Mysterious cav khob
Ua ntej yuav ib lub tsheb siv, koj yuav tsum txiav txim siab seb koj puas yuav tsum tau hloov cov hydraulic valve lifters. Yog tias peb teb sai sai, cov nqi yuav tsawg.
Cov tsheb siv feem ntau muaj ib mais deb ntawm ntau tshaj 100 kilometers. km thiab ntseeg tias lawv cov roj av cav tuaj yeem tiv taus ntau dua. Muaj tseeb, ua ntej yuav khoom nws tsim nyog txiav txim siab seb puas yuav tsum tau hloov cov hydraulic distributors.
Yog tias peb teb sai sai, cov nqi yuav tsawg thiab kev tsis saib xyuas tuaj yeem ua rau kev kho loj thiab, hmoov tsis, cov nqi siab. Hydraulic valve lifters ho ntau ntau lub cav niaj hnub siv lub npe hu ua hydraulic valve lifters, uas ua rau lub tsheb khiav yooj yim dua thiab pheej yig dua. " src="https://d.motofakty.pl/art/3w/vd/81cmzwg0koo0ww848kwo0/447151cadd95a-d.310.jpg" align="right"> Kev pabcuam tsheb zoo dua. Nws yog ua tsaug rau lawv tias tsis tas yuav tsum tau kho lub valve clearances ib ntus. Kev pabcuam tsheb nrawm dua thiab pheej yig dua tib lub sijhawm. Lub pusher yog ntsia nruab nrab ntawm lub camshaft thiab lub valve thiab nws txoj hauj lwm yog los pib dua lub valve ua si uas tshwm sim los ntawm hnav ntawm interacting qhov chaw.
Pusher durability
Cav roj ntws los ntawm tappets thiab yog li ntawd rhiab heev rau qhov zoo ntawm cov roj siv. Cov khoom tsis zoo lossis kev xaiv tsis raug tuaj yeem ua rau cov ntsiab lus meej thiab muag heev sai sai. Ib qho xwm txheej zoo sib xws yuav tshwm sim yog tias qhov sib txawv ntawm cov roj hloov pauv tau nce ntxiv. Lub neej kev pabcuam ntawm cov neeg thawb sib txawv, tab sis nws tuaj yeem xav tias qhov nruab nrab nws yog li 150 km. Tau kawg, nws tsis yog qhov tsis yooj yim uas cov pushrods ua haujlwm zoo txawm tias tom qab khiav ntawm 300 50. km, thiab nws kuj tshwm sim tias tom qab XNUMX txhiab yuav muaj cai hloov pauv.
Yuav ua li cas thiaj paub kev puas tsuaj?
Kev puas tsuaj rau lub valve lifters tej zaum yuav qhia tau los ntawm lub suab nrov los ntawm ze lub valve cover. Qhov no yog qhov tseeb thiab yog xim hlau khob, piv txwv li, nyob rau hauv cov ntaub ntawv ntawm ntau dhau valve clearance. Nyob rau hauv thawj theem ntawm lub malfunction, lub pushers ua suab nrov tsuas yog sai tom qab pib lub cav, thiab ces lawv hnov tsis tu ncua. Yog tias lub suab nrov ploj ntawm qhov siab dua rpm, nws yuav yog ib qho kev qhia tias lub siab hauv lub tshuab lubrication qis dhau. Hloov ib lub laub tsuas tuaj yeem ua tsis tau zoo, vim nws nyuaj heev los nrhiav qhov puas tsuaj (tshwj xeeb tshaj yog tias nws yog lub cav 16-valve). Yog tias cov pushers kim, tom qab ua tib zoo mloog lub cav, lawv tsuas yog hloov tau, piv txwv li, ntawm ib lub tog raj kheej. Txawm li cas los xij, thaum lub pushrods tsis kim, nws tsim nyog hloov lawv txhua lub sijhawm, vim tias lub neej ntawm tus so yog zaum kawg. Nyob rau hauv txoj kev no, peb yuav zam tsis tsim nyog cov nqi zog ua haujlwm. Tus nqi hloov pauv txawv heev thiab nyob ntawm qhov yooj yim ntawm kev nkag mus rau cov pushers thiab tus nqi ntawm cov pushers lawv tus kheej.
Lub suab nrov ntawm lub sijhawm tsav tsheb tsis yog tsuas yog liam rau cov pushers. Nws kuj tuaj yeem tshwm sim los ntawm kev hnav lub camshaft lossis cov roj qis uas tshwm sim, piv txwv li, los ntawm kev xaiv cov roj lim tsis raug (roj noj tsawg dhau).
Leej twg siv pushers
Hydraulic tappets yog siv rau feem coob ntawm cov cav niaj hnub no. Tab sis, ntawm chav kawm, muaj kev zam. Kev lig kev cai, Honda thiab Toyota tsis siv hydraulic tswj, thiab VW tau ntev txij li hloov mus rau cov kev cai no hauv txhua lub cav, xws li Opel, Mercedes, BMW thiab Daewoo (tshwj tsis yog Tico thiab Matiza).
Nws txawv nrog cov cav qub. Feem ntau ntawm cov chav nyob nrog plaub li qub rau ib lub tog raj kheej yog hydraulically adjustable. Qhov kev zam yog qee qhov Ford thiab Nissan cav, uas qhov kev tshem tawm yog tswj hwm los ntawm cov txheej txheem ib txwm muaj. Hauv Fabkis cov tsheb, nws tuaj yeem xav tias yog lub cav roj av yog ob-valve, ces qhov khoob yog kho manually, thiab plaub-valve - hydraulically. Tib yam tuaj yeem xav tau hauv Fiat kev txhawj xeeb, txawm hais tias qee qhov nws txawv.
Tsis muaj hydraulic pushers
Manually kho valve nailing yog ib qho yooj yim thiab qee zaum txhua yam koj xav tau yog lub ntsuas ntsuas ntsuas, tus qauv ciaj ntswj thiab lub hau ntswj. Ntawm qhov tod tes, nyob rau hauv ntau lub cav, kev kho qhov kev tshem tawm yog qhov hnyav, siv sijhawm ntev (txog 8 teev) thiab kev ua haujlwm kim nrog kev tshem tawm ntawm lub sijhawm siv thiab shafts thiab hloov qee cov ntsiab lus. Tus nqi ntawm qhov kev hloov pauv yog los ntawm 30 txog 500 PLN, nyob ntawm seb qhov kev ua haujlwm nyuaj. Qhov zaus ntawm kev hloov kho backlash txawv ntawm 10 mus rau 100 txhiab. km. Nyob rau hauv cov ntaub ntawv ntawm refueling nrog roj, nws yog pom zoo kom mus xyuas lub backlash ntau zaus, vim hais tias nyob rau hauv ntau lub cav roj, lub backlash poob sai heev. Thiab qhov tsis muaj kev ua si ua rau poob ntawm lub zog, thiab tuaj yeem ua rau lub cav loj heev.
