Kulumikizana kwa plunger kukakakamira, ntchito ya bwanamkubwa idzakhudzidwa, zomwe zimapangitsa kuti injini ya dizilo ikhale yosasunthika, ndipo pazovuta kwambiri, ngozi yothamanga ndi moto wa injini ya dizilo.
Zifukwa zomata pampu ya jakisoni wamafuta ndi izi:
Posonkhanitsa, zigawo zogwirizanitsa zimayikidwa molimba kwambiri, thupi la mpope ndi mkono wa plunger zimawonongeka mosavuta, ndipo pazovuta kwambiri, zidzasweka;
Popeza msonkhanowo suli woyenerera, kapena zinthu zachilendo zidzagwera mmenemo, pakati pa ziwalozo padzakhala kuyimilira;
Kapena pali madzi mu injini mafuta, ndi mamasukidwe akayendedwe a injini mafuta ndi mkulu kwambiri, zomwe zidzachititsa ntchito wosasinthasintha m'nyengo yozizira, amene kuwononga ntchito ya bwanamkubwa, ndipo ngakhale kuyambitsa injini flameout ndi "liwiro" chodabwitsa, amene. pamapeto pake zidzawononga makina onse.
Pampu yojambulira mafuta ikaphwanyidwa kapena kupunduka, mbali zake ziyenera kusinthidwa.
Mafuta olakwika omwe amagwiritsidwa ntchito pochotsa pampu yatsopano yojambulira mafuta ndiyenso chifukwa chomamatira.Ngati ndende yeniyeni ya colloid ndi acidity ya mafuta a dizilo yomwe imagwiritsidwa ntchito ndi yokwera, filimu yotsalira yamafuta imamatira pamwamba pazigawo zolumikizana bwino za mpope wa jekeseni wamafuta pambuyo pochotsa zolakwika.Chochitika chokakamira chidzachitikanso pambuyo pake.
Ngati pampu yatsopano ya jekeseni ya mafuta sichikusungidwa bwino, pali vuto ndi phukusi, ndipo zipangizo zotetezera chinyezi ndi zowonongeka zikusowa kapena zowonongeka, ndi zina zotero, ndizo zifukwa zomwe zimamatira.
