hluav taws xob tshiab sab hauv combustion, qhov zoo sib xws kuj tseem pom, tab sis lawv tsuas yog npaj kom tsis txhob deformation ntawm lub li qub thaum lub sijhawm ua haujlwm ntawm lub tshuab hluav taws xob sab hauv thiab, thaum muaj kev sib tsoo, lawv tsis pab kiag li.
Los ntawm qhov pom ntawm lub cev, txij li lub sijhawm siv lub sijhawm so, lub camshafts nres tam sim ntawd, nyob rau hauv qhov kev txiav txim ntawm rov qab springs uas nres nws cov cams. Lub sijhawm no, lub crankshaft inertially tseem tig mus (tsis hais seb lub iav puas tau koom nrog lossis tsis, txawm tias qhov ceev qis lossis siab, lub flywheel tseem tig nws). Ntawd yog, cov pistons txuas ntxiv ua haujlwm, thiab yog li ntawd, lawv tsoo lub li qub uas qhib rau lub sijhawm ntawd. Tsis tshua muaj, tab sis nws tshwm sim thaum lub li qub ua rau lub piston nws tus kheej.
Ua rau lub sijhawm siv lub sijhawm tawg
- hnav ntawm nws tus kheej los yog nws cov khoom tsis zoo (shaft gears muaj cov npoo ntse lossis roj los ntawm cov ntsaws ruaj ruaj).
- crankshaft jams.
- twj tso kua mis (qhov tshwm sim feem ntau).
- ob peb los yog ib lub camshaft jams (piv txwv li, vim yog ib qho ntawm lawv ua tsis siv tau - txawm li cas los xij, qhov tshwm sim ntawm no txawv me ntsis).
- Lub nro cov menyuam unscrews los yog lub rollers jam (cov siv yuav xoob los yog overtightened).
Niaj hnub nimno cav, txij li thaum lawv muaj zog dua piv rau lawv cov predecessors, muaj ntau tsawg survivability. Yog tias peb xav txog qhov ua rau raws li cov li qub, qhov teeb meem no tshwm sim vim qhov deb me me ntawm lawv thiab lub piston. Ntawd yog, yog tias lub sijhawm lub piston tuaj txog lub valve qhib me ntsis, ces nws tam sim ntawd khoov. Txij li thaum rau ntau dua compression thiab contraction nyob rau hauv qab ntawm lub piston yog tsis muaj zawj rau lub valve ntawm qhov xav tau qhov tob.
Nyob rau hauv uas combustion engines ua li qub khoov?
Nyob rau hauv lub tsheb nrog 8-valve combustion engine, khoov tshwm sim tsawg kawg nkaus, tab sis nrog 16 thiab 20 li qub, nws yog roj av los yog diesel, khoov tshwm sim nyob rau hauv feem ntau. Muaj tseeb, qee zaum nws tuaj yeem yog ib lossis ntau lub li qub, thiab yog tias lub tshuab hluav taws xob sab hauv yog idling, ces teeb meem yuav tuaj. Tab sis muaj qee qhov xwm txheej zoo li no, feem ntau yog qhov tshwm sim tsis tuaj yeem rov qab los. Ib lub rooj nrog cov npe ntawm cov tshuab hluav taws xob sab hauv uas cov li qub ntawm txhua lub tsheb nrov khoov thaum lub sij hawm siv txoj hlua tawg.

Yuav ua li cas koj thiaj paub yog tias lub valve yog khoov?
Tshawb xyuas lub tshuab hluav taws xob sab hauv kom pom tias cov li qub puas muaj kev pheej hmoo ntawm kev khoov tom qab lub sijhawm siv sijhawm so
Tsis yog ib qho kev kuaj pom lossis cov lej muab rau hauv cov lus "valve bend" yuav pab tau koj hauv qhov teeb meem no. Txawm hais tias koj muaj cov ntaub ntawv los ntawm cov chaw tsim khoom txog kev puas tsuaj nyob rau hauv qhov xwm txheej ntawm txoj siv tawv tawg, nws tsis paub tias nws yog qhov tseeb npaum li cas.
Yog tias koj xav kuaj xyuas qhov ua tau ntawm lub valve piston dabtsi yog khoov thaum lub sijhawm siv txoj siv sia tawg, koj yuav tsum tshem txoj siv, teeb tsa thawj lub piston ntawm TDC, thiab tig lub camshaft 720 degrees.
Yog tias txhua yam mus zoo thiab nws tsis tau daig, koj tuaj yeem sim txuas ntxiv - txav mus rau lub piston thib ob. Thaum txhua yam zoo nyob ntawd, tom qab ntawd txoj siv sia tuaj yeem tawg yuav tsis ua rau muaj qhov tsis zoo rau lub tshuab hluav taws xob sab hauv ntawm koj lub tsheb.
Txhawm rau zam qhov teeb meem no (khoov li qub thaum tawg), koj yuav tsum tau saib xyuas qhov xwm txheej thiab nruj ntawm txoj siv sijhawm. Yog tias lub suab nrov me ntsis uas tsis paub meej tshwm sim thaum lub sijhawm ua haujlwm, koj yuav tsum sim tam sim kom paub qhov ua rau nws tshwm sim thiab tshuaj xyuas qhov xwm txheej ntawm cov rollers thiab lub twj tso kua mis.
Thaum yuav ib lub tsheb siv, hloov lub sij hawm siv tam sim ntawd, tsis hais tus neeg muag khoom qhia li cas. Thiab ces xws li ib tug nias nug li Puas yog valve khoov thaum tawg? Nws yuav tsis thab koj.
