Njengoba ama-pistons enjini evuthayo asebenza ngaphansi kwezinga lokushisa eliphezulu, ingcindezi ephezulu kanye nezimo zomthwalo ophezulu, izidingo zamaphistoni ziphakeme kakhulu, ngakho-ke sikhuluma kakhulu ngokuhlukaniswa kwamapiston enjini evuthayo yangaphakathi.

1. Ngokusho kukaphethiloli osetshenzisiwe, ungahlukaniswa ube yi-piston yenjini kaphethiloli, i-diesel engine piston kanye ne-natural gas piston.

2. Ngokwempahla ye-piston, ingahlukaniswa ibe i-cast iron piston, i-piston yensimbi, i-aluminium alloy piston kanye ne-piston ehlanganisiwe.

3. Ngokwenqubo yokwenza izikhala zepiston, ingahlukaniswa ibe i-gravity casting piston, piston ekhamayo, nepiston engumgunyathi.

4. Ngokwezimo zokusebenza ze-piston, ingahlukaniswa ngezigaba ezimbili: i-piston engacindezelwe kanye ne-piston ecindezelweyo.

5. Ngokwenhloso ye-piston, ingahlukaniswa ibe i-piston yemoto, i-piston yeloli, i-piston yesithuthuthu, i-marine piston, i-tank piston, i-tractor piston, i-lawnmower piston, njll.
