Kho li qub

Misaligned tsheb cav li qub Vaz-2101 tej zaum yuav ua rau kom muaj teeb txim. Ua ntej ntawm tag nrho cov, tsis tau txais ncaj qha rau tsav tsheb, uas yuav xav tias qhov kev nce nyob rau hauv roj noj, thiab tsis dynamic yam ntxwv ntawm lub tsheb. Tab sis, yog hais tias tag nrho cov ntsiab lus yog tsis yog tshwj xeeb tseem ceeb nyob rau hauv cov nyhuv cov kev mob ntawm lub cav, ceev ceev coj ntawm lub qub thiab tappets yuav ua tau kom ua hauj lwm ntawm lub sij hawm system. Kom tsis txhob no, kho valve yuav tsum muab qhov chaw nyob rau hauv ib tug raws sijhawm, raug thiab competently, li ntawd ua ntej pib cov coj hloov ua hauj lwm rau lub qub yuav tsum thawj kawm lub theoretical ib feem. Qhov no yuav tsum tau tham nyob rau hauv tsab xov xwm.

Yog li ntawd, ua ntej koj yuav tsum muaj txhua yam uas koj xav tau ntawm koj cov ntsis ntiv tes. Kho li qub tsis tau qhov chaw tsis muaj cuab yeej: set ntawm spanners thiab carob tuav ob peb screwdrivers, hloov hauv ob sab phlu nyob rau hauv lub valve cover, ib tug tseem ceeb rau cranking thiab tshwj xeeb sojntsuam 0.15 hli tuab. Tag nrho cov cuab yeej yuav tsum tau nyob rau hauv ib lub tsev rhiav. Nws tseem yog nqi kom paub los ntawm cov ntaub ntawv uas txoj kev kho valve, thiab yuav tsum tau ua twb zoo sau cov kev txiav txim nyob rau hauv ib daim ntawv ntawm daim ntawv los yog sau rau cov xov xwm.

Thiab tsis txhob hnov qab tias kho valve yog nqa tawm nyob rau hauv txias engine, raws li cov hlau expands thaum rhuab, thiab qhov no ua rau yus tsis raug.

Tam sim no peb mus ncaj qha mus rau lub haum. Tom qab tshem tawm ntawm lub valve cover ntawm lub engine, nws yog tsim nyog los crank lub crankshaft thiaj li mus rau coincide daim ntawv lo rau lub cev muaj zog tsev nyob nyob rau hauv pem hauv ntej ntawm (nyob rau cap) thiab lub camshaft sprocket. Los ntawm qhov kev txiav txim koj teem lub plaub lub tog raj kheej ntawm lub cav mus rau saum tuag center nyob rau hauv compression stroke. Raws li cov kev cov ntaub ntawv, kho valve yuav tsum tau nqa tawm nyob rau hauv lub tog raj kheej 3 thiab 4, namely №6 thiab №8 valve (count mus los ntawm pem hauv ntej sprocket). Koj yuav tsum mus sim thawb cov kev sojntsuam ntawm cov camshaft thiab cam. Yog hais tias tag nrho cov mus tau zoo thiab cov kev sojntsuam kis nruab nrab ntawm lawv nrog me ntsis kev rau siab, lub kawm tuab si lug ntawm lub valve lifters tsis tas yuav.

Yog hais tias cov kev sojntsuam kis dawb do, kiag li tsis muaj kev sib cuag nrog lub tsis sib haum xeeb chaw, los yog yog hais tias nws muaj peev xwm tsis lo nruab nrab ntawm lawv, nws yog tsim nyog los nqa tawm kev haum. Ib tug tseem ceeb mus rau lub "17" tso tus clamping noob txiv rau lub rocker valve-tswj, thiab tus yuam sij rau lub "13" yog screwed los yog unscrew laub pas nrig (yog hais tias tus sojntsuam yog chiv dhau dawb do, nws yog tsim nyog los ntswj thiab vice versa). Ntxiv mus, thaum lub yam tshwm sim yog tiav (cov kev sojntsuam no muaj nrog ib tug me ntsis sib koom tes, tab sis tsis khoov), koj yuav tsum tag nrho cov ceev thiab re-kos. Yog hais tias, tom qab xyuas txhua yam yog zoo, ces koj yuav siv npaj mus rau lub thib ob valve.

Kho valve muaj plaub theem cranking. Qhov saum toj no piav thawj theem, ua raws li los ntawm lub thib ob. Lub crankshaft yuav tsum muab los ntawm 180 degrees clockwise (yog, nws yog 180 degrees, yog li ntawd lub camshaft rotates tsuas muaj 90 degrees). Peb ua tib yam hauj lwm nrog cov cams nyob rau hauv №4 thiab №7, ces cranking lub crankshaft ntxiv 180 degrees thiab tswj lub 1 thiab thib 3 cam. Thaum kawg koj yuav tau tig lub crankshaft ib tug ntxiv 180 degrees thiab kho cov cams nyob rau hauv №5 thiab №2. Optionally, yog hais tias koj tsis tseeb heev ntawm lub correctness ntawm cov kev hloov, koj yuav rov hais dua cov tag nrho cov txheej txheem los ntawm thaum pib.

Yog li ntawd tam sim no koj paub tias dab tsi cov kev tswj valve, uas cov cuab yeej uas yuav tsum tau rau qhov no, thiab zoo li cas ib theem zuj zus ntawm cov txheej txheem. Tam sim no koj yuav tau mus xyuas ua ntej otkruchennye ceev rau cov rockers yuav tsum tau ntsia thiab cov valve cover. Pw nyob rau hauv nws hloov xwb thaum tsim nyog, yog li ntawd yog los ntawm nyob rau hauv nws tsis txhob nyem cov roj, koj yuav hloov tsis tau nws!
