Mafuta akalowa m'madzi, ngati sakuchitidwa nthawi yake, amachititsa zotsatira zoopsa. Ngati mafuta alowa pang'onopang'ono, amayambitsa kusintha kwa mbali zofunika kwambiri monga crankshaft ndi ndodo yolumikizira injiniyo, zomwe zimapangitsa injini kugwedezeka, ndipo zikavuta kwambiri, ziwalozo zimathyoka ndipo injiniyo imachotsedwa. Ndiye nchiyani chimayambitsa madzi mu injini? Nazi zifukwa zingapo zomwe mafuta amalowa m'madzi.
1. Kutseka kwamadzi kwa injini ndi kutayikira
Chifukwa cha kuwonongeka kwa sikelo, madzi amatsekedwa ndi dzimbiri, ndipo madzi ozizira amalowa mumsewu wamafuta kuchokera mumsewu wamadzi mpaka kukafika ku poto yamafuta. Izi ndizofala, choncho fufuzani madzi otsekedwa nthawi zambiri.
2. Radiyeta yamafuta yawonongeka
Ngati chitoliro cha radiator chawonongeka, madzi omwe ali kunja kwa radiator adzalowa mu radiator ya mafuta, zomwe zimapangitsa kuti mafuta alowe m'madzi.
3. Ming'alu imawonekera muzitsulo za silinda
Pamene madzi ozizira akukhudzana ndi cylinder liner yogwira ntchito, ming'alu imakhala yosavuta kuchitika. Zikachitika ming'alu, madzi ozizira amalowa mwachindunji mu silinda ndikulowa mu poto yamafuta kudzera pakhoma la silinda, zomwe zimapangitsa mafuta kukhala oyera, ndipo mafutawo amasanduka oyera. Zidzabweretsa mavuto monga kusayaka kwa injini ndi utsi woyera. Nthawi zambiri, chotengera cha silinda sichimakonda ming'alu, koma nthawi zina, mwachitsanzo, m'nyengo yozizira, madzi ozizira samadzazidwa ndi antifreeze, zomwe zimapangitsa kuti azizizira, zomwe zingayambitse phula la silinda.
4. Chisindikizo cha Cylinder liner chawonongeka
Kuwonongeka kwa mphete yosindikizira ya cylinder liner ndizomwe zimayambitsa kulowetsa mafuta, kotero mukathetsa vuto lomwe lalephera, onetsetsani kuti muwone ngati mphete yosindikiza ya silinda ili bwino.
5. Kuwonongeka kwa silinda mutu gasket
Ngati cylinder head gasket yawonongeka ndipo kuthamanga kwa madzi kumathamanga, madzi omwe ali mumtsinje wamadzi amalowa mumtsinje wa mafuta, zomwe zimapangitsa kuti mafuta alowe m'madzi. Kuwonongeka kwa cylinder head gasket ndi chimodzi mwazifukwa zomwe mafuta amalowa. Pambuyo pa disassembly iliyonse yamakina, yesani kugwiritsa ntchito silinda yatsopano yamutu kuti mupewe kutayikira kwamafuta a injini chifukwa cha kutayikira kwa cylinder head gasket.
