Malangizo osinthira chivundikiro cha chipinda cha mavavu
Choyamba, onetsetsani kuti mwagwiritsa ntchito chivundikiro choyambirira cha chipinda cha valve
Kusintha chivundikiro choyambirira cha chipinda cha valve kudzathetsa vutoli. Chivundikiro choyambirira cha Peugeot Citroen chinapangidwa ndi Mega, ndipo iyi ndi nambala yake. Pali zinthu zambiri zofanana pamsika, ndipo 95% ya ubwino wake ndi madzi ambiri, ngati mulibe njira yodalirika yogulira, mwayi wogula chivundikiro cha chipinda cha valve chofanana ndi 95%. Mukapeza chivundikiro chopingasa cha valve, pali mwayi waukulu woti sichili bwino kugwiritsa ntchito, ndipo pali zoopsa zambiri zachitetezo, monga injini kuima kwa ola limodzi, chivundikiro cha valve sichikutuluka, injini imakwera pamalo otsetsereka, ndipo accelerator ikakanikizidwa, pamene kupanikizika koipa kuli kwakukulu, mafuta adzatuluka kuchokera pa chivundikiro cha valve. Mafuta a injini m'nyumbamo akakula kwambiri, amathamangira ku exhaust manifold yomwe ili pansi, ndipo n'zosavuta kuyambitsa moto wa injini pansi pa kutentha kwakukulu kwa madigiri oposa 400 mu exhaust manifold, ndipo zoopsa zachitetezo zomwe zingakhalepo ndi zazikulu. Anthu ena amasintha chivundikiro cha aluminiyamu, chivundikiro cha aluminiyamu si fakitale yoyambirira sichabwino kugwiritsa ntchito, chifukwa valavu ikayikidwa, pulasitiki imakhala yolimba, aluminiyamu siili ndi mphamvu pang'ono, ndipo kutuluka kwa mafuta kumachitika kwa nthawi ndithu. Zachidziwikire, fakitale yoyambirira ndi aluminiyamu, tiyenera kusintha chivindikiro cha aluminiyamu yoyambirira, fakitale yoyambirira ndi pulasitiki, tiyenera kusintha chivindikiro cha pulasitiki yoyambirira.
Chachiwiri, momwe mungadziwire chivundikiro choyambirira cha chipinda cha valavu
N'zovuta kwambiri kusiyanitsa pongoyang'ana chivundikiro cha chipinda cha valavu. Choyamba, yang'anani mkati mwa chivundikiro cha chipinda cha valavu chomwe chakalamba ndi kuwonongeka: malo ofiira a chivundikiro cha chipinda cha valavu chomwe chachotsedwa chawonongeka ndipo chagwa, zomwe zimapangitsa kuti mafuta aziyaka kwambiri. Yang'anani zivundikiro ziwiri zatsopano za chipinda cha valavu momwe mungasiyanitsire pakati pa chabwino ndi choipa, njira yosavuta yoyerekeza guluu pa misomali, guluu pazigawo za mtundu, ndi misomali pa fakitale yoyambirira ya Meijia. Misomali ya guluu ya zigawo za mtundu ndi yolimba, yowoneka ndi maso, ndipo guluu wa zigawo zoyambirira ndi wofanana kwambiri komanso wowoneka bwino. Guluu pa chisindikizo pansi pa chivundikiro cha mafuta nayenso ndi wosiyana kwambiri ndi guluu kumanzere kwa gawo la mtundu ndi guluu kumanja kwa chivundikiro cha chipinda choyambirira cha valavu. Chifukwa chake ngati mukufuna kusintha, ingosinthani zigawo zoyambirira.
Chachitatu, kusintha kwa chitetezo cha chivundikiro cha chipinda cha valve cha 1.6T, okwera ambiri akumana ndi kutayikira kwa mafuta a chivundikiro cha chipinda cha valve kapena mavuto a mafuta oyaka m'chivundikiro cha chipinda cha valve. Pambuyo poti kusintha sikunathetse vutoli, kwenikweni, pali zifukwa zitatu, kumbukirani mfundo zitatu zotsatirazi, kusintha chivundikiro cha chipinda cha valve sikuchotsa. Choyamba, chivundikiro choyambirira cha chipinda cha valve, chomwe ndi chinthu chofunikira; Mfundo yachiwiri, mutatsegula chivundikiro cha chipinda cha valve, nthawi yozizira iyenera kukhala yokwanira, mfundo yachitatu, malinga ndi mphamvu yokhazikika, kuti muyike zomangira, bola mfundo zitatu zomwe zili pamwambapa, zitha kukhala yankho labwino ku vutoli, vuto la chivundikiro cha chipinda cha valve si vuto la kapangidwe.
Chachinayi, timaganizira kwambiri za kupanikizika koipa
Kupanikizika koipa kwa injini ya 1.6T sikudziwika bwino kwa anthu ambiri, ndipo tikupatsani mtengo uwu lero kuti tithandizire kuwunika momwe mafuta akuyaka mtsogolo. Choyamba, pali chida choyesera kupanikizika koipa, galimoto yotentha ikatha, kuzindikira kupanikizika koipa, kuyika mbali imodzi ya payipi mu doko lodzaza la gauge ya mafuta, ndikuyika mbali inayo ngati gawo la mbar, mutha kuyamba kuyesa. Mtengo wabwinobwino wa 1.6T pafupifupi 35 pamakhala kusintha pang'ono, ngati kuchepera 25 kukuyamba kugwiritsa ntchito mafuta, panthawiyi kugwiritsa ntchito njira zachikhalidwe potsegula chivundikiro cha mafuta kutulutsa gauge ya mafuta sikuwonedwa, pafupifupi kungakhale pafupi makilomita 3000-4000 pa lita imodzi ya mafuta ogwiritsidwa ntchito. Ngati ndi yotsika kuposa 12, padzakhala kugwiritsa ntchito mafuta kosazolowereka, ndipo kugwiritsa ntchito lita imodzi ya mafuta kwa makilomita mazana angapo kapena makilomita chikwi chimodzi ndi kofala. Makamaka pamene chivundikiro choyamba cha chipinda cha valve chikukalamba, kugwiritsa ntchito mafuta poyendetsa mofulumira kwambiri mumzinda sikudziwika, ndipo kugwiritsa ntchito mafuta poyendetsa mofulumira kwambiri kudzakhala koonekeratu.
Kuti tifotokoze mwachidule vuto la kuyaka mafuta lomwe limayambitsidwa ndi chivundikiro cha chipinda cha valve cha magalimoto ovomerezeka, samalani mfundo ziwiri: choyamba, sinthani chivundikiro choyambirira cha chipinda cha valve, ndipo chachiwiri, pezani malo owunikira akatswiri, monga masitolo apadera azamalamulo ndi masitolo ogulitsa a Sunshine Artisans. Mafuta oyaka omwe amayambitsidwa ndi chivundikiro cha chipinda cha valve akhoza kukhala kuyambira 4000 mpaka 600 L, ndizotheka. Gawo loyamba si lalikulu kwambiri kugwiritsa ntchito lita imodzi ya mafuta kwa makilomita 4000, gawo lotsatira limawonongeka kwathunthu kugwiritsa ntchito lita imodzi ya mafuta kwa makilomita 1000.
