Imikorere ya piston ikubiyemo gufunga, kugenzura amavuta (kugenzura amavuta), gutwara ubushyuhe (guhererekanya ubushyuhe), kuyobora (inkunga) inshingano enye. Gufunga: bivuga gufunga gaze, ntukemere ko gaze ya chambre yaka yameneka kumuriri, imyuka ya gaze igenzurwa byibuze, kunoza imikorere yubushyuhe. Umwuka uva mu kirere ntuzagabanya ingufu za moteri gusa, ahubwo uzanatuma amavuta yangirika, akaba aricyo gikorwa nyamukuru cyimpeta ya gaze; Hindura amavuta (kugenzura amavuta): amavuta arenze amavuta kurukuta rwa silinderi yarakuweho, kandi urukuta rwa silinderi rutwikiriwe na firime yoroheje kugirango urebe neza ko amavuta asanzwe ya silinderi na piston nimpeta, aricyo gikorwa nyamukuru cya impeta y'amavuta. Muri moteri zigezweho zihuta cyane, hitabwa cyane cyane kubikorwa bya firime ya piston impeta; Gutwara ubushyuhe: ubushyuhe bwa piston bwoherezwa kuri silinderi ikoresheje impeta ya piston, ni ukuvuga ingaruka zo gukonja. Dukurikije amakuru yizewe, 70 ~ 80% yubushyuhe bwakiriwe na piston hejuru ya piston idakonje ikwirakwizwa binyuze mu mpeta ya piston kugeza ku rukuta rwa silinderi, naho 30 ~ 40% bya piston ikonje ikwirakwizwa binyuze mu mpeta ya piston kugeza kuri silinderi. urukuta; Inkunga: Impeta ya piston ituma piston iba muri silinderi, ikabuza guhuza bitaziguye hagati ya piston nurukuta rwa silinderi, ikomeza kugenda neza kwa piston, igabanya ubukana bwo guterana amagambo, kandi ikabuza piston gukubita silinderi. Mubisanzwe, piston ya moteri ya lisansi ikoresha impeta ebyiri za gaze nimpeta imwe ya peteroli, mugihe moteri ya mazutu isanzwe ikoresha impeta ebyiri zamavuta nimpeta ya gaze imwe
