Masilinda oterera
Kuwonjezeka kwa kutentha ndi mphamvu zomwe zimagwira ntchito mkati mwa injini zimakakamiza kugwiritsa ntchito zinthu zowonjezereka zowonjezera chitetezo chawo. Kuphatikiza pa mafuta, njira zapadera zimayambitsidwa kuti ziteteze injini kuti zisavale.
Pa ntchito ya injini, zinthu zosiyanasiyana zitsulo zimagwirizana mmenemo, choncho nthawi zambiri zimatsutsana wina ndi mzake ku digiri imodzi kapena imzake. Kukangana kumeneku, kumbali imodzi, kumachepetsa mphamvu ya injini, yomwe imayenera kutaya mphamvu zina zomwe zimapangidwira kuti zithetse kusagwirizana, ndipo kumbali ina, zimayambitsa kuwonongeka kwa injini, zomwe zimabweretsa kuwonongeka kwa injini. bwino ndi ntchito.
Chifukwa cha njira zotsutsana ndi mikangano, kutentha kwa injini kumachepetsedwa. Mafuta a injini satenthedwa, amakhala osalimba kwambiri kwa nthawi yayitali, ma silinda amakhala olimba, motero kupanikizika kumawonjezeka.
Miyezo yambiri imachokera ku Teflon, yomwe, potsatira injini kapena zigawo zotumizira, zimachepetsa mikangano, kuteteza ziwalo zawo zogwirira ntchito ku abrasion.
Kuphatikiza pa Teflon, palinso njira za ceramic zotetezera injini ndi ma gearbox. Ma ufa a ceramic omwe ali mkati mwake amapereka glide. - Kukonzekera kwa Ceramic kumamatira bwino ku zigawo zachitsulo, chifukwa chakuti mayunitsi onse otsutsana amatetezedwa bwino. Amakhalanso ndi coefficient yocheperako ya kukangana komanso kupirira kutentha kwambiri. - akutero Jan Matysik kuchokera ku kampani yotumiza kunja, kuphatikiza chitetezo chagalimoto cha Xeramic ceramic.
Makampani amafuta "samalimbikitsa" kugwiritsa ntchito othandizira. Asayansi ochokera ku Institute of Petroleum Technologies amakayikiranso za mtundu uwu wa zowonjezera, koma amavomereza kuti atakumana ndi vuto limodzi ndi mmodzi wa iwo, sanayese lotsatira.
Komabe, si onse amene amawakana. Malinga ndi kafukufuku wopangidwa ndi Institute of the Automotive Industry, atagwiritsa ntchito Xeramic, kugwiritsa ntchito mafuta kunatsika ndi 7%, ndipo mphamvu idakwera ndi 4%.
Posachedwapa ndi imodzi mwa mayeso a sabata yamagalimoto akuwonetsa kuti malonjezo a opanga obwezeretsanso akukokomeza kwambiri. Zida za ceramic zidakhala zabwino kwambiri pamayeso awa.
Musayembekezere zozizwitsa kuchokera ku mankhwala oterowo. Kuchokera pa khumi kapena awiri peresenti yolonjezedwa kuwongolera, muyenera kudutsa kumapeto kwa "mnyamata" ndiyeno zotsatira zake zidzakhala zenizeni. Eni ake a magalimoto akale okhala ndi mtunda wautali adzawonadi phindu lalikulu. Pamene injini yatha, m'pamenenso imakhala yosavuta kukonza.
Kuipa kwa kugwiritsa ntchito ndalama zoterezi m'galimoto yatsopano, makamaka pansi pa chivomerezo, ndizowopsa kuti pakagwa kuwonongeka sikudzakhala kolakwa. Pakachitika kuwonongeka kwa injini, nthawi zina zimakhala kuti mwiniwake wagalimoto ndiye wolakwa, yemwe adasintha mafutawo pakusefukira kwa mpweya.
Inde, muyeneranso kusankha mankhwala kuchokera ku makampani odziwika omwe akhala pamsika kwa zaka zambiri ndipo ali ndi mbiri yabwino. Makamaka zosasangalatsa kungakhale kukonzekera munali chitsulo particles, amene ayenera kudzaza cavities injini mbali. Ngati tinthu tachitsulo takula kwambiri, timatsekereza zosefera.
