Ndi mavuto ati omwe mungayembekezere ngati mafuta a injini alowa mu fyuluta ya mpweya, ndi choti muchite
Mwiniwake aliyense wamagalimoto odziwa zambiri kamodzi mu mbiri yake adawona zosefera zopaka mafuta. Inde, ichi ndi chizindikiro cha kulephera kugwira ntchito, koma ndizovuta bwanji? Portal "AvtoVzglyad" adapeza nkhani yonyansa.
Zomwe zimachitika, panthawi yokonza, mbuyeyo amatulutsa fyuluta ya mpweya ndikuwonetsa mwiniwake wamafuta a injini ali ngati filimu yowopsa. Kupeza mafuta ndi mafuta mu "mpweya wotengera" ndi chizindikiro chotere. Ndipotu, ichi ndi lingaliro wandiweyani pa kukanika kwa mtengo kwambiri ndi zovuta kukonza unit galimoto iliyonse - injini. Popeza ambiri chikhumbo kuchita mabuku m'malo wa unit, m'malo disassembling ndi kufunafuna chifukwa, mphambu adzakhala sikisi ziwerengero. Koma kodi mdierekezi ndi woipa monga momwe anapakidwira?
Chifukwa choyamba komanso chofunikira chomwe mafuta amalowa mu "mpweya" ndi njira zotsekeka pamutu wa silinda. Apa, maola ambiri akusokonekera kwa magalimoto, komanso kusasunga nthawi yautumiki, komanso mafuta "pakuchotsera" nthawi yomweyo amabwera m'maganizo. Mosakayikira, njira yotereyi idzatumiza mwamsanga injini yamakono yamakono kumtunda, ndipo nthawi zambiri zimakhala zopindulitsa kwa wogulitsa kuti atsimikizire kasitomala wake kuti chipangizocho ndi chosayenera kukonzanso. Koma sikoyenera kuvomereza ngongole ina nthawi yomweyo, chifukwa mungayesere kuyeretsa injini - pali njira zambiri ndi mankhwala a galimoto. Komanso: ngalande zamafuta "shati" sizili chifukwa chokhacho kuti mafuta a injini alowe munyumba ya fyuluta ya mpweya.
"Vuto"li likhoza kuchitikanso chifukwa cha kuwonjezeka kwa mphete za pistoni, zomwe zimapangitsa kuti pakhale kuponderezedwa mkati mwa masilinda ndi makulidwe a filimu yamafuta pamakoma. Ngati utsiwo udasanduka imvi, ngati gulu lamadzulo pa "galasi" lachigawo, ndiye kuti sikungakhale koyipa kuyeza kuponderezedwa mu masilindala musanawaike kuti akonze - zikutheka kuti vuto lili m'mphetezo. Zimatha, kupanikizika mu crankcase kumawonjezeka, ndipo valavu ya mpweya wa crankcase imayamba kutaya kwambiri. Mukuganiza kuti? Ndiko kulondola, mu dongosolo lotengera mpweya. Izo ndi molunjika kwa mpweya fyuluta.
Mwa njira, za valavu ya PCV, yotchedwa crankcase ventilation. Izi, modabwitsa, zimatsukidwa nthawi ndi nthawi komanso zimasinthidwa. Kuchuluka kwa mafuta otsika kwambiri, omwe nthawi zambiri amapangidwa ndi mafuta onyenga, omwe tsopano agonjetsa msika wapakhomo, ngakhale kuti makampani amafuta akuyesetsa, komanso zovuta zogwirira ntchito - mzindawu wokhala ndi mayendedwe ake siwosavuta kupirira ndi injini iliyonse kuposa chovuta kwambiri panjira - kuchita "zonyansa" zawo.
Ndipo "chizindikiro choyamba", kusonyeza kufunika koyeretsa "kuyeretsa kwakukulu" mu injini, kudzakhala kutsekeka kwa valve yokakamiza yomweyi. Maonekedwe ake adzakuuzani dongosolo la zochita zina, koma kuchita zikusonyeza kuti zaka ziwiri kapena zitatu mu "nkhalango mwala" mfundo imeneyi ndi malire mtheradi.
Ndizomvetsa chisoni kuti ntchitoyi siili m'mabuku ogwiritsira ntchito, komanso "mipukutu" yogulitsa, chifukwa kuyang'ana ntchitoyo, komanso kuyeretsa kapena kusintha sensa ya PCV, kumawonjezera kwambiri moyo wa injini. Makamaka zovuta zamakono, zolemedwa ndi turbine. Kupatula apo, ndi sensa yolakwika yomwe ingayambitse kuthamanga kochulukirapo mkati mwa crankcase ndikutulutsa mafuta motsatira mu fyuluta ya mpweya.
Mafuta mu fyuluta ya mpweya ndi chizindikiro chosakayikira cha ntchito yolakwika ya injini, koma n'zosatheka kufotokozera ndi kupanga chisankho chokhudza tsogolo la galimoto pa zomwe mukuwona. Ndikofunikira kuzindikira kuti injini imafunikira chidwi, ndipo makina onse amafunikira ndalama. Komanso, kuchuluka kwa ndalama zomwe zimayikidwa nthawi zambiri zimadalira kukhulupirika kwa mbuye komanso chidziwitso cha mwiniwake.
