Chifukwa chiyani muyenera kusintha mafuta mu injini, ngakhale akadali opepuka
Mafuta mu injini akuwoneka kuti ndi nthawi yoti asinthe, komabe amawoneka atsopano. Mtundu ndi wopepuka, injini imayenda bwino: ndiko kuti, palibe chodetsa nkhawa. Tsamba la AvtoVzglyad likuwona ngati kuli koyenera kuchedwetsa kusintha mafuta pamene zikuwoneka kuti mutha kudikirira pang'ono ndi ndalama zowonjezera.
Choyamba muyenera kudziwa chifukwa chake mafuta a injini amadetsedwa, ndipo chifukwa chake amakhalabe opepuka, ngakhale atatha makilomita 8000-10. Apa tikusungirako kuti, kwenikweni, sizikuwoneka ngati zatsopano, chifukwa njira ya okosijeni yamafuta ikuchitika ndipo, mwatsoka, ndiyosapeŵeka. Komabe, mtundu wa mafuta a opanga ena umakhala wopepuka kuposa ena. Koma chifukwa chakuti oxidation inhibitors amawonjezeredwa ku mafuta. Amachepetsa njira yosinthira "mithunzi ya imvi".
Oxidation imachitika mwachangu mumafuta amchere, osati mu "synthetics". Choncho, "madzi amchere" amadetsedwa mofulumira kwambiri. Kawirikawiri, ngati mafuta sanasinthe mdima pamtunda wa makilomita pafupifupi 5000, izi zikutanthauza kuti zowonjezera zomwe zimachepetsa makutidwe ndi okosijeni "zimatulutsa" kuchokera pamtima.
Kupanga mafuta amtundu uliwonse wamakono, zinthu ziwiri zimagwiritsidwa ntchito: zomwe zimatchedwa maziko ndi phukusi lowonjezera. Zotsirizirazi zimakhala ndi zoyeretsa komanso zoteteza, zoyeretsa injini ku mwaye ndi zina zoyipa zovala. Zomwe zimayaka zimatsukidwa mu crankcase ndikukhazikika pamenepo, osati pazigawo za injini. Kuchokera apa, lubricant imakhala yakuda.
Ngati mafuta amakhalabe oyera pamtunda wothamanga, izi zimangosonyeza kuti alibe khalidwe labwino, ntchito zotetezera ndizofooka, ndipo zinthu zoyaka moto zimakhalabe pamagulu a gulu la cylinder-piston. Popita nthawi, izi zidzasokoneza magwiridwe antchito amagetsi. Mafutawa amafunika kusinthidwa nthawi yomweyo.