Bent valve kos npe
Thaum txoj siv sia tawg, tsuas yog hloov txoj siv lub sijhawm, cia siab tias txhua yam mus yam tsis muaj qhov tshwm sim thiab koj yuav pib lub cav, tsis tsim nyog. Tshwj xeeb tshaj yog yog hais tias lub internal combustion engine yog nyob rau hauv cov npe ntawm cov uas lub li qub khoov. Yog lawm, muaj qee zaus thaum khoov tsis loj thiab ob peb lub li qub tsis haum nruj rau hauv lub rooj zaum, ces koj tuaj yeem tig nws nrog lub oob khab, tab sis feem ntau cov kev ua no yuav ua rau qhov xwm txheej tsis zoo. Txij li thaum muaj kev puas tsuaj me me txhua yam yuav ua haujlwm thiab tig, tab sis lub tshuab hluav taws xob sab hauv yuav co co, thiab qhov tshwm sim yuav tsuas yog phem dua.
Nws yog qhov zoo tshaj yog tias koj tshem tawm "lub taub hau" txhawm rau txhawm rau txheeb xyuas qhov pom lossis sau nws nrog roj av, txawm li cas los xij, muaj ntau txoj hauv kev los xyuas seb lub valve puas khoov yam tsis muaj kev cuam tshuam lub tshuab hluav taws xob sab hauv.
Cov tsos mob tseem ceeb yog hais tias cov li qub yog khoov - me me los yog tag nrho tsis muaj compression. Yog li ntawd, koj yuav tsum ntsuas qhov compression hauv lub tog raj kheej. Tab sis, cov kev ua no cuam tshuam yog tias lub crankshaft tuaj yeem tig thiab tsis muaj dab tsi nyob qhov twg. Yog li thawj qhov koj yuav tsum tau ua yog nruab ib txoj siv tshiab, manually, siv lub ntsia liaj qhov rooj ntawm CV, tig tag nrho cov roj faib tshuab ob peb lem (koj yuav tsum tau unscrew lub txim plugs).
Yuav ua li cas xyuas yog tias lub valve yog khoov
Txhawm rau txiav txim siab seb puas muaj lub qia valve yog khoov, txhais tau tsib zaug ntawm tes tig lub crankshaft ntsia liaj qhov rooj nrog lub ciaj ntswj yuav txaus. Yog tias cov pas nrig tsis zoo, qhov kev sib hloov yuav dawb; yog tias cov pas nrig yog khoov, qhov kev sib hloov yuav hnyav. Tseem yuav tsum tau pom meej meej 4 cov ntsiab lus (nrog ib lub kiv puag ncig) ntawm kev tiv thaiv rau kev txav ntawm lub pistons. Yog tias qhov kev tiv thaiv tsis pom zoo, ces ntsia hlau lub taub hau rov qab rau hauv, unscrew lawv ib qho los ntawm ib qho thiab tig lub crankshaft dua.
Raws li phau ntawv torsion quab yuam, nrog ib qho ntawm lub txim plugs ploj lawm, nws yog qhov yooj yim to taub nyob rau hauv qhov tshwj xeeb lub tog raj kheej lub valve tau khoov. Txawm li cas los xij, txoj kev no yuav tsis tas yuav pab txiav txim siab seb lub valve yog khoov los yog tsis.
Yog hais tias lub crankshaft rotates dawb, ces koj ua tau check nrog compression gauge. Tsis muaj cov cuab yeej zoo li no? txhais tau tias ua ib qho kev sim pneumatic, thiab xyuas qhov nruj ntawm lub tog raj kheej yog txoj hauv kev zoo tshaj plaws, uas yuav muab cov lus teb rau yuav ua li cas lub valve daim hlau haum rau hauv lub rooj zaum, tsis muaj qhov tshwm sim ntxiv thaum cranking nrog lub oob khab thiab tsis txhim kho txoj siv tshiab.
Yuav ua li cas xyuas seb lub valve yog khoov koj tus kheej li cas?
Rau kev sim pneumatic, koj tsis tas yuav nqa lub tsheb mus rau qhov chaw pabcuam; koj tuaj yeem paub koj tus kheej seb lub tog raj kheej kaw lossis tsis. Txoj kev yooj yim tshaj plaws yog:
- xaiv ib daig ntawm hose raws li txoj kab uas hla ntawm lub txim plug zoo;
- unscrew lub tswm ciab;
- teem lub tog raj kheej piston rau saum qhov chaw tuag (valve kaw) ib zaug;
- ntxig lub hose nruj nreem rau hauv qhov dej;
- Sim nrog tag nrho koj lub peev xwm los tshuab rau hauv chav combustion (cua dhau los - nws yog khoov, tsis dhau - "tshuab ploj").
Tib qhov kev sim tuaj yeem ua tau siv lub tshuab compressor (txawm tias lub tshuab ib qho). Muaj tseeb, koj yuav tau siv sijhawm me ntsis ntxiv, raws li koj yuav tsum tau npaj. Laum tawm lub hauv paus electrode nyob rau hauv lub qub spark plug, thiab muab ib tug hose ntawm lub ceramic tip (kho nws zoo nrog ib tug clamp). Tom qab ntawd tso siab rau hauv lub tog raj kheej (muab tias lub piston hauv nws yog nyob ntawm TDC).
Lub suab nrov thiab lub siab ntawm lub ntsuas siab yuav qhia koj seb lub kaus mom valve puas zaum lossis tsis. Ntxiv mus, nyob ntawm seb huab cua mus qhov twg, txiav txim siab qhov inlet bent lossis tso pa tawm. Thaum lub qhov hluav taws xob tso tawm yog khoov, cua nkag mus rau hauv lub qhov tso pa tawm (muffler). Yog hais tias lub intake valve yog khoov, ces mus rau hauv lub intake tract.
