1. Udindo wa mphete
Piston Mphete ndi gawo lofunikira la injini yam'madzi, ntchito zazikulu zimaphatikizapo:

Chisindikizo: amalepheretsa chimpinda cha chipinda cham'madzi kuti chisadutse mu crankcase ndikumapanikizika.

Kusamutsira kutentha: mayendedwe a piston kutentha kwa khoma la silinda kuti athandizire kuziziritsa.

Kuwongolera Mafuta: Sinthani kuchuluka kwa mafuta odzola pa khoma la silinda kuti mupewe mafuta ambiri kuti asalowe m'chipinda chocheka.

Chithandizo: chimachepetsa mikangano ndikuvala piston ndi khoma la silinda.

2. Mtundu wa mphete ya piston
Mphete ya mpweya (kuphatikiza mphete): Kugwiritsa ntchito kusindikiza botolo la chipinda kuti mupewe kutaya.

Mphete ya mafuta: imayendetsa mafuta opangira mafuta pagodi la silinda kuti muchepetse mafuta ochulukirapo kuti asalowe mchipinda chocheka.

3. Zipangizo ndi kupanga
Zipangizo: Zipangizo zomwe zimagwiritsidwa ntchito zimaphatikizanso chitsulo, chitsulo, chitsulo, ndi zina zambiri, muyenera kuvala kwambiri kukana, kukana kutentha ndi mphamvu.

Kupanga Kopanga: Kutulutsa koyenera, kuchiritsa kutentha ndi chithandizo chamatenthedwe (monga mankhwalawa (monga ma chrome), nitring) nthawi zambiri amagwiritsidwa ntchito kukonza magwiridwe antchito.
