Kukakamiza stroke: Wagudumu akamafika m'thupi lagalimoto, kutcherako kwa mantha kumazungulira ndipo piston imayenda pansi. Kuchuluka kwa chipinda chotsitsira pisitoni kumatsika ndi kuthamanga kwa mafuta kumakwera. Mafuta amatuluka m'chipinda cha piston kudzera pa valavu yoyenda. Chifukwa cha malo okhala ndi ndodo ya piston, voliyumu yowonjezereka ya chipinda chapamwamba ndi yaying'ono kuposa kuchuluka kwa chipinda chapansi. Ena mwa mafuta amakankhira tsegulani valavu ndikubwerera ku silinda yosungirako mafuta. Kukhumudwa kwa mavuvu izi pamafuta kumapangitsa kuti gulu likhale lophwanya malamulo. Komabe, mu sitiroko, gulu logwedeza nkhawa lomwe limatyler limatcher limakhala laling'ono kuti lithe kukwaniritsa zotsatira za zotanuka ndikuchepetsa mphamvu.
Kuwonjezera stroke: Gudumu likakhala m'thupi lagalimoto, kubzala kwamphamvu kwatambasulidwa ndipo pisitoni imasunthira m'mwamba. Kupanikizika kwamafuta m'chipinda cha piston. Valavu yoyenda imatsekedwa. Mafuta m'chipinda cham'mwamba amalola valavu yowonjezera ndikuyenda m'chipinda chotsika. Chifukwa cha kukhalapo kwa ndodo ya piston, mafuta omwe amayenda kuchokera pachipinda chapamwamba sikokwanira kudzaza kuchuluka kwa chipinda cham'munsi. Vutuli limapangidwa m'chipinda chotsika. Mafuta mu silinda yosungira mafuta amakankhira kutsegulira valavu yolipirira ndikuyenda m'chipinda chotsika kuti chiwonjezere chowonjezera. Mphamvu yosota ya valavu imagwira ntchito yosungirako magwero okumbika. Kuphatikiza apo, gulu lamphamvu lomwe limapangidwa mu sitiroke wowonjezera ndizakukulu kuposa pamenepo m'makamizidwe, omwe amatha kuyamwa mwachangu.
