Pampu yamafuta ndi chipangizo chodziwika bwino chomwe chimagwiritsidwa ntchito kutengera zamadzimadzi (nthawi zambiri mafuta amadzimadzi kapena mafuta opaka) kuchokera kumalo ena kupita kwina.Ili ndi ntchito zosiyanasiyana m'magawo ambiri, kuphatikiza makampani opanga magalimoto, malo opangira ndege, makampani opanga zombo ndi kupanga mafakitale, ndi zina zambiri.
Mfundo yogwiritsira ntchito pampu yamafuta imatha kufotokozedwa mophweka monga: kusuntha madzi kuchokera kumalo otsika kwambiri kupita kumalo othamanga kwambiri kudzera muzitsulo zomwe zimapangidwa ndi kayendedwe ka makina.Zotsatirazi zidzafotokozera mwatsatanetsatane mfundo zogwirira ntchito za mapampu awiri amafuta omwe amagwiritsidwa ntchito.
1. Mfundo yogwiritsira ntchito pampu yamagetsi:
Pampu ya giya ndi pampu yodziwika bwino yosamuka yomwe imakhala ndi magiya awiri olumikizana wina ndi mnzake.Giya imodzi imatchedwa zida zoyendetsera ndipo ina imatchedwa zida zoyendetsedwa.Pamene zida zoyendetsa galimoto zimazungulira, zida zoyendetsedwa zimazunguliranso.Madziwo amalowa m'chipinda cha mpope kudzera mumpata pakati pa magiya ndipo amakankhidwira kumalo otulukira pamene magiya akuzungulira.Chifukwa cha ma meshing a magiya, madziwo amapanikizidwa pang'onopang'ono m'chipinda chopopera ndikukankhira kumalo othamanga kwambiri.

2. Mfundo yogwiritsira ntchito pampu ya pistoni
Pampu ya pisitoni ndi pampu yomwe imagwiritsa ntchito pisitoni kuti ibwezere m'chipinda chopopera kukankhira madzi.Amakhala ndi pistoni imodzi kapena zingapo, masilindala ndi mavavu.Pamene pisitoni ikupita patsogolo, mphamvu ya m'chipinda cha mpope imachepa ndipo madzi amalowa m'chipinda chopopera kudzera mu valve yolowera mpweya.Pamene pisitoni imayenda chammbuyo, valavu yolowera imatseka, kuthamanga kumawonjezeka, ndipo madzi amakankhidwira kutulukira.Vavu yotuluka imatsegulidwa ndipo madziwo amamasulidwa kumalo othamanga kwambiri.Kubwereza ndondomekoyi, madziwo amatengedwa mosalekeza kuchokera kumalo otsika kwambiri kupita kumalo othamanga kwambiri.
Mfundo zogwirira ntchito za mapampu awiriwa amafuta zimatengera kusiyanasiyana kwamadzimadzi kuti akwaniritse kayendedwe kamadzi.Kupyolera mu kayendetsedwe ka zipangizo zamakina, madzi amathiridwa kapena kukankhidwa, motero amapanga kuthamanga kwina, kulola madzi kuyenda.Mapampu amafuta nthawi zambiri amakhala ndi thupi la mpope, chipinda chopopera, chipangizo choyendetsa, ma valve ndi zinthu zina kuti azindikire kayendedwe ndi kuwongolera zamadzimadzi.
