Chivundikiro cha zida zogwiritsira ntchito nthawi ya galimoto.
Magiya owerengera nthawi amayikidwa mu makina olowetsa ndi otulutsa mpweya m'mainjini oyatsa mkati, m'mawotchi ndi machitidwe ena am'deralo omwe ali ndi ubale wotsatizana ndi ntchito zonse zamakina.
Njira zitatu zotumizira giya: kuyendetsa unyolo, kuyendetsa lamba wa mano, kuyendetsa giya.
Magiya abwino ndi oipa a injini ya galimoto amayendetsedwa ndi lamba wa mano, womwe uli ndi ubwino wa kapangidwe kosavuta, phokoso lochepa, ntchito yosalala, kulondola kwambiri kwa kutumiza, kulumikizana bwino, ndi zina zotero, koma mphamvu yake ndi yochepa, ndipo ndi yosavuta kukalamba, kutambasula kusintha kapena kusweka pambuyo pa kugwiritsidwa ntchito kwa nthawi yayitali. Lamba wa mano ali mu mkhalidwe wotsekedwa mu chivundikiro chakunja, zomwe zimakhala zovuta kuwona momwe akugwirira ntchito. Pali galimoto ya Mitsubishi, palibe zizindikiro zoyambira, pambuyo pa mafuta, kufufuza kwa dera, cholakwika chikadalipo, kenako ndikutsegula chivundikiro cha chipinda cha valve, ndikupeza kuti mkono wa valve rocker sukugwira ntchito, ndikupeza kuti lamba wa nthawi ya dzino wasweka. Pambuyo posintha chinthu chatsopano, injiniyo siyambabe. Chifukwa, lamba wa mano akasweka akugwira ntchito, camshaft imasiya kugwira ntchito, ndipo crankshaft ipitiliza kuzungulira ngodya inayake kapena kuchuluka kwa ma turns pansi pa kuchita kwa inertia yozungulira ya flywheel kapena inertia ya chipangizo chotumizira. Panthawiyi, injini siigwira ntchito, ndipo chofunika kwambiri, gawo la valavu limawonongeka, ndipo pisitoni idzapinda ndodo ya valavu pamwamba pamalo otseguka, zomwe zimapangitsa kuti valavu itsekedwe mosasamala. Chifukwa chake, mainjini ena okhala ndi malamba osweka a mano, ngakhale chizindikiro cha giya la nthawi chikakonzedwanso, ndipo lamba watsopano wa nthawi wasinthidwa, injiniyo imakhala yovuta kuyambitsa, kapena yolephera kuyamba, koma ntchitoyo si yachilendo, ndipo chodabwitsa cha "kutenthetsa", "kuwombera", mphamvu yosakwanira, ndi phokoso lowonjezeka zimachitika. Pankhaniyi, pochotsa mutu wa silinda ndikuyikanso valavu ndiye kuti mkhalidwe waukadaulo wa injini ungabwezeretsedwe kwathunthu. Nthawi ndi momwe valavu imagwirira ntchito ziyenera kugwirizana ndi momwe valavu imagwirira ntchito komanso nthawi ya kayendedwe ka pisitoni, ndipo crankshaft ndi camshaft sizili pa axis, ziyenera kulumikizidwa ndi makina otumizira, makina otumizira amadzazidwa ndi magiya awiri ndi unyolo kapena lamba, kenako magiya awiriwa amatchedwa timing gear, magiya awiriwa amalembedwa chizindikiro. Pambuyo poyika unyolo kapena lamba molingana ndi chizindikirocho, imatha kutsimikizira kuti nthawi ndi momwe valve imagwirira ntchito ndi yolondola.
Ntchito ya chivundikiro cha zida zogwiritsira ntchito nthawi ndikuteteza zida zogwiritsira ntchito nthawi ku fumbi ndi madzi. Ntchito ya zida zogwiritsira ntchito nthawi ndikuyika muyeso wa nthawi yokwanira kuti ntchito zowongolera zoyenera zitheke mu chipangizo cha makina zithe.
Giya yogwiritsira ntchito nthawi ndi giya yomwe imagwira ntchito yowerengera nthawi kuti ikwaniritse ntchito zoyenera zowongolera mu chipangizo chamakina. Giya yogwiritsira ntchito nthawi imayikidwa mu makina olowetsa ndi otulutsa mpweya m'mainjini oyatsa mkati, m'mawotchi ndi machitidwe ena am'deralo omwe ali ndi ubale wotsatizana ndi ntchito zonse zamakina.
