Impeta ya Piston ni impeta y'icyuma ishyirwa mu mwobo wa piston. Hari ubwoko bubiri bw'impeta za piston: impeta yo gukanda n'impeta y'amavuta. Impeta yo gukanda ishobora gukoreshwa mu gufunga imyuka ivanze mu cyumba cyo gutwika. Impeta y'amavuta ikoreshwa mu gukuraho amavuta arenze kuri silinda.
Impeta ya piston ni ubwoko bw'impeta y'icyuma ifite ubugari bunini bwo kwaguka inyuma. Iteranyirizwa mu mwobo uhuza n'imiterere. Impeta za piston zisubiranamo kandi zizunguruka zishingira ku itandukaniro ry'umuvuduko uri hagati ya gaze cyangwa amazi kugira ngo zikore agafunga hagati y'uruziga rw'inyuma rw'impeta na silindiri n'uruhande rumwe rw'impeta n'uwo mwobo.
Impeta ya piston ni igice cy'ingenzi cya moteri ya lisansi. Ifunga gaze ya lisansi hamwe na silinda, piston n'urukuta rwa silinda. Moteri zikoreshwa cyane zifite ubwoko bubiri bwa moteri ya mazutu na lisansi, bitewe n'uko imikorere ya lisansi itandukanye, ikoreshwa rya piston ntabwo ari rimwe, impeta ya piston ya mbere hakoreshejwe gucukura, ariko hamwe n'iterambere ry'ikoranabuhanga, impeta ya piston ifite imbaraga nyinshi yavutse, kandi hamwe no kunoza imikorere ya moteri, ibisabwa mu bidukikije, uburyo butandukanye bwo gutunganya ubuso, nko gutera ubushyuhe, gukoresha electroplating, gukoresha chrome, gukoresha gaz nitriding, gushyiramo physical, gusiga hejuru, gukoresha zinc manganese phosphating, ku buryo imikorere ya piston irushaho kuba myiza cyane.
