Kurongwa nechimiro chechimiro kumusoro kwepiston
① flat top piston: inokodzera pre-combustion combustion chamber ye carburetor engine uye turbocurrent combustion chamber ye diesel engine.Iyo inobatsira iri nyore kugadzira, yepamusoro inotakura yunifomu yekugovera kupisa, uye diki piston quality.
② concave top piston: inogona kuvandudza musanganiswa liquidity uye combustion kushanda kwedhiziri kana mamwe peturu injini.Kubatsira ndiko nyore kuchinja compression reshiyo uye combustion chamber chimiro.
③ convex yepamusoro piston: kuitira kuvandudza reshiyo yekumanikidza, kazhinji yakakodzera kune yakaderera-simba injini.

Nechimiro chesiketi
① skirt slot piston: inokodzera injini dzine diki cylinder dhayamita uye yakaderera gasi kumanikidzwa. Chinangwa che slotting ndechekudzivirira kuwedzera, inozivikanwawo sepiston elastic.
② siketi isina kuvharwa piston: inonyanya kushandiswa mumainjini emarori makuru ematani.Inozivikanwawo sepiston yakaoma.

Classification nepiston pin
① piston uko pini chigaro axis inopindirana nepiston axis.
② piston pin seat axis perpendicular kune piston axis.
