M’madera ambiri, kutentha kumakhala kotsika kwambiri m’nyengo yozizira, ndipo eni magalimoto ambiri achita manyazi chifukwa chakuti injiniyo yaundana ndi kusweka. Izi zimachitika makamaka injini yozizira ikayamba.
Kodi mukudziwa kuti injiniyo imaundana ndikusweka mpaka madigiri angapo pansi pa ziro?Kuzizira kwa injini ndi kusweka kumakhala kofala pansi pa madigiri khumi, koma osati kutentha kukafika pansi -10, chipika cha injini chimaundana ndikusweka.
Zinthu ziwiri zimafunikira pakuzizira kwa injini ndi kusweka, imodzi ndikuyamba kuzizira, ndipo ina ilibe antifreeze kapena antifreeze osakwanira.
Chifukwa chomwe injini imaundana ndikusweka ndichifukwa kuchuluka kwa madzi oletsa kuzizira kumawonjezeka akamaundana mupaipi, zomwe zimapangitsa kuti rediyeta ikule ndikusweka ndikuundana ndi silinda ya injini kapena mutu wa silinda. Panthawi imodzimodziyo, injini yozizira ikayambika, refrigerant mu injini sangathe kuyendayenda mu chitoliro kuti athetse kutentha chifukwa cha icing, yomwe ingayambitse kuwonongeka kwa injini mosavuta.
Momwe mungakonzere kuzizira kwa injini ndikusweka? Kambiranani za vutoli pogwiritsa ntchito zigawo zing'onozing'ono ndi zipangizo.
Choyamba, tiyeni tikambirane za zipangizo wamba chipika ya silinda. Masilinda agalimoto nthawi zambiri amagawidwa kukhala chitsulo choponyedwa ndi aluminiyamu. Masilinda achitsulo otayira amatha kukonzedwa. Ming'alu yaying'ono nthawi zambiri amawotcherera mpaka kufa ndi ndodo zowotcherera ndipo khoma la silinda limatha kusalalitsidwa. Ngati thupi la silinda likuponyedwa aluminium, likhoza kusinthidwa lonse, ndipo aluminiyumu yotayidwa sangathe kukonzedwa.
Pali magawo awiri a injini omwe amakonda kuzizira komanso kusweka, imodzi ndi chipika cha silinda ndipo inayo ndi mutu wa silinda.
Chophimba chachitsulo chachitsulo chikhoza kukonzedwa, koma mutu wa silinda sungathe kukonzedwa ndi kuwotcherera, ziribe kanthu kuti ndi chiyani, ukhoza kusinthidwa ndi zigawo zatsopano. Chifukwa mutu wa silinda umagwiritsidwa ntchito makamaka kusindikiza, mphamvu yowotcherera itatha kuzizira ndi kusweka sikufika pamlingo woyambirira.
Kodi mungateteze bwanji injini kuti isawume ndi kusweka?1. Bwezerani antifreeze yapamwamba kwambiri ndikusunga mulingo wamadzimadzi pamalo okhazikika. M'madera omwe kutentha kumakhala kotsika kwambiri m'nyengo yozizira, madzi oyera sayenera kugwiritsidwa ntchito ngati choziziritsa, komanso payenera kugwiritsidwa ntchito chozizira chapadera cha galimoto. Kuzizira kozizira kwagalimoto kumakhala pansi -60 madigiri, omwe angagwiritsidwe ntchito pazithunzi zambiri;
2. Ngati madzi oyera amagwiritsidwa ntchito ngati antifreeze, ndiye kuti moto utazimitsidwa, malo otsekemera amayenera kutsegulidwa kuti athetse madzi onse, ndiyeno mudzaze ndi madzi otentha mukamagwiritsa ntchito;
3. Imikani galimoto mugalaja yapansi panthaka. Kutentha kwa msewu wapansi panthaka nthawi zambiri kumakhala kokwera, ndipo antifreeze sikophweka kuzizira.
