Mhete yePiston idenderedzwa resimbi rinoiswa mugomba repiston. Kune mhando mbiri dzemhete dzepiston: mhete yekumanikidza uye mhete yemafuta. Mhete yekumanikidza inogona kushandiswa kuvhara gasi rinobvira mukamuri rinopisa. Mhete yemafuta inoshandiswa kukwenya mafuta akawandisa kubva musirindiri.
Mhete yepiston imhando yemhete yesimbi inonamira ine deformation yakakura yekunze. Inounganidzwa mugomba re annular rinoenderana neprofile. Mhete dzepiston dzinodzokororwa uye dzinotenderera dzinoshandisa musiyano wekumanikidzwa pakati pegasi kana mvura kuti dzigadzire chisimbiso pakati pedenderedzwa rekunze remhete ne cylinder uye rimwe divi remhete negomba.
Mhete yepiston ndiyo chikamu chikuru cheinjini yemafuta. Inovhara gasi remafuta pamwe chete nesilinda, piston nemadziro esilinda. Injini dzemotokari dzinoshandiswa kazhinji dzine mhando mbiri dzeinjini yedhiziri nepeturu, nekuda kwekuti mashandiro ayo emafuta akasiyana, kushandiswa kwemhete dzepiston hakuna kufanana, mhete dzepiston dzepakutanga nekukanda, asi nekufambira mberi kwetekinoroji, mhete yepiston ine simba guru yakazvarwa, uye nekuvandudzwa kuri kuramba kuchiitwa kweinjini, zvinodiwa nezvakatipoteredza, mhando dzakasiyana dzemashandisirwo ekurapa pamusoro, senge thermal spraying, electroplating, chrome plating, Gas nitriding, physical deposition, surface coating, zinc manganese phosphating treatment, kuitira kuti basa remhete yepiston rive nani zvikuru.
