Mafuta othamanga azikhala otsika kwambiri kapena osakakamiza chifukwa chovala injini, msonkhano wosayenera kapena zolakwika zina. Zolakwika monga kukakamiza kwambiri kwa mafuta kapena kubwereza mawu osokoneza bongo. Zotsatira zake, ngozi zimachitika mu kugwiritsa ntchito makina omanga, zomwe zimapangitsa kutaya kosafunikira.
1. Kupanikizika kwamafuta ochepa
Kupanikizika komwe kukuchitika ndi kuchuluka kwa kuchuluka kwa mafuta kumapezeka kuti ndi otsika kuposa mtengo wamba (0.15-0.4 MPA), siyani makinawo nthawi yomweyo. Pambuyo podikirira mphindi 3-5, konzani mafuta a mafuta kuti muwone mtundu wa mafuta ndi kuchuluka kwa mafuta. Ngati kuchuluka kwa mafuta sikokwanira, ziyenera kuwonjezeredwa. Ngati mamasukidwe amafuta ali otsika, mafuta opangira mafuta amatuluka ndipo kununkhira kwa mafuta kumachitika, mafuta amasakanikirana ndi mafuta. Ngati mafuta ndi oyera oyera, madzi ndi osakanizika mumafuta. Chongani ndikuchotsa mafuta kapena kutaya kwamadzi ndikusintha mafuta monga ofunikira. Ngati mafuta akukumana ndi zofunikira zamtunduwu ndi kuchuluka kumakhala kokwanira, kumasula mapulani a Screen Plack yayikulu ndikusintha crankshaft. Ngati mafuta ambiri amatulutsidwa, chilolezo cha kukhwima chachikulu, cholumikizira ndodo zophatikizika ndi camshaft zitha kukhala zazikulu kwambiri. Chilolezo choberekera chimayenera kufufuzidwa ndikusinthidwa. Ngati pali mafuta ochepa, itha kukhala yosefedwa, kutayidwa kwa valavu yolephera kapena kusintha kosayenera. Pakadali pano, Fyulutayo iyenera kutsukidwa kapena kufufuzidwa ndi kufooketsa kwa valavu yosinthidwa. Kusintha kwamphamvu kwamphamvu kuyenera kuchitika pamayeso ndipo sikuyenera kuchitika. Kuphatikiza apo, ngati pampu yamafuta itatopa kwambiri kapena ganje la chisindikizo limawonongeka, popangitsa kuti pampu yamafuta kuti isapatse mafuta, zimapangitsanso kupanikizika kwa mafuta kukhala otsika kwambiri. Pakadali pano, ndikofunikira kuyang'ana ndikukonza pampu yamafuta. Ngati palibe vuto lomwe limapezeka pambuyo pa ma cheke pamwambapa, zikutanthauza kuti gauge yopaka mafuta ndi yopanda dongosolo komanso gauge ya mafuta atsopano.
2. Palibe mafuta
Pa ntchito yamakina omanga, ngati chisonyezo cha mafuta chimayatsa ndipo makina othamanga a Guege Counter Point 0, makinawo amayenera kuyimitsidwa nthawi yomweyo ndipo moto uyenera kuyimitsidwa. Kenako onani ngati mapaipi yamafuta imatulutsa kwambiri chifukwa cha kututa mwadzidzidzi. Ngati kutsika kwakukulu kwa mafuta kunja kwa injini, kumasula kulumikizana kwa magetsi. Mafuta akathamangira msanga, kuthamanga kwa mafuta kumawonongeka. Popeza fyuluta yamafuta imayikidwa pa cylinder block, pamafunika kukhala pachikuto cha pepala. Ngati khushoni ya pepalayo yakwezedwa kapena itlet dzenje la mafuta limalumikizidwa ndi bowo lamtundu, mafuta sangathe kulowa gawo lalikulu. Izi ndi zowopsa kwambiri, makamaka injini ya diesel yomwe yangotukuka kumene. Ngati palibe zochitika zosadziwika zomwe zapezeka pamwambapa, cholakwacho chitha kukhala pampu yamafuta ndi pampu yamafuta zimayenera kusankhidwa ndikukonzedwa.
3. Mafuta olimbitsa thupi kwambiri
M'nyengo yozizira, pomwe injini ya diesel yangoyambika, idzapezeka kuti kuthamanga kwa mafuta ili pamtunda wautali ndipo kumatsika pang'ono pambuyo pakutenthedwa. Ngati mtengo wowoneka bwino wa gaigh okwera imapitilira phindu labwinobwino, valavu yopanda mphamvu iyenera kusinthidwa kuti ikwaniritse mtengo womwe watchulidwa. Pambuyo polamula, ngati kupanikizika kumakulirakulira, mtundu wamafuta uyenera kusankhidwa kuti muwone ngati mamasukidwe amafuta ndi okwera kwambiri. Ngati mafutawo siwowoneka bwino, zitha kukhala zopaka mafuta opangira mafuta amatsekedwa ndikutsukidwa ndi mafuta oyera. Chifukwa cha mafuta osakwanira a dizisoni, ndikotheka kuzungulira woyambitsa ndi crankshaft kwa mphindi 3-4 mukamatsuka (chindikirani kuti injiniyo sayenera kuyambitsa). Ngati injini iyenera kuyamba kuyeretsa, imatha kutsukidwa pambuyo kusakaniza 2/3 yamafuta ndi 1/3 ya mafuta osapitirira mphindi zitatu.
4. Kulemba kwa mapangidwe a mafuta a mafuta osunthatu ndi mtsogolo
Pambuyo poyambitsa injini yaifesel, ngati chowunikira chimakhala champhamvu champhamvu mmbuyo ndi mtsogolo, mawonekedwe a mafuta amayenera kutulutsidwa kaye kuti awone ngati sichoncho, mafuta oyenerera ayenera kuwonjezeredwa molingana ndi muyezo. Valawi vala iyenera kuyesedwa ngati pali mafuta okwanira. Ngati valavu yamasika imasiyidwa kapena kuthira bwino, valavu yamasika iyenera kusinthidwa; Ngati valavu ya Bypass ilibe bwino, iyenera kukonzedwa
