Ukwahlula ngokwendlela yesakhiwo phezulu kwipiston
① Ipiston ethe tyaba ethe tyaba: ilungele indawo yokutsha yangaphambili ye-injini ye-carburetor kunye negumbi lokutshisa i-turbocurrent ye-injini ye-diesel.I-advanteji kulula ukuyenza, i-top bears ithwala ukuhanjiswa kobushushu obufanayo, kunye nomgangatho wepiston encinci.
② i-concave top piston: inokuphucula umbane kunye nokusebenza kokutsha kwedizili okanye iinjini zepetroli.
③ Ipiston yeconvex ephezulu: ukuze kuphuculwe umlinganiselo woxinzelelo, ilungele iinjini zamandla aphantsi ngokubanzi.

Ngokwesakhiwo se-skirt
① i-skirt slot piston: ilungele ii-injini ezinobubanzi obuncinci be-cylinder kunye noxinzelelo oluphantsi lwegesi.Injongo yokubeka i-slot kukuphepha ukwandiswa, okwabizwa ngokuba yi-piston elastic.
② isiketi sepiston engavulekanga: isetyenziswa kakhulu kwiinjini zeelori ezinkulu zeetoni.Kwaziwa ngokuba yipiston eqinileyo.

Ukwahlulahlula ngepiston
① ipiston apho i-axis yesitulo isikhonkwane inqumla iasi yepiston.
② ipiston yesitulo sesitulo se-piston ehambelana ne-axis yepiston.
