Kugogoda modabwitsa kwa injini

Musanagule galimoto yogwiritsidwa ntchito, muyenera kusankha ngati mukufuna kusintha zonyamulira ma hydraulic valve. Tikachitapo kanthu mwamsanga, ndalamazo zidzakhala zochepa.

Magalimoto ogwiritsidwa ntchito nthawi zambiri amakhala ndi mtunda wopitilira makilomita 100. Km ndipo akukhulupirira kuti injini zawo zamafuta zimatha kupirira zambiri. Zowona, musanagule ndiyenera kusankha ngati ma hydraulic distributors ayenera kusinthidwa.  

Ngati titayankha mwamsanga, ndalama zidzakhala zochepa ndipo kunyalanyaza kungayambitse kukonzanso kwakukulu ndipo, mwatsoka, ndalama zambiri. Zonyamula ma valve za hydraulic kwambiri Ma injini amakono ambiri amagwiritsa ntchito zomwe zimatchedwa hydraulic valve lifters, zomwe zimapangitsa kuyendetsa galimoto kukhala kosavuta komanso kotchipa. "src="https://d.motofakty.pl/art/3w/vd/81cmzwg0koo0ww848kwo0/447151cadd95a-d.310.jpg" align="right"> ntchito zamagalimoto zotsogola. Ndikuthokoza kwa iwo kuti palibe chifukwa chosinthira nthawi ndi nthawi ma valve. Utumiki wamagalimoto ndiwofulumira komanso wotsika mtengo nthawi yomweyo. Pusher imayikidwa pakati pa camshaft ndi valve ndipo ntchito yake ndikukhazikitsanso sewero la valve chifukwa cha kuvala kwa magawo omwe akulumikizana.

Pusher durability

Mafuta a injini amayenda m'ma tappets motero amakhudzidwa kwambiri ndi mtundu wamafuta omwe amagwiritsidwa ntchito. Kusankha kolakwika kapena kolakwika kumatha kuwononga chinthu cholondola komanso chosalimbachi mwachangu kwambiri. Zofananazi zidzachitika ngati mipata pakati pa kusintha kwa mafuta ikuwonjezeka kwambiri. Moyo wautumiki wa pushers umasiyanasiyana, koma tingaganize kuti pafupifupi ndi 150 km. Zachidziwikire, sizodabwitsa kuti ma pushrods amagwira ntchito bwino ngakhale atathamanga 300 50. km, ndipo zimachitikanso kuti pambuyo pa XNUMX,XNUMX adzakhala ndi mwayi wolowa m'malo.

Momwe mungadziwire kuwonongeka?

Kuwonongeka kwa zonyamulira ma valve kungasonyezedwe ndi phokoso lochokera pafupi ndi chivundikiro cha valve. Uku ndikugogoda momveka bwino komanso kwachitsulo, mwachitsanzo, pakakhala chilolezo cha valve kwambiri. Mu gawo loyamba la kulephera kugwira ntchito, okankhira amapanga phokoso atangoyamba injini, ndiyeno amamveka nthawi zonse. Ngati phokosolo lizimiririka pamtunda wapamwamba, zikhoza kukhala chizindikiro chakuti kupanikizika mu dongosolo la mafuta ndilotsika kwambiri. Kusintha pushrod imodzi yokha kungakhale kopanda ntchito, chifukwa zimakhala zovuta kupeza zowonongeka (makamaka ngati ndi injini ya 16 valve). Ngati ma pushers ndi okwera mtengo, ndiye kuti atamvetsera mosamala injini, akhoza kusinthidwa, mwachitsanzo, pa silinda imodzi. Komabe, pamene ma pushrods sali okwera mtengo, ndi bwino kuwasintha onse mwakamodzi, chifukwa moyo wa enawo mwina ukutha. Mwanjira imeneyi, tidzapewa ndalama zogwirira ntchito mobwerezabwereza. Mtengo wosinthira umasiyanasiyana kwambiri ndipo zimatengera kumasuka kwa okankha komanso mtengo wa okankhira okha.

Phokoso la kuyendetsa nthawi siloyenera kulakwa kokha kwa okankha. Zitha kuyambitsidwanso ndi camshaft yovala kapena kutsika kwamafuta otsika komwe kumachitika, mwachitsanzo, ndi kusankha kolakwika kwamafuta (mafuta otsika kwambiri).

Amene amagwiritsa ntchito pushers

Makapu a Hydraulic amagwiritsidwa ntchito pamainjini ambiri masiku ano. Koma, ndithudi, pali zosiyana. Mwachizoloŵezi, Honda ndi Toyota sagwiritsa ntchito hydraulic regulation, ndipo VW yasintha kale ku malamulowa mu injini zonse, monga Opel, Mercedes, BMW ndi Daewoo (kupatula Tico ndi Matiza).

Ndizosiyana ndi injini zakale. Mayunitsi ambiri okhala ndi ma valve anayi pa silinda iliyonse amatha kusinthidwa ndi hydraulically. Kupatulapo ndi injini za Ford ndi Nissan, zomwe chilolezocho chimayendetsedwa ndi njira zachikhalidwe. Mu magalimoto French tingaganize kuti ngati injini ya petulo ndi awiri vavu, mipata kusintha pamanja, ndi zinayi vavu - hydraulically. Zomwezo zitha kuganiziridwa mu nkhawa ya Fiat, ngakhale nthawi zina zimakhala zosiyana.

Palibe ma hydraulic pushers

Kusintha pamanja valavu kukhomerera n'kosavuta ndipo nthawizina zonse zomwe mukusowa ndi feeler gauge, muyezo wrench ndi screwdriver. Komano, m'mainjini ambiri, kukonza chilolezo ndizovuta, zowononga nthawi (mpaka maola 8) komanso ntchito yodula ndikuchotsa lamba wanthawi ndi ma shaft ndikusintha zinthu zina. Mtengo wa kusinthaku umachokera ku 30 mpaka 500 PLN, kutengera kuchuluka kwa zovuta. Kuchuluka kwa kusintha kwa backlash kumasiyana 10 mpaka 100 zikwi. km. Pankhani ya refueling ndi gasi, tikulimbikitsidwa kuyang'ana mmbuyo pafupipafupi, chifukwa mumainjini ambiri agasi kubweza kumachepa mwachangu. Ndipo kusowa kwa masewera kumayambitsa kutaya mphamvu, komanso kungawononge kwambiri injini.
