Injini ikugogoda pozizira mu Polo Sedan

Mu kusintha kwa "Polo Sedan", eni ake nthawi zambiri amakumana ndi kuzizira kwa injini.

Zifukwa za kugunda kwa injini ya Polo sedan

Injini yosinthidwa bwino yokhala ndi mafuta okwanira imayenda bwino komanso popanda kusokoneza. Madalaivala odziwa bwino amatchula izi ngati "kunong'ona". Kugogoda kumawoneka ngati mawu a episodic, achidule, osamveka omwe amaphwanya chithunzi chonse. Malinga ndi momwe zimakhudzira, ma echoes ake ndi malo, ma wipers amazindikiranso chomwe chimayambitsa kusagwira ntchito.

Sedan ya VW Polo ndi yosiyana chifukwa pamtunduwu, ogwiritsa ntchito nthawi zambiri amakumana ndi vuto ngati injini imagogoda pakazizira. Mukayamba injini mutayima, kugwedezeka kwakanthawi kochepa kapena kugwedezeka kumawonedwa.

Pambuyo pogwira ntchito kwa nthawi inayake (nthawi zambiri kuyambira masekondi makumi awiri mpaka makumi atatu mpaka mphindi imodzi ndi theka mpaka mphindi ziwiri), kugunda kumachepa kapena kutha.

Zina mwazomwe zimayambitsa kugogoda mu injini yozizira ndi izi:

1. Kugwiritsa ntchito molakwika zonyamula ma hydraulic. Ngakhale node iliyonse ili ndi zida zake, ngakhale zonyamula ma hydraulic zatsopano sizingagwire ntchito bwino. Chifukwa nthawi zambiri chimakhala mu mafuta otsika kwambiri, omwe amasokoneza ntchito. Pochotsa injini ya VW Polo, nthawi zina kumakhala kokwanira kutengera "zakufa" zonyamula ma hydraulic, ngakhale nthawi zambiri zimafunikira kuyang'ana chifukwa chake.
2. Vuto lina ndi kuvala kwa ma beya akuluakulu a crankshaft. M'malo ozizira, zigawo zachitsulo zamagulu otsutsana zimakhala ndi miyeso yaying'ono kwambiri, mipata imawoneka pakati pawo. Injini ikatenthetsa, magawowo amakula ndipo mipata imasowa, kugogoda kumasiya. Izi ndi momwe injiniyo imayendera, yomwe yayenda kale makilomita masauzande ambiri, posachedwa, m'malo mwa magawo ofunikira adzafunikabe.
3. Kugogoda mu clockwork. Kukazizira, mipata ikuluikulu imawonekera m'mabedi a camshafts. Komanso, kuyimbako kumatha kuwonjezeredwa ndi unyolo wosapambana kwathunthu.
4. Chifukwa choopsa kwambiri ndi kuvala kwa pistoni pamodzi ndi mphete. Ngati pali mikangano pa pistoni kapena silinda, pakapita nthawi izi zingayambitse injini kugwidwa. Nthawi zambiri zimakhala zosavuta kuchita, kotero malinga ndi malamulo a fizikiki, amapachika pang'ono pa injini yozizira, koma chifukwa cha kuwonjezereka kwa kutentha, amagwera pamene kuvala sikuli kovuta kwambiri. Ngati mwini galimotoyo anamva kuti kugogoda kukupita patsogolo ndipo sikuchoka pamene kutenthedwa, ichi ndi chisonyezo cha kuphulika kwachangu kwa injini.

Injini imakhala ndi Polo sedan

Gulu la eni magalimoto lidazindikira kuti kugunda injini yozizira nthawi zambiri sikukhudzana ndi mtunda. Ndizomveka kumva phokoso lachilendo mu injini yomwe yayenda makilomita pafupifupi 100, koma nthawi zambiri kugogoda kumawonedwa pa 15 zikwi ndipo ngakhale kale. Chifukwa cha kukambirana, anaganiza kuti kugogoda zambiri khalidwe la injini CFNA 1.6, amene ali ndi magalimoto ogulitsidwa ku Russia ndi mayiko ena. Ngakhale msonkhano wa ku Germany, uli ndi zinthu zomwe zimapanga mikhalidwe yachilendo ya injini yogwira ntchito ngakhale ndi mtunda wochepa:

1. Kuchuluka kwa utsi wambiri. Chifukwa cha mapangidwe ake, mpweya wotulutsa mpweya umachotsedwa bwino pambuyo poyaka. Masilinda ena (akugwira ntchito) amapangitsa kuti pakhale kuvala kosagwirizana zomwe zimapangitsa kuti azizizira.
2. Maonekedwe apadera a masilindala ndi zokutira zawo zikutanthauza kuti kudumpha kumachitika mukadutsa pakati pakufa pamwamba. Pamene ikutha, imakhala yamphamvu kwambiri komanso yomveka, kukhala yofanana ndi rhythm. Kwa nthawi yayitali zitha kukhala zotetezeka, koma lotale imayamba - wina adzakhala ndi mwayi ndipo apita patsogolo, ndipo wina amakhala ndi zokopa pamakoma a masilindala.

Pilo kugogoda

Nthawi zina chifukwa chake sichingakhale mu injini yokha, koma momwe imayikidwa m'galimoto. Zoyikira injini zikatha kapena kuchepera, zitsulo zimatha kunjenjemera motsutsana ndi chitsulo. Onaninso malowa mosamala ngati mukugula galimoto yakale.

Mtsamiro wotopa nthawi zambiri umakutidwa ndi zokutira zingapo, zomwe, zitamasula pang'ono, zimatha kuyamba kunjenjemera pozizira.

Knock prop

Tsoka ilo, palibe amene adaletsa kutopa kwachitsulocho. Mtsamiro wa injini, womwe umakhala ndi katundu wokhazikika, ukhoza kuphwanya kukhulupirika kwake, ma microcracks amawonekera pa izo. Kusawoneka kwake pakuwunika kwakunja kumayambitsa chisokonezo pakati pa eni ake ambiri.

Werengani komanso Momwe mungasinthire ma brake pads pa Volkswagen Polo Sedan

Zomwe zingatheke

Anthu ena okonda magalimoto akhala akukwela Polo sedan kwa zaka zambiri ndi nyengo yozizira. Injini yokha ndiyodalirika komanso yolumikizidwa bwino. Komabe, ngati mukumva phokoso losokoneza, ndi bwino kutengera galimotoyo kumalo ovomerezeka kapena ogulitsa kuti athetse mavuto. Monga miyeso pambuyo pa disassembly, mutha kuchita izi:

• m'malo mwa hydraulic lifters;
• zoikamo nthawi;
• m'malo mwa crankshaft bushings;
• m'malo mwa gulu la pisitoni ndi utsi wambiri.

Chidule

Pamabwalo apadera mungapeze zidziwitso kuti ngakhale mutakonza, kugogoda kumabwerera pambuyo pa makilomita khumi ndi awiri kapena zikwi ziwiri. Tiyenera kuvomereza kuti kugogoda kwa injini ya CFNA ndikofanana ndipo nthawi zambiri kumakhala kosavulaza. Komabe, kutsimikiza kotereku kungaperekedwe kokha pambuyo pozindikira bwinobwino galimotoyo.
