Iyo elastic simba yepiston mhete chinhu chakakosha chinokanganisa jekiseni remafuta epombi yekupedza. Iyo elasticity yepiston mhete inogona kuongororwa nechirimo tester kana nzira yekuenzanisa. Panguva ino, mhete yepiston yekare uye mhete yepiston inogona kusimudzwa pamwechete, uye kumanikidza kunogona kuiswa kubva kumusoro neruoko. Kana zviteshi zvekare zvemhete zvichisangana uye zviteshi zvitsva zvemhete zvichine gaka rakakura, zvinoreva kuti mhete yepiston haina kusimba. Tarisa kuonana uye kuvharika kwemhete yepiston uye cylinder liner: Isa piston ring flat mucylinder liner, isa girobhu remwenje pasi pemhete yepiston, uye isa nhovo mwenje pairi kuti ucherechedze kubuda kwechiedza uye chisimbiso degree re mhete yepiston mucylinder liner.

Chinodiwa chakajairika ndechekuti kana uchiyera gaka rekudonha kwemwenje wepiston negeji ukobvu, haifanirwe kudarika 0.03mm. Iyo piston mhete inotenderera nekuda kwekudengenyeka panguva yekushanda. Izvi zvinowanzoitika. Injini ichangobva kuisa cylinder liner pakuisa piston yekubatanidza rod assembly. Chero bedzi zvindori zvepiston zvakavharwa pakona yakatemwa, kuvhurwa kwemhete dzepiston hakutenderere kuti kupindirana. Kana cylinder liner ichigadzira ellipse uye taper nekuda kwekupfeka kwechidimbu kana kupfeka kwakanyanya kwepiston, zvinokwanisika kuita kuvhurwa kwepiston mhete kutendeukira kune imwechete nzira kusvika ellipse. Nekuti panguva ino, nekuda kwe ellipse ye cylinder liner, kuwedzera kwepiston ring kuvhurwa kunodzivirirwa kubva kutenderera, zvichiita kuti mazaru emhete apinde zvishoma nezvishoma, gasi rinodonha richidzika, uye injini yemafuta inopukunyuka ichikwira uye inoburitswa.

Kana tsvimbo yekubatanidza yakamonyoroka nekuremara, kubvisirwa pakati pepiston necylinder seti kwakakurisa, uye gaka rekuvhurwa remhete yepiston rakakura kwazvo, rinogona kukonzera kubuda kwemhepo, zvichikonzera kutamiswa kwemhete yepiston kuita vaviri. EQ6100-1 injini piston mhete yekutsiva nguva: pakati peaviri ekugadzirisa injini, motokari inofamba anenge 80,000 km, iyo yakaenzana ne 0.15mm ye cylinder cone kupfeka, kana kupera kwepiston mhete inodarika 2mm; injini simba Kushanda kunodonha zvakanyanya, kushandiswa kwemafuta uye mafuta ekuzora kunowedzera zvakanyanya, iyo spark plug inowanzoitika kune kabhoni deposits, uye mhete yepiston inoputika. Pakusarudza mhete yepiston, mhete yepiston yegiredhi rakafanana nepiston inofanira kushandiswa.
