Nthawi zambiri kutulutsa injini sikungapeweke, Makamaka mukamagwiritsa ntchito mafuta oyipa, Pali zosafunika zambiri mumafuta, Sikuti zimangowonjezera kukanika kwa injini,
Itha kupangitsanso mafuta kutulutsa mafuta.
Tiyeni tikambirane za kutuluka kwina pachikuto cha chipinda chamagetsi.
Nchiyani chimapangitsa chipinda cha valve kutayikira? Kodi mungathane nawo bwanji?
Kodi injini yovundikira ma injini ndi chiyani?
Chivundikiro cha valavu yamainjini gasket- chodziwika kuti chipinda chophimba cha valavu. Ndi membala wosindikiza wa gawo lalikulu la injini. Idasindikizidwa ndi mafuta oyendera mafuta ofanana ndi poto wamafuta kuti mafuta asatuluke pomwe injini ikuyenda.Mutu wamphamvu wofanana ndi thupi lamphamvu, valavu yofananira imayikidwa pamutu wamphamvu, ndipo thupi lamphamvu limakhala chopangidwa kukhala chipinda chosindikizira chosindikizidwa, munthawi zina, kulola kuti chisakanizo choyaka chikuwotchera mkatikati mwake. Chivundikiro chapamwamba cha chipinda chamagetsi, chivundikiro cha pansi pamiyala, thupi loyambira pansi, komanso mafuta oyambira pansi.
Chifukwa chiyani chivundikiro cha valavu chidzakhala kutayikira kwamafuta?
1- Kukalamba kwa chivundikiro cha valavu kumapangitsa kuti mafuta achuluke.
Choyamba, chipinda chamagetsi chogwiritsira ntchito chakhala chikugwiritsidwa ntchito kwanthawi yayitali, ndikupangitsa kukalamba ndikulephera kusindikiza kutayikira kwamafuta.Kusindikiza gasket pazinthu za mphira, chifukwa chokhala ndi moyo wagalimoto ndikutalika kwambiri, zinthu za mphira zidzakalamba, zidzakhala zolimba, pakudontha kwamafuta.
Popeza chipinda cha valavu chili kumtunda kwa injini, mafuta amayenda pansi pamutu wamphamvu pambuyo poti chipinda cha valavu chikutuluka, chifukwa thupi la injini limagwira
Kutentha kwambiri, mafuta omwe amamatira kumtunda kwa thupi amatuluka pang'onopang'ono, ndikupanga utsi wowopsa.
Poterepa, ingotsegulani chivundikiro cha chipinda cha valavu ndikusintha gasket.valve chivundikiro cha gasket chosinthira sichokwera
2. -Vallet crankcase mpweya wabwino watsekedwa
PCV valavu ya crankcase ventilation system ndi yotsekedwa, yomwe imayambitsa kupsyinjika kwakukulu mkati mwa makina ndipo pamapeto pake imayambitsa kutayikira kwamafuta pansi pothinikizika.Ngati vuto ili silikupezeka, limadzetsa mavuto ena pambuyo pake, monga crankshaft mafuta seal leakage ndi zina zotero. ndizosavuta kudziwa ngati valavu ya PCV ikugwira ntchito bwino: pansi pazinthu zopanda pake, momwe ntchito yama PCV ingakhalire nthawi yomweyo imatha kuyesedwa poyesa cholowera cha crankcase ndi chala chanu.
Njira yoyendera valavu ya PCV ya crankcase yokakamiza mpweya wabwino:
Pangani injini kuti idle, chotsani valavu ya PCV payipi ya chivundikirocho, ndipo muwone ngati valavu ya PCV yatsekedwa. Mukayika dzanja lanu pa cholumikizira cha PCV, zala zanu zimatuluka.
Njira ina yoyendera ndikuchotsa chitoliro cholumikiza pa fyuluta ya mpweya mukatha kuyika valavu ya PCV, ndikuphimba pang'onopang'ono chikopacho ndi pepala. Kupsyinjika kwa crankcase kukachepa (za IMIn), ziyenera kukhala zowonekeratu kuti pepala lanyama limakokedwa kutsegulira kwa chitoliro Kuphatikiza apo, mutayimitsa injini, chotsani valavu ya PCV ndikuyang'ana pamanja. Ngati pali phokoso "dinani", valavu ya PCV imasinthasintha ndipo imapezeka.
3- Kulephera kwa mbali zina za injini kumabweretsa mafuta.
Kukalamba kwa mphete ya pisitoni ya injini kumabweretsa kusindikiza kosalala. Injini ikamathamanga kwambiri, chodabwitsa cha kutsekemera kwa silinda kumachitika, komwe kumabweretsa mpweya wambiri wamagetsi, ndipo pamavuto akulu, zimabweretsa kuwonongeka kwa valavu ya gasketsealant ndi mafuta.
Kuphatikiza apo, chifukwa cha mafuta osauka, kuphatikizika kwakukulu kwa pisitoni pomata, kukhazikitsidwa kwa gasket wamagetsi sikuli koyenera, kumabweretsa mphamvu zosagwirizana, ndi zina zambiri, mavuto onsewa amabweretsa kuwonongeka kwa valavu yovundikira gasketand kutayikira kwamafuta.
Kuwonongeka kwa kutayikira kwa gasket pachikuto cha mphira
Samalani chifukwa cha kutsekemera kwamafuta a gasketto kutulutsa mafuta .Kuwononga injini.
Pali ngozi zowopsa monga moto womwe umayambitsidwa ndi kutayikira kwamafuta mu gasket yovundikira.
Chifukwa cha kutayikira kwamafuta pachikuto cha chipinda cha valavu, mafuta omwe amatuluka amayenda kutsikira m'thupi la injini. Chifukwa cha kutentha kwa thupi la injini pomwe injini ikugwira ntchito, mafuta omwe amamatira kumtunda kwa injini yamphamvu amayamba kutuluka pang'onopang'ono ndikupanga fungo lamphamvu. Zikachitika, mafuta amalowa mgalimoto limodzi ndi makina owongolera mpweya, zomwe zimakhudza malo agalimoto.
Chachiwiri, chipinda cha valavu chikaphimbira ndikumamatira kwamafuta pamafuta ambirimbiri a injini, ndiye kuti vuto silili lophweka, kulawa kwakuthwa, galimoto yothamanga kwambiri nthawi yotentha, chifukwa kutentha kwazinthu zambiri kumakweza kwambiri, kumapangitsa kulumikizana pamoto wambiri wamafuta, poyatsira zinthu zina zomwe zimayaka, pamapeto pake zimatha kuyambitsa moto m'chipinda chamoto
