Kodi mafuta a injini ya timing ndi chiyani? Ichi ndi chifukwa chenicheni cha vutoli.
Anthu omwe akhala ndi vuto ndi kutambasula kwa nthawi yayitali mwina amva kapena kuwerenga kwinakwake kuti akugwirizana ndi kusintha mafuta a injini. Ngati amvetsetsa makaniko, akudziwa kuti si nkhani yodzipaka mafuta okha. Nanga n’cifukwa ciani?
M'mbuyomu, unyolo wanthawi yayitali unali wamphamvu kwambiri kotero kuti zinali zosatheka kusintha. Zabwino kwambiri, pokonza injini yayikulu. Masiku ano ndi mapangidwe osiyana kotheratu. Mu injini zamakono, maunyolo ndi otalika kwambiri ndipo amatambasulidwa pakati pa magiya angapo.. Komanso, iwo ali kutali ndi mzake, chifukwa camshafts ili mu fuselage, i.e. pafupi ndi crankshaft, mbiri yakale.
Zonsezi zikutanthauza kuti unyolo uyenera kukhazikika bwino osati pa sprockets, komanso pakati pawo. Udindo uwu umachitidwa ndi mitundu iwiri ya zinthu - otchedwa otsogolera ndi tensioners. Ma skids amakhazikika unyolo ndikuwukakamiza m'malo omwe mawilo amakangana., ndi ma tensioners (nthawi zambiri tensioner imodzi - yolembedwa ndi muvi wofiira pa chithunzi) sungani unyolo wonse pamalo amodzi kupyolera mu nsapato imodzi (pa chithunzichi wotsutsa amapondereza pa slider).
The timing chain tensioner ndi gawo losavuta la hydraulic. (ngati makina, ndiye musawerenge mopitilira, nkhaniyi ikunena za hydraulic). Zimagwira ntchito zokha kutengera mphamvu yamafuta yomwe imapangidwa m'dongosolo. Kuthamanga kwapamwamba, mphamvu yowonjezera, yapansi, yocheperapo. Unyolo uyenera kumangika, mwachitsanzo, pamene katundu pa injini akuwonjezeka, komanso pamene unyolo kapena zinthu zina zavala. The tensioner ndiye amalipira kuvala pa zigawo za nthawi. Pali nsomba imodzi - imayendera mafuta omwewo omwe amapaka injini.
Mafuta amafunikira mafuta abwino.
Mafuta a injini omwe amalowa m'malo otsekemera pa gawo loyamba la ntchito, atangoyamba injini, amakhala wandiweyani komanso ozizira. Ilibe kutentha koyenera panobe, kotero simayendanso. Patapita kanthawi, pamene ikuwotha, imagwira ntchito yake 100 peresenti. Komabe, ndikugwiritsa ntchito mafuta ndi kuipitsidwa, nthawi yoyambira ndikugwira ntchito moyenera kwamafuta, chifukwa chake kupsinjika kumawonjezeka. Zimatalika kwambiri mukathira mafuta a viscous kwambiri mu injini. Kapena mumasintha pafupipafupi.
Tinafika pamtima pa vutolo. Wolakwika tensioner Izi sizimangopangitsa kuti unyolo ukhale womasuka kwambiri mumphindi zoyambirira kapena maminiti oyambirira a ntchito, komanso pamene mafuta ali "wokhuthala" kapena odetsedwa, wothamanga samayankha bwino. Zotsatira zake, unyolo wokhazikika wokhazikika molakwika umawononga zinthu zomwe zimagwirizana (zoyenda, magiya). Ndizoipa kwambiri mafuta akuda sangafike pa tensioner yakuda kale ndipo iyi sigwira ntchito konse (kusintha voteji). Kukwera kovala kwa zinthu zokwerera, kusewera kwambiri, unyolo umatha kwambiri mpaka titafika pomwe mukumva ...
unyolo chophimba
Ndizosatheka kuyang'ana momwe ma chain chain drive alili mwanjira iliyonse yosasokoneza popanda kugwetsa nyumba yonse ndikuwunika zigawo zake. Mosiyana ndi maonekedwe, ili ndi vuto lalikulu, koma zambiri pambuyo pake. Chofunika kwambiri, phokoso lomwe limachokera ku nthawi, zomwe sizimatengedwa nthawi zonse ndi makina, osagula galimoto yogwiritsidwa ntchito, ndi chizindikiro cha kuvala pa nthawi yoyendetsa galimoto. Palibe phokoso, kupatulapo unyolo wanthawi yotayirira. Kuyankha mwachangu kwa wogwiritsa ntchito, kumachepetsanso ndalama zomwe zingatheke. M'mainjini ambiri, ndikwanira m'malo mwa tensioner ndi unyolo, mwa ena seti yathunthu ya sleds, ndipo chachitatu, muzovala kwambiri, magiya amafunikabe kusinthidwa. Ndizovuta kwambiri ngati magiya ali ndi nthawi yosinthika ya valve. Izi zikutanthauza kale ndalama mu masauzande a PLN pazigawo zosinthira.
Izi ndizovuta kwambiri Nthawi zambiri injini zama unyolo ndi injini zabwino. Komabe, ndizosatheka kuyang'ana malowa popanda kukhudzidwa ndi makaniko ndi msonkhano. Chitsanzo ndi Audi, BMW kapena Mercedes dizilo zolimba kwambiri. Ngati zonse zili zachilendo, ndiye kuti ndizochepa, zamphamvu komanso zachuma. Komabe, mutagula galimoto ndi unyolo wotambasulidwa, koma, mwachitsanzo, osamveka phokoso, zikhoza kukhala kuti kuti musangalale ndi zabwino zonse za injini ya dizilo, muyenera kugwiritsa ntchito PLN 3000-10000 pa lamba wa nthawi. m'malo. .