Udindo wa zida zowerengera nthawi: zimatha kusewera gawo loyika nthawi pomaliza ntchito zowongolera zoyenera mu chipangizo chamakina.
Njira zitatu zotumizira giya nthawi: kuyendetsa unyolo, kuyendetsa lamba wa mano, kuyendetsa giya. Magiya abwino ndi oipa a injini ya galimoto amayendetsedwa ndi lamba wa mano, omwe ali ndi ubwino wa kapangidwe kosavuta, phokoso lochepa, kugwira ntchito bwino, kulondola kwa magiya apamwamba, kulumikizana bwino, ndi zina zotero, koma mphamvu yake ndi yochepa, yosavuta kukalamba, kusinthasintha kwa magiya kapena kusweka pambuyo pogwiritsidwa ntchito kwa nthawi yayitali, ndipo ndizosavuta kuwona momwe imagwirira ntchito.
Nthawi ndi momwe valavu imagwirira ntchito ziyenera kugwirizana ndi momwe pisitoni imagwirira ntchito, ndipo crankshaft ndi camshaft sizili pa axis, ndipo payenera kukhala njira yotumizira pakati pawo kuti zilumikizane, njira yotumizira imadzazidwa ndi magiya awiri ndi unyolo kapena lamba, kenako magiya awiriwa amatchedwa magiya oti timing.
Kulephera kwa zida za injini ya galimoto
Injini ikagwira ntchito, imapanga phokoso losalekeza kapena losinthasintha kutsogolo kwa injini. Muzochitika zachizolowezi, liwiro likakwera, phokoso limakulanso; Phokoso silisintha kutentha kukasintha; Phokoso la moto wosweka wa silinda imodzi silichepa.
Zifukwa zomwe zingayambitse phokoso losazolowereka la zida zogwiritsira ntchito nthawi
(1) Mpata wa kuphatikiza kwa zida ndi waukulu kwambiri kapena wochepa kwambiri
(2) Mtunda wapakati pakati pa dzenje lalikulu la crankshaft ndi dzenje lothandizira camshaft umasintha panthawi yogwiritsidwa ntchito kapena kukonza, ndipo umakhala waukulu kapena wocheperako; Mizere yapakati ya crankshaft ndi camshaft siili yofanana, zomwe zimapangitsa kuti magiya asagwirizane bwino.
(3) Kapangidwe ka dzino la giya sikukonzedwa, kusintha kwa kutentha kapena pamwamba pa dzino lawonongeka kwambiri;
(4) Mpata woluma suli wolimba kapena kudula mizu kumachitika panthawi yozungulira zida;
(5) pamwamba pa dzino pali zipsera, ming'alu kapena kusweka kwa dzino;
(6) Giyayo ndi yomasuka kapena yatuluka pa crankshaft kapena camshaft;
(7) mawonekedwe a giya ozungulira kapena ozungulira ndi akulu kwambiri;
(8) crankshaft kapena camshaft axial clearance ndi yayikulu kwambiri;
(9) Magiya sasinthidwa awiriawiri.
(10) Mukasintha crankshaft ndi camshaft bearing bush, malo olumikizira magiya amasinthidwa.
(11) chogwirira ntchito cha camshaft nthawi yokonza nati chimasuka.
(12) camshaft timing gear kutayika kwa dzino, kapena kuphulika kwa radial ya gear.
Zida zogwiritsira ntchito nthawi zomwe sizigwira ntchito bwino
1) Phokoso lake ndi lovuta kwambiri, nthawi zina limamveka ngati nyimbo, nthawi zina silimveka ngati nyimbo, nthawi zina limamveka ngati liwu losasinthasintha, nthawi zina limamveka ngati liwu lopitirira.
2) Injini ikasiya kugwira ntchito kapena liwiro likasintha, pamakhala phokoso losokonezeka komanso laling'ono pachivundikiro cha chipinda cha giya panthawi yogwiritsira ntchito, ndipo phokosolo limasowa liwiro litawonjezeka, ndipo phokoso limawonekera injini ikachepa mofulumira.
3) Ma sound ena sakhudzidwa ndi kutentha ndi mayeso a single silinda yozimitsa moto, ndipo ena amakhudzidwa ndi kutentha, palibe phokoso kutentha kuli kochepa, ndipo kutentha kukakwera kufika pamlingo wabwinobwino, phokoso limawonekera.
4) Ma sound ena amatsagana ndi kugwedezeka kwa chivundikiro cha chipinda cha giya yokhazikika, ndipo ena satsagana ndi kugwedezeka.
