Njengoko iipistons ze-injini yokutsha zisebenza phantsi kobushushu obuphezulu, uxinzelelo oluphezulu kunye neemeko zomthwalo ophezulu, iimfuno zeepistons ziphezulu kakhulu, ngoko ke sithetha kakhulu malunga nokuhlelwa kweepistons ze-injini yokutsha.

1. Ngokwe-fuel esetyenzisiweyo, inokwahlulwa ibe yi-piston ye-injini yepetroli, ipiston ye-injini ye-diesel kunye ne-piston yegesi yendalo.

2. Ngokwempahla yepiston, inokwahlulwa ibe yipiston yentsimbi, ipiston yensimbi, i-aluminium alloy piston kunye nepiston edibeneyo.

3. Ngokwenkqubo yokwenza i-piston blanks, inokohlulwa ibe ipiston yokuphosa umxhuzulane, ipiston ekhamayo, kunye nepiston eqingqiweyo.

4. Ngokweemeko zokusebenza kwepiston, inokwahlulwa ibe ngamacandelo amabini: ipiston engaxinzelelwanga kunye nepiston yoxinzelelo.

5. Ngokwenjongo yepiston, inokwahlulwa ibe yipiston yemoto, ipiston yeloli, ipiston yesithuthuthu, i-marine piston, i-tank piston, ipiston yetrektara, i-lawnmower piston, njl.
