Tsogolo ndi valavu yoyendetsedwa yomwe imayendetsa mpweya wa mpweya kulowa injini. Mafuta akalowa pachipaso, udzasakanikirana ndi mafuta ndikukhala osakaniza ophatikizika, omwe adzawotcha ndi kugwira ntchito. Imalumikizidwa ndi zosefera mpweya, injini yotseka, yomwe imadziwika kuti khosi la injini yamagalimoto.
Kulanda zingwe zinayi za kuponyera mafuta nthawi zambiri kumawoneka ngati chonchi. Throttle ndi imodzi mwazinthu zofunika kwambiri zamakono zamakono zamagetsi zamakono zamagetsi zamagetsi. Mbali yapamwamba yake ndi fyuluta ya mpweya, gawo lakumunsi ndi ma cylinder injini ya injini, ndipo ndi khosi la injini yamagalimoto. Kupititsa patsogolo kwagalimoto kumasinthasintha, ndipo mawonekedwe oyipa amakhala ndi ubale wabwino, kuyeretsa kwamphamvu kumatha kuchepetsa kugwiritsa ntchito mafuta kungapangitse kuti injini ithe kusintha komanso kulimba. Tsoka siliyenera kuchotsedwa kuyeretsa, komanso chidwi cha eni kuti akambirane zambiri
